INTRODUCTION
Ancylolomia Hübner, 1825 is the main genus of tribe Ancylolomiini Ragonot.It experienced important evolutionary success in the Old World and particularly in the Afrotropics.Recent genetic studies (Léger et al., 2019) highlighted that the Ancylolomiini should enclose the Prionapterygini Landry (1995: 56).However, Ancylolomia and genera strictly related to it, as summarized in Bassi (2013), have morphological characters that easily distinguish them from the Prionapteryx complex of genera.The Afrotropical fauna of Ancylolomia and allied genera were never reviewed, except for two small species groups of Ancylolomia (Bassi, 2013) and some other small genera (Bassi, 2021;Bassi et al., 2021).This paper treats the species of the characteristic Ancylolomia prepiella complex of species in the A. inornata group as identified in Bassi & Trematerra (2014); it includes only the well-characterized species known to me as many species that I have identified as new are not described here due to the lack of sufficient material or the difficulty in correctly assigning males and females.Also, many other species are certainly still waiting to be discovered.

MATERIAL AND METHODS
Genitalia preparations were made following Robinson (1976).The terminology of the genitalia follows Błeszyński (1970) and Bassi (2013).Genitalia photographs were taken with a Canon S120 digital camera.Ratios of structures were recorded with the aid of a micrometric slide.The habitus photos were made with a Nikon D3300 digital camera.The images were enhanced with Adobe Photoshop Elements.The following abbreviations are used: 'SB' for Stanisław Błeszyński, 'DRC' for Democratic Republic of the Congo', 'GB' for Graziano Bassi, 'GS' for genitalia slide', 'm' for meter(s), 'HNHM' for Hungarian Natural History Museum, Budapest, Hungary, 'RCGB' for Graziano Bassi Research Collection (to be deposited in MHNG), Avigliana, Italy, 'ISAM' for Iziko South African Museum, Cape Town, RSA, 'MfN' for Museum für Naturkunde, Leibniz-Institut für Evolutions-und Biodiversitätsforschung, Berlin, Germany, 'MHNG' for Muséum d'histoire naturelle de Genève, Geneva, Switzerland, 'NHMUK' for Natural History Museum, London, UK, 'RSA' for Republic of South Africa,

Ancylolomia Hübner, 1825
Genus Ancylolomia Hübner (type species Tinea palpella Denis & Schiffermüller, 1775) includes 70 species from almost all over the Old World, reaching eastward to Australia with a single species.The Afrotropical region presently includes 36 species (Nuss et al., 2023), mainly referable to the inornata group of species (Błeszyński, 1970;Bassi, 2013).Among the inornata group, the prepiella complex of species is characterized by female genitalia with a lateral extension of the corpus bursae, usually thin, or globular in A. arabella Błeszyński and A. sophia sp. nov.The female genitalia also present two types of papillae anales: type A (Fig. 1), large and strongly covered with setae and type B (Fig. 2), narrower and less covered with setae; the ductus seminalis is opening basally on the corpus bursae; the corpus bursae is always suboval and delicately wrinkled basally.Male genitalia have the phallus strongly curved and very long, often longer than the whole apparatus; the uncus and gnathos are of two types: type C (Fig. 3), both slender and longer than half the tegumen, and type D (Fig. 4), both shorter than half the tegumen and with the uncus stouter than in type C; the tegumen is typical of the inornata group, i.e. slender, subtriangular and basally enlarged.Adults are generally small moths, of a wingspan from 12 to 32 mm, but mostly around 20 mm, with ocelli and chaetosemata fully developed.Their wing markings have the typical pattern of Ancylolomia (Bassi, 2013) and it is usually difficult to distinguish the species from one another.However, the subterminal area of the forewing, especially, but also the length of the labial palpus and the shape of the antenna in the male (Figs 28-30) can help in the determination.Both male and female genitalia are, on the other hand, very characteristic and allow for easier distinction of the species.However, the problem of correctly associating males and females collected individually often remains, even in the same locality or in localities close to each other.Although Ancylolomia species have been reported to feed on various Poaceae (Robinson et al., 2010), the biology of the species treated here is yet unknown.Adults are nocturnal and are easily attracted to light.

Etymology:
The new species is named after Georges Audéoud (Geneva, Switzerland, 1874-Chêne-Bourg, Switzerland, 1943), the collector of the holotype and of valuable additional Lepidoptera material in Africa in the first decades of the 1900's.

Diagnosis:
The adult of this species can be distinguished from congeners with a pure white hindwing by the short labial palpus, and, on the forewing, by the narrow medial stripe, the welldefined brown lines along the veins on both upper and underside, and the strongly jagged subterminal line.The female genitalia are unique in having the apophyses posteriores with an ear-like bulge and the lateral extension shaft sclerotized for 2/3rds of its length.
Wings with pattern and colours as illustrated (Fig. 14).
Underside of forewing off-white, yellowish-white along costa and brown medially and along veins.Underside of hindwing white, suffused with yellow along costa.Legs brown with inner side off-white; tibial spurs minute, the external half as long as the internal.
Apophyses posteriores three times longer than apophyses anteriores, with ear-like bulge basally.Abdominal segment VIII well developed, dorsally and laterally less sclerotized.Sterigma produced, rounded.Ductus bursae as long as corpus bursae, narrower medially.Lateral extension thin, shaft sclerotized for 2/3rds of its length, three times as long as corpus bursae, bulged distally.Male unknown.
Distribution: Known only from the type locality.

Etymology:
The species is dedicated to my wife, Fiorenza, patient partner in life and in most of my travels through Africa and Europe.

Diagnosis:
The adult has the same wingspan and is most similar in pattern to A. parentii (Fig. 8), but it differs in having the vertex mainly white instead of brown and an indentation in the subterminal fascia at the end of CuA2 in the forewing (Fig. 11, arrow).The male genitalia have the gnathos less upcurved, the costa apically more distinct, the vinculum dorsally longer and the phallus less curved and with the cornutus longer than in A. parentii (Bassi & Trematerra, 2014, fig. 2D).
In female genitalia the long and narrow lateral extension associated with the concave sterigma and the apophyses posteriores basally enlarged are unlike those of any other congener.
Wings with pattern and colours as illustrated (Fig. 11).Underside of forewing pale brown suffused with yellow with subterminal area white.Underside of hindwing white suffused with brown.Legs brown with inner side white; tibial spurs slender, the external half as long as the internal.

Etymology:
The new name doesn't refer to any person in particular.

Diagnosis:
The adult is similar to that of A. anna (Fig. 12), but is larger and differs in the forewing with a darker subterminal area and no dark costal spot close to the subterminal line (Fig. 6, arrow).The male genitalia are distinguished by the larger valva (width/length ratio 0.42 vs 0.28 for A. anna), the costal process with a more pointed tip, and the phallus with the cornutus apically more rounded than in A. anna (Fig. 31).In the female genitalia the broadly convex sterigma and the short lateral extension are unlike any other allied species.
Description: Wingspan: males 18 mm, females 24 and 25 mm.Labial palpus 2.1 X eye diameter, narrow, brown with inner side paler.Maxillary palpus thin, brown.Antenna serrate in male, filiform in female, brown with costa bright pale brown.Frons rounded, slightly produced, brown sprinkled with pale brown.Vertex pale brown, brown medially and between antennae.Patagium pale brown, darker laterally.Tegula pale brown sprinkled with brown.Thorax brown.
Wings with pattern and colours as illustrated (Fig. 6).Underside of forewing off-white suffused with yellow along costa and with brown medially and along veins.Underside of hindwing white suffused with yellow especially along veins.Legs ivory yellow; tibial spurs slender, the external slightly shorter than the internal.Male genitalia (Fig. 32).Uncus and gnathos of type C, apically slightly curved, with rounded tip.Vinculum 0.6 X as long as valva, distally rounded.Pseudosaccus sub conical.Juxta 0.9 X as long as vinculum, with distal symmetric sclerotized arms.Valva narrowing

Etymology:
The new name doesn't refer to any person in particular.

Diagnosis:
The adult habitus, dark brown and chestnut brown in the forewing and dark brown in the hindwing, distinguishes A. isabella from all other congeners.In male genitalia, the stout uncus, the narrow and pointed gnathos, and the strong and very long costal process are distinctive features; in female genitalia the lateral extension sclerotized up to the apical bulge is unique among related species.

Etymology:
The name refers to a Latin woman's name, without referring to any person in particular.

Diagnosis:
The adult differs from those of allied species in having the male antenna strongly serrate and the forewing brown costal margin enlarging distally, close to the subterminal line.In the male genitalia the strongly developed costal process and the strongly curved phallus with the cornutus relatively short and narrowing distally distinguish A. lavinia from allied species.
Description: Wingspan: males 18 mm.Labial palpus 2.5 X eye diameter, narrow, brown.Maxillary palpus subtriangular, brown.Antenna slightly serrate (Fig. 28), brown with costa bright brown.Frons rounded, slightly produced, brown.Vertex pale brown, with scales basally pale brown.Patagium pale brown, darker laterally.Tegula pale brown.Thorax pale brown with bottom edge off-white.Wings with pattern and colours as illustrated (Fig. 16).Underside of forewing brown suffused with yellow especially along costa; subterminal area off-white.Underside of hindwing white with veins and terminal line yellow.Legs pale brown, ivory yellow on inner side; tibial spurs narrow, the external 0.3 as long as the internal.Male genitalia (Fig. 33).

Etymology:
The new species takes its name from that of a Naiad nymph of the Greek mythology.
Diagnosis: Ancylolomia lotis is on average slightly larger and paler than A. lydia (Fig. 23).The male genitalia of A. lotis can be distinguished from those of A. lydia (Fig. 35) by the uncus and gnathos, which are broader and more curved in A. lydia, the costal process of the valva, which is longer and more curved in A. lydia, and the apical spine of the phallus, which is shorter in A. lydia.

Etymology:
The new species derives its name from that of the type locality and is treated as a noun in apposition.

Diagnosis:
The adult of A. lucia is most similar to those of A. trematerrai and A. lydia; it is distinguishable in having longer palpi than A. lydia, and the forewing subterminal area has a paler inner line, with a triangular marking on vein M1 facing backward (Fig. 21, arrow), whereas this line is jagged with markings pointing forward in A. lydia (Fig. 23, arrow) and with brown triangular markings in A. trematerrai (Fig. 22, arrow).
The female genitalia are similar to those of A. lydia, but in A. lucia the papillae anales are larger and more intensely covered with setae, the apophyses posteriores are basally smaller, the apophyses anteriores are shorter and stouter, the ductus bursae is shorter and larger, and the lateral extension is narrower and shorter.
Description: Wingspan 22 mm.Labial palpus 3.5 X eye diameter, brown.Maxillary palpus subtriangular, brown with inner side paler.Antenna slightly thickened, brown with costa bright brown.Frons rounded, slightly produced, brown.Vertex brown sprinkled with offwhite.Patagium brown, paler medially.Tegula brown sprinkled with cream brown.Thorax brown.Wings with pattern and colours as illustrated (Fig. 21).Underside of forewing pale brown sprinkled with off-white with subterminal area white.Underside of hindwing brown suffused with off-white.Legs pale brown with inner side paler; tibial spurs slender, the external slightly shorter than the internal.
Apophyses posteriores three times as long as the stout apophyses anteriores.

Etymology:
The name refers to a Latin woman's name, without referring to any person in particular.
Diagnosis: Ancylolomia lydia is slightly smaller and darker than A. lotis, with a better defined off-white medial stripe in the forewing.It is also very similar to A. trematerrai and A. lucia, but it differs in having shorter palpi than in both of these species, and the forewing subterminal area's inner jagged line has markings pointing forward on veins R4-M1 (Fig. 23, arrow), whereas this line is almost straight with only a tooth facing backwards in A. lucia (Fig. 21, arrow), and with brown triangular teeth in A. trematerrai (Fig. 22,arrow).The male genitalia of A. lydia can be distinguished from those of A. lotis (Fig. 34) by the smaller uncus and gnathos, the shorter and straighter costal process of the valva, and the shorter apical spine of the phallus.The female genitalia of A. lydia are very similar to those of all species with papillae anales of type A, but the lateral extension is 1.7 times the length of the corpus bursae, as opposed to various other lengths in the other species.

Etymology:
The new species derives its name from that of the type locality and is treated as a noun in apposition.
Diagnosis: Ancylolomia maria is distinguished from A. shingwedzi (Fig. 20), the other species flying in Northern Limpopo, by a paler forewing ground colour, larger medial stripe, and more jagged brown subterminal line.The male genitalia are similar to those of A. fiorenzae (Fig. 37) in the long phallus, but in A. maria the cornutus is stronger and the costal process is much more strongly developed than in A. fiorenzae.
Description: Wingspan 20 mm.Labial palpus narrow, 2 X longer than widest diameter of eye, brown with inner side pale brown.Maxillary palpus thin, brown.
Antenna densely serrate, brown with costa bronze brown.Frons rounded, slightly produced, ochre brown.Vertex off-white sprinkled with pale brown.Patagium pale brown.Tegula brown sprinkled with pale brown.Thorax pale brown.Wings with pattern and colours as illustrated (Fig. 19).Underside of forewing brown, yellowish brown under costa and with subterminal area white with markings as on upper side.Underside of hindwing white suffused with brown along costa.Legs yellowish brown with inner side white; tibial spurs slender, the external one third as long as the internal.
Female unknown.

Etymology:
The name refers to the distributional area of the species.

Diagnosis:
The adult is unique in having a strongly produced frons, strongly jagged inner subterminal line and abdominal segment VIII with two strongly sclerotized sclerites contained in a fold at its apex.The male genitalia are distinguished by stouter uncus and gnathos, a particularly stocky tegumen, a narrow valva and a more strongly curved and twisted phallus than in all other congeners.
Description: Wingspan: 18-26 mm, the specimen from Angola the largest, the others 18-22 mm.Labial palpus 2.5 X as long as widest diameter of eye, pale brown.Maxillary palpus thin, brown.Antenna serrate, brown with costa bright pale brown.Frons rounded from above, subconical in lateral view, strongly produced, brown.Vertex pale brown.Patagium pale brown, darker laterally.Tegula brown with edge paler.Thorax pale brown with narrow brown medial line.Wings with pattern and colours as illustrated (Fig. 9).Underside of forewing off-white, yellowish brown under costa, bright brown medially and with subterminal area white.Underside of hindwing white suffused with brown near costa and with veins pale yellow.Abdomen bright white with tergites I-IV suffused with orange-yellow; sternites white suffused with yellow, medially more intensely so.Legs pale yellow with inner side white; tibial spurs slender, the external 0.3 as long as the internal.Sclerites of abdominal segment VIII as on Fig. 44.Male genitalia (Fig. 44).Uncus and gnathos of type D, stout, apically slightly curved, uncus with blunt tip and gnathos with stocky tip.Vinculum 0.3 as long as valva, distally rounded.Pseudosaccus elongated, enlarged basally.Juxta as long as vinculum.Valva long and narrow, with width length ratio of 0.3; costa gently concave, thickened for 0.9 of its length, without costal process; fold of areola overlapping cucullus, the longest sensorial scales 0.3 as long as valva.Phallus concave and twisted, vesica with cornutus 1.2 as long as whole apparatus, with pointed apex.Female unknown.

Remarks:
The distal pattern of the forewing is shown on Fig. 8.The in-depth study of the species complex leads me to the conviction that the uncus and gnathos of type C are related to the papillae anales of type A as those of type D are to the papillae anales of type B. In fact, the study of additional specimens of A. parentii collected in RSA and eSwatini allows me to describe the female while the single paratype originally described as A. parentii belongs to the new species A. trematerrai, described below.
Ancylolomia prepiella Hampson, 1919 Figs 26, 42, 53 Remarks: This is the largest species of the complex (28-36 mm).The adult male is figured in Bassi (2021: 478, fig.5), the distal pattern of the forewing is shown on Fig. 26, and the genitalia are illustrated on Figs 42 and 53.

Etymology:
The new species derives its name from that of the type locality, and is treated as a noun in apposition.

Diagnosis:
The adult of A. sakania can be distinguished from congeners by the short labial palpi, the pale thorax with a brown medial line, the forewing with a large medial stripe ending before the end of the cell, the almost straight and slightly jagged subterminal line, and the large silvery line of the short scales of the fringes.
The male genitalia are similar to those of A. fiorenzae (Fig. 37), but the uncus is more strongly downcurved, the gnathos is stouter, the vinculum is shorter, and the costal process of the valva is much more strongly developed.
Description: Wingspan 20 mm.Labial palpus 2.5 X longer than widest diameter of eye, brown.Maxillary palpus triangular, brown.Antenna strongly serrate, brown with costa off-white.Frons rounded, slightly produced, brown.Vertex pale brown.Patagium and tegula pale brown.Thorax pale yellow with narrow medial line brown.Wings with pattern and colours as illustrated (Fig. 24).Underside of forewing brown, yellowish brown under costa and with subterminal area off-white.Underside of hindwing white suffused with pale yellow.Abdomen with tergites I-IV orange-yellow, then ivory yellow; sternites ivory yellow, medially suffused with grey.Legs pale brown with inner side offwhite; tibial spurs slender, the external 2/3 as long as the internal.

Etymology:
The new species derives its name from that of the type locality.

Diagnosis:
The adult of A. savutiensis is paler than in allied species except for A. medioafricana (Fig. 9), but it differs in the forewing with the subterminal inner line almost straight and in the sandy brown hindwing, whereas the forewing subterminal inner line is strongly jagged and the hindwing is off-white suffused with pale yellow in A. medioafricana.The male genitalia are unlike others in the stout costal process of the valva and the long phallus with a slender cornutus.
Description: Wingspan 20-23 mm.Labial palpus 2.5 X as long as widest diameter of eye, creamy brown with inner side off-white.Maxillary palpus triangular, creamy brown.Antenna strongly serrate, brown with costa bronze brown.Frons rounded, slightly produced, brown.Vertex off-white suffused with pale brown.Patagium sandy brown, brown medially.Tegula sandy brown with edge creamy brown.Thorax pale brown with narrow medial line sandy brown.Wings with pattern and colours as illustrated (Fig. 10).Underside of forewing brown suffused with yellow, white from cell to termen.Underside of hindwing off-white suffused with pale brown and yellow.Abdomen with tergites yellow, more intense on first four segments; sternites off-white with medial band brown.Legs pale yellow with inner side white; tibial spurs slender, the external half as long as the internal.

Etymology:
The name of new species is derived from that of the type locality and is treated as a noun in apposition.

Diagnosis:
Along with A. isabella (Fig. 13), A. shingwedzi can be distinguished from the other species of the complex by having the darkest forewing ground colour; it differs from A. isabella by the sandy grey forewing without olive green suffusion and the much paler hindwing.The female genitalia differ in the lateral extension with a basal sickle-shaped sclerotization and with a large duct, narrowing only after half of its length.

Etymology:
The new name doesn't refer to any person in particular.

Diagnosis:
The adult differs from that of allied species in the forewing with strongly jagged subterminal line toward apex and the pure white hindwing.The male genitalia differ from those of allied species in the large valva with a pointed and upcurved costal process and the stout and strongly curved phallus.The female genitalia are similar to those of A. vanessa (Fig. 49) in the large sterigma and the strongly narrowing ductus bursae medially, but A. sonia has much longer and basally thickened apophyses posteriores, and a much longer lateral extension.Diagnosis: Ancylolomia trematerrai is most similar to A. lucia (Fig. 21) and A. lydia (Fig. 23) and is distinguishable in having longer labial palpi than A. lydia, and the inner line of the subterminal area with brown triangular spots, especially evident at the level of the largest spot at the end of the Cu1 vein (Fig. 22, arrow), whereas this line is only jagged in A. lucia and A. lydia.Ancylolomia parentii (Fig. 8) is similar in also having a dark hindwing, but its forewing has a grey brown ground colour as opposed to a yellow brown ground colour in A. trematerrai, and it lacks the brown triangular spots of the inner line of the subterminal area.

Etymology:
The new name doesn't refer to any person in particular.

Diagnosis:
The adult forewing with the costa and medial area yellowish to yellowish brown and the dorsum and postmedial fascia greyish brown place A. vanessa near A. sophia (Fig. 15), but the latter is smaller (23 mm in wingspan) and yellower.The female genitalia are close to A. greta and A. lydia, but the papillae anales are narrower, the sterigma is larger and more sclerotized, and the lateral extension is shorter.
Description: Wingspan 27 mm.Labial palpus 2 X longer than widest diameter of eye, brown.Frons rounded, brown.Vertex, tegula and thorax brown sprinkled with pale brown.Wings as illustrated (Fig. 17).Underside of forewing brown basally, medially and along veins, white dorsally and distally.Underside of hindwing white with costa suffused with brown and veins pale yellow.Abdomen basally dark brown, tergites 1-2 orange brown, then pale brown; sternites brown.Anal tuft ivory yellow.Legs brown, ivory yellow inside; tibial spurs delicate, the external 0.75 the length of the internal.

Etymology:
The name of the new species is derived from that of the type locality and is treated as a noun in apposition.
Diagnosis: Ancylolomia victoria is easily distinguishable from congeners in its very serrate antenna, and yellowish brown forewing ground colour with black brown dorsum and white subterminal area with the inner line almost straight, ochre brown.The male genitalia are unique among species with the uncus and gnathos of type C in lacking a produced costal process.The female genitalia are characterized by the concave sterigma, the large ductus bursae and the lateral process only shortly sclerotized, features never present all together in congeners.
Description: Wingspan of males 24 mm, female 28 mm.Labial palpus 2.2 X longer than widest diameter of eye, brown with inner side paler.Maxillary palpus half as long as labial palpus, pale brown.Antenna serrate in male, filiform in female, brown with costa paler.Frons rounded, slightly produced, brown.Vertex, tegula, patagium and thorax brown sprinkled with dark brown.Wings as illustrated (Fig. 18).Underside of forewing yellowish brown with subterminal area white.Underside of hindwing white heavily suffused with brown.Abdomen yellow with tergites 1-2 orange brown.Legs grey brown with tibial spurs delicate, the external half as long as the internal.Female more suffused with grey, both in fore-and hindwing.Male genitalia (Fig. 36).Uncus and gnathos of type C; uncus almost straight, with rounded tip; gnathos distally straight, with raised medial lamella close to rounded apex.Vinculum 0.8 as long as valva, distally rounded.Pseudosaccus small, subrectangular.Juxta suboval, as long as vinculum.Valva with costa only thickened and slightly produced before cucullus; fold of areola overlapping cucullus, the longest sensorial scales 0.3 as long as valva.Phallus as long as whole apparatus, slightly concave, vesica with cornutus as long as phallus shaft.
Female genitalia (Fig. 51).Papillae anales of type A, with upper edge concave.Apophyses posteriores twice as long as apophyses anteriores.Abdominal segment VIII large, with upper edge straight.Sterigma concave, produced.Ductus bursae large, 0.45 as long as corpus bursae.Lateral extension large, 2.5 times as long as corpus bursae, with oval bulge apically and with duct half sclerotized up to 0.25 of its length.
Distribution: Only known from the type locality in Zimbabwe.

Remarks:
The female, even if collected along with the two males, could be incorrectly associated to A. victoria since the specimen is in rather poor condition and does not allow an in-depth analysis of the forewing pattern.
