Type species: Nasoona prominula Locket, 1982 by original designation.

Taxonomic remarks: The genus includes medium-sized erigonines with a variegated abdomen and, in most cases, with a postocular elevation on the male carapace bearing a group of curved, spines, stout spines or setae.

Three species lack this carapace elevation: N. asocialis (Wunderlich, 1974), N. chrysanthusi Locket, 1982 and a new species described below.

The chaetotaxy formula is 2.2.1.1. Two exceptions given in the literature, 1.1.1.1 in N. coronata (Simon, 1894) and 1.1.1.1 in the male of N. locketi Millidge, 1995, are mistakes based on incomplete spination caused by partial loss of spines. Each metatarsus is with a trichobothrium, except for N. coronata.

The male palp is characterized by the following features:

The epigyne in Nasoona is typical for many erigonines and represented mostly by a shallow epigynal cavity which is sometimes divided by a septum and in a few species partially covered from above by an overhanging, visor-like outgrowth of the anterior epigynal wall. Receptacles are relatively small, subspherical or beanlike.

The position of the genus within the Erigoninae is unclear, but some somatic characters, i.e. chaeto- and trichobothriotaxy, modified male carapace, as well as genitalia conformation show similarity with Gongylidioides Oi, 1960 and in part Oedothorax.

Species included: Excluding one species which is removed from Nasoona, the genus currently comprises 17 species, 6 of them are described as new below.

Distribution: Extreme south of the Palaearctic Region: Nepal Himalayas and southern China; throughout the Oriental Region; Neotropical Region: Venezuela.

Range: Disjunct Oriental-Neotropical.

Holotype: Male; INDIA, West-Bengal, Darjeeling District, Ghoom, Tigerhill, southern slope, 2200–2300 m a.s.l., sifting in forest; 13.X.1978; leg. C. Besuchet & I. Löbl [#13].

Diagnosis: According to the male palpal conformation, N. indianа sp. nov. seems to be most similar to N. setifera (Tanasevitch, 1998), known from a single locality in the mountains of Nepal (Tanasevitch, 1998). The new species differs by the bifid distal apophysis of the convector, by the slender distal process of the paraconvector which was erroneously named the suprategular apophysis (Tanasevitch, 1998), as well as by the shape of the carapace. The carapace of N. indianа sp. nov. has a small, conical postocular elevation bearing a stout seta, while in N. setifera the carapace is armed with several stout, bent spines and a seta situated on a huge postocular elevation. The shape of the carapace and the structure of the embolic division of N. indianа sp. nov. is also similar to that of N. conica (Tanasevitch, 1998), known from high altitudes of the Nepalense Himalayas, but the new species differs clearly by the shape of its palpal tibia.

Etymology: The specific epithet, a Latinized adjective, is derived from the name of the country of origin, India.

Description: Male (holotype): Total length 2.01. Carapace 1.13 long, 0.90 wide, pale reddish brown, with grey radial stripes and a narrow margin. Behind posterior median eyes a conical elevation with a socket terminally, indicated with arrow in Fig. 3, probably for a large, stout seta which was lost in this specimen (Figs 1–3). Chelicerae 0.55 long, unmodified. Legs yellow. Leg I 4.38 long (1.25+0.30+1.13+10.05+0.65), IV 4.44 long (1.25+0.28+1.13+1.15+0.63). Chaetotaxy: spines mostly lost, but probably 2.2.1.1. Each metatarsus with a trichobothrium. TmI 0.71. Palp (Figs 28–33): Tibia slightly expanded distally, with several very short spinules terminally. Retrolateral side of tibia with a tooth-like tubercle, prolateral side with a small dark protuberance and two larger keel-shaped outgrowths. Proximal part of paracymbium narrow, distal part expanded and bearing several weak spines. Tegulum terminating in transparent protegulum. Distal suprategular apophysis short, wide, T-shaped distally, bearing a black, sharp tooth in middle. Embolus long and thin, forming a loop, radix reduced. Main body of convector relatively narrow, twisted, its distal apophysis well-sclerotized, black, bifid. Paraconvector large, complicated, with a long, sabre-shaped distal process. Abdomen 1.40 long, 0.88 wide, dorsal pattern as in Fig. 1.

Female: Unknown.

Distribution: Only known from the type locality in the mountains of West-Bengal, India.

Holotype: ZMMU; male; INDIA, Odisha State (= Orissa before 2011), road from Banigocha to Daspalla, near Padiakutibari, 20.382°N 84.771°E; 17.-25.I.2014; leg. K. Tomkovich.

Paratypes: ZMMU; 3 males; MHNG; 2 males; collected together with the holotype.

Diagnosis: The new species is characterized by the peculiar shape of the male papal tibia, by the distal apophysis of the convector which is divided into two lobes, as well as by a wide, strongly bent distal process of the paraconvector. The massive distal apophysis of the convector, as well as the shape of the distal process of the paraconvector of N. orissa sp. nov. resemble those of N. crucifera, which is widespread in the Oriental Region, but both species are clearly distinguished by the structure of the palpal tibia. The shape of the convector, as well as the strongly divided palpal tibia are similar to those of N. sulawesi sp. nov., but N. orissa sp. nov. can be easily distinguished by the shape of the distal process of the paraconvector.

Etymology: The specific epithet is a name in apposition referring to the “terra typica”, the old name of the Odisha State in India.

Description:

Male (paratype): Total length 1.70. Carapace 0.75 long, 0.60 wide, pale brown, with a postocular elevation bearing bent, forward-directed, stout spines as shown in Fig. 4; eyes normal. Chelicerae 0.33 long, unmodified. Legs yellow. Leg I 2.61 long (0.70+0.18+0.68+0.63+0.42), IV 2.69 long (0.75+0.18+0.70+0.68+0.38). Chaetotaxy: 2.2.1.1, length of spines about 1.5–2.5 diameters of leg segment. Each metatarsus with a trichobothrium. TmI 0.52. Palp (Figs 34–41): Tibia divided into four lobes: prolateral one keel-shaped; dorso-prolateral one long, narrowing at middle; dorso-retrolateral one conical, with several very short spinules terminally; retrolateral outgrowth wide, forming a shallow cup. Proximal part of paracymbium narrow, L-shaped; distal part wide, ending in a hook. Distal suprategular apophysis short, flat, with a sharp, black tooth in middle. Embolus long and thin, forming a loop, radix reduced. Main body of convector relatively narrow, curved; its distal apophysis black, well sclerotized, divided into two uneven lobes with serrate walls. Paraconvector massive, complicated, with serrate edges and distinctly protruded distal process. Abdomen 1.00 long, 0.60 wide, dorsally white, with three longitudinal pairs of large, grey spots.

Female: Unknown.

Distribution: Only known from the type locality in western India.

Holotype: Male; EAST MALAYSIA, Borneo, Sabah, Tambunan Distr., Crocker Range, 1550–1650 m a.s.l., near pass (road from Kota Kinabalu to Tambunan), Lithocarpus - Castananopsis, sifting decomposing wood, dead leaves and moss; 16.V.1987; leg. D. Burckhardt & I. Löbl [#27a].

Paratypes: 2 males, 3 females; collected together with the holotype.

Diagnosis: The new species is characterized by the unmodified carapace of males, which is untypical for the genus and previously known only from N. asocialis and N. chrysanthusi, as well as by the presence of two elongated pockets in the epigyne, similar to that of the Nepalense N. comata. Judging from the male palpal conformation, N. intuberosa sp. nov. is similar to two other new species described in here from the Mt Kinabalu, i.e., N. kinabalu sp. nov. and N. sabah sp. nov. From these two species N. intuberosa sp. nov. differs by the absence of a hump on the male carapace, by the shape of the palpal tibia, by details of the embolic division, as well as by the presence of two pockets divided by a relatively wide septum in the epigyne.

Etymology: The specific epithet is a Latin adjective referring to the absence of a hump on the male carapace, which is a characteristic feature for the genus Nasoona.

Description:

Male (paratype): Total length 1.65. Carapace 0.75 long, 0.65 wide, unmodified, pale brown, with grey radial stripes as shown in Figs 5–7; eyes normal. Chelicerae 0.35 long, unmodified.

Each metatarsus with a trichobothrium. TmI 0.61. Palp (Figs 42–46): Tibia relatively short, its retrolateral branch wide, with several very short spinules terminally, and with a black, pointed tubercle on its inner side. Prolateral branch well-sclerotized, stylet-shaped. Proximal part of paracymbium narrow, L-shaped; distal part wide, ending in a hook. Distal suprategular apophysis very short, flat, with a black, sharp tooth in middle, and with a transparent, narrow process terminally. Embolus long and thin, forming a loop, radix reduced.

Löbl [#12b].

Diagnosis: The species appears to be most similar to N. sabah sp. nov., and differs by the shorter retrolateral outgrowth of the male palpal tibia, by the shape of the paraconvector, as well as by the presence of a bipartite visor-like structure above the epigynal cavity.

Etymology: The specific epithet is a name in apposition referring to the “terra typica”, Mt Kinabalu on Borneo.

D. Burckhardt & I. Löbl [#34b].

Other material examined: Male holotype of Pronasoona sylvatica Millidge, 1995; Kinabalu N.P., Poring Hot Springs.

Diagnosis: The new species is characterized by the shape of the postocular elevation on the male carapace which looks like a transverse ridge similar to that in Pronasoona sylvatica, but P. sylvatica, has only one row of spines on the elevation, N. sabah sp. nov. has two rows of bent, stout spines. According to the male palp structure the new species appears most similar to N. kinabalu sp. nov. (see above). The epigyne of N. sabah sp. nov. resembles that of N. chrysanthusi, but differs by the shape of the translucent seminal ducts.

Etymology: The specific epithet is a name in apposition referring to the “terra typica”, the Sabah State of East Malaysia on Borneo Island.

Description:

Male (paratype from Silau-Silau Trail): Total length 2.02. Carapace 0.93 long, 0.70 wide, pale brown, with grey radial stripes and a narrow margin. A transverse postocular ridge slightly bent forward and bearing two rows of curved, stout spines. Spines of anterior row directed forward, those of posterior row directed backwards, as shown in Figs 10–13; eyes normal. Chelicerae 0.35 long, unmodified. Legs pale brown. Leg I 3.26 long (0.88+0.20+0.85+0.80+0.53), IV 3.23 long (0.90+0.22+0.83+0.80+0.48). Chaetotaxy: 2.2.1.1, length of spines about 1.5–2.5 diameters of leg segment. Each metatarsus with a trichobothrium. TmI 0.60. Palp (Figs 56–61): Retrolateral branch of palpal tibia relatively long and wide, with several very short spinules terminally and with a black rounded tubercle on its inner side. Prolateral branch strongly sclerotized, dagger-shaped. Paracymbium L-shaped, ending with a hook. Distal suprategular apophysis short, flat, narrow, with a black, sharp tooth in middle. Embolus long and thin, forming a loop, radix reduced. Main body of convector curved, its distal apophysis dark, narrow, serrate. Paraconvector large, complicated, with a long, claw-shaped distal process. Abdomen 1.28 long, 0.70 wide, dorsal pattern as shown in Fig. 10.

Female (paratype from Silau-Silau Trail): Total length 2.15. Carapace 0.95 long, 0.70 wide, unmodified. Chelicerae 0.43 long, unmodified. Legs pale brown. Leg I 3.41 long (0.95+0.25+0.88+0.83+0.50), IV 3.46 long (1.00+0.25+0.90+0.83+0.48). Chaetotaxy: 2.2.1.1, length of spines about 1.5–3 diameters of leg segment. Each metatarsus with a trichobothrium.

Distribution: Only known from Mt Kinabalu on Borneo, East Malaysia.

Holotype: Male; INDONESIA, northern Sulawesi, Kotamobagu, Matali Baru, road to Torosik, Mt Tongara, 600–900 m a.s.l.; 5.XII.1999; leg. A. Riedel.

Other material examined: Male holotype and 2 females paratypes of Nasoona silvestris Millidge, 1995 from Sumba Island, Indonesia.

Diagnosis: The new species appears most similar to the Neotropical N. coronata, known from San Esteban N.P., Venezuela. This similarity is seen the palpal structure, namely in the shape of the large, strongly sclerotized convector and paraconvector. Nasoona sulawesi sp. nov. is also somewhat similar to N. crucifera, which is widespread in the Oriental Region (World Spider Catalog, 2017) and to N. silvestris, described from Sumba, Indonesia (Millidge, 1995). Nasoona sulawesi sp. nov. is distinguished from the above-mentioned species by the shape of the strongly modified palpal tibia and by details of the palpal sclerites.

Etymology: The specific epithet is a name in apposition referring to the “terra typica”, Sulawesi Island.

Description:

Male (holotype): Total length 1.83. Carapace 0.85 long, 0.70 wide, greyish brown, with a postocular elevation bearing bent, stout spines as shown in Figs 14–16; occipital region of elevation with a small hollow bearing very short hairs as shown in Fig. 15; eyes normal.

Chaetotaxy: 2.2.1.1, length of spines about 1.5–2.5 diameters of leg segment. Each metatarsus with a trichobothrium. TmI 0.53. Palp (Figs 64–69): Tibia divided into four parts of different shapes. Dorsal branch of palpal tibia with several very short spinules terminally. Proximal part of paracymbium narrow, L-shaped; distal part wide, bearing several weak spines, ending with a hook. Distal suprategular apophysis short, flat, rounded distally, with a sharp black tooth in middle. Embolus long and thing, forming a loop; radix reduced. Main body of convector massive, black, distally divided by a narrow cleft into two parts, these serrate distally. Paraconvector large, complicated, with a long, claw-shaped distal process. Abdomen 1.01 long, 0.65 wide, dorsally dark grey, with a white, median stripe as shown in Fig. 14. Female. Unknown.

Distribution: Only known from the type locality in northern Sulawesi, Indonesia.

Remarks: This Nepalense species was hitherto known from males only (Tanasevitch, 1998). When re-examining material collected during Jochen Martens' expeditions to Nepal and kept at the SMF, the unknown females were found. The male of N. comata was described in detail earlier (see Tanasevitch, 1988), therefore I here only give photos of the male body (Fig. 22) and prosoma (Fig. 23). The first description of the female of N. comata is given below.

Material examined: All specimens in SMF: 1 male, 6 females; NEPAL, Taplejung Distr., Hellok in Tamur Valley, 2000 m a.s.l., forest remnant, bushes; 17.V.1988; leg. J. Martens & W.

Schawaller [#351]. – 5 females; Omje Kharka NW Yamputhin, natural mixed broadleaved forest, 2300–2500 m a.s.l.; 1.-6.V.1988; leg. J. Martens & W. Schawaller [#356]. – 2 females; pasture Lassetham NW of Yamputhin, 3300–3500 m a.s.l., mature Abies Rhododendron forest; 6.-9.V.1988; leg. J. Martens & W. Schawaller [# 59]. – 1 female; upper Simbua Khola, ascent to pasture Lassetham, 3000–3150 m a.s.l., mature mixed Tsuga-Rhododendron broadleaved forest; 15.V.1988; leg. J. Martens & W. Schawaller [#364]. – 1 male, 6 females; Hellok in Tamur Valley, 2000 m a.s.l., forest remnant, bushes; 17.V.1988; leg. J. Martens & W. Schawaller [#371]. – 3 females; Panchthar Distr., Paniporua, 2300 m a.s.l., mixed broadleaved forest; 16.-20.IV.1988; leg. J. Martens & W.

Description:

Female (specimen from Hellok): Total length 2.30. Carapace 1.15 long, 0.80 wide, unmodified, reddish brown, with a narrow, grey margin. Chelicerae 0.45 long. Legs pale brown. Leg I 4.33 long (1.25+0.30+1.13+1.00+0.65), IV 4.30 long (1.20+0.30+1.10+1.10+0.60). Chaetotaxy 2.2.1.1. Each metatarsus with a trichobothrium. Tm I 0.68. Abdomen 1.25 long, 0.85 wide, dorsal pattern as shown in Figs 25–26. Epigyne (Figs 24, 27) with elongated pockets divided with relatively wide septum. Seminal ducts wide, receptacles oval.

Taxonomic remarks: According to genitalia conformation, N. comata appears most similar to the Bornean N. intuberosa sp. nov. The male of N. comata can be easily distinguished from that of N. intuberosa sp. nov. by the presence of a hump on the male carapace bearing a group of bent, stout spines (see Figs 22–23), as well as by the shape of the palpal tibia. Females differ by more widely separated pockets of the epigyne in N. comata.

Distribution: The species has hitherto been known from 1650–2300 m a.s.l. in the Ilam, Panchithar and Taplejung districts in Nepal. The new records expand the known distribution of this species in Nepal, and its altitudinal range to 3500 m a.s.l.

Type material examined: NHML #bm.1995-7-25-12; female holotype of Nasoona locketi; Rakata, Krakatoa, Sept. 1984 (Latrobe Exped.). – NHML #bm.1995-7-2511; male paratype of Nasoona locketi; Rakata, Krakatoa, Sept. 1984. (Latrobe Exped.).

Remarks: The species was originally described from both sexes from Krakatoa Island, Indonesia (Millidge, 1995). As mentioned above, the untypical chaetotaxy in the male (1.1.1.1 instead of 2.2.1.1) is the result of an incorrect count of the number of spines caused by partial loss. The figures of the male palp given by the author for N. locketi (see Millidge, 1995: figs 27–29) do not accurately reflect its structure, therefore I give new schematic drawings of the male paratype here (see Figs 70–74). The “basal apophysis of the embolic division” of Millidge (1995: 45), which is marked in figs 24 and 28 as “A” [the same in fig. 23 for N. coronata], is indeed an apophysis of the convector.

Nasoona nigromaculata Gao, Fei & Xing, 1996: 29, figs 1–5.

Remarks Type material: The type material had been deposited at the Department of Cellular Biology, Norman Bethune University of Medical Sciences (Changchun, China), but according to Shou-Wang Lin is now lost (pers. comm.).

Taxonomic remarks: This species was originally described from specimens collected in the Anhui and Zhejiang provinces of China and placed in the genus Nasoona. Despite the poorly drawn genitals, it is quite obvious that the species actually belongs to Oedothorax. The transfer proposed here is also supported by the same chaetotaxy (2.2.1.1), by the presence of a trichobothrium on metatarsus IV, as well as by the similar conformation of genitals.
