Homotoma chlamydodoraHollis & Bromfield, 1989 (Homotomidae) and Pauropsylla tatricheaHollis, 1984 (Triozidae) are two poorly known psyllid species that develop on Ficus vallis-choudae. Based on material collected within the framework of biodiversity studies of psyllids (Hemiptera: Psylloidea) associated with Ficus spp. (Moraceae) in Cameroon, the taxonomy of the two psyllid species is revised and information on the biology is provided. In particular the previously unknown immatures of both species and the male of P. tatrichea are described and illustrated here. A tubercular process on the mesocoxa of P. tatrichea, a putative autapomorphy of PauropsyllaRübsaamen, 1899 is described here for the first time. Both species are polyvoltine with overlapping generations. Immatures of H. chlamydodora develop under the stipules whereas those of P. tatrichea induce pit galls on the leaves. Both species appear to be restricted to Ficus vallis-choudae, at least locally.

Five new species are described, Plusiocampa (Didymocampa) cvijici Sendra & Antić, sp. nov., Plusiocampa (Plusiocampa) atom Sendra & Antić, sp. nov., Plusiocampa (Stygiocampa) barethae Sendra & Rađa, sp. nov., Plusiocampa (Stygiocampa) dulcici Sendra & Rađa, sp. nov. and Plusiocampa (Venetocampa) pirnati Sendra & Borko, sp. nov. This brings the number of cave-adapted species of campodeids known from the Dinarides, Eastern Alps, Balkan System and Rodope Massif to 28 (one species in the genus Campodea and 27 in Plusiocampa). Among Plusiocampa, four out of five subgenera are present (Pentachaetocampa is not present in the region studied): Didymocampa (one species), Plusiocampa s. str. (15 species), Stygiocampa (eight species) and Venetocampa (three species), whereby Stygiocampa and Venetocampa are endemic to the studied region. These results reveal the importance of the Dinarides karst region as a centre of diversification for campodeids and for cave animals in general. A monophyletic subgroup, consisting of Stygiocampa, Venetocampa and Plusiocampa s. str. and characterized by the absence of medial posterior thoracic macrosetae, presumably colonized the Dinaric plate during the middle of the Cenozoic and occurs in that area since then.

Phalotris Cope, 1862 is a fossorial dipsadid snake genus that encompasses 15 species, distributed mainly in open areas from Northeastern Brazil to Southern Argentina. Some of its species are known from small series, and there is little to no knowledge on their morphological variation and species delimitations. In this work, we analyze the taxonomic status of Phalotris cerradensisSilveira, 2020, a recently described species known from a single specimen, and provide evidence for its synonymy with Phalotris concolorFerrarezzi, 1993.

Nous avons échantillonné des fourmis dans la forêt de Yakouren en combinant trois méthodes: pots barber, chasse à vue et appâts alimentaires. Vingt-sept (27) taxons ont été répertoriés appartenant aux sous-familles suivantes: Myrmicinae, Formicinae et Dolichoderinae. Camponotus alii, Pheidole pallidula et Crematogaster auberti levithorax sont les espèces les plus abondantes. Le calcul de différents estimateurs de richesse (Chao 1, Jackknife 1 et ICE) montrent qu'il y a toujours une possibilité de rencontrer de nouvelles espèces en augmentant l'effort d'échantillonnage. La composition des peuplements de fourmis dans le massif de Yakouren révèle une faible dégradation du milieu par rapport à des relevés réalisés dans les années 1960. Le milieu souffre des actions anthropiques, dont des incendies, que subit la région depuis plusieurs décennies. Les statuts taxonomiques de Camponotus lateralis purius et d'Aphaenogaster sardoa ujhelyii sont discutés.

The Brazilian fauna of DiptychophoraZeller, 1866 (Lepidoptera, Pyralidae sensu lato, Crambinae) is reviewed. Consisting of three species based on the literature (D. diasticta Gaskin, 1986, D. kuhlweiniiZeller, 1866 and D. subazanalisBłeszyński, 1967), this fauna is augmented with three new species (Diptychophora galvani sp. n. from Mato Grosso and Minas Gerais, D. planaltina sp. n. from the Federal District, and D. ardalia sp. n. from Bahia), that are described and illustrated. The female of D. diasticta is also described and illustrated for the first time. A partial CO1 barcode sequence is provided for D. diasticta.

Le Scinque officinal ou Poisson de sable Scincus scincus (Linnaeus, 1758) (Scincidae: Squamata) est un lézard qui a une aptitude à se mouvoir dans les sables du désert particulièrement remarquable. Il a fait l'objet d'études anatomo-fonctionnelles en lien avec sa locomotion originale, ainsi que récemment d'études sur sa valeur nutritionnelle comme source de protéines animales, mais à ce jour, aucun travail sur la biométrie ou sur le dimorphisme sexuel de cette espèce n'a été publié. Cette étude de la morphométrie externe de l'animal repose sur 100 individus adultes (50 mâles et 50 femelles) de la sous-espèce Scincus scincus scincus (Linnaeus, 1758) récupérés dans la région de El Oued Souf (Algérie) et vise à caractériser le dimorphisme sexuel de l'espèce. En plus du poids vif des individus, 11 paramètres linéaires ont été mesurés par animal et 3 indices de forme ont été calculés. Pour chaque variable, une valeur seuil permettant de discriminer au mieux les mâles des femelles est proposée. Le modèle linéaire généralisé multivarié le plus discriminant intègre CT (le périmètre thoracique), T (la longueur de la tête) et LmP (la longueur du membre pelvien). Cependant, la mesure T, considérée seule, discrimine avec un faible taux d'erreur.

Two new species, Acalles romani and Echinodera philippei, are described from Algeria and Morocco and are distinguished from related species. They are incorporated in the current key to the North African Acalles and Echinodera species. In addition to morphological characters, first molecular results (DNA barcoding) are presented. The new taxa are included in phylogram of the most closely related species from Northwest Africa, Spain, Italy and the Iberian Peninsula.

A new genus, Himalafurca gen. nov., with two new species, Himalafurca martensi sp. nov., the type species, and H. schawalleri sp. nov., are described from the Nepal Himalayas. The genus resembles KetambeaMillidge & Russell-Smith, 1992 and some other genera of unclear subfamily affiliation, but strongly differs by a few important structural features in the palp. All records of Collinsia japonica (Oi, 1964) from Nepal actually refer to Halorates crassipalpis (Caporiacco, 1935) comb. nov., here transferred from Collinsia. New localities for 21 species known from Nepal are given and six additional species are reported for the fauna of Nepal for the first time: Agyneta pakistanica Tanasevitch, 2011, Bathyphantes paracymbialis Tanasevitch, 2014a, Gnathonarium gibberumOi, 1960, Nematogmus dentimanusSimon, 1886, Tiso aestivus (L. Koch, 1872) and T. indianus Tanasevitch, 2011. All mentioned species, except the last one, are also new to the fauna of the Himalayas. Taking into account the new data, the spider fauna of Nepal is currently known to include at least 107 linyphiid species, 90% of which presently can be considered as Himalayan endemics.

Acerentomon italicumNosek, 1969 is the most abundant Protura species in Italy. Two groups of populations characterized by the different position of a pore on tergite VII were analyzed. Specimens from Austria and from the Italian provinces of Brescia and Bolzano (Lombardy and Alto Adige, respectively) possess a postero-sub-medial pore (psm); in specimens from Trento (Trentino), Veneto, Friuli-Venezia Giulia and Liguria the pore is in an antero-sub-lateral (asl) position. An integrative approach was applied to assess other characters distinguishing these populations. The lengths of body, head, foretarsus, claw of anterior leg, foretarsal sensilla a and b were measured; in addition some ratios were calculated: TR (length of foretarsus/length of its claw), BS (distance of sensillum t1 from base of foretarsus/distance of t1 from foretarsus tip), length of a/foretarsus length, length of b/foretarsus length and length of a/length of b. A geometric morphometric analysis was performed on the position of setae on tergite VII, selecting as landmarks the bases of setae A1, A2, A3, P1, P1a, P2, P2a and P3. Nucleotide sequences COI-5P and 28S-D2-D3 of both groups were compared. Significant differences in the foretarsus and anterior claw length, in the arrangement of setae on tergite VII and in the barcode sequences COI-5P between the “psm and asl populations” are shown to exist. Based on the results obtained, the two groups are different, but there is not enough support to differentiate them at the species level.

The Achilia cosmoptera species group sensu Jeannel (1962) of the species-rich genus Achilia Reitter, 1890 is revised. Of the twelve taxa placed so far in this informal group, four species – A. andinaFranz, 1996, A. maiopensisFranz, 1996, A. pseudangularisFranz, 1996, and A. quinteroiFranz, 1996 – belong to different genera and will be treated in forthcoming papers, and one name is placed in synonymy – A. piceaRaffray, 1904 = A. elfridaeRaffray, 1904syn. nov. The remaining seven species are redescribed, and three new species fitting the concept of the A. cosmoptera group are described – A. covidian. sp., A. pandemican. sp., and A. quarantenan. sp. The lectotypes of A. cosmoptera (Blanchard, 1851), A. blanchardiRaffray, 1904, A. elfridaeRaffray, 1904, A. bifronsJeannel, 1962, and A. nahuelbutaeFranz, 1996 are designated, and the new synonymies A. nahuelbutaeFranz, 1996 = A. angularisJeannel, 1962syn. nov., and A. caneloiFranz, 1996 = A. temporalisJeannel, 1962syn. nov. are also established. For all these species of the A. cosmoptera group their distribution is detailed and mapped, and habitat/collecting data are summarized.

Cyphochilus brancuccii n. sp., C. hlai n. sp., C. nanzhao n. sp., C. keithi n. sp., C nguyendui n. sp., C. nguyenvanvinhi n. sp., C. phamthinhiae n. sp., and C. zianii n. sp. are described based on the study of about 570 specimens. These species are largely distributed in Laos and Vietnam, marginally in Myanmar, Thailand, and South China. Previously they were confused with C. ventriglaberBrenske, 1903. The parameres and distribution of the nine species here treated are illustrated.

Records are given for 15 Scaphisomatini species captured by V-flight intercept traps in Arizona. Baeocera hamata Löbl & Stephan, B. nana Casey and Toxidium gammaroides LeConte are recorded for the first time from Arizona, B. arizonensis sp. nov., B. obscura sp. nov. B. vintercepta sp. nov. and Scaphisoma declivum sp. nov. are described as new. Scaphisoma dakotanum Fall is synonymized with S. desertorum Casey. The aedeagi of Scaphisoma desertorum Casey, S. rufulum LeConte, and S. rubens Casey are illustrated for the first time. A key to the Arizona species of Scaphisoma Leach is provided. A new iteration of the V-flight intercept trap is described and the diversity of Arizona Scaphisomatini is discussed.

On the basis of two recently collected specimens from Meghalaya state in north-eastern India, we report the occurrence of the monotypic vespertilionid genus Eudiscopus in the Indian Subcontinent. This taxon has so far been known only from a few localities in Southeast Asia. Our records also constitute a westward range extension of E. denticulus by about 1000 km into eastern South Asia. We provide comparative mensural data of several museum specimens of E. denticulus from Southeast Asia. Additionally, the echolocation call and wing characteristics of this species from Meghalaya are also described. The higher call frequency and lower wing loading and aspect ratio of the Indian E. denticulus indicate adaptation to cluttered environment, corroborating its guild assignment as edge space aerial forager. Molecular comparisons of the mitochondrial cytochrome b gene sequence with samples from Vietnam revealed no genetic variation, despite large geographic distances separating the samples. Phylogenetic reconstructions confirm that Eudiscopus is a basal Myotinae, but its position relative to Submyotodon and Myotis is still uncertain.

A new species of the genus MaripanthusMaddison, 2020, M. gloria Caleb, sp. nov. (♂♀) is diagnosed and described from the Karnataka State of India. A map showing the distributional records of all known congeners is provided.

A new species of the genus Vietnamophryne is described from Vu Quang National Park in North Vietnam based on molecular phylogenetic and morphological analyses. The new species is morphologically distinct from congeners and can be easily distinguished from all other members of the genus Vietnamophryne by (1) body size males (n=4) 14.12-14.91 mm; females (n=9) 15.15-17.33 mm; (2) dorsal skin shagreened with small flat pustules loosely scattered on back in males, mostly smooth, slightly shagreened posteriorly, lacking enlarged tubercles in females; (3) belly color ivory-lemon to lemon-yellow with weak dark-brown marbling in males, bright lemon-yellow with weak dark-brown marbling in females; (4) tympanum relatively faint, comparatively small, rounded, 5.4-6.0% of SVL in males, 4.8-6.2% of SVL in females; (5) ratio snout length to eye length 119-128% in males, 100-130 % in females; (6) ratio head width to head length 117-124% in males, 110-131% in females; and (7) ratio first finger to second finger 43-49% in males, 44-50% in females. In the phylogenetic analysis the new species revealed to be sister to V. inexpectata, with 4.3-4.6% divergence in the 16SrRNA gene. So far, the new species is only known from the evergreen tropical forests of Vu Quang National Park at an elevation of 966 m a.s.l. This is the third species of Vietnamophryne reported from Vietnam.

A new pseudoscorpion species of the genus Garypus, G. schwendingeri, is described from a seashore habitat in southern Thailand.
