A new species of the genus Birdantis Stål, 1863 (Hemiptera: Fulgoridae), B. bhaskarai sp. nov. from Larat Island (Tanimbar), is described. Birdantis collaris (Walker, 1870) stat. rev. and B. trilineata (Schmidt, 1926) stat. rev. are reinstated as valid species, respectively from status of subspecies and as junior synonym of B. delibuta Stål, 1863. These four species, as well as the other one previously described from the Maluku Islands, B. decens Stål, 1863, are illustrated from their type specimens. An identification key, a distribution map, illustrations of habitus and details of male genitalia are provided. The synonymy between Myrilla Distant, 1888 and Birdantis is formally reinstated and all species formerly placed in the subgenus Birdantis (Myrilla) are transferred to Birdantis sensu stricto. Birdantis is transferred to the subfamily Aphaeninae Blanchard, 1847 and now contains eighteen species distributed in Maluku (five species), New Guinea and neighbouring islands (ten species) and Australia
(three species).
The concept of the jumping spider genus Pochytoides Berland & Millot, 1941 is reviewed, based on the examination of described and undescribed species. Pochytoides is elevated from the subgeneric to the generic rank and a short diagnosis and description of the genus are presented. Redescriptions or descriptions of all species are provided together with a key to the species. Two new combinations are proposed: Pochytoides perezi (Berland & Millot, 1941) comb. nov. and P. poissoni (Berland & Millot, 1941) comb. nov. (both from Pochyta). Pochyta remyi Berland & Millot, 1941 originally placed in the subgenus Pochytoides is excluded; new combination Thiratoscirtus remyi (Berland & Millot, 1941) comb. nov. is proposed for it (but its generic status is uncertain). Six new species are described: Pochytoides monticola sp. nov., P. obstipa sp. nov., P. lamottei sp. nov., P. patellaris sp. nov., P. securis sp. nov. and P. spiniger sp. nov. The genus has a West African distribution.
Siamopsis gen. nov., described here, belongs to a group of genera with the right valve overlapping the left valve in the subfamily Cypridopsinae Kaufmann, 1900 of the family Cyprididae Baird, 1845. The distinguishing characters of the new genus are in the morphology of its valves and soft parts. The postero-dorsal margin of the internal left valve is plate-like protruded. The morphology of this plate varies in different species, e.g., some species bear a tooth-like tubercle on the plate. The posterior margin of the right valve is recurved inwardly at ca mid-height, resulting in the occurrence of a lobe-like expansion that can clearly be seen in the dorsal and caudal views of the carapace. In addition, the other diagnostic soft part features of the new genus are the cylindrical caudal ramus, the presence of two t-setae on the female A2 penultimate segment, the very elongated terminal segment of the Mx1 palp, the morphology of the two large bristles (tooth bristles) of the Mx1 third endite (one smooth, one serrated) and the absence of d-seta on T1. In the present paper, five new species are described under this new genus: Siamopsis renateae gen. et sp. nov., S. suttajiti gen. et sp. nov., S. conspecta gen. et sp. nov., S. khoratensis gen. et sp. nov. and Siamopsis planitia gen. et sp. nov. A key to the species of Siamopsis gen. nov. is also provided.
Ten new species belonging to three new genera (Atlantisina gen. nov., Bathycyclopora gen. nov., Calvetopora gen. nov.) of umbonulomorph bryozoans from northeastern Atlantic seamounts, islands, and the continental slope are introduced. We furthermore erect the new family Atlantisinidae fam. nov. for these genera. Eight new species belong to the new genus Atlantisina: Atlantisina atlantis gen. et sp. nov. (type species), A. acantha gen. et sp. nov., A. gorringensis gen. et sp. nov., A. inarmata gen. et sp. nov., A. lionensis gen. et sp. nov., A. meteor gen. et sp. nov., A. seinensis gen. et sp. nov., and A. tricornis gen. et sp. nov. The genus Bathycyclopora gen. nov. is introduced for ?Phylactella vibraculata Calvet from the Azores, and also includes Bathycyclopora suroiti gen. et sp. nov. The type species of Calvetopora gen. nov. is Lepralia inflata Calvet from the Gulf of Cadiz; this genus also includes Calvetopora otapostasis gen. et sp. nov. and another species left in open nomenclature. Of the 13 species described herein, 11 occur on seamounts and islands, and nine species are endemic to a single seamount, island or station. The present results show that bryozoans provide striking examples of the function of seamounts as areas of endemism, most likely intrinsically linked to the low dispersal abilities of bryozoan larvae.
Twelve new species are assigned to the genus Otitoma Jousseaume, 1898 in the family Pseudomelatomidae Morrison, 1966 and herein described: O. hadra sp. nov., O. neocaledonica sp. nov., O. rubiginostoma sp. nov and O. tropispira sp. nov. from New Caledonia; O. boucheti sp. nov., O. nereidum sp. nov. and O. sororcula sp. nov. from the Fiji Islands; O. xantholineata sp. nov. from the Solomon to the Fiji Islands; O. crassivaricosa sp. nov. from Fiji to Hiva Oa Island (Marquesas Archipelago); O. philpoppei sp. nov. from the Philippines but also reported from the Fiji Islands; O. elegans sp. nov. from the Fiji Islands and O. philippinensis sp. nov. from the Philippines. New data on O. carnicolor (Hervier, 1896) are provided. Otitoma mitra (Kilburn, 1986), from Southern Mozambique, is here considered a synonym of O. cyclophora (Deshayes, 1863). Drillia batjanensis Schepman, 1913, previously assigned to the genus Maoritomella Powell, 1942 in the family Borsoniidae Bellardi, 1875, is here assigned to the genus Otitoma. Photographs of the holotype of Drillia batjanensis are provided for the first time. In addition, color photographs of the type specimens of the following species are provided: Drillia kwandangensis Schepman, 1913, D. timorensis Schepman, 1913 and Mitrellatoma mitra Kilburn, 1986.
Two new species of hangingflies, Terrobittacus rostratus sp. nov. and Terrobittacus angustus sp. nov., are described and illustrated from Yunnan, southwestern China, increasing the species number of Terrobittacus Tan & Hua, 2009 to six. Terrobittacus rostratus sp. nov. differs from its congeners by wings devoid of markings and epandrial appendages slightly longer than half the length of the gonocoxites. Terrobittacus angustus sp. nov. can be recognized by wing markings along R5 distally. A key to species of the genus is updated to include the two new species.
The spider diversity of the family Anyphaenidae in premontane, low evergreen montane and cloud forest from the Chocó region of Ecuador is examined. A total of 287 adult specimens were collected and 19 morphospecies were identified based on male specimens. Thirteen new species are described and one new genus is proposed. Five new species are described in the genus Katissa Brescovit, 1997: Katissa kurusiki sp. nov., K. puyu sp. nov., K. tamya sp. nov., K. yaya sp. nov. and K. guyasamini sp. nov. The new genus Shuyushka gen. nov. is proposed and includes three species: Shuyushka achachay gen. et sp. nov., S. moscai gen. et sp. nov. and S. wachi gen. et sp. nov. Finally, five species are described in the genus Patrera Simon, 1903: P. hatunkiru sp. nov., P. philipi sp. nov., P. suni sp. nov., P. shida sp. nov. and P. witsu sp. nov. New records are provided for Patrera fulvastra Simon, 1903 and Josa nigrifrons Simon, 1897.
The salticid genera Bristowia Reimoser, 1934, Habrocestum Simon, 1876 and Macaroeris Wunderlich 1992 are reported from Sri Lanka for the first time. One new species of Bristowia, B. gandhii sp. nov. (♂♀), and three new species of Habrocestum, H. hantaneensis sp. nov. (♂♀), H. kodigalaensis sp. nov. (♂♀) and H. ohiyaensis sp. nov. (♂), are described and diagnosed. The male of Macaroeris nidicolens Walckenaer, 1802 is redescribed and illustrated, based on new material from Sri Lanka.
Harpactea dufouri (Thorell, 1873) was collected in the Gavarres protected natural area in Catalonia, Spain. The specimens were compared with specimens from Mallorca, Balearic Islands,
and found to be conspecific. The female of the species is described here for the first time. The new finding proves that Harpactea dufouri occurs outside the Balearic Islands. The species, however, may be endemic to Catalonia.
