Baalzebub acutum sp. nov. is the second species recorded from Brazil, the first for Brazilian caves, bringing the total number of species in the genus to seven in the world.     

On the spider genus Arboricaria with the description of a new species (Araneae,Gnaphosidae)

The spider genus Arboricaria Bosmans, 2000 is redefined and an updated diagnosis given. The differences between Arboricaria and Micaria Westring, 1851 are discussed in detail. A key to all five species of the genus is provided. One new species, Arboricaria zonsteini sp. n. (♂♀), is described based on specimens from Kyrgyzstan and Azerbaijan. One new synonym is proposed: Arboricaria koeni Bosmans in Bosmans & Blick, 2000, syn. n. is assigned to Arboricaria sociabilis Kulczyński in Chyzer & Kulczyński, 1897. Data on the distribution of Arboricaria in Russia and adjacent countries are presented with references to the papers on local spider faunas.     

The genus Mesadenella (Orchidaceae) in Colombia with description of two new species

A review of the catfish genus Pterocryptis (Siluridae) in Vietnam, with the description of two new species

Of the silurid catfish genus Pterocryptis in Vietnam, a total of four species are recognized as valid, of which Pterocryptis crenula and P. verecunda are described here as new. The type locality of P. cochinchinensis is restricted to central Vietnam, and the species is redescribed from topotypic material. Pterocryptis crenula (from northeastern Vietnam) can be differentiated from its congeners in having visibly confluent anal and caudal fins while P. verecunda (from Cat Ba Island in northeastern Vietnam) can be differentiated from its congeners in having the genital papilla concealed behind the anus. Notes on the identity of other nominal Pterocryptis species are also provided.

The millipede genus Caucasodesmus Golovatch, 1985, with the description of a new species from the Crimea, Ukraine (Polydesmida, Diplopoda, Trichopolydesmidae)

The hitherto monotypic genus Caucasodesmus is new to the Ukrainian list due to the discovery of Caucasodesmus tauricussp. n. in a cave in the Crimea. The new species is easily distinguished from Caucasodesmus inexpectatus Golovatch, 1985, the type, and only other, known species of this genus, in the abundantly setose collum and following metaterga, and more elaborate gonopods. The status of Caucasodesmus, which shows in the superfamily Trichopolydesmoidea where it definitely belongs such evident generic-level apomorphies as the absence of bacilliform sensilla on antennomeres 5 and 7, of a cannula on the gonocoxite, and of a seminal groove on a biramous gononod telopodite (apparently, both latter characters are functionally correlated to each other), is refined by formally reassigning it to the family Trichopolydesmidae.     

Taxonomic notes on the genus Syndiamesa Kieffer (Diptera: Chironomidae) from Japan, with description of a new species

The Japanese species of the genus Syndiamesa are revised. A new species, Syndiamesa longipilosa sp. nov., from Honshu, Japan is described from male and female material. The male of Syndiamesa mira (Makarchenko) from Japan is redescribed and figured. Syndiamesa chuzemagna Sasa is synonymized with Syndiamesa yosiii Tokunaga. Syndiamesa bicolor Tokunaga is transferred to the genus Sympotthastia. A key to males of Japanese Syndiamesa is provided.     

Spiders of the genus Lachesana and a new storenoid genus from Israel (Araneae: Zodariidae)

Zodariid spiders of two genera in Israel are revised. The genus Lachesana is represented by two species. Only one male of these was ever depicted while the females of both and their hitherto unknown retreats were never described. Pax gen. nov. has been erected to accommodate five species, some of which have formerly been placed in Slorena, Selamia or Habronestes . Diagnostic characters of the West Mediterranean Selamia and the Australian Habronestes are newly illustrated. No drawings of Pax libani and P. islamita were ever published; the male of the latter is described here for the first time. Pax palmonii sp. nov. and P. engediensis sp. nov. are described and affinities of all taxa are discussed. Illustrations, records of distribution and keys to the species are provided.     

Notes on Pauropoda (Myriapoda) from USA, with descriptions of two new species

Two new species of Pauropoda are described from USA, Kionopauropus alyeskaensissp. n. (Pauropodidae), and Eurypauropus arcuatussp. n. (Eurypauropodidae). The genus Kionopauropus is reported from the Western Hemisphere for the first time.     

A new species of Cuacuba (Araneae,Theridiosomatidae) from Brazilian caves

ABSTRACT

A new species of the spider genus Cuacuba from Brazil, C. ribeira sp. nov. is described and illustrated based on eighty-six specimens collected from caves in the Vale do Ribeira region, in the states of São Paulo and Paraná. This species is recognized by the hook-shaped median apophysis on the male palp, and females by having invaginations on the sides of the median posterior edge of the epigynal plate. Cuacuba ribeira sp. nov. is the third species recorded for the genus, and like the other two, also comes from Brazilian caves.
