The new Southeast Asian genus Cambonilla gen. nov. (Zodariidae, Araneae): 'bis repetita placent'
(2019)
The new genus Cambonilla Jocqué gen. nov. is described on the base of two species, each known from both sexes. A cladistic analysis based on morphology, showed that the new genus is the sister-group of Heliconilla Dankittipakul, Jocqué & Singtripop, 2012 with which it shares the granulated carapace with branched setae and the marbled ventral abdominal pattern, but differs by the abdominal, tubular sclerotized protrusion around the pedicel in males and the absence of posterior ventral abdominal spines in the female. The type species Cambonilla securicula Jocqué gen. et sp. nov. was found in rainforest along the Mekong River in Cambodia and Laos. The second species Cambonilla symphonia Jocqué & Henrard gen. et sp. nov., provided with conspicuous femoral stridulating organs, was recorded from the same localities but in Cambodia only. An illustrated key to the genera of tropical Asia is presented.
A large white species of wolf spider, Ocyale ghost Jocque M. & Jocqué R. sp. nov., is described from a white sandy beach of an inland freshwater lake in the northwest of Madagascar. The first photos of a living specimen of the genus Ocyale are provided together with some observations on the biology of the newly described species. An updated and illustrated key to the Afrotropical species of Ocyale is included here.
Two new species of Phyxelididae are described from southern Africa: Xevioso cepfi sp. nov. (♂♀), from mountains in the Niassa Province of northern Mozambique, and X. megcummingae sp. nov. (♂♀), from urban Harare, northern Zimbabwe and the Viphya Mts in Malawi. They represent the northernmost localities of the genus. An identification key, partially adapted for the new species, is presented. The biogeographical importance of the mountain areas on both sides of the northern part of Lake Malawi is discussed.
Three new species of Pachygnatha, P. bispiralis sp. nov., P. intermedia sp. nov. and P. ventricosa sp. nov., are described from forest areas in western Burundi. The presence of P. procincta Bosmans & Bosselaers, 1994 in Burundi confirms its very wide distribution spanning most of Africa.
Pachygnatha appears to be an important element of the afromontane spider fauna.
The recently described family Chummidae, now the sister clade of Macrobuninae, so far only known from two South African species, is extended with seven new species, six from the southern part of South Africa and one from Lesotho: Chumma bicolor sp. nov. (♀), C. foliata sp. nov. (♂♀), C. interfluvialis sp. nov. (♂♀), C. lesotho sp. nov. (♀), C. striata sp. nov. (♂♀), C. subridens sp. nov. (♂♀) and C. tsitsikamma sp. nov. ♂. A key to the species is provided. Although Chumma is part of a clade containing the Macrobuninae, it is argued that the family name Chummidae should remain valid.
Tapinesthis inermis Simon, 1882, the only species in the genus, is widely distributed in western Europe. This redescription provides the first information on the ultrastructure of the species using SEM. The morphology of the spinnerets, tarsal claws and tarsal organs, and the internal structure of the female genitalia and the male palp are described and illustrated in detail. The combination of these structures is very similar to those encountered in some dysderoid spiders and supports the basal placement of Tapinesthis among Oonopinae. The phylogenetic relationships of the species are discussed. The only female among the three syntypes is designated as the lectotype.
Cteniogaster, a new genus of small ground spiders is described from Kenya and Tanzania. It encompasses seven new species, three of which are known from both sexes: C. toxarchus sp. nov., the type species, C. conviva sp. nov. and C. hexomma sp. nov. Three species are known from females only: C. lampropus sp. nov., C. sangarawe sp. nov. and C. taxorchis sp. nov. and one only from males: C. nana sp. nov. The new genus can be recognised by the presence of a posterior ventral abdominal f eld of strong setae and anterior lateral spinnerets with enlarged piriform gland spigots in males. A cladistic analysis attributes the genus to Liocranidae, Cybaeodinae. The results of the analysis performed do not produce an unequivocal autapomorphy for Liocranidae, but provide a combination of non-homoplasious character changes that offers significant potential for recognising genera as Liocranidae. Moreover, robust apomorphies are determined within Liocranidae for the subfamilies Liocraninae and Cybaeodinae. Based on these fi ndings Toxoniella Warui & Jocqué, 2002 is transferred from Gallieniellidae to Liocranidae, Cybaeodinae. Jacaena Thorell, 1897, Plynnon Deeleman-Reinhold, 2001 and Teutamus Thorell, 1890 are transferred to Corinnidae, Phrurolithinae and Montebello Hogg, 1914 to Gnaphosidae. Itatsina Kishida, 1930 is synonymised with Prochora Simon, 1886.
A revision of the genus Cicynethus Simon, 1910 (Araneae, Zodariidae), a tale of colour patterns
(2018)
The genus Cicynethus Simon, 1910 is revised. Apart from the type species C. peringueyi Simon, 1893, only known from a juvenile, it contains five species, all of which are here described or redescribed based on adults: C. acer sp. nov. (♂♀), C. decoratus (Lawrence, 1952) comb. nov (♂), C. floriumfontis Jocqué, 1991 (♂♀), C. mossambicus sp. nov. (♂♀) and C. subtropicalis (Lawrence, 1952) comb. nov. (♂♀). The species are characterized by the genitalia, but also by the colour pattern. The distribution of the genus is extended to northern Mozambique. Cicynethus hongfuchui is transferred to Storenomorpha hongfuchui (Barrion, Barrion-Dupo & Heong, 2013) comb. nov. Cicynethus acanthopus Simon, 1910 is considered a species incertae sedis. A key to the species is provided.
Ballomma, a new Afrotropical genus in the Cryptothelinae (Araneae, Zodariidae): eyes on the run
(2015)
Ballomma gen. nov. is described in the zodariid subfamily Cryptothelinae. It is characterized by the pairs of adjacent anterior median eyes and anterior lateral eyes and triangular palpal tarsus in the female, the concave tegulum with thin embolus in the male. Apart from the type species B. erasmus gen. et sp. nov. (♂♀), the genus contains B. haddadi gen. et sp. nov. (♂♀), B. neethlingi gen. et sp. nov. (♂♀), and B. legala gen. et sp. nov. (♀). A key to the species is provided. The restricted distribution of the genus is discussed.
