On the taxonomic placement of four African Phoneyusa species (Araneae, Theraphosidae, Eumenophorinae)

Richard C Gallon, Ingo Wendt ,2015

Phoneyusa elephantiasis Berland, 1917 is illustrated, redescribed and, along with Phoneyusa celerierae Smith, 1990 and Phoneyusa efuliensis Smith, 1990, transferred to the genus Hysterocrates Simon, 1892. Type material of Hysterocrates gigas Pocock, 1897 and topotypes of Phoneyusa lesserti Dresco, 1973 are illustrated for comparison. Phoneyusa nigroventris (Marx, 1893) is treated as nomen dubium.

Ami, a new Theraphosid genus from Central and South America, with the description of six new species (Araneae: Mygalomorphae)

Fernando Pérez-Miles, Ray Gabriel, Laura Tavares Miglio, Alexandre Bonaldo, Richard C Gallon, Juan Jacobo Jimenez, Rogério Bertani ,2008

A new genus Ami Pérez-Miles is proposed for six new species: A. caxiuana Pérez-Miles, Miglio & Bonaldo, from Caxiuanã National Forest, Pará, Brasil, the type species; A. yupanquii Pérez-Miles, Gabriel & Gallon, from the area of Puyo, Equador; A. bladesi Pérez-Miles, Gabriel & Gallon, from Isla Colón, Panamá; A. pijaos Jimenez & Bertani, from Ibagué, Tolima, Colombia; A. amazonica Jimenez & Bertani, from Leticia, Amazonas, Colombia; and A. weinmanni Pérez-Miles, from La Azulita, Apure, Venezuela. Avicularia obscura (Ausserer 1875) is transferred to Ami and re-diagnosed. Diagnostic characters of Ami are the modification of Type I urticating hairs, with unusually longer area b, and one or two subconical processes on retrolateral face of male palpal tibiae. Females of Ami differ further from those of other theraphosid genera by their highly characteristic spermathecae: paired ventral receptacles attached to an almost discrete, semicircular, sclerotized back-plate.

A revision of the spider genera Chaetopelma Ausserer 1871 and Nesiergus Simon 1903 (Araneae, Theraphosidae, Ischnocolinae)

José Paulo Leite Guadanucci, Richard C Gallon ,2008

Chaetopelma Ausserer 1871 and Nesiergus Simon 1903 are revised. Cratorrhagus Simon 1891 is considered a junior synonym of Chaetopelma. Cratorrhagus tetramerus (Simon 1873) and the female of Cratorrhagus concolor (Simon 1873) are conspecific with C. olivaceum (C. L. Koch 1841). Ischnocolus gracilis Ausserer 1871, Ischnocolus syriacus Ausserer 1871, Chaetopelma shabati Hassan 1950 and Ischnocolus jerusalemensis Smith 1990 are also treated here as junior synonyms of C. olivaceum. Chaetopelma adenense Simon 1890 is proposed as a junior synonym of Ischnocolus jickelii L. Koch 1875. Chaetopelma gardineri Hirst 1911 is transferred to Nesiergus. Hence, Chaetopelma comprises three valid species: C. olivaceum (C. L. Koch 1841); C. karlamani Vollmer 1997; C. concolor (Simon 1873) n. comb. from the Middle East and northeastern Africa. Nesiergus, which appears endemic to the Seychelles archipelago, now comprises three valid species: N. gardineri (Hirst 1911) n. comb.; N. halophilus Benoit 1978; N. insulanus Simon 1903.

On a new genus and species of theraphosid spider from Serpent Island, Mauritius (Araneae, Theraphosidae, Eumenophorinae)

Richard C Gallon ,2005

A new genus and species of theraphosid, Mascaraneus remoras, is described from Serpent Island, Mauritius. The new species, although eumenophorine. lacks stridulatory setae, but plesiomorphically retains divided metatarsal scopulae on leg IV and distal clavate trichobothria on the tarsi. It is the first theraphosid spider recorded from the Mascarene Islands. Its biogeography and taxonomy are discussed.

Revision of the African genera Pterinochilus and Eucratoscelus (Araneae, Theraphosidae, Harpactirinae) with description of two new genera.

Richard C Gallon ,2002

The African theraphosid genera Pterinochilus Pocock, 1897 and Eucratoscelus Pocock, 1898 are revised, keyed, and their species distributions mapped. The subfamily Harpactirinae is redefined and its genera keyed. The follow- ing new synonyms and transfers are proposed: Brachionopus Pocock, 1897 is transferred to the Barychelidae; Pterino- chilus chordatus (Gerstäcker, 1873) is removed from the synonymy of P. constrictus (Gerstäcker, 1873); Pterinochilus widenmanni Strand, 1906, P. raptor Strand, 1906, P. affinis Tullgren, 1910, P. sjostedti Tullgren, 1910, P. carnivorus Strand, 1917, P. brunellii Caporiacco, 1940 and Coelo- genium raveni Smith, 1990=P. chordatus; Idiothele pluri- dentata Hewitt, 1919 and Eucratoscelus tenuitibialis Schmidt & Gelling, 2000=P. lugardi Pocock, 1900; P. elevatus (Karsch, 1878) is removed from the synonymy of P. con- strictus; P. elevatus nomen oblitum, P. mamillatus Strand, 1906 and P. hindei Hirst, 1907=P. murinus Pocock, 1897 nomen protectum; P. mutus Strand, 1920=P. simoni Berland, 1917; P. constrictus is transferred to Eucratoscelus, n. comb.; E. longiceps Pocock, 1898 and P. spinifer Pocock, 1898=E. constrictus (Gerstäcker, 1873); Augacephalus, gen. n. is established for P. breyeri Hewitt, 1919 and P. junodi Simon, 1904; Idiothele Hewitt, 1919 is removed from the synonymy of Pterinochilus; P. crassispinus Purcell, 1902= I. nigrofulva (Pocock, 1898); Trichognatha, gen. n. is estab- lished for P. schonlandi Pocock, 1900. The males of Augacephalus breyeri (Hewitt, 1919), A. junodi (Simon, 1904) and Eucratoscelus pachypus Schmidt & von Wirth, 1990 are described for the first time, as is the female of Trichognatha schonlandi.
