A new species of Phrixotrichus (Araneae, Theraphosidae) from southwestern Argentina and new distributional data for P. vulpinus
Nelson Ferretti ,2015A new species of Phrixotrichus Simon, 1889, P. pucara sp. nov., is described and illustrated based on a male from Pucará river, Neuquén province, Argentina. Male can be distinguished from all other species of the genus by the presence of a long strong spine on inner face of prolateral branch of tibial apophysis; also, it differs from P. scrofa (Molina, 1788) and P. vulpinus (Karsch, 1880) by a serrated prolateral keel of the male palpal bulb. Male resembles P. jara Perafán & Pérez-Miles, 2014 but can be distinguished by the uniform color on dorsal cephalothorax and by the palpal organ morphology being wider on the bulb base and embolus shorter and thicker, with the tip of embolus not so directed retrolaterally and prolateral keel bearing a serrated edge with three teeth. Additionally, P. vulpinus is reported for the first time for Argentina along with new distributional data.
Revalidation of Dolichothele Mello-Leitão and notes on Hapalotremus Simon (Araneae, Mygalomorphae, Theraphosidae)
Hapalotremus exilis (Mello-Leitão, 1923) and Hapalotremus muticus (Mello-Leitão, 1923), previously considered as nomina dubia are here revalidated through the examination of the holotypes. Dolichothele Mello-Leitão, 1923 is revalidated and their type species, Dolichothele exilis Mello-Leitão, 1923 is restored. Goniodontium Mello-Leitão, 1923 and Oligoxystre Vellard, 1924 are considered junior synonyms of Dolichothele. Hapalotremus muticus and Oligoxystre caatinga Guadanucci, 2007 are considered junior synonyms of D. exilis. All species of Oligoxystre are transferred to Dolichothele. Cyclothoracoides Strand, 1929, currently a junior synonym of Hapalotremus Simon, 1903, is here considered a junior synonym of Homoeomma Ausserer, 1871.http://www.tandfonline.com/doi/abs/10.1080/01650521.2015.1103553
Nelson Ferretti ,2015Three unknown species of Euathlus Ausserer 1875 (Araneae: Theraphosidae) are recognized and formally described. Euathlus diamante Ferretti sp. nov., E. sagei Ferretti sp. nov., and E. tenebrarum Ferretti sp. nov. are described from the Mendoza and Neuquén provinces of western Argentina. The cladistic analysis showed Euathlus as monophyletic supported by the following synapomorphies: i) male tibial apophysis with fused branches bases; ii) presence of a ventral spine on retrolateral branch of male tibial apophysis; iii) sternum longer than wide. According to this cladistics analysis, a tree topology of (Homoeomma uruguayense (Mello-Leitão 1946) (Plesiopelma longisternale (Schiapelli & Gerschman 1942) (Grammostola anthracina (C.L. Koch 1842) (Phrixotrichus scrofa (Molina 1788) (E. tenebrarum sp. nov. (E. truculentus L. Koch 1875, E. sagei sp. nov. ((E. parvulus (Pocock 1903) (E. condorito Perafán & Pérez-Miles 2014, E. manicata (Simon 1892), E. atacama Perafán & Pérez-Miles 2014)) (E. antai Perafán & Pérez-Miles 2014, E. diamante sp. nov.)))))))) is reported.
Revision of the genus Phormingochilus with the description of three new species from Sulawesi and Sarawak and notes on the placement of the genera Cyriopagopus, Lampropelma and Omothymus
Andrew Smith, Michael A Jacobi ,2015Three new arboreal theraphosid spiders of the genus Phormingochilus Pocock, 1895 are here described from Sulawesi and Sarawak, Borneo: Phormingochilus carpenteri sp. nov., P. kirki sp. nov., and P. pennellhewletti sp. nov. The genus has been revised and historical species redescribed. The authors have also discussed the placement of the Ornithoctoninae genera Cyriopagopus Simon, 1887, Lampropelma Simon, 1892 and Omothymus Thorell, 1891 and, after an examination of the type material, concluded that Cyriopagopus is a senior synonym of the genus Haplopelma Simon, 1892 and that the genus Omothymus needs to be restored to house the arboreal Malaysian mainland species schioedtei (Thorell, 1891) and thorelli (Simon, 1901), which were formerly assigned to the genus Cyriopagopus but have now been restored to their original placement. We have also concluded, on examination of the type material that the female of Lampropelma violaceopes Abraham, 1924 from Southern Malaysia should be removed from the genus Lampropelma (whose distribution at present, we believe to be limited to Lampropelma nigerrimum from Sangihe (Sangir) Island) and placed in the genus Omothymus, whereas the male, from Penang, is deemed to be a misidentified specimen of Cyriopagopus (Omothymus) schioedtei.
Revised generic placement of Brachypelma embrithes (Chamberlin & Ivie, 1936) and Brachypelma angustum Valerio, 1980, with definition of the taxonomic features for identification of female Sericopelma Ausserer, 1875 (Araneae, Theraphosidae)
Ray Gabriel, Stuart J. Longhorn ,2015The tarantula genus Sericopelma was originally defined based on male specimens, most notably lacking tibial spurs on leg I. Early female specimens were unrecognised as Sericopelma, and typically placed in Eurypelma – a dumping ground for problem specimens. The first females were only later recognised, but authors failed to adequately define female Sericopelma. Here, the holotypes of the Southern-most alleged Brachypelma species, B. embrithes (Chamberlin & Ivie, 1936) and B. angustum Valerio, 1980 were examined, and finding both to possess defining characteristics of Sericopelma were transferred. The taxonomic attributes to define Sericopelma relative to Brachypelma and select other Neotropical genera are discussed, especially for females. As important diagnostic characters for Sericopelma, the single (unilobar) spermathecae swollen at the apex forming a P-shaped cross-section, metatarsus IV with trace scopula, femur IV with a dense retrolateral pad of plumose hair, plus other attributes. Some past confusion in these characters are clarified and Sericopelma relative to Brachypelma and Megaphobema mesomelas are discussed. Finally recommendations are given about these taxonomic changes for CITES regulations.

The Neotropical genus Cyriocosmus Simon, 1903 and new species from Peru, Brazil and Venezuela (Araneae: Theraphosidae: Theraphosinae)
Radan Kaderka ,2015Cyriocosmus peruvianus sp. nov., C. itayensis sp. nov., C. aueri sp. nov., C. giganteus sp. nov. from Peru, Loreto region, C. hoeferi sp. nov. from Brazil, C. williamlamari sp. nov. and C. nicholausgordoni sp. nov. from Venezuela are described, illustrated, diagnosed and both sexes, if known, keyed. New Peruvian species can be distinguished from all congeners, except C. bertae Pérez-Miles, 1998 and C. pribiki Pérez-Miles and Weinmann, 2009, by the uniformly coloured carapace and abdomen without stripes and by the short paraembolic apophysis in male palpal bulb. The female of Cyriocosmus ritae Pérez-Miles, 1998 is described for the first time from a known Peruvian population near Iquitos.
On the taxonomic placement of four African Phoneyusa species (Araneae, Theraphosidae, Eumenophorinae)
Richard C Gallon, Ingo Wendt ,2015Phoneyusa 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.
Two new species of Bonnetina tarantulas (Theraphosidae: Theraphosinae) from Mexico: contributions to morphological nomenclature and molecular characterization of types
David Ortiz, Oscar F. Francke ,2015Two new species of tarantulas from Mexico are described and illustrated: Bonnetina tenuiverpis and Bonnetina juxtantricola, from the states of Mexico and Guerrero, respectively. Male palpal bulbs, tibial apophyses and spermatheca are among the most taxonomically informative characters. Male bulb microstructure is revealed from scanning electron microscopy; both new and homologous structures to other Theraphosinae genera are identified and described. Nomenclatural changes for male tibial apophyses are also proposed. The holotype male and allotype female of one of the species are molecularly characterized and matched from CO1 partial sequence.
Ein Weibchen von Lampropelma nigerrimum arboricola ssp. n. aus Borneo (Araneae: Theraphosidae: Ornithoctoninae)
Gunter Schmidt, R Barensteiner ,2015Lampropelma nigerrimum arborieola is a subspecies of Lampropelma nigerrimum living in Borneo. It is closely related to L. nigerrimum nigerrimum SIMON, 1892, the type species of the genus, living on Sang ir (or Sangihe) Island. An adult female could be studied. It differs from the type species in the relative size of the eyes, the spination of the legs and the scopula of the fourth metatarsus. The PLE are much smaller than the ALE, aillegs are spinose and scopula of metatarsus IV is present apically in the centre of the segment only. According to Jean-Michel VERDEZ the males of both subspecies are different. In L. nigerrimum nigerrimum the herringbone pattern on the opisthosoma is distinct and the tarsi are not orange, in L. nigerrimum arborieola the herringbone pattern on the opisthosoma is absent and the tarsi are weakly orange. The new subspecies is dealt under the name L. sp. "Borneo blael(' or Selenoeosmia borneoensis. Both of them are nomina nuda. It is said to live arboreously.

New information on Annandaliella travancorica Hirst, 1909 from Western Ghats of India (Araneae: Theraphosidae)
Sunil K Jose, M. T. Prasanth ,2015Male of Annandaliella travancorica Hirst, 1909 (Fam: Theraphosidae) is recorded from Kozhikode, India. Detailed morphological characters and illustrations of body and copulatory organs of the species are presented. Information on new localities are also mentioned.
Radan Kaderka ,2014Ami armihuariensis sp. nov. from Cuzco region, Peru is described, diagnosed and figured. Males of Ami armihuariensis sp. nov. differ from all other congeners, except A. pijaos, by the presence of only one retrolateral process on male palpal tibia, from A. pijaos by the granulation in tegular area of male palpal bulb. Additionally, photographs of A. yupanquii spermatheca are for the first time presented in order to emphasize the characteristic shape of spermathecae in this genus.
Revised taxonomic position of Psalmopoeus rufus Petrunkevitch, 1925 and Psalmopoeus affinis Strand, 1907 (Aranaeae: Theraphosidae)
Ray Gabriel ,2014Psalmopoeus rufus Petrunkevitch, 1925 is relegated to a synonym of Psalmopoeus pulcher Petrunkevitch, 1925. Psalmopoeus affinis Strand, 1907 is regarded as Nomen dubium.
Bumba, a replacement name for Maraca Pérez-Miles, 2005 and Bumba lennoni, a new tarantula species from western Amazonia (Araneae, Theraphosidae, Theraphosinae)
The first Hapalotremus Simon, 1903 (Araneae: Theraphosidae) from Argentina: description and natural history of Hapalotremus martinorum sp. nov
A new species of Hapalotremus Simon, 1903 from northern Argentina is described and illustrated. Hapalotremus martinorum sp. nov. differs from all other congeners by the colour pattern of live specimens. Males differ in the male palpal bulb morphology, with thickened and less curved embolus having a blunt subapical keel and less-developed apical keel. Females differ in the shape of the spermathecae, with the lateral bases more pronounced than the superiors and the upper edge more rounded. Specimens were captured inhabiting short burrows or crevices under stones in high cloud forests. Hapalotremus cyclothorax (Mello-Leitão 1923) is a junior synonym of Homoeomma montanum (Mello-Leitão, 1923), Hapalotremus scintillans (Mello-Leitão 1929) is a junior synonym of Pachistopelma rufonigrum Pocock, 1901, Hapalotremus exilis (Mello-Leitão 1923) and Hapalotremus muticus (Mello-Leitão 1923) are considered species inquirenda.http://zoobank.org/urn:lsid:zoobank.org:pub:1758F6FD-8883-445D-A757-0AC7E120DCF6
