      Eine neue Gattung aus West Malaysia, sowie Analysen zur Unterfamile Selencosmiinae Simon 1889

      • A new tarantula genus, Psednocnemis, from West Malaysia (Araneae: Theraphosidae), with cladistic analyses and biogeography of Selenocosmiinae Simon 1889 RICK C. WEST, STEVEN C. NUNN & STEPHEN HOGG

      Abstract

      The selenocosmiine genus Psednocnemis gen. nov. is described from the Sundaland region of South-east Asia. The type
      species Psednocnemis davidgohi sp. nov., which the male was incorrectly identified as Coremiocnemis hoggi West &
      Nunn 2010, is herein described. Cladistic analyses of 46 morphological characters and 39 exemplar taxa from 12 genera
      were done. The genera analysed were: Reichlingia Rudloff 2001; ingroup: Chilobrachys Karsch 1891; Coremiocnemis
      Simon 1892; Haplocosmia Schmidt & von Wirth 1996; Lyrognathus Pocock 1895; Orphnaecus Simon 1892; Phlogiellus
      Pocock 1897; Poecilotheria Simon 1885; Psednocnemis gen. nov.; Selenobrachys Schmidt 1999; Selenocosmia Ausserer
      1871 (in part: Sundaland fauna only); Yamia Kishida 1920. The results presented Psednocnemis gen. nov. as monophyletic
      based on presence of a distal embolic spiral curl in males and presence of a distodorsal spiniform brush on the retrolateral
      surfaces of coxa IV, as well as the reduction in density of hair type 4, located along the proximoventral abdomen of both
      sexes. Two new tribes are described: Chilobrachini trib. nov. and Phlogiellini trib. nov., based upon basal nodes with strongest
      branch support that best reflected natural groups. Selenocosmiini Simon 1889 and Poecilotheriini Simon 1889 are
      revised and redescribed. Yamia Kishida 1920 is placed into junior synonymy of Phlogiellus (syn. nov.); Chilocosmia
      Schmidt & von Wirth 1992 and Selenobrachys Schmidt 1999 are placed into junior synonymy of Orphnaecus (syn. nov.);
      Selenocosmia xinping Zhu & Zhang 2008 is transferred to Phlogiellus, making the new combination Phlogiellus xinping
      (Zhu & Zhang 2008 ) comb. nov.; Selenocosmia dichromata (Schmidt & von Wirth 1992) is transferred to Orphnaecus,
      making the new combination Orphnaecus dichromata (Schmit & von Wirth 1992) comb. nov.; Coremiocnemis brachyramosa
      West & Nunn 2010, Coremiocnemis gnathospina West & Nunn 2010, Coremiocnemis jeremyhuffi West & Nunn
      2010 and Selenocosmia imbellis (Simon 1891) are transferred to Psednocnemis gen. et comb. nov. Poecilotherinae
      (Schmidt 1995) is no longer considered a valid subfamily and is replaced into Selenocosmiinae as the tribe Poecilotheriini.
      Chilocosmia barensteinerae Schmidt et al. 2010 is considered a Selenocosmiinae species incertae sedis. Ischnocolella
      senffti Strand 1907 is considered a nomen dubium. All other genera examined were retrieved as monophyletic in the first
      cladistic analyses exclusive to Selenocosmiinae genera (Australo-Papuan selenocosmiines are outside the scope of this
      work and are not considered). Biogeography of all Selenocosmiinae is discussed; the group is a potential model North
      Gondwanan taxon. A key to Psednocnemis species is provided.

      Die Änderungen betreffen die Spinnenhalter nun wie folgt,
      links die alte Artbezeichnung, rechts die neue Artbezeichnung:

      Selenocosmia dichromata = Orphnaecus dichromata
      Selenobrachys philippinus = Orphnaecus philippinus (Danke @Stefan Feiler)
      Coremiocnemis brachyramosa = Psednocnemis brachyramosa
      Coremiocnemis gnathospina = Psednocnemis gnathospina
      Coremiocnemis jeremyhuffi = Psednocnemis jeremyhuffi
      Selenocosmia imbellis = Psednocnemis imbellis




      Sobald ich das Paper habe, werde ich oder jemand anders der schneller ist :) , die Liste mit den zu ändernden Namen aktualisieren

      Danke und Gruss

      Tag
      In der letzten Zeile von Abstract, wird "is a potential model North Gondwanan taxon" erwähnt. Ist damit Gondwana gemeint, das sich im Mesozoikum (251 - 65 Mio.) von Pangaea (Paläozoikum 545 - 251 Mio.) löste? Falls dem so ist, wie und in welcher Form soll das ein Modell eines Taxons sein?
