  • new genus Kochiana; & Kochiana brunnipes new. comb.

    Hi all,

    there is a new genus: Kochiana

    Avicularia brunnipes has been moved to Kochiana brunnipes
    • FUKUSHIMA, C. S., R. H. NAGAHAMA & R. BERTANI (200: The identity of Mygale brunnipes C.L. Koch 1842 (Araneae, Theraphosidae), with a redescription of the species and the description of a new genus. The Journal of Arachnology 36: 402-410.

      Abstract:
      We describe Kochiana new genus to accommodate a small Brazilian theraphosine species described originally as
      Mygale brunnipes by Koch (1842), resulting in Kochiana brunnipes new combination. Recently, specimens were rediscovered
      in northeastern Brazilian Atlantic rainforest. A preliminary cladistic analysis using equal weights parsimony and implied
      weights, was carried out to examine its phylogenetic placement. Kochiana new genus was monophyletic in all trees
      regardless of weighting scheme or concavity used. There is preliminary evidence for Kochiana new genus monophyly and
      weak evidence for its placement as sister group of Plesiopelma. Kochiana new genus can be characterized by the presence of
      a hornshaped spermatheca in females and males with a palpal bulb having prolateral accessory keels and a well developed
      medial crest on the embolus apex.


    all the best,
    Martin
