Earwigs (Dermaptera) of Socotra Island: checklist, distribution, and description of a new genus and four new species Author Kočárek, Petr text Acta Entomologica Musei Nationalis Pragae 2014 2014-12-30 54 1 21 journal article 10.5281/zenodo.5312352 0374-1036 5312352 2C4DD1B7-A32F-41FF-B866-3AC74B3083EC Guanchia sokotrana ( Burr, 1905 ) comb. nov. ( Figs 20–23 , 28 ) Anechura sokotrana Burr, 1905: 493 Type locality. Yemen , Socotra Island . Type material. Not studied.The deposition of type material is not stated in the original description of BURR (1905) . HAAS et al. (2004) suggested that the holotype could be deposited in The Natural History Museum, London.There is a specimen (male) labelled as Anechura fedchenkoi Saussure, 1874 (now Oreasiobia fedschenkoi (Saussure, 1874)) ; but this specimen is marked by an additional label stating ‘described as new / A. sokotrana / Burr inedit / Type MB’. Material examined. Wadi Mathif , N12°27′28.4″ , E 54°18′22.3″ , 20.vi.2009 , 3 ♀♀ , V . Hula lgt.

The sternal plates of this species have structure typical for the subfamily Forficulinae with a quadratic, as wide as long mesosternum ( Fig. 21 ). The shape of the mesosternum is the only diagnostic characteristic that subdivides Forficulinae and Anechurinae . Therefore, Anechura sokotrana must be moved to the subfamily Forficulinae , within which the species fits well with the generic diagnosis of the genus Guanchia Burr, 1911 , characterised by abbreviated, obliquely posteriorly truncate tegmina ( Fig. 20 ). Distribution. Yemen , Socotra Island ( Fig. 28 ). Most likely an endemic species.
