Misgolas montanus (Rainbow & Pulleine, 1918)

Wishart, Graham, 2011, Trapdoor Spiders of the Genus Misgolas (Mygalomorphae: Idiopidae) in the Illawarra and South Coast Regions of New South Wales, Australia, Records of the Australian Museum 63 (1), pp. 33-51 : 49

Misgolas montanus (Rainbow & Pulleine, 1918)

Arbanitis montanus Rainbow & Pulleine, 1918 , pp. 12, 81–169, figs 12–24; Main, 1977, placed in synonymy with Dyarcyops fuscipes (Rainbow, 1914) ; Main, 1985 a, Dyarcyops fuscipes placed in synonymy with Misgolas rapax .

The species status of Arbanitis montanus Rainbow & Pulleine, 1918 was revised and removed from synonymy with M. rapax by Wishart & Rowell (2008) on expressed grounds of differences in male palpal morphology. Wishart & Rowell, 2008 explicitly removed M. montanus from the synonymy of M. rapax but this was not accepted by Platnick (2010). To satisfy the minimal requirement the species is figured and diagnosed. Figures of the palp and bulb of A. montanus male syntype are provided here ( Fig. 13A–C ) to enable comparison with M. rapax ( Fig. 4A–C ). Differences in the number and size of folds along edge of retrolateral embolic flange and positions of apophysis on embolus is evidence of considerable weight demonstrating different species are being dealt with.
