Monophyly of Dimorphaphorura

The genus Dimorphaphorura was recovered as nonmonophyletic in both the equal- and implied-weighting parsimony analyses. Although all but one species of Dimorphaphorura are clustered together in clade C, the support for this resolution is low (Figs. 1 and 2).

The genus was recovered by Weiner (1996) and recently revised by Weiner and Kaprus’ (2014) who provided diagnostic characteristics of the genus. The authors defined it on the base of organization of the furcal area: furcal remnant in a form of finely granulated area with three rows of setae behind and lack of dental setae. The generic status of Dimorphaphorura was recently questioned by Shvejonkova and Potapov (2011). As mentioned above, all characters used to define genus are variable and scattered in different combination across genera.
