Maschwitzia Kistner 1989: 301 (original description).

Type species.

Maschwitzia ulrichi Kistner, 1989.

Diagnosis.

This genus is closely allied to Witteia in general appearance, especially pronotal shape, but may easily be distinguished from it by having a generalized labrum, not strongly sclerotized and without projections; the simple mandibles, their inner edges not emarginate at middle; the straight lateral projections of the labial apodeme; the much smaller eyes; the shorter antennae; and the shorter legs.

Comments.

Kistner et al. (2008) transferred Trachydonia aenictophila Kistner, 1997 and Trachydonia dichthadiaphila Kistner, 2003 to Maschwitzia . However, they are apparently not members of Maschwitzia , nor even closely related in view of the absence of the autapomorphies of Wroughtonilla Wasmann, 1899 and its allied genera (see Discussion). Though the genus Zyras Stephens, 1835 is heterogeneous, apparently non-monophyletic and not well defined yet, they can be placed in Zyras (s.lat.) by sharing the general diagnostic features of the genus (e.g., Fenyes 1920) and excluded from Maschwitzia , as follows:

Zyras (s. lat.) aenictophila (Kistner in Kistner et al. 1997),comb. n.

Zyras (s. lat.) dichthadiaphila (Kistner in Kistner et al. 2003), comb. n.

Trachydonia Bernhauer 1928 has been placed as a subgenus of Zyras , but Kistner et al. (2003) raised it to generic status. At least Zyras aenictophila and Zyras dichthadiaphila are not members of Trachydonia . They are also not members of the subgenus Zyras . The genus Zyras should be subdivided into several genera based on a phylogenetic analysis, and then adequate systematic affiliation of these two species may be found.

The following four species are known in Maschwitzia .
