Genus Solaenaulus Attems, 1940

Diagnosis.

A genus of Opisotretidae with 19 (♂) or 20 (♀) body segments. ♂ vertex without modifications. Metaterga with three regular, transverse rows of bacilliform setae. Frontolateral margin of midbody paraterga without shoulders. Ozopore usually lying very close to caudal margin of paratergite’s caudolateral corner (Figs 4C, D, F, 5B, G).

Gonopod telopodite elongate, subunciform, bipartite; basal process (p) on frontoventral face of femorite prominent, removed from femorite proper; distal part of telopodite usually beset with bacilliform ornamentations both over a prominent solenomere (sl) and an even more prominent exomere (ex); a small accessory seminal chamber present, but a hairy pulvillus absent (Figs 6A, C–F, 7).

Type species.

Opisotretus butteli Carl, 1922, by original designation of Attems (1940).

Remarks.

In addition to the type species, the genus currently contains only one known species: Solaenaulus birmanicus Carl, 1941 ( Golovatch et al. 2010), which, however, is sometimes treated as a variety of the type species ( Jeekel 2006).
