Xyleborus cruralis Schedl, 1975b: 456.
Coptodryas cruralis (Schedl): Beaver, 1995a: 201.
Microperus cruralis (Schedl): Smith et al. 2020b: 287.
3.0−3.1 mm long (mean = 3.03 mm; n = 3); 2.5−2.82 times as long as wide. This species is distinguished by its large size; elytral disc broadly, deeply transversely impressed with a saddle-like depression from scutellum to declivital base; elytral declivity deeply sulcate, its margins lined by large tubercles on interstriae 1, 3−6; elytral base emarginated from sutural margin to interstria 4 to accommodate mycangial tuft, mycangial tuft setae long, very dense; and posterolateral costa absent.
