Orphnus (Cerhomalus) absconditus Petrovitz, 1971: 3.
Differential diagnosis
Cerhomalus absconditus can be easily separated from congeners by having the apices of the parameres rounded (in apical view), without semi-circular excavations (Fig. 2G, J) and without keels or fossae on ventral side (Fig. 2K), and the base of elytra with somewhat tile-shaped punctures (Fig. 2 A–B).
