Type species. Philonthus glenoides Schubert, 1908 ; fixed by monotypy. Diagnosis. The genus Craspedomerus can be easily distinguished from the other genera in the subtribe Philonthina by the combination of the following character states: maxillary palpi long, with 4th segment cylindrical and distinctly longer than penultimate segment ( Fig. 1 E); labial palpi long, with 3th segment slightly longer than 2nd segment ( Fig. 1 F); antennae moderately long, basal three segments polished, bearing only sparse strong setae, 3rd segment much longer than 2nd, the following segments gradually decreasing in length, but all longer than wide; first four segments of front tarsus in both sexes at least slightly dilated, with some modified pale setae ventrally ( Fig. 1 F); pronotum densely and finely punctate, narrowly impunctate along midline; superior line of pronotal hypomeron deflexed under third anterior margin of pronotum and extended (from point where it bends ventrad) into slightly crenulate ridge that forms the additional “fake” lateral line ( Fig. 1 G); abdomen with tergites III–V bearing two basal lines ( Fig. 2 H); basal line of sternite III arcuately extended posteriad in middle ( Fig. 1 J); sternite VIII of male with moderately wide, obtusely triangular medio-apical emargination; sternite IX of male genital segment with basal portion distinctly asymmetrical; aedeagus with median lobe distinctly exceeding paramere, evenly narrowed into subacute apex; paramere bifurcate apically, Y-shaped ( Fig. 2 F), underside of each branch with group of rather small, irregularly arranged sensory peg setae ( Figs. 12 A–I).
