Type species: Hybridolinus daliensis Schillhammer, 1998 , fixed by original designation. Diagnosis. The genus Hybridolinus can be easily distinguished from other genera in the subtribe Philonthina by the combination of the following character states: maxillary palpi long, with last segment rodlike and slightly longer than penultimate segment ( Fig. 2 A); labial palpi with 2nd segment very long, bearing four setae at base ( Fig. 2 B); pronotum densely punctate, narrowly impunctate along midline; superior line of pronotal hypomeron extended (from point where it bends ventrad) into slightly crenulate ridge that forms the additional “fake” lateral line ( Fig. 1 G); first four protarsal segments in both sexes distinctly dilated, with some modified pale setae ventrally; protibia apically with ctenidium consisting of one row of stout setae ( Fig. 2 C); abdomen with all tergites bearing only one basal line ( Fig. 1 H); basal line of sternite III extended apicad into acute process ( Fig. 1 I); paramere of aedeagus bilobed apically, underside of each lobe with a group of small and irregularly arranged sensory peg setae ( Figs. 6 F–I, 7B, E, H, L).
