Genus Hybridolinus Schillhammer, 1998 Hybridolinus Schillhammer, 1998: 146; Schillhammer, 2000: 144 (key to species); Hayashi, 2000: 23 (notes on empodial setae); Herman, 2001: 2694 (world catalog); Smetana, 2004: 638 (catalog for Palaearctic region); Schillhammer, 2008: 242 (revised key to species). 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).
