F44E1F7C291BC237986D52C2398F5883.taxon	diagnosis	Diagnosis. The genus Lasinus can be readily separated from the other genera of the Pselaphodes complex (Hlavac 2003) by a combination of the following characters: 1) head with well-defined setose frontal and vertexal foveae, 2) maxillary palpi small, with palpomeres III-IV symmetrical, neither roundly expanded nor projecting laterally, 3) antennal club three-segmented, with antennomeres VIII-IX often modified in males, 4) pronotal lateral and median foveae well-defined, 5) pronotum lacking antebasal sulcus connecting foveae, 6) pronotal longitudinal sulcus present, well- to weakly-defined, 7) tarsal segments II linear, segments III inserted at the apex of the II, 8) basal carinae on the first visible tergite (IV) present, short, 9) median setose metaventral fovea absent, 10) metaventral horny processes reduced to short, stout protuberances.	en	Bekchiev, Rostislav, Hlavac, Peter, Nomura, Shuhei (2013): A taxonomic revision of Tyrini of the Oriental region.
