Xenopygus Bernhauer View in CoL

Xenopygus Bernhauer, 1906: 196 View in CoL [species included: X. analis (Erichson, 1840) View in CoL , X. bicolor (Laporte, 1835) View in CoL ]; full taxonomic history in Caron et al. 2016.

Leptodiastemus Bernhauer, 1934: 215 [described as subgenus of Dysanellus View in CoL , species included: Dysanellus (L.) excellens Bernhauer, 1934 View in CoL ]; type species Dysanellus (L.) excellens Bernhauer, 1934 View in CoL ; fixed by monotypy. New synonymy.

Type species: Xenopygus analis (Erichson, 1840) ; Blackwelder 1943: 451.

Diagnosis. Xenopygus can be distinguished from all other Xanthopygina based on the combination of the following characters: antennomeres 6–10 transverse (in contrast to several species of superficially similar Oligotergus that have antennomeres 6–10 subquadrate or longer than wide); labial palpomere 3 truncate and not securiform; head narrow (much wider in the related genus Xanthopygus ); nuchal ridge developed (absent in some Xanthopygina genera); neck with punctures and micropunctures (punctation absent in most Xanthopygina genera); postcoxal process present (absent in Oligotergus ); abdominal terga III–IV or III–V with arch-like carina (absent in some closely related Xanthopygina genera).
