Wasmannellus Bernhauer, 1920

TYPE SPECIES: Wasmannellus tristis Bernhauer, 1920 .

COMMENTS: Members of this genus share the following character states: (1) superior line of pronotal hypomeron moderately separate from inferior line anteriorly, becoming obsolete near anterior angle of pronotum; (2) bases of first four visible abdominal tergites markedly transversely impressed, with punctation different from that on rest of tergites; (3) hind tibia without spines on dorsolateral face.

Further character states include: apical segment of maxillary palpus asetose, almost as wide apically as at middle; apical segment of labial palpus setose, apex expanded to about 1.5 times width of base, slightly obliquely securiform; lateral end of nuchal ridge distinctly removed from nuchal constriction, directed distinctly posteriad of transverse postgenal ridge; pronotal hypomeron very broad at middle, deflected portion of pronotal disc visible only from anterior edge of coxal insertion in ventral view; prothoracic epimeron absent; medial margin of sternacostal ridge extended anteriad into sharp, finlike carina; serial setae on mesosternum inserted along edge of elevated, irregular ridge parallel to margins; mesosternal intercoxal process with margins converging acutely, acute at apex, distinctly margined throughout; margins of anterior metasternal projection converge rectangularly, very broadly rounded at apex.

The genus at present contains only two species, but there is at least one additional undescribed species in the eastern part of the Palearctic region (mainland China).
