Description
Head: Eyes strongly protruding, conspicuously emarginate at antennal insertion; interocular space larger than one eye width; gular sutures subparallel to divergent, gular process varying in width, from narrow to broad; antennal length interspecifically variable and sometimes sexually dimorphic (longer in males), A2 shorter than A3, A3-A8 more or less filiform, A10 broader than long, A11 sub-ovate, apical half pinched, mostly without club, sometimes terminal three antennomeres forming a loose club.
Thorax: Proepimeron medium-sized, more or less acute; anterior mesosternal process present, with a subtriangular sulcus in the middle (Fig. 7); metendosternite with normal furcal stalk length, furcal arms broad, apically dilated, stalk base very slightly to deeply emarginate (Fig. 20). Elytra subparallel, sometimes broadest behind middle, apices rounded (most species), strongly dehiscent (Xenorthrius prolongatus and Xenorthrius furcalis), or dentate (Xenorthrius truncatus and Xenorthrius scordalus); elytral punctation arranged into ten striae.
Legs: Mostly relatively short; tarsal pulvillar formula 4-4-4, tibial spur formula 1-2-2; tibiae with or without longitudinal carinae; claws with pronounced basal denticle (Fig. 10).
