Figs 6-14 , 15-18 , 19-20 Type genus. Prateus LeConte, 1862. Description. Body length: 1.5-6.0 mm, stout to elongate, glabrous or setose. Most species are unicolored, fuscous to piceous, but a few species are patterned. Head : Eyes round to ovoid, at most feebly notched anteriorly by epistomal canthus. Antennae usually reaching the middle of the pronotum, sometimes extending just past the base of the pronotum; antennomeres obconical to moniliform with last three to five forming a weak to strong club. Thorax : Pronotum shape variable, usually quadrate to rectangular. Lateral margin complete, smooth to dentate. Procoxae clearly separated by prosternal process. Mesocoxal cavity laterally closed by meeting of lateral arms of meso- and metaventrite (Fig. 2 ). Elytra usually confusedly punctured, rarely with well-defined striae. Metathoracic wings usually well developed, but reduced or absent in some species. Legs slender, not fossorial. Penultimate tarsomeres lobed or cupuliform. Abdomen : Intersegmental membranes visible between sternites V-VII, abdominal hinging tenebrionoid. Defensive glands absent. Ovipositor slender, with three to four clearly separated coxite lobes, terminal coxite digitate, gonostyli apical or subapical. Figures 6-14.

Scale bars: 0.5 mm ( 7, 8 ); 1 mm ( 9, 12, 13 ); images lacking scale bars were produced by Otto Merkl and sizes of specimens were not recorded before he passed. Diagnosis. Prateini is distinguished from Goniaderini and Lupropini by having the mesocoxal cavity closed (i.e., laterally closed by meeting of meso- and metaventrite) and absence of abdominal defensive glands. In Lagriinae , this character combination is only shared with Cossyphini Latreille, 1802. These two tribes can easily be distinguished from each other by the general habitus; all species of Cossyphini have prominent pronotal and elytral flanges, and the pronotal flange covers the head. In Prateini , the pronotum never covers the head. Cossyphini also has medial hinging between abdominal sternites V-VII (i.e., tentyrioid hinging) and intersegmental membranes are not visible, while Prateini has lateral hinging between abdominal sternite V-VII (i.e., tenebrionoid hinging) and intersegmental membranes are visible.
