ABSTRACT
Pronotum subquadrate to slightly elongate, to distinctly transverse, widest posterior of midlength in most taxa; pronotal disc evenly convex or with various grooves and depressions, laterally explanate in some genera (especially Melandryini); disc with posterolateral pits in most taxa; lateral margins of pronotal disc
without, or with partial to distinct carina; posterior edge of pronotum tightly appressed against, or lying loosely over, base of elytra; prosternum in front of coxae shrunken and very short (especially in some Serropalpini) to relatively long; suture between prosternum and propleuron carinate and somewhat excavated in some genera; prosternal process short and indistinct; procoxae subglobular to elongate; procoxal cavities open or closed; protrochantin exposed in some genera; legs moderately to distinctly elongate, sexually dimorphic in some groups (especially Osphya); front legs generally smaller than middle, and especially hind legs; femora subcylindrical to distinctly flattened, parallelsided to slightly enlarged at midlength; tibiae thin to moderately wide, parallel to slightly widened distally; dorsal surface in some groups (notably Serropalpini) with ornamentation consisting of transverse combs or longitudinal carinae; tibial spurs distinct (especially in Serropalpini and Orchesiini), relatively straight (males of Enchodes with ventral protibial spur distinctly bent), either subequal or distinctly unequal in length; tarsi 5-5-4 in both sexes; tarsomeres narrow, simple (e.g., Orchesiini) or widened, with penultimate tarsomere expanded ventrally; tarsal claws narrow, simple, except for Osphya, with distinct basal tooth.
