diagnosis
Diagnosis. Antennal scapus in both sexes straight, as long as or slightly longer than funiculus, slightly dilated at apex, as broad as pedicel; females in some species with a fine tuft of scant long setae, otherwise with few short setae; funiculus (including pedicel) 5 - segmented; club on anterior face usually with one procurved suture close to apex, smooth and suture-free on posterior face. Elytra with scale-like or hair-like setae, a single row on each interstriae; strial setae minute or absent. Procoxae contiguous. Protibiae twisted, with 2 or 3, (rarely 4 or 5) lateral and apical denticles. Metatibiae with three lateral and apical denticles. Ventral setae simple, unifid. Proventriculus with a cluster of 3 – 10 strong crop spines attached to a tubercular base in front of the apical plate; apical teeth transverse or lightly curved, finely dentate; masticatory teeth smooth, closing teeth free, not compact. Male genitalia with a long flagellum, sometimes straight and broad, sometimes very long and coiled; tegmen difficult to assess, either reduced or absent, apophyses more than twice as long as aedeagal body; spiculum gastrale about as long as or slightly shorter than aedeagus (Figs 56 – 57).
discussion
Remarks. Gender feminine as outlined by Alonso Zarazaga and Lyal (2009). In the key to species, be aware that morphological differences can be subtle and specimens which are badly preserved or otherwise slightly deviant from type material should be tried in alternative directions in the key and compared to photos (Figs 2 – 53). Also note that sexual dimorphism varies from no dimorphism at all, to moderate differences in the apical width of the scapus and the density and length of setae on its dorsal side, and in the presence of impressed frons. Only a single holotype or very few specimens from the type series are available for study in some species, possibly only of one sex; additional variation could therefore appear in new samples.
