Diagnosis. Body
covered in long fine hairs.
Head:
Rostrum slightly longer and narrower than head, very weakly narrowed toward apex; scrobes gradually descending in strong arc, ending near lower margin of eye not greatly expanded; epistoma in roughly the same plain as dorsal surface of the rostrum. Eyes weakly convex.
Thorax:
Elytra striae usually absent very weak at most, scales on dorsal surface not imbricate.
Legs:
uniform in color, front tibiae expanded at apex, hind tibae greatly expanded, claws free.
Median lobe:
Endophallus with subapical lobe on interior surface.
Description. Head:
Rostrum slightly longer and narrower than head, very weakly narrowed toward apex; alae very feebly dilated; surface of head and rostrum convex, without transverse sulcus. Eyes small, slightly convex, oval, slightly wider than long. Antennae with scape slender basally, abruptly clavate, reaching middle of eyes in repose; funicle slender, seven segmented, basal segment as long as next two combined, outer segments shorter, moniliform, seventh slightly wider than long, oval close to club; terminal segment elongate, rather narrow, pointed, finely pubescent; remainder coarsely and sparsely setose. Scrobes beginning on sides at apex, gradually descending in strong arc, ending near lower margin of eye, deep and narrow. Mentum large, flat, not deeply placed, filling entire gular cavity, wider than long, broadly rounded at apex. Genae with small and weak mandibular emargination.
Thorax
: Pronotum with distinctly laterally expanding margins. Scutellum visible from above. Elytra convex, intervals not distinct. Legs short and robust; front tibiae expanded at apex; covered in scales, hind tibia greatly expanded at apex.
Hind
coxae very widely separated, at sides of body, small. Tarsi spinose ventrally, with third segment distinctly wider than second; claw segment as long as remainder combined; basal segment scarcely longer than second. Claws long, free.
Abdomen:
first suture arcuate in middle; second segment slightly longer than next two combined.
Median lobe:
curved, weakly in some species; narrowing in distal quarter, to point at apex. Endophallus with subapical lobe on interior surface, transfer apparatus weakly or strongly scleritized.
