Carphontes Bates, 1881

Carphontes Bates, 1881: 171; Monné, 2005: 31 (cat.).

Type-species. Carphontes posticalis Bates, 1881 (monotypy).

Redescription. Form small, rounded. Head moderately prominent; eyes coarsely faceted; superior lobes large, separated by the width of a lobe; lower lobes 4 times taller than genae below. Antennal tubercles not elevated; antennae filiform, 11-segmented, without hairs on the ventral surface, scape elongate; segment 3 ¼ longer than scape; segment 4 about as long as segment 3, segments 5–10 gradually decreasing in length; segment 11 as long as segment 10.

Prothorax transverse, armed with a prominent lateral tubercle situated in the posterior third. Pronotum without calli or tubercles. Prosternal process narrow, width approximately equal to 1/3 of the procoxa; mesosternal process as wide as the mesocoxa. Elytra with sides subparallel to apical ¼, then evenly rounded to suture, length approximately equal to 1.5 times humeral width; without setae, lateral or dorsal carinae, or centro-basal crista; apices narrowly rounded. Anterior coxae rounded and prominent; femora subclavate. First segment of posterior tarsi shorter than two following segments combined.

Remarks. The genus is characterized by the body without setae; prothorax with lateral tubercles in the basal third; pronotum without tubercles; elytra shortened, about 1.5 times humeral width, without longitudinal carinae or median crista near base; narrow prosternal process; mesosternal process as wide as mesocoxa, and first segment of metatarsi as long as two following segments combined. Carphontes shares these characters with Atrypanius Bates, 1864 and Nyssodrysina Casey, 1913, but differs by the narrower prosternal process, as wide as approximately 1/3 of the procoxa. In Atrypanius and Nyssodrysina the prosternal process is at least ½ as broad as one procoxa, and the elytral length is approximately twice the humeral width. Also in Nyssodrysina, the ovipositor projects beyond the elytral apices.
