Type species.

Neoillaphanus callawanus sp. nov.

Diagnosis.

Genus characterised by: metatrochanters long and sharp; metafemora non dentate; elytra not reduced at tip; elytral disc with longitudinal grooves and bearing one seta; 9th pore of the umbilicate series in normal position (placed after the 8th one); aedeagus with median lobe curved, size of the basal bulb normal and parameres bearing two apical setae. Labial tooth absent.

Description.

Species of medium size (TL mm 1.93-2.04) and anophthalmous. Integument depigmented but well sclerified and covered with sparse pubescence.

Head large but narrower than pronotum; mandibles short and simple, without hyperplasias. Maxillary palpi ovoidal, swollen. Labium transverse, articulated; mentum not fused with submentum. Labial tooth absent. Antennae moniliform, without particular features.

Pronotum cordiform, sides sinuate at the basal third, denticulated before basal angles. Basal angles right, sharp at tips, not rounded; basal border narrower than anterior border; presence of two marginal setae, the posterior one placed before basal angles.

Elytra ovoidal short, separately rounded, not truncated and apically not emarginated; convex, with longitudinal grooves. Elytral striae absent (except sutural stria). Lateral margin starting from the humeral area, distinctly crenulate up to its half-length.

Scutellar pore present, large and umbilicate; umbilicate series of type B (sensu Jeannel 1963; Giachino and Vailati 2011); disc bearing one seta.

Legs relatively long and slender. Pro- and metafemora unarmed; metatrochanters long and sharp, two dilated protarsomeres in the male.

Aedeagus relatively large, median lobe long and curved with basal bulb of normal size. Parameres long, each of them bearing two apical setae. Endophallus with very small and poorly sclerified phanerae.

Etymology.

The name is derived by the combination of the Greek prefix Neo - (means new) and the name Illaphanus . Gender masculine.

Currently only one species belongs to this genus: N. callawanus sp. nov.
