Type species.

Kimberleytyphlus carrboydianus sp. nov.

Diagnosis.

Genus of the " Illaphanus phyletic series" (sensu Giachino 2005), with species strongly characterised by normal metatrochanters; metafemora non dentate; elytra not reduced at tip; elytral disc without longitudinal grooves and bearing three setae, scaly microsculpture and 9th pore of the umbilicate series in normal position (placed after the 8th one); aedeagus with median lobe subrectilinear, size of basal bulb normal and parameres each bearing one apical seta. Labial tooth absent.

Description.

Species of a medium size (TL mm 1.57-1.59) and anophthalmous. Integument depigmented but well sclerified, with strong microsculpture and covered with short and sparse pubescence.

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

Pronotum trapezoidal, with sides not sinuate in the basal third, denticulated at the basal third. Basal angles obtuse, sharp, not rounded; basal border slightly narrower than anterior border; presence of two marginal setae, the posterior one placed near basal angles.

Elytra subrectangular elongate, separately rounded, not truncated and apically only slightly emarginated, convex, without longitudinal grooves. Elytral striae absent (except sutural stria). Lateral margin starting from the humeral area and distinctly crenulate up to the level of 8th-9th pores of the umbilicate series. Scutellar pore present, large and umbilicate; umbilicate series of type B (sensu Jeannel 1963; Giachino and Vailati 2011); disc bearing three setae.

Legs relatively long and slender. Pro- and metafemora unarmed; metatrochanters normal, two slightly dilated protarsomeres, without adhesive phanerae in males.

Aedeagus relatively small, median lobe long, subrectilinear with basal bulb of normal size. Parameres long, bearing one apical seta. Endophallus without any sclerified phanerae.

Etymology.

The name combines the name Kimberley (region where the type locality is located) and the Greek suffix - typhlos (meaning blind).

Species included.

Currently only K. carrboydianus sp. nov. belongs to this genus.
