Type species.

Pilbaraphanus chichesterianus sp. nov.

Diagnosis.

Genus characterised by very long and sharp metatrochanters; dentate metafemora; elytra not reduced at tip; elytral disc bearing three setae and longitudinal grooves absent; 9th pore of the umbilicate series in the normal position (placed after the 8th); aedeagus with median lobe not very curved, size of basal bulb normal and parameres bearing two apical setae. Labial tooth present and smooth. Differs from Magnanillus Baehr, 2017 by the absence of longitudinal elytral grooves.

Description.

Species of medium size (TL mm 1.37-2.18) and anophthalmous. Integument depigmented but well sclerified and covered with sparse pubescence.

Head from normal to large size, slightly narrower than pronotum; mandibles short and simple, without hyperplasias. Maxillary palpi ovoidal and swollen. Labium transverse and articulated; mentum not fused with submentum. Labial tooth present and smooth. Antennae moniliform, without particular features.

Pronotum subquadrate, with sides not or only slightly sinuate at the basal third, smooth or denticulated before basal angles. Basal angles right, sharp, not rounded; basal border as wide as, or only slightly narrower, than the anterior border; presence of two marginal setae, the posterior one placed just before basal angles.

Elytra subrectangular and elongated, separately rounded and depressed, not truncate and not emarginated apically, with longitudinal groove absent. Elytral striae absent (except sutural stria). Lateral margin starting from humeral area, distinctly crenulate up to at least half-length. Scutellar pore present, large and umbilicate; umbilicate series of type B (sensu Jeannel 1963; Giachino and Vailati 2011); disc bearing three discal setae.

Legs relatively short and stumpy. Unarmed profemora; posterior edge of metafemora dentate, metatrochanters very long and sharp, two dilated protarsomeres in the male.

Aedeagus relatively large, median lobe long and not very curved, with basal bulb of normal size. Parameres long and bearing two apical setae. Endophallus with poorly sclerified phanerae.

Etymology.

The genus name combines the Pilbara name with the suffix - phanus to recognise the genus Illaphanus . Gender masculine.
