Rugicarventus n.gen.

Type species: Rugicarventus pygmaeus n. sp.

Diagnosis: Apterous, small, and compact; colouration dark piceous to black, surface glabrous, covered with rugosities and punctures. There is no Carventinae genus known from New Caledonia resembling this genus and it is therefore considered and described as new.

Description. Head: Much wider than width across eyes; genae as long as clypeus dilated apically; antenniferous lobes diverging apically, their apices blunt; antennae distinctly longer than width of head, segment I longest; eyes granulate; postocular lobes angulate converging posteriorly to ring like collar; rostrum arising from an open atrium, rostral groove shorter than head.

Pronotum: Strongly transverse, anterolateral angles at a lower level than disk rounded; surface of disk raised and rugose, lateral margins carinate, posterior margin slightly convex and deeply sulcate separating it from mesonotum.

Mesonotum: Fused to metanotum and mtg I+II forming a continuous plate, this inflated medially with ill defined transverse grooves indicating the limits of thoracic segments; surface roughly sculptured, lateral margins carinate.

Abdomen: Tergal plate elevated medially its surface with carinate posterior margins of mtg III–VI and intermediate longitudinal carinae separated by deep depressions; deltg I+II fused and triangularly expanded anteriorly, reaching to pronotum; lateral margins of deltg III–VII carinate, disk deeply punctured.

Venter: Pro-, meso-, and metasternum and sternites I+II fused but marked by transverse impressions; meso- and metasternum flattened medially, laterally with fine velvet-like pilosity; sternites III–VII separated by sinuate transverse sutures, surface smooth medially, rugose laterally; all spiracles lateral and visible from above.

Legs: Slender, unarmed; trochanters fused to femora, fusion line distinct; claws with fine pseudopulvilli.

Etymology. Refers to the rugose dorsal surface and the genus Carventus .
