Description
SIZE. Habitus ( Fig. 34A View Fig ), length 0.60 mm.
COLOUR. Dark brown, pubescence, legs and antennae dusky yellow.
HEAD. Head without a linear depression between or behind the eyes, width across eyes 0.20 mm: antennomeres III–XI length 0.37 mm, III–IX length 0.19 mm, X–XI length 0.11 mm. globular; mentum and prementum obscured.
PRONOTUM. Length 0.16 mm, width 0.24 mm, sparsely pubescent without foveolae but with six foveae along the posterior margin in two pairs of three the outer pair very small, the median two pairs larger, merging to form two large foveae; sides rounded slightly concave to acute hind angles, bordered, the border not continuing along the posterior margin which has a sinuous emargination in front of the scutellum ( Fig. 34B View Fig ).
ELYTRA. Length 0.40 mm, width 0.32 mm; pubescent and foveolate markedly contrasting with the pronotum.
MESOVENTRITE. Median process of mesoventral collar almost reaching posterior margin of mid-keel; mid-keel parallel-sided, the posterior angles rounded not reaching mesocoxae, raised sharply before joining keel; keel with ± four setae, narrow, terminating in a point at the interruption of the mesocoxal borders; mesoventral lateral margins angled and serrate posteriorly; humeri toothed ( Fig. 34C View Fig ).
METAVENTRITE. Length 0.15 mm, setose, disc simple, width across spines 0.09 mm, spines narrow, sharply pointed.
WINGS. Macropterous.
GENITALIA. Aedeagus as Fig. 6 View Fig Fa–b. Female not known.
Remarks
The short parallel sided mid-keel is only likely to be confused among the New Caledonian species with C. houailou sp. nov. from which it differs by its smaller size.
