Description
SIZE. Habitus ( Fig. 43A View Fig ), length 0.67 mm.
COLOUR. Yellow brown, head darker, pubescence, legs and antennae dusky yellow.
HEAD. With a shallow medial depression between eyes, width across eyes 0.22 mm; mentum with rounded anterior angles; antennomeres III–XI, length 0.37 mm, III–IX length 0.21 mm, X–XI length 0.16 mm.
PRONOTUM. Length 0.19 mm long, width 0.30 mm, base with series of four foveae on each side the innermost pair being smaller, the pair opposite the scutellary angles being larger than the others, surface sparsely pubescent without foveolae; sides rounded, becoming almost parallel to rectangular hind angles, bordered, the border not continuing along the posterior margin, median emargination opposite scutellum sinuate ( Fig. 43B View Fig ).
ELYTRA. 0.49 mm long, 0.40 mm wide, pubescent and foveolate contrasting with the pronotum.
MESOVENTRITE. Medial extension of collar widely based tapering to mid-point of mid-keel; mid-keel widest anteriorly then sides concave to narrower hind angles, sharply raised medially with a domed top before the keel; keel without setae, narrow parallel-sided to blunt termination close to base of mesocoxae ( Fig. 5C View Fig ); mesoventral lateral margins evenly rounded, without serrations; humeri toothed ( Fig. 43C View Fig ).
METAVENTRITE. Length 0.16 mm, sparsely pubescent, almost glabrous, disc simple, distance across spines 0.12 mm.
WINGS. Macropterous.
GENITALIA. Male aedeagus as Fig. 6 View Fig Ia–b. Female spermatheca globular.
Remarks
See remarks under C. deanei sp. nov. The broad median extension of the mesoventral collar coupled with the parallel-sided keel lacking setae distinguish this species.
