Description
SIZE. Habitus ( Fig. 25A View Fig ), length 0.67 mm.
COLOUR. Dusky yellow.
HEAD. Shallowly foveolate between eyes, width across eyes 0.21 mm; antennomeres III–XI 0.32 mm long, III–IX 0.16 mm long, X–XI 0.16 mm; mentum as Fig.4A. View Fig
PRONOTUM. Length 0.19 mm, width 0.29 mm, sparsely pubescent, base with a series of five or six foveae of approximately equal size and spacing but with a wider gap opposite the scutellum; sides sharply angled, slightly convexly curved to rectangular hind angles, front angles obtuse, not evenly rounded, conspicuously bordered, the border not continuing along the posterior margin which has a sinuous emargination before the scutellum ( Fig. 25B View Fig ).
ELYTRA. Length 0.43 mm, breadth 0.37 mm; foveolate, the foveolae more conspicuous and denser in the basal half.
MESOVENTRITE. Medial extension of collar short, pointed; mid keel wider anteriorly, hind angles with carinae to mesocoxae, medially raised with a ridge; keel narrow with ± three setae tapering to a point past the mid-point of the mesocoxae; mesoventral lateral borders serrate in posterior half; humeri toothed ( Fig. 25C View Fig ).
METAVENTRITE. Length 0.13 mm, no spines detected but two clear foveae may mark their insertion points if abraded, width across these 0.11 mm, with a large medial fovea on disc in front the mesocoxae ( Fig. 7C View Fig ), disc slightly depressed behind this; mesocoxal posterior margins serrate.
WINGS. Macropterous.

Remarks
Distinguished from other species from the Solomon Islands in this group by the narrower mesoventral mid-keel and the form of the male aedeagus.
