Description

SIZE. Habitus ( Fig. 57A ), length 0.69 mm.

COLOUR. Yellow brown, antennae, legs and pubescence yellow, shining. HEAD. Without a linear depression behind the eyes, width across eyes 0.22 mm, ventral side of neck with a band of shallow, slightly elongate foveolae; antennomeres III–XI length 0.34 mm, III–IX length 0.19 mm, X–XI length 0.15 mm globular; mentum as Fig. 4A.

PRONOTUM. Length 0.19 mm, width 0.29 mm, densely pubescent and foveolate, with a pair of short, poorly formed linear depressions extending forwards from the base; lateral margins sharply angled medially then concave to acute hind angles, bordered, the border on the posterior margin enlarged convexly either side of the medial emargination opposite the scutellum which is well marked ( Fig. 57B ).

ELYTRA. Length 0.46 mm, width 0.41 mm, shallowly foveolate contrasting with the pronotum.

MESOVENTRITE. Collar with reticulation confined to a small median triangular area and on the parallelsided medial extension; mid-keel parallel-sided widening sharply before meeting collar, posterior angles effaced before joining mesocoxal anterior borders; keel foveolate with ± ten setae, parallel-sided to rounded termination between the mesocoxae; mesoventral lateral margins serrate in posterior half; humeri bluntly toothed ( Fig. 57C ).
