Scymnomorphus fulvus, from CSIRO.

Belongs within: Coccinellidae.

The Sukunahikonini are a circumtropical group of minute ladybird beetles with long, geniculate maxillary palps (Ślipiński 2007).

Characters (from Ślipiński 2007): Body minute (1–3 mm), moderately to strongly convex with head in repose deflexed and fitting closely under prosternum; dorsum usually with apparent dorsal vestiture. Head transverse, ventrally flattened, often with clypeal and frontal regions prominent anteriorly; clypeus emarginate around exposed antennal insertions, ventral side with short antennal groove accomodating scape and pedicel along inner margin of eye. Mandible small, triangular with single apical tooth and no mola; maxillary palp long, geniculate; terminal palpomere elongate and conical; labial palps slender, narrowly separated at base, inserted on distal end of prementum. Antenna 8- to 10-segmented with 1–3-segmented club. Pronotum almost always with line or ridge separating anterior corners from pronotal disc, often extending along lateral edge. Prosternum strongly reduced and narrow; prosternal process reduced to short triangular piece or narrow carina. Winged or wingless; wing with reduced venation, never with anal lobe. Elytral punctures sometimes in apparent rows; epipleuron narrow, usually incomplete apically, without cavities; lateral part of elytron often with carina parallel to lateral margin. Abdomen with five or six ventrites; ventrite 1 distinctly longer than 2. Abdominal postcoxal line incomplete, usually with associated oblique dividing line, pits and pores. Tegmen asymmetrical, parameres short to reduced with one or more setae apically. Ovipositor triangular, elongate, lightly sclerotised bearing short styli; spermatheca small and well sclerotised, multi-cameral.
