Synonyms
Sticholotidini Weise, 1901: 430.
Diagnosis
Body moderately convex, usually glabrous. Head with antennal insertions usually exposed, very rarely with antennal grooves ventrally along the inner margins of eyes. Antenna 10- or 11-segmented with 1-4-segmented club. Pronotum without line or ridge separating anterior corners from the pronotal disk. Prosternum broad between coxae and usually with marginal lines or carinae. Tarsi 4-segmented with claws usually simple or thickened at base. Tibial spurs absent. Abdomen with 5 ventrites; ventrites 1 and 5 longer than 2-3 combined. Abdominal postcoxal line incomplete. Male genitalia: tegmen symmetrical, parameres long with one or more setae apically; penis sclerotised, simple with T-shaped capsule.
Distribution and Biology
Circumtropical, with greatest diversity in the Oriental and Ethiopian regions. About 40 genera are classified in this heterogenous tribe that seems to be characterised only by maxillary palps apically geniculate with narrowed and pointed terminal segment, abdomen 5-segmented and prosternum relatively broad between coxae. Only 2 genera occur in Australia. Sticholotidini are probably scale predators but nothing is known about biology of the Australian species.
