Remarks.

The genus is apparently related to Anacypta and Xenoglena . The body is larger than in Anacypta but not so slender as in Xenoglena , moreover perfectly covered in scales. Further to the three species described, I have also encountered some undescribed species, all of them distributed in the Indonesian islands.

Description.

Body size: about 7.0-9.0 mm. Body shape flat. Gular sutures narrow, subparallel at apex. Frontoclypeal suture absent. Frons: longitudinal groove or depression absent. Cranium ventrally: tufts of long setae at sides absent. Submentum: ctenidium present. Antennal groove present. Eyes: size large, dorsal. Eyes number: four. Epicranial acumination absent. Lacinial hooks absent. Galea: shape clavate. Galea: ciliate setae absent. Mediostipes-Lacinia fused together. Palpifer: outer edge even. Mandibular apical teeth number: two, vertically situated. Mola absent. Penicillus (at base) long setae. Pubescence above mola or cutting edge absent. Ventral furrow absent. Basal notch shallow or absent. Labrum-Cranium not fused. Epipharyngial sclerite present. Lateral tormal process: projection curved downwards, processes not connected ( Airora ). Ligula: ciliate setae absent. Ligula rigid, not retroflexed, weakly emarginate. Hypopharyngeal sclerite absent. Antenna 11-segmented. Antennal club asymmetrical, sensorial fields present. Front coxal cavities externally closed, internally open. Pronotum transverse. Prepectus absent. Middle coxal cavities open. Elytra: long hairs absent. Epipleuron moderate. Elytral interlocking mechanism present, carinae reduced. Elytral punctation regular, scales present. Wing: radial cell oblong (or reduced), wedge cell present, cross vein MP3-4 present, cross vein AA1+2-3+4 present. Front tibiae: spines along side reduced. Hooked spur present. Claws: denticle absent. Parasternites number along ventrites III-VII: one. Spiculum gastrale absent. Tegmen composed of three parts.

Biology.

Unknown, probably predatory like Anacypta .

Distribution.

Indonesia (species that remain formally undescribed are known from Sulawesi and other islands).
