Lithosiopsisbicoremata sp. n.
9-10mm. This species is tentatively assigned to Lithosiopsis because it shares the distinctive pale, biarcuate forewing submarginal of those species and a similar postmedial, though this runs squarely distal to the reniform rather than in an obtuse angle as in papuana and torsivena. Unlike in those species, the submarginal is not accompanied by black patches. The labial palps are atypically short for the genus.



The male abdomen has the framed corematous sternite strongly modified, with central pouch flanked by two elongate structures, possibly further pockets, with pair of small coremata between them and just anterior to the central pouch. The genitalia have tongue-like valves as in Lithosiopsis but these are distinguished by central flexure within which are two shallow but complex lobes. The juxta is somewhat H-shaped. The female has the ostium set anteriorly beneath the moderately reduced seventh sternite. The ductus is moderate, straight, sclerotised, the bursa small, rugose, constricted at one third by a scobinate belt, basal to which a further slight ring of small spines. These various unusual features indicate the placement of the species requires further study.
