Genus Nesochlamys Kirkaldy, 1907

Nesocharis Kirkaldy, 1907: 110 preoccupied by Nesocharis Alexander, 1903 (Aves) . Type species: Nesocharis kalypso Kirkaldy, 1907 , by monotypy. Nesochlamys Kirkaldy, 1907: 115

Type species: Nesochlamys vitiensis Kirkaldy, 1907 .

Notes: Since the name Nesocharis was preoccupied by the bird genus Nesocharis Alexander, Fennah (1950) used Nesochlamys as the first available name for the genus without comment. Unfortunately, he still used Nesocharis in his key to genera ( Fennah 1950).

Morphology. Body length: 3 3.1–3.9 mm.

Head: Head including eyes much narrower than pronotum. Vertex with strongly angulated anterior margin; median carina distinct, covering 1/2–3/4 of length of vertex; lateral carinae strongly elevated; subapical carina absent or present. Frons invisible in dorsal view; maximum width of frons more than twice apical width, steadily widening; position of maximum width of frons slightly dorsad of centre of frontoclypeal suture; median carina complete; lateral carinae slightly elevated. Frontoclypeal suture slightly semicircular, bent upwards, median part not reaching lower margin of antennal scape. Lateral carinae of anteclypeus weakly developed or absent. Rostrum not or just reaching hind coxae; subapical segment of rostrum 1.1–1.3 times longer than apical segment.

Thorax: Forewing with Sc+R+M fused, forming common stem; MA apically bifid. Hind tibia with 5 apical teeth.

Female genitalia: Ovipositor elongate, orthopteroid, slightly curved upwards, reaching or surpassing anal style; 8th sternite medially very short, not bent dorsad (in same plane as 7th sternite), posterior margin ushaped; anal segment square (as long as wide) or rectangular (slightly longer than wide) in dorsal view, sometimes apex wider than base; anal style longer than wide; 9th tergite without wax plates.

Remarks. Two species were previously recognised in Nesochlamys , N. vnigra ( Muir, 1931) from Vanuatu and N. kalypso from Fiji (= N. vitiensis ). Nesochlamys has not previously been recorded from Australia. In the course of this project five species of Nesochlamys were found in the Australian material. None of the species displays the distinct colour pattern (black, v-shaped mark on the forewings) of N. vnigra . Nesochlamys kalypso can be distinguished from the Australian species by the presence of a pointed tip on the apical lobes of the anal tube (rounded tips in Australian species). The Australian material of Nesochlamys contains 40 females collected in North Queensland and, due to similarity in external features, these could only be identified to genus level.
