Treatment

Leptomorphus papua View in CoL sp. n.

( Figs 43–49 View Figs 43–49 )

Holotype male ( BMNH): Papua New Guinea: Madang Prov., rain forest near Biteta Village , iv. 1987, Malaise trap (C. J. H. Godfray). Antennae and most of its legs lost, only right mid and hind tibiae and femora, as well as left hind tibia and femur present; wings torn, apices lost . Paratype male ( HNHM, genitalia prepared and kept in a plastic microvial with glycerol): same data. Antennae, wings and all legs lost, only left fore femur and right hind femur remained .

Measurements (holotype): wing length: 5.1 mm, head + thorax 1.75 mm, abdomen 3.8 mm.

Diagnostic characters. Prefrons ventrally with 2 (3) strong setae only. Metanotum partly yellow. Terminal section of Cu 1 less downcurved, M 3 about 1.2 times as long as terminal section of Cu 1.

Male terminalia. Pregenital (8th) sternite ( Fig. 43 View Figs 43–49 ) strongly narrowing proximally, with 3 pairs of lateral setae only. Sternite 8 at about its basal 1/3 with a darker transverse thickening. Tergite 8 ( Fig. 44 View Figs 43–49 ) broader than long, cranial 2/5 bare, setae are not on extreme edge. Male genitalia with tergite 9 and gonocoxites fused into a tergo-gonocoxal complex, which is about as high as broad (see ratio on Fig. 45 View Figs 43–49 ). Caudal process of the complex separated from the other parts but on a small section ventrally ( Figs 45, 48 View Figs 43–49 ). Caudal processes serrate, both apically and basally ( Figs 46, 48 View Figs 43–49 ). Medial process of gonocoxite simple, not double, dark processes observable. Gonostyli very small ( Fig. 45 View Figs 43–49 ), embraced deeply into the medial part of gonocoxites; gonostylus with one – rather blunt – apical process only. Gonostyli rather different in dorsal view and in the view of their broadest extension ( Fig. 47 View Figs 43–49 , vs Fig. 46 View Figs 43–49 ). Aedeagus ( Fig. 49 View Figs 43–49 ) long, apex blunt. Ejaculatory apodeme not sclerotised, membranous ( Fig. 49 View Figs 43–49 ). Base of aedeagus continued into a pair of blunt processes (? to replace ejaculatory apodeme).
