Leptomorphus alienus View in CoL sp. n.

( Figs 1–6 View Figs 1–4 View Figs 5–6 )

Holotype male ( BMNH): Indonesia, Seram , Solea, August 1987, Malaise trap, M. C. DAY leg. (Flagellomeres, apical to 7th on the left side and to 9th on the right side, broken off; some tarsomeres also lost, incl. all the 5th tarsomeres with claws.)

Measurements (holotype): wing length: 5.75 mm, head + thorax 1.9 mm, abdomen 5.75 mm.

Diagnostic characters. Prefrons ventrally with 6 strong (black) setae. Wing tip dark. Pleura mostly dark, but light just around anterior spiracle. Terminal section of Cu 1 vein downcurved, vein M 3 more than 1.5 times longer than Cu 1 terminal section.

Male terminalia ( Figs 1–6 View Figs 1–4 View Figs 5–6 ) very distinct, since tergite 9 and gonocoxites are not fused. Sternite 8 ( Fig. 1 View Figs 1–4 ) membranous medially, edges strongly narrowing proximally. Setae of sternite 8 long but emerge only on distal edges. Tergite 8 ( Fig. 4 View Figs 1–4 ) definitely broader than long, caudal part partly separated, basally with short setulae, medially with numerous thin setae. Long and thick setae of tergite 8 emerge only apically (11–12) and laterally (numerous ones). Tergite 9 ( Figs 2–3 View Figs 1–4 ) long, evenly setose, caudal part divided into 2 long lobes. Cerci ( Fig. 3 View Figs 1–4 ) widely separated, setose, broadened subapically. Genital complex ( Figs 5–6 View Figs 5–6 ) of an intricate form. Hypoproct much narrower than cerci. Caudal lobes of gonocoxites with a blunt lateral apex ( Fig. 6 View Figs 5–6 ), with long caudal setae ( Fig. 5 View Figs 5–6 ); medial part of the lobes with numerous, medially directed setae. Medial edges of gonocoxites with a comb of closely set thick black setae. Gonostyli small. Aedeagus robust, aedeagal apodemes with broadened “holes” on cranial apices (they are not sclerotised there).

Etymology. From the Latin “ alienus ” (= alien), referring to its difference from the other Oriental and Australasian species.
