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 (

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

vein downcurved, vein M

more than 1.5 times longer than Cu

terminal section.
Male terminalia
(
Figs 1–6
) very distinct, since tergite 9 and gonocoxites are not fused. Sternite 8 (
Fig. 1
) membranous medially, edges strongly narrowing proximally. Setae of sternite 8 long but emerge only on distal edges. Tergite 8 (
Fig. 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
) long, evenly setose, caudal part divided into 2 long lobes. Cerci (
Fig. 3
) widely separated, setose, broadened subapically. Genital complex (
Figs 5–6
) of an intricate form. Hypoproct much narrower than cerci. Caudal lobes of gonocoxites with a blunt lateral apex (
Fig. 6
), with long caudal setae (
Fig. 5
); 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.
