( Figs 50–57 View Figs 50–57 , 60 View Fig )

Holotype male ( BMNH): Indonesia: Sulawesi: Utara, Dumoga– Bone N. P., “1440 camp”, 30.6.– 25.7.1985, Malaise trap. (left apical 4 flagellomeres lost, some tarsomeres, incl. all right hind tarsus, as well as all but fore left 5th tarsomeres with claws, lost).

Z. 1985. 078 – Sulawesi Utara: Dumoga Irrigation Project, Toraut , 10–19.viii.1985, A. H. Kirk-Spriggs. – Malaise trap, irrigated rice vars. Aceh & Citandui .

56–57, 0.1 mm for Figs 52–55 View Figs 50–57

Measurements (holotype): wing length: 5.75 mm, head + thorax 1.75 mm, abdomen 5.1 mm.

Male terminalia. Setae on sternite 8 almost symmetrical ( Fig. 50 View Figs 50–57 ), setae long thick and arranged in one row; sternite 8 submedially with a darker transverse thickening. Tergite 8 about as long as broad, dark setae evenly emerge on its apical 2/3 ( Fig. 51 View Figs 50–57 ). Tergo-gonocoxal complex longer than broad, caudal lobes ( Fig. 52 View Figs 50–57 ) comparatively short, broadly bifid, i.e. the complex with deep medial emargination ( Fig. 52 View Figs 50–57 ). Medial processes partly overlapping in dorsal view, short and blunt, better seen in caudal view ( Figs 52, 55 View Figs 50–57 ). Gonostyli broad basally ( Fig. 22 View Figs 18–23 ), but apical 2/3 rather narrow. Gonostylus not much different in dorsal view and in its broadest extension ( Fig. 54 View Figs 50–57 , vs Fig. 53 View Figs 50–57 ). Caudal view ( Fig. 55 View Figs 50–57 ) reveals the large, widely rounded extension of the complex subventrally. Phallic organ medium large, aedeagus short but high ( Figs 56–57 View Figs 50–57 ); ejaculatory apodeme comparatively short, rather high ( Fig. 56 View Figs 50–57 ), but rather narrow in dorsal view, without lateral (horizontal) lobes ( Fig. 57 View Figs 50–57 ).

Egg ( Fig. 60 View Fig ). This is a formerly unknown morphological type of egg (see PLACHTER 1981).

Etymology. The specific epithet of the new species refers to its type locality Sulawesi Utara (=

North Sulawesi).
