Ocellarnaca wolffi ( Krausze, 1906)

Figs. 21 J–K, 22I–L, 24H

Material examined. Vietnam: Tonkin, Lang Son Province, Than-Moi (currently Dong Mo ), (21°33'N, 107°1'E), 1.vi.–31.vii.1892, coll. H. Fruhstorfer det. H. Karny— 1 female (labeled " Allotype " by H. Karny), 1 male (London BMNH); same data— 1 male (Wien NHMW) .

Remark. The types of species described by Krausze are lost. The specimens studied have been identified by H.H. Karny.

Diagnosis. Wings rather short, in both sexes not reaching tip of abdomen ( Figs. 21 J–K). Male ninth abdominal tergite with two pairs of projections above apical margin; dorsal projections black, lobate with convex external surface; ventral projections narrow styliform, substraight with acute tip ( Fig. 22J ). Male subgenital plate furrowed in midline, with sub-angular apical margin; styli inserted at apical lateral angles. Female seventh abdominal sternite little lobularly prolonged from hind margin; subgenital plate swollen on both sides, flat in central area of basal half; apical margin terminating into a pair of acute lateral angles, rather widely separated from each other ( Fig. 24H ); ovipositor strongly bent in subbasal area, afterwards only faintly curved, nearly straight; with subapical widening ( Figs. 22 K–L).
