Key to Genera and Species of the Rophitinae View in CoL of China

1. Forewing with three submarginal cells ( Fig. 1 View Fig , A); five last flagellomeres of male rolled to triangular spiral ( Fig. 1 View Fig , C); metasomal terga with dense long hairs (Genus Systropha View in CoL ). [Female: 1st flagellomere as long as 2nd and 3rd combined ( Fig. 1 View Fig , B); pubescence of metasomal terga grayish white. Male: each of S2 and S3 with two long sharp lateral teeth ( Fig. 1 View Fig , D); T7 broadly emarginate posteriorly ( Fig. 1 View Fig , I) ............................... ................................. Systropha curvicornis ( Scopoli, 1770) View in CoL

– Forewing with two submarginal cells ( Fig. 2 View Fig , A; Fig. 5 View Fig , B); flagellum of male not modified; metasomal terga without dense long hairs............................................................................. 2

2. The first submarginal cell larger than the second one obviously ( Fig. 2 View Fig , A); body with yellow integumental markings (Genus Morawitzella View in CoL ). [Female: unknown. Male: body length 3.5- 4.0mm; the head much broader than long ( Fig. 2 View Fig , D); the apical process of S8 not enlarged, the base of S8 truncate, not bilobed ( Fig. 2 View Fig , C)] ................. Morawitzella nana ( Morawitz, 1880) View in CoL

– The first submarginal cell nearly as large as the second one ( Fig. 5 View Fig , B); body without yellow integumental markings ............ 3

3. Metasomal terga with paler colored apical hair bands; dorsal surface of propodeum shorter than scutellum; S7 of male with distinct slender dorsal lobes ( Fig. 3 View Fig , C; Fig. 4 View Figs , C; Fig. 5 View Fig , A) .. ................................................................................................ 4

– Metasomal terga without apical hair bands, only with transverse series of hairs; dorsal surface of propodeum as long as or longer than scutellum; S7 of male without distinct slender dorsal lobes. (Genus Dufourea View in CoL ) ..................... Key to species not included

4. Labial palpus usual, its 1st and 2nd segments twice as long as 4th segment ( Fig. 3 View Fig , B); labial palpus shorter than maxillary palpus; frons of female only with usual hairs, without spines; S6 of male with blister-shaped thickenings, median part covered dense hairs, without longitudinal ridge (Genus Rhophitoides ). [T1-T5 of both sexes with whitish apical hair bands; S6 of male sheet-like midapically, broad, two lateral teeth obvious; posterolateral margin of S6 of male with broad and round projection ( Fig. 3 View Fig , E)] .............................................................. .............................. Rhophitoides canus ( Eversmann, 1852)

– Labial palpus very long, its 1st and 2nd segments greatly elongate and flattened ( Fig. 5 View Fig , D); labial palpus longer than maxillary palpus; frons of female with modified hairs forming sharp and long spines; S6 of male flattened, without blistershaped thickenings, median part with longitudinal ridge. (Genus Rophites View in CoL ) ................................................................................ 5

5. Female: frons with 20-25 radixes spines; 1st flagellomere longer than 2nd obviously; mesoscutum and scutellum covered densely long yellowish brown hairs; Male: median ridge of S6 high, only apex covered hairs, posterolateral margin of S6 with long, pointed, spin-shaped projection ( Fig. 5 View Fig , E); both sexes body length 9.0-10.0mm ................................................................... ............................. Rophites quinquespinosus Spinola, 1808 View in CoL

– Female: frons with 32-38 radixes spines ( Fig. 4 View Figs , A); 1st flagellomere as long as 2nd; mesoscutum and scutellum covered sparsely short yellowish brown hairs; Male: median ridges of S6 low and piliferous throughout, posterolateral margin of S6 with short, tooth-shaped projection ( Fig. 4 View Figs , B); both sexes body length 8.0-9.0mm .........
