Key to genus and tribe of Iassinae View in CoL (males) from China
1. Anterior margin of head well delimited, transition from crown to face distinctly angulate, ocelli on margin [ Krisnini View in CoL ]...... 4
- Anterior margin of head usually not well delimited, but if so, then ocelli on face below crown margin.................. 2
2. Pronotum strongly convex and declivous anteriorly; male subgenital plate short and concealed by pregenital sternite [Hyalojassini].............................................................................................. 5
- Pronotum slightly convex; male subgenital plate slender and extended beyond pregenital sternite [Iassini]............... 3
3. Style apophysis short and broad; apex of subgenital plate curved to middle............................ Iassus Fabricius View in CoL
- Style apophysis slender, elongate; apex of subgenital plate straight............................. Batracomorphus Lewis View in CoL
4. Forewings with extra crossveins in distal half ( Figs. 3, 6 View FIGURES 1–9. 1, 4, 7 ); eighth sternite wide, with many longfine setae ( Figs. 59–62 View FIGURES 43–65 ); subgenital plates without setae laterally........................................................... Krisna Kirkaldy View in CoL
- Forewings without extra crossveins in distal half; eighth sternite wide, without setae; subgenitalplate with many short spinelike setae laterally......................................................................... Gessius Distant View in CoL
5 Subgenital plates with mesal margins convergent distally, apices strongly bent or with toothlike ventral projection................................................................................. Trocniassus Dai, Dietrich & Zhang View in CoL
- Subgenital plates with mesal margins strongly divergent distally, apices unmodified................................ 6
6. Connective well delimited, joint with aedeagus flexible ( Figs. 36 View FIGURES 30–36 )................... Decliviassus Dai, Dietrich & Zhang View in CoL
- Connective membranous or immovably fused to aedeagus..................................................... 7
7. Sclerotized connective absent; apodeme of male style longer than apophysis ( Fig. 14 View FIGURES 10–25 )...... Siniassus Dai, Dietrich & Zhang
- Sclerotized connective present; apodeme of male style shorter than pophysis....................................... 8
8. Forewing appendix well developed, more than half width of inner apical cell; subgenital plates close together at base or absent...................................................................................... Trocnadella Pruthi View in CoL
- Forewing appendix weakly developed, less than half width of inner apical cell; subgenital plates well separated from each other at base.......................................................................................... 9
9. Ventral pygofer process well developed; aedeagus with bidentate distal processes..................... Coriojassus Evans View in CoL
- Ventral pygofer process absent; aedeagus with distal processes, if present, without teeth................ Hyalojassus Evans View in CoL
