Key to the species of the genus Hemisemidalis 1 Male ectoproct narrowing caudally, pointed in lateral view; distal part of paramere narrow, elongated (Figs 235A, B) Hemisemidalis sinensis - Male ectoproct stout caudally (Fig. 234B); distal part of paramere short, broad (Fig. 234D) 2 2 Processus terminális of hypandrium caudo-laterally with a pair of strongly sclerotized projections (Fig. 234C) 3 - The weakly developed processus terminális of hypandrium without a pair of strongly sclerotized projections (Figs 231, 233) 4 3 End of processus terminális with a knob in lateral view (Fig. 234B); the two caudolateral projections are connected with a heavily sclerotized belt (Fig. 234C) Hemisemidalis pallida - End of processus terminális narrowing caudally in lateral view; the processus terminális of hypandrium only weakly sclerotized between the two caudo-lateral projections (Fig. 232) Hemisemidalis hreblayi 4 Processus terminális of hypandrium distinct (however short), with a shallow median incision (Fig. 231) Hemisemidalis fulvipennis - Processus terminális of hypandrium rudimentary, without median incision (Fig. 233) Hemisemidalis kasyi Key to the species of the genus Conwentzia 1 Paramere very broad and short; width at its middle part is about half or 1/3 of the length in lateral view (Fig. 237) Conwentzia inverta - Paramere slender (Fig. 241 A), or moderately broad (Fig. 244) 2 2 Paramere arched in lateral view; both proximal and distal parts curved upwards (Figs 240, 244) 3 - Paramere not arched; its proximal part straight, or slightly wavy 4 3 Middle part of paramere much broader than proximal part (Fig. 244) Conwentzia sinica - Middle part of paramere slightly broader only than proximal part (Fig. 240) Conwentzia orthotibia 4 Distal part of paramere only slightly curved upwards (Figs 238B, 245B) 5 - Distal part of paramere strongly curved upwards (Figs 239D, 241 A, 243C) 6 5 Male ectoproct slightly longer than broad (Fig. 238A) Conwentzia nietoi - Male ectoproct about 2 times as long as broad (Fig. 245B)

.. Conwentziayuanguiana 6 Distal part of paramere more or less straight, and narrow already at its beginning (Fig. 241 A) 7 - Distal part of paramere curved, and broad at its beginning (Fig. 239D) 8 7 End of the internal projection of ectoproct distinctly forked; upper branch of this fork in caudal view much longer than ventral one (Fig. 24IB); number of antennái segments 30-36 Conwentzia pineticola - End of the internal projection of ectoproct slightly forked; the fork represented only by two knobs of cca. equal length in caudal view (Fig. 242); number of antenna!
