Key to the Gyrophaena species of the laetula group of Kazakhstan

1 Pronotum with several small, scattered punctures not forming longitudinal rows and two rather large punctures near base of pronotum. Elytra between cells of microsculpture without micropunctures, but with several distinct tubercles. Medial teeth of male abdominal tergite VIII quite wide and long ( Figs. 36, 38 View FIGURES 34–38 ). Ventral plate of aedeagus markedly wider and short, distinctly angled near the base, quite blunted apically ( Figs. 35, 37 View FIGURES 34–38 ).................................. G. aryanamensis sp. nov.

- Pronotum with two longitudinal rows of punctures, usually with several additional punctures closer to lateral margins of pronotum. Elytra between cells of microsculpture with sparse, small shallow punctation and few tubercles only on external posterior angles. Median teeth of male abdominal tergite VIII narrower and rather small. Ventral process of aedeagus more elongated, arched, quite acute apically ( Figs. 42 View FIGURES 39–46 , 47 View FIGURES 47–50 and Enushchenko & Semenov (2016: Figs. 12 View FIGURES 7–12 , 13 View FIGURES 13–16 ))......................... 2

2 Elytra with indistinct, sparse, and small punctation. Median teeth of male abdominal tergite VIII rather thin and small ( Figs. 43–44 View FIGURES 39–46 , 48 View FIGURES 47–50 ). Lower edge of ventral process of aedeagus somewhat flat; dorsal projection of internal sac irregularly elongate, slightly widening to apex ( Figs. 42 View FIGURES 39–46 , 47 View FIGURES 47–50 )........................................................... G. hochhuthi

- Punctation of elytra markedly dense. Median teeth of male tergite VIII stout, wide, and obtuse ( Enushchenko & Semenov 2016: Figs. 14 View FIGURES 13–16 ); lower edge of the ventral plate slightly angular in outline; dorsal projection of internal sac regularly elongate ( Enushchenko & Semenov 2016: Figs. 12 View FIGURES 7–12 , 13 View FIGURES 13–16 )...................................................... G. congrua
