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, 38View FIGURES 34–38). Ventral plate of aedeagus markedly wider and short, distinctly angled near the base, quite blunted apically ( Figs. 35, 37View 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. 42View FIGURES 39–46, 47View FIGURES 47–50 and Enushchenko & Semenov (2016: Figs. 12View FIGURES 7–12, 13View FIGURES 13–16))......................... 2

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

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