Key to subgenera of Oxylakis Redtenbacher

1. Male cerci short (length and width almost equal), with medial lobe located in distal part; male genitalia with a pair of distinct sclerotized hooks.................................................................. Indolakis Gorochov, 2013

- Male cerci long (length distinctly or much greater than width), with process (often divided into 2–3 lobules or hook-like spines) located at base; male genitalia without distinct sclerotized hooks........................................ 2

2. Median ocellus indistinct or very small, greyish, situated at middle of space between lower parts of antennal cavities and rather far from base of rostral tubercle. Male cerci without any distinct widening near apex; male genitalia without large semiscleritized lobes posteriorly........................................................... Oxylakis Redtenbacher, 1891

- Median ocellus very large, whitish, completely occupied space between antennal cavities and reaching base of rostral tubercle (Fig. 27). Male cerci with rather large lamellar widening near apex (Fig. 32); male genitalia with large semisclerotized lobes posteriorly.......................................................................
