See Brooks (2005) and Yang et al. (2011) for generic diagnosis and synonymy. Combining species from different genera with Sybistroma, Brooks</p> <p>(2005: 120) was inaccurate in checking gender endings, using all genders: masculine (eucerus, flavus, inornatus etc.), neuter (obscurellum, sphenopterum) and feminine (setosa). Yang et al. (2011) used masculine gender for Chinese species.</p> <p>Grichanov &amp; Kazerani (2014) proposed the use of feminine ending, following</p> <p>Schiner’s and Negrobov’s proposal. I use here the feminine gender for all species names.</p></div> 	https://treatment.plazi.org/id/17150076F00F2D12FE351B72FC6F078A	Public Domain	No known copyright restrictions apply.

This species belongs to S. incisa group of species and keys to S. apicicrassa (Yang et Saigusa, 2001) known from</p> <p>Henan and Shaanxi provinces of China (Yang et al., 2011). Its cercus superficially resembles the cercus of S. incisa, but the latter species differs from the new species in the short antennal postpedicel, preapical arista-like stylus, two dark swellings on stylus, entirely yellow hind femur, fine morphological characters of hypopygium</p> <p>(Yang et al., 2011: fig. 692). S. apicicrassa differs from the new species in the simple cercus, dark swelling on stylus, entirely yellow hind femur, fine morphological characters of hypopygial appendages (Yang et al., 2011: fig. 678).</p> <p>ETYMOLOGY. The species is named for the Russian entomologist, Dr. Genrik</p> <p>Davidyan, one of the collectors of the type series.</p></div> 	https://treatment.plazi.org/id/17150076F00E2D16FF271BE9FFB40077	Public Domain	No known copyright restrictions apply.
