Scytachile emeljanovi sp. nov.

Fig. 14

Material. Holotype PIN 2785 / 3070, tegmen, Dzhailoucho.

Description. Tegmen slightly widening distally, obliquely truncate apically, 11.8 mm long, fuscous (more so in anterior zone of costal space), pale-speckled, with pale spots in stigmal area and at tornus. Surface faintly, densely punctate, more distinctly so at base and on clavus. Costal margin steeply convex proximally, straight distally; costal space broad. RA beyond nodus diverging from margin, some of anterior RA branches deeply forked. R forked at 0.4 tegmen length, CuA about same level, M just before nodal crossveins, RP and CuA1 more distally than M. RP, M, and CuA altogether with 12 terminations.

Remarks. The tegmen PIN 2555/2499 from Dzhailoucho, 14.6 mm long, is similar to the holotype (including the anterior zone of the costal space being more suffused), but distinct in the R forked at 0.3 tegmen length, CuA more distally, and pale specks absent; it possibly belongs to a different species.

Etymology. After entomologist Alexander F. Emeljanov.
