Amphialycus Zachvatkin, 1949

Type species: Amphialycus pentophthalmus Zachvatkin, 1949 from Ukraine; by original designation .

Differential diagnosis. The genus can easily be segregated from the other genera of the family by the elongated and robust chelicera ( Figs. 34 , 135F ), finely striated anterior pair of lateral eyes ( Uusitalo2010: fig. 75, glabrous in one case), and microtrichous palpal eupathids, which may be separate or basally fused ( Figs. 35 vs. 82; Uusitalo 2010: figs. 78 vs. 85).
