Alycus C.L. Koch, 1842

Type species: Alycus roseus C.L. Koch, 1841 or 1842 from Germany; by monotypy .

Differential diagnosis. The genus can be segregated from the other genera of the family by the robust and nonelongated chelicera ( Figs. 1 , 135E ) and three pairs of pseudacanthoid eupathids with long cilia on the palpi ( Fig. 8 ; Uusitalo 2010: figs. 18, 39).
