The G. typica species-group

Diagnosis. Species of the group are superficially indistinguishable from each other and the identification requires the examination of the genitalia structures. It is defined by the male genital capsule that is characterised by the distally tapered valva which is shorter than the tegumen-vinculum complex, the moderately long sacculus with a claw-shaped upcurved distal process, and the broadly triangular lobes of the anellus with serrulate surface. The vesica of the species-group is clearly subdivided into the proximal tubular and the distal dilated sections with the latter one bearing a robust claw-shaped terminal cornutus.
