Genus Evarcha Simon, 1902

Type species.

Evarcha falcata ( Clerck, 1757) , by subsequent designation.

Diagnosis.

Evarcha are medium-sized plexippine salticids displaying a vast diversity in genital morphology: the embolus may be short, stout and compact or range to very long and filamentous; tegulum ranges from round, oval to conical and may bear distinctive outgrowths / expansions; single RTA present; insemination ducts range from broad and membranous to thin and tube-shaped; Leg III longer than IV ( Wang et al. 2024; Zamani et al. 2017; Żabka 1993). However, it has been suggested that Evarcha , as currently defined, acts as a ‘ dumping ground’ genus and likely harbours many unrelated species, and cryptic generic diversity ( Kanesharatnam and Benjamin 2020). Thus, a universal definition of the genus is difficult to propose ( Wang et al. 2024).
