Evarcha degeni Wiśniewski & Wesołowska, 2024, sp. nov.

Evarcha degeni sp. nov. urn:lsid:zoobank.org:act: E533B849-4A27-47B5-A1F3-22C1329FFE13 Fig. 16 Diagnosis This species is related to Evarcha prosimilis Wesołowska & Cumming, 2008. It can be recognized by the shape of the tibial apophysis. The apophysis of Evarcha degeni sp. nov. has only a small notch at the tip, whereas in Evarcha prosimilis the notch is larger and the apophysis has two tips of unequal length (compare Fig. 16F with Wesołowska & Russell-Smith 2000, sub E. similis: fig. 47). Etymology The specific name honours the Swiss eminent naturalist Edward Degen (1852–1922) who collected the type of this species. Material examined Holotype UGANDA • ♂; Entebbe; E. Degen leg.; NHM.
