The two new species of Scotophaeus described here, S. anahita sp. nov. and S. elburzensis sp. nov., are very similar in the structure of their epigynal sclerotization and somatic characters but are clearly different in the structure of the endogyne. In S. anahita sp. nov., the lateral ducts are spiraled (vs relatively straight, slightly curved outward in S. elburzensis sp. nov.) and the terminal lobes are smaller than the basal lobes and located anteriorly (vs larger than the basal lobes and located posteriorly in S. elburzensis sp. nov.) (cf. Fig. 19B, E). Similarly, they resemble S. nanus Wunderlich, 1995 in the form of the epigynal atrium, but the configuration of the spermathecal cluster is very different from both of the new species (see Wunderlich 1995: figs 6–8).
The specific epithet is a noun in apposition and refers to the divinity of the Waters (associated with fertility, healing and wisdom) in Persian mythology.
