According to Levy (1999: 437) , Scotophaeus is a “cumulative taxon for medium-sized robust gnaphosids”, a problem that has not been resolved; the genus requires a full revision ( Murphy 2007: 51 ). However, the similarity of most of the somatic characters of the new species with Scotophaeus (e.g., habitus, shape of maxillae, cheliceral dentition, eye configuration [as illustrated in Murphy 2007 : fig. 374], presence of scopulae on metatarsi I and II [a diagnostic character of the genus, according to Levy 1999: 437 ]) as well as the form of the genital organs, with a wide epigynal depression and multi-chambered receptacles, indicate that this genus is the best candidate for generic assignment.
