Neosisyphus rubrus (Paschalidis, 1974) (Figs. 29, 30B)

Montreuil 2015b: 20, 28

Sisyphus rubrus Paschalidis 1974

Paschalidis, 1974b: 299

Type locality: Castle Gorge (South Africa)

Size: Male: length: 9.0–6.0 mm; width: 4.1–3.0 mm. Female: length: 8.7–6.0 mm; width: 4.0–3.0 mm.

Diagnosis: N. rubrus closely resembles N. macrorubrus (Paschalidis 1974) . However, the species can be distinguished by the lateral protrusions at the apices of the parameres in N. rubrus (Fig. 30B), which are lacking in N. macrorubrus .

Examined non-type material: See Supplementary information.

Distribution: N. rubrus is distributed in upland and coastal, moist grassland and savanna (Davis et al. 1999) in southeast Africa (Fig. 31).

Conservation status: N. macrorubrus and N. rubrus are listed as Least Concern species on the IUCN Red Data List (Davis 2013 e, f).

Remarks: It has been suggested that on grounds of gender, the spelling of N. rubrus and N. macrorubrus should be changed to N. ruber and N. macroruber respectively (Davis et. al. 1999; Davis et al. 2008, Davis 2013 e, f). It should be noted that; “ ruber ” is a masculine classical adjective, which has been used in a rare case as an alternative form of ‘ rubrus ’ (Brown, 1954). However, the original description of each species does not specify the etymological meaning of the specific name ‘ rubrus ’ (Paschalidis, 1974 b). According to ICZN (article: 31.2.2) “Where the author of a species-group name did not indicate whether he or she regarded it as a noun or as an adjective, and where it may be regarded as either and the evidence of usage is not decisive, it is to be treated as a noun in apposition to the name of its genus”. Therefore, rubrus and macrorubrus must be treated as indeclinable names.
