Figures 2F, 4E–H, 8A–F, 9A–E, 10A–E
MATERIAL EXAMINED: HOLOTYPE: South Africa: Western Cape Province: Sneeukop, Cederberg, CWA (32°21.22′S 19°09.17′E, 1615 m), October 7, 2007, E. Nortle, S. Kritzinger-Klopper, 13, (NCA 2012 /2264). PARATYPE: same locality as for holotype (32°21.33′S 19°09.92′E, 1843 m), March 6, 2006, same collectors as holotype, 1♀ (NCA 2012 /2237).
ETYMOLOGY: The species name refers to the Cederberg mountains, where this species was collected.
DIAGNOSIS: Male embolus without flanges (figs. 4E, F; 9D, E). It can also be separated from H. fulva and H. tuckeri by the lower number of maxillary cuspules (32 [fig. 8B] vs. 42 [fig. 6B] and 40 [fig. 17B] respectively). Females can be distinguished by their spermathecae, which are short and widely separated (fig. 10E).
