Eyes 2 + 2, in ocular plate; 30–32 dorsal idiosomal setae, including one pair of humeral setae, moderately barbed, 8 setae in 1 st posthumeral row (C excluding humeral setae), by 6 setae in next two rows (D and E), four setae in 4 th row (F) plus 4–6 caudal setae; 4 sternal setae; 24–25 ventral setae; NDV = 55–56. Note. *—holotype, two paratypes, and one non-type specimen; **—holotype, two paratypes, and three non-type specimens. GNATHOSOMA (Fig. 11G–I). Cheliceral blade with tricuspid cap and row of 5–6 dorsal teeth; cheliceral base with sparse puncta; gnathobase with sparse puncta, transverse cuticular striations and one pair of branched gnathocoxal (tritorostral) setae; galeal (deutorostral) seta nude; palpal claw with three prongs; seta on palpal femur with one branch (visible only in one specimen); setae on palpal genu and tibia nude; palpal tarsus with 7 branched setae, subterminala (ζ) and tarsala (ω). SCUTUM (Figs. 10, 11C). Pentagonal, moderately covered with small puncta, anterior scutal margin slightly concave, lateral margins almost straight, posterior margin greatly projected, rounded; AM posterior to level of ALs; sensillary (trichobothrial) bases anterior to level of PLs (PSB – P-PL = 2–6), with curved anterior ridges; AM uniform with dorsal idiosomal setae, ALs and PLs covered with long thin barbs; AL> PL >> AM; sensilla (trichobothria) globose, covered with setules. LEGS (Fig. 11J–L). All 7-segmented, with 1 pair of claws and claw-like empodium. Leg I: coxa with 1 branched seta (1B); trochanter 1B; basifemur 1B; telofemur 5B; genu 4B, 3 genualae (σ), microgenuala (κ); tibia 8B, 2 tibialae (φ), microtibiala (κ); tarsus 21B, tarsala (ω), microtarsala (ε) distal to tarsala, subterminala (ζ), parasubterminala (z), pretarsala (ζ). Leg II: coxa 1B; trochanter 1B; basifemur 2B; telofemur 4B; genu 3B, genuala (σ); tibia 6B, 2 tibialae (φ); tarsus 16B, tarsala (ω), microtarsala (ε) behind tarsala, pretarsala (ζ). Leg III: coxa 1B; trochanter 1B; basifemur 2B; telofemur 3B; genu 3B, genuala (σ); tibia 6B, tibiala (φ); tarsus 14B, mastitarsala. Distribution and hosts. This species was described from Vumba and Chishawasha, Southern Rhodesia (currently Zimbabwe), ex Trachylepis varia (Peters) (syn. Mabuya varia) (Squamata: Scincidae). Here I report it from South Africa (Drakensberg Mts, Champagne Castle, KwaZulu-Natal Prov.) and ex Pseudocordylus subviridis (Smith) (Squamata: Cordylidae) for the first time. Material examined. Holotype, larva NM 4870, Vumba, S. Rhodesia, ex M. varia, February 1948, collector unknown (Fig. 1, 16). One paratype, larva NM 4870/2, same data (Fig. 1, 17). One paratype, larva deposited in NHM (1957-8-12 -35), same data (Fig. 1, 18). One larva NM 4870/3, Champagne Castle, Hostel, Natal (currently KwaZulu-Natal Prov.), ex P. subviridis, collector and date unknown (Fig. 1, 19). Remarks. The specimen of S. scincicola NM 4870/3 from Champagne Castle (Fig. 1, 19) and the specimen of S. monticola NM 4827 from Vumba (Fig. 1, 22) have an inscription “ paratype ”, but their collection data do not coincide with the original description and the identification labels seem not original. Probably, these specimens were re-identified and renumbered; therefore, I cannot regard them as true paratypes. I assume that the former initially belonged to the type series of S. monticola and the latter—to the type series of S. scincicola.
