Abstract: Schoengastia gerrhosauri Lawrence, 1949 (Fig. 15A) Schoengastia gerrhosauri Lawrence, 1949: 426, fig. 13; Wharton & Fuller 1952: 88; Vercammen-Grandjean 1958b: 659, pl. 9; Stekolnikov 2018: 78. Schoengastia (Schoengastia) gerrhosauri: Zumpt 1961: 155; Vercammen-Grandjean 1965b: 81. Diagnosis. AL> PL >>AM; fD = 2H-9-6-6-4-2-2; DS = 31; V = 24; NDV = 55; scutum pentagonal, with moderately projected posterior margin nearly straight in middle; sensillary bases slightly anterior to level of PLs (by 2 µm); Ip = 787. Standard measurements are given in Table 6. Distribution and hosts. This species was described from (1) Kranskop, Natal (currently KwaZulu-Natal Prov., South Africa), ex Gerrhosaurus flavigularis Wiegmann (Squamata: Gerrhosauridae); (2) Weenen, Kranskop, and Pietermaritzburg, Natal, ex Trachylepis striata (syn. Mabuya striata); (3) Muller’s pass, Newcastle, Natal, ex Pseudocordylus subviridis. Material examined. One paratype, larva deposited in NHM (1957-8-12 -36), NM 4833, ex G. flavigularis, Kranskop, collector and date unknown (Fig. 1, 24). Remarks. I was unable to examine gnathosoma and legs of the paratype, which I found in NHM; thus, I give here only measurements and a photography of the scutum. The single non-type specimen deposited in NM was found unsuitable for examination. Schoengastia gerrhosauri differs from S. monticola in a shorter scutum (ASB 27 vs. 30–33, SD 54 vs. 58–62), shorter PL (43 vs. 48–54), shorter dorsal idiosomal setae (H 38 vs. 40–47, D min 25 vs. 29–36, and D max 31 vs. 38–44), and shorter legs (Ip 787 vs. 889–913). Examination of new materials would add more diagnostic characters.
