Ochthopetina transvaalensis (End.). 1909. Enderlein, Zool. Anz., vol. xxxiv, p. 402 (?). 1923. Klapalek, he. cit., p. 140, fig. 13 ($). 1931. Tillyard, loc. cit., p. 115, fig. 1 (part). Tillyard has mentioned the variability of the venation and other features. Enderlein's description of the VHIth sternite of $ is correct, viz. not differing from the other sternites, with straight hind margin and without sculpture. The appearance described by Klapalek is erroneous and due to shrinkage (I have examined the two specimens returned to the South African Museum with Klapalek's labels— Klapalek evidently did not relax either of them). ? <J Genitalia (fig. 4).—Vllth tergite with a slightly more strongly chitinised squarish patch bearing a median group of conical granules. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original South African Museum.
