Diagnosis. Medium sized, chestnut brown species with very fine setae on scutellum, pronotum, and elytra (Fig. 8). Distribution centred in the Eastern and Western Cape of South Africa (Fig. 21).
Redescription. Size (n = 5 males; n = 5 females). Length: males, mean 17.8 mm, (range 17.0–19.0 mm), females, 19.0 mm, (18.0–21.0 mm). Width: males, 9.7 mm, (9.5–10.0 mm), females, 10.4 mm, (10.0–11.0 mm). Pronotum ratio 1.53:1 (n = 53); 1.51:1 (n = 5Ƥ). Colour (Fig. 8): Light chestnut brown to dark brown, with tan coloured setae. Head (Figs. 38–39, 52): Head clothed with very fine setae. Clypeus hardly reflexed in the middle, anterior clypeal margin concave and bowl shaped. Pronotum (Figs. 89–93): Pronotum covered with small setae; lateral margins clearly serrated, with irregular sized mostly blunt-ended teeth, stiff setae between teeth. Longer and finer setae along anterior and lateral edges. Scutellum (Figs. 108–109): Scutellum triangular, apex smoothly rounded and covered by fine setae within sculptured punctures. Elytra (Figs. 131– 133): Scales on the elytra are fine; with 4–5 denudate maculae on elytra. Pygidium (Figs. 148–149): Pygidium flat and setiferous. Male genitalia illustrated in Figs. 171–173.
Morphological variability. The specimens examined show little external difference, other than the light brown and darker brown forms. Since both colour forms are found at the same localities, this is regarded as intraspecific variation.
Distribution. Endemic to the Western and Eastern Cape Province, with most collection records being quite close to the coast (Fig. 21).
Old records from Port Natal (= Durban) and student records from Port Shepstone, Ellisras, and Harare (in Zimbabwe) are here interpreted to represent incorrect localities. There are no recent or corroborating records of A. subfasciata from KwaZulu– Natal, or beyond the coast of the Eastern and Western Cape of South Africa.
Conservation status. As an Eastern and Western Cape endemic, with the potential to become a sporadic pest of pineapples pre-plant pesticides are used in agro-ecosystems against this species. However, it remains an endemic species to South Africa requiring conservation.
Natural history and pest status. Refer to natural history under genus section. Asthenopholis subfasciata has been collected from September to May, with the main activity period from November to March (Fig. 180).
Remarks. Dr. Hartwig of the Plant Protection Research Institute and South African National Collection of Insects (SANC) identified the adults of the pineapple white grub species submitted by Mr. Graham Petty for identification (G. D. Petty, Agricultural Research Council, Institute for Tropical and Subtropical Crops, Bathurst, South Africa; personal communication 2007). Representatives of this species from both those deposited in the SANC, and new material provided by Petty confirms that the species referred to by Petty (1976, 1977b, 1978, 1982, 1990, 1994) as Asthenopholis subfasciata was correctly identified in accordance with the type specimens studied here.
