TL: South Africa . [SAMC]. Atrichozancla cosymbota ; Janse 1954: 369 ; Park & De Prins 2019: 64 ; Park et al . 2021: 356 . Material examined. South Africa : Holotype male ( Oudebosch , Jan. & Feb. ), in SAMC . Diagnosis. Wingspan 15.0 mm. See Janse (1954 : Pl. 157, fig. 5). Head, antenna, labial palpus, and leg pale yellowish-orange. Forewing glossy fuscous, with a few pale scales. The male genitalia of this species can be distinguished from those of E. gymnopalpa ( Janse, 1963 ) by the following traits: costa of cucullus convex medially (slightly concave in the latter), and not angulate on ventral margin. Janse (1954) noted that the male genitalia are also similar to those of A. phaeocrossis Meyrick, 1937 , but with the cucullus slender and the aedeagus devoid of small triangular processes on the upper surface. Male genitalia . See Janse (1954 : Pl. 152, fig. 6). Female unknown. Distribution . South Africa ( Western Cape ).
