Diagnosis. Scrobipalpa portosanctana is characterized by a dark brown forewing with an oblique black patch at 1/3 and other distinct black markings in the cell and apical area. Its forewing pattern is very similar to that of S. geomicta, but the latter is on average smaller. The male genitalia of S. portosanctana are characterized by the following combination of features: narrow, elongated tegumen and uncus; weakly sigmoid valva; long sacculus; and apically broad, obtuse saccus. Scrobipalpa geomicta differs in its straight valva, distally narrower sacculus and narrower vincular process. The female genitalia of S. portosanctana are distinguished by broad subgenital plates that are nearly connected medially, and well-developed anteromedial sclerites. Scrobipalpa geomicta differs in having a teardrop-shaped rather than subtriangular anteromedial depression, indistinct anteromedial corners of the subgenital plates, and a slenderer signum.
Biology. Larvae feed on Lycium europaeum L. and L. barbatum L. (Solanaceae) in the Palaearctic Region (Huemer & Karsholt 2010: 161). In South Africa larvae were recorded on Lycium ferocissimum Miers (= campanulatum E. Meyer ex C.H. Wright). Adults fly in September, November, March and May.
Distribution: Southern Europe, NW Africa, Near East (Huemer & Karsholt 2010: 160; Bidzilya et al. 2019: 48), South Africa.
Remarks. Gelechia chersophila was described from four specimens collected in Kalk Bay, South Africa. I was not able to get in contact with curator of Lepidoptera in SAM to study the male holotype of the species. However, the redescription of the species in Janse (1960: 236) and the figure of the male genitalia of the holotype (Janse 1960, pl. 42b) as well as the male genitalia of one of paralectotypes examined by me, leave no doubt to its conspecificity with S. portosanctana. The female genitalia of specimens from South Africa differ slightly from those figured by Huemer & Karsholt (2010: 494, fig. 95) in that segment VIII is longer and lacks an excavated lateral margin.
