Idiopteryx discopuncta (Janse, 1954) Park & Prins, 2019

Park, Kyu-Tek & Prins, Willy De, 2019, A review of the Lecithoceridae (Lepidoptera: Gelechioidea) of southern Africa, based on type specimens deposited in the Ditsong National Museum of Natural History (TMSA), with descriptions of three new species, Zootaxa 4623 (1), pp. 61-89 : 79

Idiopteryx discopuncta (Janse, 1954) , comb. nov.

( Figs. 7C , 8 D–F)

Isotypa discopuncta Janse, 1954: 383 . TL: Pietersburg, N. Transvaal [Limpopo], South Africa. [TMSA].

Adult. ( Figs. 7C , 8G ). See also Janse (1954, Pl. 169, Fig. 4 ). Wingspan 23 mm.

Diagnosis. This species can be distinguished by the more elongate forewing, with the costa concave medially, antemedian band more oblique, and the subterminal band narrower, nearly bent in S-shape, broadest near costa. The forewing venation is illustrated in Fig. 8G ; see also Janse (1954, Pl. 166, Fig. 1 ).

Male genitalia: see Janse (1954, pl. 188, Fig. 7 - line drawing; pl. 192, Fig. 1 -photo). Similar to those of I. bivia , but can be distinguished by the valva with more concave costal margin and the more broadly rounded apical area.

Female genitalia ( Fig. 8D ). Antrum large, cup-shaped, weakly sclerotized. Ductus bursae long, nearly twice the length of corpus bursae; corpus bursae ovate; signum with two mirrored, nearly symmetrical anterior and posterior plates of which the posterior one is much larger, separated by a broad medial ridge, which is much less sclerotized.

Material examined. Type no. 3410, ♂ (lectotype, designated here), gen. slide no. 2369. Paralectotype, type no. 3411, ♂, Johannesburg, 22–23 i 1965, L. Vári, deposited in TMSA, Fig. 7C . An additional female specimen: Jonkershoek, 22–23 x 1965, L. Vári, gen slide no. CIS-7180/Park .

Distribution. South Africa (Gauteng, Limpopo) (Janse 1954).

Remarks. The female is reported here for the first time, illustrating its genitalia, since it was described. Janse (1954) described the genus Isotypa , separating from the genus Idiopteryx , by the forewing venation lacking R 5 (Janse 1954, Pl. 166, Fig. 1 ), but it was due to mis-reading. R 5 on the forewing of this species which is well developed.
