Thacona smithi László & Schintlmeister sp. n. (Figs. 4–5, 108)

Holotype. Male, “ Mozambique, 22m, Maputo Special Reserve, West Gate, (Sand Thicket), 26°30’14.2”S, 32°42’59.6”E, 3–13.XII.2016. MV. Aristophanous, M., Cristóvão, J., László, G., Miles, W. leg. ANHRT: 2017.22”; unique number: ANHRTUK 00083849, gen. slide No.: LG 5324 (ANHRT).

Paratype. 1 male, same locality and collectors as in the holotype but 21-30.XI.2016, ANHRT: 2017.22, unique number: ANHRTUK 00011052 (ANHRT) .

Diagnosis. The new species is reminiscent of Thacona stictica (Hampson, 1910) but is considerably smaller in size (by approximately 30%) and has a less contrasting wing pattern, without reniform stigmata. The male antennae of T. smithi sp. n. are filiform with fine ciliation, whereas they are bipectinate with short rami in T. stictica . Despite the external similarity of these two species, the configurations of their male genitalia are quite different. The new species has a markedly wider, distally dilated uncus with a short medio-apical depression, a much shorter tegumen and a ventro-medially dilated valva, which is evenly narrow along its length. The digitus processes are considerably shorter, apically pointed, the juxta is inverted-triangular and the phallus of the new species is somewhat shorter, distally slightly curved with a rather thick, straight coecum penis. The vesica bears a small area of granulation basally. The sclerotized plate of the eighth sternite of T. smithi is considerably smaller, more quadrangular with longer anterior processes than in T. stictica .

The female is unknown.
