Fynbosia unicaria Englund, Staude & Sihvonen 2026, sp. nov.

Fynbosia unicaria Englund, Staude & Sihvonen sp. nov. Type material. Holotype • ♂ (Figs 3 B, 3 D, 6 C), South Africa: Northern Cape, Calvinia, Hantamsberg, Van Rhynshoek, 33.377°S, 19.785°E, 1577 m, Renosterveld gonnabos, 31 Mar. 2022, leg. H. S. Staude, DNA sample ME 81, gen. prep. PS 2919, micro-CT scan MS 125, coll. Ditsong Museum of Natural History, Pretoria, South Africa. Diagnosis. Adult male F. unicaria sp. nov. distinguishable from F. horingaria sp. nov. based on the wing patterns and genitalia. Both fore- and hindwing medial lines sharply angled near costa, not evenly rounded as in F. horingaria sp. nov., best visible on the wing undersides. Discal spots suffuse, dark, streak-like in forewings (Figs 3, 6; Key 1). Male genitalia weakly sclerotized, but distinguishable from F. unicaria sp. nov. by the narrower valva and short, blunt saccus (Figs 6, 8; Key 2). Average mtCOI genetic distance to F. horingaria sp. nov. is 5 %. Description. Adults (male). Head: Frons and vertex covered with light brown scales, string of hair-like scales protruding at posterior margin of head, compound eye naked. Labial palpi extremely short, length less than 1 / 5 of eye diameter, oriented ventrally, hardly visible between eyes, proboscis vestigial, defunct. Male antenna (Figs 3 B, 3 D, 6 C) bipectinate, proximal third of flagella dorsally covered with dark brown scales, two distal thirds covered with ochraceous cells scattered with darker brown scales, ramus black, conspicuously long, length up to 1.5 times diameter of compound eye, abundant long cilia covering ramus. Thorax: Covered with brown scales of varying tone. Spur pattern on legs 0–0 – 2. Abdomen: Segments covered with brown scales of varying tone, mottled with blackish scales. Some long hair-like scales extending distally from proximal segments of male abdomen. Wings (Figs 3 B, 3 D, 6 C): Forewing triangular, elongated, narrow, costa and termen almost straight, tornus round, without distinct transition from termen to dorsum, wingspan 20 mm. Forewing ground colour grey-brown, medial and terminal areas darker than rest of forewing, postmedial line almost straight, bordered distally with broad, suffuse hazel brown margin, turning inwards at sharp angle before touching costa. Discal spot stripe-like, black. Hindwings echoing forewing ornamentation pattern in less pronounced manner; postmedial line sharply angled, discal spot small, round, black. Dark, suffuse blotches in terminal area. Genitalia: Male (Figs 6 D, 8 F – K): Genitalia generally weakly sclerotised and simple, except for the tip of gnathos. Few diagnostic features. Valva narrow, costa straight. Saccus short, borders almost straight, forming roughly right angle at tip. Aedeagus without well-sclerotised cornuti. Female and immature stages unknown. Genetic data. GenBank accession numbers PV 988411 – PV 988416. Etymology. Unicus (> Latin = sole, only); pertaining to the rarity and solitary known specimen of the species at the time of description.
