Type material. Holotype ( Figs 62 , 324 ): male, “ Uganda 1700m | Bwindi Impenetrable N.P. , / Cuckooland Lodge | 01°00'17''S, 29°43'06''E | 28–29.vi.2022. Naumann, S., | Ott, E., Schintlmeister, A., | Sulak, H. Leg. | ANHRT:2022.12” / “ANHRTUK | 00201307” / “Slide | AV6984 ♂ | A. Volynkin ” ( ANHRT).

Diagnosis. The forewing length is 10.5 mm in the male holotype. Siccia bwindi is externally largely different from the other members of the species-group and is most reminiscent of S. mago , from which the new species can be distinguished by the longer rami of the male antenna, the lack of the black subbasal spot on the forewing costa, and the larger and distinct spots in the cell and on the outer forewing margin. The male genital capsule of the new species is similar to that of S. kastanota but differs in the somewhat narrower valva and the distal saccular process. The phallus of S. bwindi is narrower than in S. kastanota and has a shorter and narrower dorsal carinal process. Compared to S. kastanota , the vesica of S. bwindi has a narrower lateral basal diverticulum bearing a trapezoidal and more finely serrulate plate with irregular margins whereas that of S. kastanota is semicircular and covered with larger spinules. Additionally, the vesica of the new species has a conical dorsal and a utricular ventral diverticula, and its distal diverticulum is distally broader.

The female is unknown.

Molecular data. Currently unavailable for this species.

Distribution. The new species is currently known only from its type locality in south-western Uganda.

Etymology. The specific epithet is derived from Bwindi Impenetrable National Park, the type locality of the new species. The name is a noun in the nominative singular in apposition.
