Siccia salonga Volynkin, Saldaitis & Müller, sp. nov.

(Figs 5, 33)

Type material. Holotype (Figs 5, 33): male, “ DRC /Congo | Salonga National Park | S002°45'22.79''; E020°18'55.56'' | Ekongo Camp January 2017 | VD Kravchenko & GC Müler [leg.]” / “Slide | AV8720 ♂ | A. Volynkin” (USTTB, ex GMF-B).

Note. Belongs to the S. foya Volynkin, 2023 species-group established by Volynkin (2023).

Diagnosis. The forewing length is 6.5 mm in the male holotype. Siccia salonga sp. nov. (Fig. 5) is morphologically similar to S. foya Volynkin, 2023 (Fig. 6) but differs superficially in the somewhat darker forewing ground colour with larger and more distinct markings, and the markedly darker, blackish-brown hindwing ground colour, which is pale greyish-brown in S. foya . In the male genital capsule, the new species (Fig. 33) is distinguished from S. foya (Fig. 34) by the medially narrower uncus, the broader valva with a considerably narrower lobe of the editum bearing a thumb-shaped medio-ventral process (it is broad, triangular and with a spike-shaped apex in S. foya), and the shorter cucullus with equally long hook-shaped processes (they are unequal in S. foya). The phalli of the two species are alike. Compared to S. foya, the vesica of S. salonga sp. nov. has a proximally broader but shorter main chamber with a broader proximal and a shorter distal diverticula.

The female is unknown.

Distribution. Central Congo River basin (DRC) (Salonga National Park).

Etymology. The specific epithet is derived from Salonga National Park, where the new species is found. The name is a noun in the nominative singular in apposition.
