Treatment

Siccia bomassa Volynkin , sp. nov.

( Figs 1 View FIGURES 1–9 , 27 View FIGURES 27–30 )

Note. Belongs to the S. atriguttata Hampson, 1909 species-group established by Volynkin (2023).

Diagnosis. The forewing length is 8.0 mm in the male holotype. Siccia bomassa sp. nov. ( Fig. 1 View FIGURES 1–9 ) is superficially very similar to S. grossagranularis Kühne, 2007 ( Fig. 2 View FIGURES 1–9 ) and identification requires the examination of the genitalia structures. The male genital capsules of the two species are similar ( Figs 27–30 View FIGURES 27–30 ) but in S. bomassa sp. nov. the uncus is shorter and thinner, the valva is proximally broader, and the apical process of the cucullus is more distally tapered than the corresponding structures of S. grossagranularis . Unlike in S. grossagranularis , the phallus of S. bomassa sp. nov. has a longer and broader coecum and a somewhat more dilated distal section. The vesica of the new species differs from S. grossagranularis in the smaller ventral subbasal diverticulum bearing finer graniculi, and the basally narrower, dorsally elongate and conical distal diverticulum bearing a cluster of fine graniculi distally, whereas in S. grossagranularis it is semiglobular bearing a broad cluster of robust graniculi on its outer side.

The female is unknown.

Distribution. Northern Republic of Congo (Nouabalé-Ndoki National Park).

Etymology. The specific epithet is derived from the type locality of the new species, Bomassa camp in Nouabalé-Ndoki NP. The name is a noun in the nominative singular in apposition.
