Siccia chilambwe is externally reminiscent of S. atriguttata having fundamentally different genitalia in both sexes but distinguished by the somewhat broader forewing with larger black spots on costal and outer margins. The male genital capsule of the new species is most similar to the externally dissimilar S. foya but differ in the larger medial thorn of the medial costal process, and the more robust cucullus bearing markedly larger claw-shaped apical processes. The phallus of S. chilambwe is somewhat longer than in S. foya (in proportion to the tegumen-vinculum complex). Compared to S. foya , the vesica of the new species is broader and has an additional utricular medial-distal diverticulum. The female genitalia of S. chilambwe are most similar to S. ziela and the detailed comparison is provided above in the diagnosis of the latter species. Molecular data . The intraspecific divergence of COI-5P sequences calculated from five specimens is in the range of 0.00–1.71%. The nearest neighbour of S. chilambwe is S. foya differing by 2.35–4.14%. Distribution . The new species is known from Zambia , Cameroon , Uganda and western Kenya . Etymology . The specific epithet is homonymic of the type locality of the new species, Chilambwe Falls. The name is a noun in the nominative singular in apposition.
