No. : AV6749 ( ANHRT ) . Diagnosis . The forewing length is 5.5 mm in males and 6.5 mm in the female. Siccia nepa is externally reminiscent of S. grossagranularis and S. perigraphoides but distinguished by its markedly smaller size. In the male genital capsule, the new species differs from both the similar species in the broader valva with a strongly elongate and narrow process of the cucullus. The phallus of S. nepa is shorter than in the aforementioned congeners. The vesica shape of the new species is similar to S. perigraphoides but differs in the bilobate distal diverticulum (it is unilobate in the congener), and the presence of an additional conical diverticulum ventrally. The female genitalia of S. nepa are most similar to S. orbiculata but distinguished by the shorter apophyses anteriores, the posteriorly broader ductus bursae with a medial depression in the ventral margin of the ostium bursae, and the considerably broader corpus bursae having larger postero-lateral gelatinous protrusions. Molecular data . Currently unavailable for this species. Distribution . The new species is currently known only from coastal Ivory Coast . Etymology . The specific epithet refers to the shape of the valva of the new species, which is reminiscent of the raptorial foreleg of members of the aquatic Heteropteran family Nepidae . The name is a noun in the nominative singular in apposition.
