( ANHRT ) . Diagnosis . The forewing length is 6.0 mm in the male holotype . Siccia comma is externally reminiscent of S. mayombe but distinguished by the somewhat larger size, the broader forewing with a more convex costal margin and a more elongate apex, the paler, brownish-grey forewing ground colour (it is pale brown in the congener), the larger and comma-shaped discal spot of the forewing (it is circular in S. mayombe ), the somewhat larger subapical spot at the costal margin, and the somewhat more greyish hindwing. In the male genital capsule, the new species differs from S. mayombe in the distally narrower uncus, and the somewhat narrower valvae with thinner and slightly downcurved cuculli (they are almost straight in the congener). The phallus of S. comma is less anteriorly dilated than in S. mayombe , and its distal section is more laterally curved. Compared to S. mayombe , the vesica of S. comma is somewhat shorter and narrower, the dorsal diverticulum bears a shorter cornutus laterally, the subbasal diverticulum is narrower, and the distal diverticulum is proximally narrower. The female is unknown. Molecular data . Currently unavailable for this species. Distribution . The new species is currently known from north-eastern Republic of the Congo . Etymology . The specific epithet refers to the characteristic comma-shaped discal spot on the forewing of the new species. The name is a noun in the nominative singular in apposition.
