Diagnosis. The forewing length is 11.0–13.0 mm in males and 10.0–14.0 mm in females. In the male genital capsule, the new species differs from the sympatric A. tryphosa in the markedly more proximally swollen uncus, the dorsally broader arms of the tegumen, the subbasally concave dorsal margin of the valva (it is straight in A. tryphosa ), the more rounded editum-costa complex, and the shorter and basally broader proximal lobe of the distal saccular process, which is displaced distally, to the middle of the process. The phalli of the two species are very similar but in A. pervolgata sp. n. it has a somewhat broader coecum. The vesica of the new species is clearly different from A. tryphosa in the longer distal diverticulum with two small subdiverticula and bearing a cornutus apically whereas in A. tryphosa it is situated dorsally while the tip of the diverticulum is hook-like curved ventrad. The female genitalia of A. pervolgata sp. n. can be easily distinguished from A. tryphosa by the ventrally sclerotised ductus bursae (it is membranous in the congener), and the longer and broader sclerotised area of the posterior section of the corpus bursae, which is situated anteriorly and forms a belt around its entire circumference (vs. postero-lateral position in its congener). Additionally, the signum of the new species is slightly larger than in A. tryphosa .

Distribution. The new species is widely distributed from the Ziama Massif in the west to the western Congo Basin and north-western Zambia in the east and south-east, respectively, and is currently known from Guinea, Liberia, Ivory Coast, Nigeria, Cameroon, Gabon, Republic of Congo, DRC and Zambia. The species possibly reaches Uganda in the east (see above Remark under A. tryphosa tryphosa ) but clarification of the eastern limits of its range requires the examination of additional material.

Etymology. The specific epithet is derived from the Latin ‘pervolgo’ meaning ‘to publish’ and refers to the fact that after six decades of confusion with Flavifronthosia flavifrontella comb. n. a name for this species is finally published. The name is a participle in apposition to the genus name.
