Diagnosis. A. pallescens  ( Figs 6–8View FIGURES 1–11) resembles externally to A. rivulosa  ( Figs 4, 5View FIGURES 1–11), but can be distinguished by its darker coloration, wider and larger wing pattern elements, and much broader, almost straight medial line. The male genitalia of A. pallescens  ( Figs 15, 16View FIGURES 15–17) differ from those of other congeners by its much larger distal costal process, larger distal membranous lobe of valva, and bilobate distal saccular process. It is worth to mention that bilobate distal saccular process is present also in A. hieroglyphica ( Bethune-Baker, 1911)  ( Fig. 17View FIGURES 15–17), but its lobes are much larger.

Re-description. Adult ( Figs 6–8View FIGURES 1–11). Forewing length 9.5–10 mm in males and 10–10.5 mm in females. Antennae of both sexes ciliate, with longer ciliae in males. Head brownish orange with a black dot on frons; thorax brownish orange with two black dots medially and two black dots on tegulae; abdomen brownish orange with admixture of ochreous scales. Forewing ground color brownish orange, pattern blackish brown, encircled by red scales. Discal spot dot-like. Subbasal line represented by a large dot. Antemedial line double, wavy, its outer line interrupted. Medial line very broad, irregularly dentate, slightly oblique. Postmedial line shortly dentate at veins, loop-like curved opposite the cell. Subterminal line interrupted, represented as a dentate row of dots on veins. Cilia brownish orange. Hindwing pale orange ochreous, without pattern. Male genitalia ( Figs 15, 16View FIGURES 15–17). Uncus narrow, long, medially curved, apically pointed. Tuba analis broad, membranous; scaphium thin, weakly sclerotized; subscaphium absent. Tegumen short and narrow. Juxta narrow, shield-like, with trigonal inner groove. Vinculum heavily sclerotized, V-shaped, with rounded tip. Valva elongate and relatively narrow. Costa curved medially, with long, sclerotized, claw-like distal process. Sacculus moderately broad, weakly setose, its distal saccular process short, heavily sclerotized, with an additional trigonal dorsal process subapically. Distal membranous lobe of valva relatively short, broadly rounded, longer than distal saccular process. Aedeagus elongate, straight, slightly tapering distally. Vesica relatively thick, with two short membranous diverticula laterally, a trilobate granulated diverticulum latero-dorsally, and a large, basally curved blade-like cornutus apically. Female genitalia ( Figs 20, 21View FIGURES 18–23). Papillae anales rectangular with rounded corners. Apophyses long and thin, apophyses anteriores slightly longer than apophyses posteriores. Antrum broad, almost rectangular, slightly convex posteriorly. Ductus bursae very short, slightly narrower than antrum, membranous. Corpus bursae broad, globular, strongly granulated, with a broad and elongate sclerotised area dorsally, a broad V-shaped posterior plate covered with short, but robust spines, and two very large, heavily sclerotized lateral signa covered with robust spines. Appendix bursae large, sack-like, situated latero-posteriorly, membranous, with a small granulated field distally.

Distribution. The species is widespread in West and Central Africa (recorded from Guinea ( Durante 2009), Togo, Cameroon, Zambia and Rwanda).
