Additional material examined

Mauritius. 1 female, Mt. Cocotte , on track on first big band, swampy woodland, 718m, 20°26’27”S, 57°28’34”E, 4.xii.2005, MV, leg. Clive R. Turner, gen. slide No.: LG 4085 ( ANHRT) GoogleMaps ; 1 female, “26. 21. Mauritius”, gen. slide No.: LG 4105 ( NHMUK) .

Taxonomic note. The taxon atrilunaria was described in the genus Boarmia but attributed to Hypomecis by Scoble (1999). Examinations of the external and genital morphology have suggested its correct assignment to Afroracotis . Due to minor morphological differences between incompletaria and atrilunaria , the latter taxon is downgraded here to subspecies rank.

Diagnosis. Forewing length 23–24 mm. Afroracotis incompletaria atrilunaria ( Mabille, 1893) is very similar to the nominotypical subspecies, but the forewing pattern is more strongly speckled with more contrasting transverse fasciae and a more sharply defined black discal spot on the forewing which is poorly visible in the other subspecies. In the female genitalia, the differences between the two taxa are limited, expressed only in the slightly shorter antrum and somewhat longer sclerotised distal section of the corpus bursae of A. incompletaria atrilunaria compared to the nominotypical subspecies from Réunion.

The male is unknown.

Genetic information. The specimens accessed during this study have not been sequenced due to their age.

Distribution ( Map 1 View MAP 1 ). This subspecies of A. incompletaria is endemic to Mauritius.
