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.
