Diagnosis. Arciera meridiana sp. n., the south-east African sister species of A. grisea ( Holland, 1893), described from Gabon, is distinguished by the following features: externally, the new species has a reddish wing coloration compared to the rather pale brownish grey or slightly yellowish coloration of A. grisea . In the male genitalia, A. meridiana has a slightly shorter uncus with a more dilated, bifid distal section and considerably shorter, slightly curved, latero-distally pointed apical processes. The new species also displays more curved socii, a shorter, markedly broader tegumen, a slightly narrower valva and a considerably shorter and narrower sacculus. The phallus of the new species is noticeably shorter and thicker with a shorter subapical carina dent. The eighth sternite of A. meridiana is considerably broader, its distal processes are much shorter and its proximal processes are longer with noticeably deeper medial depression compared to those of A. grisea . We did not study the female of A. grisea , so comparative studies of the female genitalia cannot be addressed in this paper.
