Remark. The male genitalia of the specimens from Tanzaniaand Kenyadiffer from those of the specimens from South Africa, Malawi, Zambiaand western Ugandaby the slightly narrower vesica with a distal diverticulum bearing a smaller number of cornuti. To clarify the taxonomic status of these populations, molecular studies would be required.
Diagnosis. Forewing length is 12–16 mmin males, 11.5–14 mmin females. As the external appearance of Cyana cornutissima sp. n.is nearly identical with that of the sympatric C. yao sp. n., the examination of the genitalia is required for reliable identification. The male genital capsule of the new species differs from those of the other taxa of the species-group by the longer and narrower uncus. The vesica of C. cornutissima sp. n.differs clearly from those of the other species of the C. rejectaspecies-group by the considerably larger distal diverticulum bearing a markedly more extensive row of numerous long cornuti. The configuration of the diverticula of the vesica of C. cornutissima sp. n.is most similar to that of C. rejecta, but in C. cornutissima sp. n.the subbasal diverticulum is broader basally; the 1 stmedial diverticulum is larger, more elongate and more heavily scobinated; the 2 ndmedial diverticulum is smaller; the 3 rdmedial diverticulum is present (absent in C. rejecta), and the subdistal diverticulum is slightly smaller and more weakly scobinated compared to those characters of C. rejecta. The female genitalia of C. cornutissima sp. n.are easily distinguishable from those of its congeners by their conspicuously long ductus bursae (the longest in the species-group) with a weakly sclerotized lateral pocket anteriorly and heavily sclerotized longitudinal wrinkles deeply protruding to the basal part of the appendix bursae, the presence of a small, button-like signum bursae (as in C. occidentalis sp. n.), and the large, sack-like, heavily sclerotized appendix bursae, which is smooth distally and anteriorly (which is short, conical and weakly sclerotized in C. rejectaand C. yao sp. n.; whereas in C. occidentalis sp. n.the appendix bursae is globular and wrinkled all over its surface).
Distribution. Northern part of South Africa, Mozambique, Malawi, Zimbabwe, Zambia, Uganda, Tanzaniaand Kenya.
Etymology. In Latin, the suffix ‘-issimus’ expresses the superlative. The specific epithet refers to the conspicuously long and dense cornuti of the distal diverticulum of the vesica, the longest and most numerous among the species of the C. rejectaspecies-group.
