Etymology. In ancient Greek mythology, Atlanteia is one of Hamadryad nymphs, who consorted with Danaus, the king of Libya.

Diagnosis. Forewing length is 11–12.5 mm in males. Cyana atlanteia   is a closest relative of C. chrysopeleia   and C. intercomma   . It differs externally from C. chrysopeleia   by its smaller size and broader ante- and postmedial lines. The new species differs from C. intercomma   by its slightly smaller size, amber yellow forewing pattern (that is darker, apricot orange in C. intercomma   ), and pure white hindwing in male (whereas in male of C. intercomma   the hindwing is pale ginger orange). The male genitalia of C. atlanteia   differ from those of C. chrysopeleia   by their broader uncus, slightly narrower valva with a less developed medial costal crest, and the absence of spinules on the medial diverticulum. Compared to those of C. intercomma   , the male genitalia of C. atlanteia   have the longer uncus, the aedeagus without subapical dentate ring, the vesica bearing no spinules subbasally and distally, and the shorter dorsal diverticulum with a small subbasal subdiverticulum and only several spinules on its tip (whereas in C. intercomma   the dorsal diverticulum is longer, has no subdiverticulum and bears more numerous and robust spinules on its tip, and the vesica has a subbasal bunch of spinules and a long distal cluster of spinules stretching from the medial part of vesica to the base of the vesica ejaculatorius).

The female is unknown.

Distribution. The new species is up to date, known from South and North East India (Tamil Nadu and Assam).
