Klícha, Miroslav & Wiesner, Jürgen, 2021, Taxonomic revision of Cosmodela duponti (Dejean), Cosmodela barmanica (Gestro), new status, and Cosmodela indica (Fleutiaux), new status (Coleoptera: Cicindelidae), Insecta Mundi 2021 (879), pp. 1-9 : 7

Key to distinguish Cosmodela duponti , C. barmanica and C. indica

1. Genae glabrous, the sutural and marginal iridescent bands not fully developed, the lateral bands are narrow and irregular, the widest part of the lateral band is situated at mid elytra; aedeagus slender, behind the bulge obliquely tapering to the mildly rounded apex.... Cosmodela duponti (Dejean)

— Genae setose, the sutural and marginal iridescent bands fully developed, the lateral bands make a regular wide line from the humera to the elytral apex; aedeagus robust, apex bluntly rounded.......... 2

2(1). Robust species, total length 17–19 mm; sutural and marginal bands bright deep green, sometimes with golden reflections; elytra slightly widened posteriorly, curved at the apex towards the sutura, in ♀♀ the curve is slightly waved; basal part of aedeagus regularly curved toward the top of the aedeagus, the line behind the step is short and horizontal up to a beak-like bend, aedeagus approx. 5.2 mm long...................................................... Cosmodela indica (Fleutiaux)

— Slender species, total length 13–17 mm; sutural and marginal bands with a brighter, lighter green colour, often with a hint of red (in some specimens from Myanmar and western Thailand the red hue may be prevailing, thus resembling the specimens of Cosmodela duponti from Vietnam); elytra parallel, gradually curved at the apex towards the sutura, in ♀♀ the curve is slightly waved; basal part of aedeagus slightly bevelled toward the top of the aedeagus, the line behind the step descends slightly up to a beak-like bend, aedeagus approx. 4.5 mm long.......... Cosmodela barmanica (Gestro)
