Cyana spp. : A) Holotype male of C. pseudojavanica sp. nov. , Thailand; B) male of C. javanica , Flores Island, Indonesia. Scale bar = 5 mm. Photos: Vitaly M. Spitsyn. Diagnosis. The novel species is morphologically similar to Cyana javanica (Butler, 1877) and Cyana conclusa (Walker, 1862) , but can be distinguished from those taxa by a broad distal section of the valva (vs narrow and long distal section of the valva in C. javanica ) and by the lack of a cluster of spines in the aedeagus vesica (vs the presence of such cluster in C. conclusa ).
