Remarks. 1. The male and female genitalia of malayana   ( Figs. 31–33 View FIGURES 31–33 , 40, 41 View FIGURES 37–42 ) have significant differences from those of C. bianca   ( Fig. 25–27 View FIGURES 25–27 , 37 View FIGURES 37–42 ). Therefore we treat this taxon as a good species and not a subspecies of C. bianca   . 2. The type series from Cameron Highlands has reduced black borders of the ante- and postmedial lines ( Fig. 11 View FIGURES 9–16 ), while the specimens from other parts of the species’ range north and south of Cameron Highlands have the well-developed black borders of the transverse lines ( Figs. 12–16 View FIGURES 9–16 ). Because of the absence of genital differences ( Figs. 31–33 View FIGURES 31–33 ), we treat this population as a local color form only. 3. The female paratypes of the species ( Fig. 42 View FIGURES 37–42 ) are not conspecific to the male holotype and paratypes and belong to Cyana determinata sausae Bucsek, 2012   described by males also from Pahang.

Diagnosis. Forewing length is 14.5– 18 mm in males and 19–20 mm in females. Externally, C. malayana   ( Figs. 11–16 View FIGURES 9–16 ) has no significant differences from C. bianca   ( Figs. 1–4 View FIGURES 1–8 ) and C. indosinica   sp. nov. ( Figs. 5–10 View FIGURES 1–8 View FIGURES 9–16 ). The male genitalia of C. malayana   ( Figs. 31–33 View FIGURES 31–33 ) differ clearly from those of C. bianca   ( Fig. 25–27 View FIGURES 25–27 ) in the rounded lateral lobes of the vinculum, the larger and more robust ampulla, the much larger medial posterior, medial anterior and distal diverticula, and the broader medial dorsal diverticulum; from C. indosinica   sp. nov. ( Figs. 28–30 View FIGURES 28–30 ) they differ in the significantly larger and more robust ampulla, the narrower medial posterior and distal diverticula, which have narrower fields of cornuti, the smaller medial anterior diverticulum, and the basally narrower medial dorsal diverticulum. The female genitalia of C. malayana   ( Figs. 40, 41 View FIGURES 37–42 ) differ from those of C. bianca   ( Fig. 37 View FIGURES 37–42 ) in the longer ductus bursae, the larger appendix bursae, the shorter and stronger rugose posterior sclerotized plate of the corpus bursae, the weakly sclerotized medial-lateral sclerotized band of the corpus bursae, and the much smaller signa; from C. indosinica   sp. nov. ( Figs. 38, 39 View FIGURES 37–42 ) they differ in the more weakly sclerotized and much less rugose posterior plate of the corpus bursae, and the presence of only two signa in the corpus bursae (while in C. indosinica   sp. nov. there are three signa in the corpus bursae).

Distribution ( Fig. 46 View FIGURE 46 ). South Myanmar ( Hampson 1900), South-West and South Thailand (provinces Kanchanaburi, Chumphon, Ranong and Nakhon Si Tammarat), Malaysia (Malay Peninsula), Indonesia (Sumatra Isl.).
