Type material. Holotype ( Figs 5 View FIGURES 1–8 , 29 View FIGURES 29–32 ): ♂, “ VIII.2015, Central Vietnam, Da Nang Province, Ba Na Mt. , leg. Le Luong Thanh ”, slide AV2302 ♂ Volynkin (Coll. NHMUK).  

Paratypes: 1 ♂, same data as in the holotype, slide AV2297 ♀ ( Coll. CAV)   ; 1 ♂, 8 ♀, same locality and collec- tor, IX.2015, slides AV1703 ♂, Volynkin (Coll. CAV)   ; 2 ♂, VIII.2016, Central Vietnam, Thua Thien-Hue Province, Annamite Mts., Bach Ma Mt. , 1400m, leg. Le Luong Thanh (Coll. CAV)  

.

Diagnosis. Forewing length is 14–14.5 mm in males (14.5 mm in the holotype) and 17.5 mm in females. Cyana titovi   ( Figs 5, 6 View FIGURES 1–8 ) is similar externally to C. aurantifascia   ( Figs 7, 8 View FIGURES 1–8 ), but differs clearly by its smaller size and smaller black spots on forewing. The male genital capsule of the new species ( Figs 29, 30 View FIGURES 29–32 ) is similar to that of C. aurantifascia   ( Figs 31, 32 View FIGURES 29–32 ), but has slightly more convex costal margin of valva. The vesica of C. titovi   differs from that of C. aurantifascia   by the much smaller largest diverticulum, the broader 1 st distal diverticulum bearing a broader cluster of much more robust spinules, and the smaller 2 nd distal diverticulum. The female genitalia of C. titovi   ( Fig. 39 View FIGURES 37–42 ) can be distinguished from those of C. aurantifascia   ( Fig. 40 View FIGURES 37–42 ) by the slightly longer ductus bursae, the larger signum bursae, and the narrower and twisted distal membranous section of appendix bursae (that is broad and globular in C. aurantifascia   ).

Distribution. Central Vietnam (Da Nang Province).

Etymology. The species name is dedicated to Dr. Sergey V. Titov (Pavlodar, Kazakhstan), an expert in Central Asian Noctuoidea and friend of senior and fourth authors of the present paper.
