Diagnosis. Forewing length is 16–19 mm in males and 19–21 mm in females. Externally, C. indosinica  sp. nov. ( Figs. 5–10View FIGURES 1–8View FIGURES 9–16) has no significant differences from C. bianca  ( Figs. 1–4View FIGURES 1–8) and C. malayana  ( Figs. 11–16View FIGURES 9–16) and can be distinguished by the genitalia. The male genitalia of C. indosinica  sp. nov. ( Figs. 28–30View FIGURES 28–30) are most similar to those of C. malayana  ( Figs. 31–33View FIGURES 31–33), but differ in the significantly smaller and weaker ampulla, the broader medial posterior and distal diverticula, which have broader fields of cornuti, the larger medial anterior diverticulum, and the basally broader medial dorsal diverticulum. The female genitalia of C. indosinica  sp. nov. ( Figs. 38, 39View FIGURES 37–42) differ from those of C. malayana  ( Figs. 40, 41View FIGURES 37–42) in the more heavily sclerotized posterior plate of the corpus bursae, which has stronger wrinkles, and the presence of three signa in the corpus bursae (while in C. malayana  there are only two signa).

Distribution ( Fig. 46View FIGURE 46). North and Central Thailand (provinces Chiang Rai, Chiang Mai, Nan, Saraburi, Nakhon Ratchasima), SW China (Yunnan), Laos (provinces Khammouan and Champasak), Cambodia (province Pursat) ( Bayarsaikhan & Bae 2016), Central and South Vietnam (provinces Da Nang and Lam Dong).

Etymology. The specific epithet refers to its geographical range located within the Indochina Peninsula.
