Remark. In the original description, Walker (1869) did not mention a number of specimens, therefore the existence of syntypes is probable. Butler (1877) described Bizone pallens based on a series of specimens from several localities. To avoid any confusion in the future, here we designate the specimens deposited in the NHMUK collection and labeled as “Type”s as lectotype.

Diagnosis. Forewing length is 10.5–11 mm in males and 11.5–12.5 mm in females. The species varies in its size and width of forewing transverse lines. Nevertheless, its male genitalia are uniform throughout its range. Male of C. quadrinotata resembles externally that of C. dudgeoni , but differs by its smaller size, more rounded forewing apex, and S-like curved antemedial line (that is straight in C. dudgeoni ). Female of C. quadrinotata is very similar to that of C. catorhoda , and differs by its slightly S-like curved postmedial line. The male genital capsule of C. quadrinotata resembles that of C. catorhoda , but differs by the presence of lateral lobes of vinculum, and the broader valva with shorter distal section. The aedeagus of C. quadrinotata is slightly longer and narrower in C. catorhoda . The vesica of C. quadrinotata differs clearly from that of C. catorhoda by the long, narrow and granulated dorsal diverticulum (whereas in C. catorhoda the dorsal diverticulum is broad and globular and bears a broad cluster of spone-like cornuti), and the presence of a distal cluster of spine-like cornuti (absent in C. catorhoda ). The female genitalia of C. quadrinotata differ from those of C. catorhoda by the laterally prominent sclerotized posterior section of corpus bursae, and the presence of only signum surrounded by an area of granulation (whereas in C. catorhoda there are one round and one band-like signa).

Distribution. North East India (Sikkim, West Bengal, Assam, Meghalaya, Nagaland, Mizoram, Arunachal Pradesh) ( Hampson 1900; Singh et al. 2014, partly as alborosea ), Nepal, Bhutan, Bangladesh, Myanmar, S China ( Fang 2000, as C. alborosea ), Thailand ( Černý & Pinratana 2009, also as C. alborosea ), Laos, Cambodia, Vietnam, Malaysia (Malay Peninsula), Indonesia (Java) ( Bucsek 2012, partly as C. alborosea ).
