Krutov. Total: 39 paratypes. FWL: holotype: 51mm Morphologically,  C. brykiis very similar to  C. scottiand  C. lineosa,but has a brighter green background with less prominent diagonal lines on the forewing upperside. The forewing ground colour is green (may be yellowishgrey, olive-grey or brownish-green in old or discoloured specimens) without the gradient in the green tone observed in  C. lineosa.The diagonal lines of the forewing upperside are weakly differentiated from the ground colour, with some, particularly the most distal one, barely visible, unlike  C. subangustatain which all eight dark green or brown diagonal lines are clearly visible. The outer edge of the black basal patch of the hindwing upperside extends along the veins. The female is similar to the male, but it is larger, with rounder forewings and with the black basal patch of the hindwing upperside with less pronounced sharp triangles extending along the veins. The structures of the male genitalia ( Fig. 21) are within the range of variation of both  C. lineosaand  C. scotti( Fig. 22–34) and are very different from those of  C. minorand  C. pollux( Fig. 35, 36). The uncus lacks an acute sclerotized hook ventrally; the sclerotized process of the harpe is elongate, almost the same width over the entire length; and the margin of the basal plate of the phallus armature is deeply denticulate with a large apical hook distally (the basal portion of this hook is angled at about 30° to the phallus main axis). In male genitalia of the superficially similar but larger  C. subangustata continentalis  ssp. n.(described below) ( Fig. 37), the uncus bears an acute tooth ventrally, the sclerotized process of the harpe is chunky, noticeably narrowing distally; and the phallus armature has a less denticulate plate and a short, small apical hook that is devoid of additional minute teeth on its surface (the basal portion of the hook is angled at about 45° to the phallus main axis). Generally,  C. brykihas thinner and more elongate male genital structures than  C. subangustata. One mtDNA haplotype of  C. brykiis shown in Fig. 40. It is common to all six examined specimens and the Chinese specimen found in the BOLDdatabase. The translated polypeptide sequence differs from the other  Cechetraspecies by one non-synonymic amino acid substitution. Examination of the “type” of  C. lineosaf. viridulaconvinced us that it is just a discoloured specimen of  C. bryki. Another moth, in NHMUK, was illustrated by d'Abrera ([1987]: p. 205-206) as a “green form” of  C. lineosa, but he did not give any locality data. We have examined this specimen, which proved to come from Sikkim, India, and found that it, too, is a specimen of  C. bryki. We have thus included both these specimens in the paratype series of  C. bryki. Overall, the current known range of  C. brykiencompasses areas in Northern India, Nepal, Myanmar, Southwestern Chinaand Northern Vietnamat altitudes above 1900 m. It might also reasonably be expected to occur in the mountainous areas of Bhutan, Laos, Northern Thailandand Cambodia. Currently, only one generation per year is known for  C. bryki, from the end of May until early August. The larval hostplants of  C. brykiare currently unknown. The hostplants of the closely related  C. lineosawerelisted by Bell & Scott (1937)as  Impatiens(Balsaminaceae),  Saurauia(Actinidiaceae),  Polygonum(Polygonaceae)and  Vitis(Vitaceae). All of these are members of early succession plant communities, which is typical for most hawkmoths of subfamily  Macroglossinae. This explains, for example, why  C. lineosais a very common species in anthropogenic and disturbed plant communities. Such early succession communities at higher altitudes are usually microniches in late successional forests, known in the phytocenological literature as “gaps”, emerging due to rock collapse, windfalls and similar disturbances. Ecologically,  C. brykiis likely to belong to the fauna of equatorial cloud forests and have a patchy distribution due to origin and lack of persistence of its habitats.   Etymology.The species is named after the Swedish entomologist, anthropologist and writer, Felix Bryk, who described  C. lineosaf. viridula. We decided not to use the unavailable infrasubspecific name viridulabut rather to propose a new name in accordance with the name availability criteria of the International Code of Zoological Nomenclature (ICZN 1999, 2012). 1914123400 1990-07-16 BMNH, NHMUK T.
