Genus Rubrindiania Volynkin & Huang, gen. nov.

https://zoobank.org/ urn:lsid:zoobank.org:act:02A9F785-A02B-4C30-97BB-20F96ED0CAC2 ( Figs 92, 93 , 152 , 206 )

Type species: Miltochrista cardinalis Hampson, 1900 .

Etymology. The generic name is a combination of the Latin word ‘ruber’ meaning ‘red’ and the generic name of the new genus’ closest relative Indiania . Gender feminine.

Diagnosis. Small moths with narrow and elongated wings with rounded apex. Forewing crimson, with a longitudinal black stripe broadened distally; hindwing blackish, semi-hyaline at base. Male is significantly smaller than female, with strongly ciliate antenna, whereas female antenna is weakly ciliate. The male genitalia are characterised by the combination of the following features: (1) the valvae are slightly asymmetrical: the right one is somewhat broader than the left one; (2) the valva is elongated, narrow basally and broadened distally, entire, with the costal margin being convex distally and having a small fold medially; (3) the medial costal process is very small, tubercle-like; (4) the distal costal process is thorn-like, situated at valva apex; (5) the sacculus is narrow, its distal process reduced to a small blunted protrusion; (6) a distal membranous lobe of valva is absent; (7) the aedeagus vesica is globular with several small diverticula, membranous, with a field of short stout cornuti (similar to that of Ammatho ). The male genitalia of Rubrindiania are similar to those of Indiania due to the slightly asymmetrical valvae with elongated and robust distal processes and the absence of a distal membranous lobe, but differ by the presence of a tubercle-like medial costal process, smaller distal costal processes, and the presence of small stout cornuti in aedeagus vesica (whereas in Indiania vesica bears patches of spinules or spine-like cornuti). The female genitalia of Rubrindiania are characterised by the combination of the following features: (1) the heavily sclerotised antrum with a trigonal medial concavity, connected with the 7 th abdominal sternite by a weak membrane (whereas in Indiania an antrum is absent, but an antevaginal plate is present); (2) the broadened and strongly rugose posterior section of corpus bursae (in Indiania that is narrowed and weakly sclerotised on the left and strongly scobinated on the right); (3) the membranous anterior section of corpus bursae bearing a double rugose signum (in Indiania the anterior section of corpus bursae is evenly scobinated and has no signum); (4) the appendix bursae is narrow, conical, rugose basally (in Indiania that is large, hook-like curved distally, with broad fields of robust scobination).

Distribution. The genus is distributed in northeastern India and northern Indochina.

Number of species. The genus comprises one valid species subdivided into two subspecies.
