Diagnosis

See diagnosis of next species. The female is larger than the male with slightly more produced forewing apices.

Taxonomic Notes

The wider relationships of Sundanian Narosa are described in the generic notes.

The Sulawesi species attributed to Narosa by Holloway (1987a) are related to the Sundanian species concinna Swinhoe and velutina Walker, both occurring in Borneo. The group also includes an undescribed species from Waigeu and pectinata Hering from New Guinea. A preliminary phylogenetic analysis (Holloway, 1987a) indicated that the Sundanian pair was sister to a grouping of all the more easterly species. This sister pair of clades in turn related to the Himalayan endodonta Hampson. Solovyev & Witt (2009) described a new genus, Caelestomorpha Solovyev & Witt, with type species albiceris Solovyev & Witt from Thailand, Cambodia and Vietnam, but included endodonta as a second species. Despite the strong and asymmetric development of the saccular processes of the valves in taxa from Sundaland eastwards, the valve shape and structure of the uncus and gnathus are as in the generic definition of Solovyev & Witt, and so all named taxa from this more eastern complex are transferred to Caelestomorpha: *C. concinna Swinhoe comb. n.; C. velutinacomb. n.**; C. pectinata Hering comb. n. None of the Sulawesi species has been described, but the phylogenetic analysis of Holloway (1987) was discussed further, with more ecological detail, in the context of speciation on Sulawesi by Holloway (1991).

Habitat Preference

The species is generally rare and probably restricted to the lowlands. It has been taken once at 300m in the Ulu Temburong, and severally in extensive mangrove by Sungei Kibi and S. Selanjak, Brunei.
