Bosara refusaria Walker comb. n.  
Acidalia refusaria Walker, 1861, List Specimens lepid. Insects Colln Br. Mus., 35: 1693.

Bosara refusaria (x 1.47)

Diagnosis. The species resembles a very small Glaucoclystis Gen. n. , but with the postmedials only slightly angled, more central, represented as a boundary between paler grey diffusing away distad and darker grey diffusing basad, the latter strongest at the angle on the forewing.

Taxonomic notes. The male abdomen has well-developed octavals, with basal and subapical cross-bars between them. They are exteriorly swollen between these, and apically rather spatulate. The genitalia resemble those of Bosara, but the tegumen is not expanded, the uncus moderate. The valves have only a hint of a process at the distal end of the saccular margin. The aedeagus is relatively long with, when uneverted, a short distal cornutus and a long basal one in the vesica. The female has a short ductus, flanked on the lamella antevaginalis by a pair of semicircular lobes (presumably for engagement with the octavals). The bursa has a long, fluted, sclerotised neck that contains several rows of robust spines, and a small, globular, immaculate bulb distally.

B. minima Warren comb. n. (Queensland, New Guinea, Bismarcks, Solomons) has genitalic features closer to those of typical Bosara though in facies it is almost identical to refusaria. The octavals not modified to the extent of those of refusaria, and the aedeagus cornuti are smaller. The female has a long, rather trumpet-shaped ductus and bursa, the former sclerotised without fluting or spines, the latter globular with general spining. In Sri Lanka there flies a third, undescribed member of the group (slide 19089). The taxon maculilinea Warren (Key Is.) is placed as a synonym of refusaria within Gymnoscelis in the BMNH arrangement. It is not conspecific and is probably best retained within Gymnoscelis until more material is available: it is represented by only the holotype female.

Geographical range. Borneo, Bali, Philippines.

Habitat preference. Four specimens have been taken in recent surveys, three in lowland dipterocarp forest (at 300m in Ulu Temburong, Brunei, and at 945m on G. Monkobo, Sabah) and one in secondary forest on the coast at Seria, Brunei.
