Perixera roseofusa Warren comb. rev.

Perixera roseofusa Warren, 1896, Novit. zool., 3: 376.

Diagnosis

The holotype is reddish in tone but the only other specimen seen has facies more as in the next two species, with fasciation on a yellowish fawn ground. The ground colour is slightly less yellow and the zig-zag postmedials somewhat more regular in course: both specimens are illustrated. Dissection of the genitalia is recommended for reliable identification.

Taxonomic notes

The male fourth sternite and the base of the genitalia have coremata. The distal process of the former is as described for ochraria and the related new species below, indicating that they form a natural group. There is a further, undescribed, species in the complex from New Guinea (slide 18484). The aedeagus is convoluted, with a strong cornutus in the vesica as in the next two species. The valves are bilaterally asymmetric, with strong costal ornamentation. The uncus is represented by two spines. The hind-tibia is very short but not tufted. A female from G. Kinabalu with a strong deep pink suffusion was suggested to belong to roseofusa by Prout (1938, Gross-Schmett. Erde 12: 179), but its genitalia (Fig 103) are unlike those of close relatives such as P. ochraria Swinhoe. Its identity is unresolved.

Geographical range

Borneo.

Habitat preference

The holotype is from the G. Mulu area but without precise altitude data. The second specimen is from a Gmelina arborea plantation at Brumas in the lowlands of Sabah.
