Isomyia borneensis (Peris 1951)

Isomyia borneensis (Peris)

Thelychaeta borneensis Peris, 1951, p. 247.

This species was described (Peris, 1951) and redescribed in more detail (Peris, 1952) from a single female, erroneously stated to be a male in the type citation in the second work. I have seen six specimens which conform with Peris’ descriptions for the most part; the femora, described as metallic green or violet, are variable as to the extent of that color; and the abdomen is distinctly pollinose dorsally, at least in large part, if viewed at an angle. New records are: 2, 1, Borneo, Kupat, 7–15, September 1927, British Museum (Natural History); 2 , Borneo, Bettotan, 18 August 1927, British Museum (Natural History); 1 , Sumatra, Fort de Koch, 920 meters, 1925, E. Jacobson, Amsterdam Museum.

A considerable residue of material, forming, along with I. delectans, I. pictifacies, and I. electa, a part of the delectans complex, must await further study after accumulation of more material.
