Xestomyza sp. A

One female specimen seen probably represents a new species of Xestomyza . As this specimen is in relatively poor condition and the male remains unknown, I do not describe it here, pending discovery of additional material. The small size, sparse setae and pubescence of the frons and most of the body, place it closer to X. stuckenbergi sp. n., while the flagellomere shape is more similar to X. lugubris . It differs from X. stuckenbergi sp. n. in several characters, including weakly developed dc setae, a short scape, a shiny spot on the anepisternum and anepimeron, and clear wings. As the male remains unknown, several important characters of the male terminalia cannot be determined. There is the possibility that this species may belong to the genus Braunsophila , or is intermediate between the concepts of these two genera.

Material examined: SOUTH AFRICA: Northern Cape: 1♀ 30 km W Calvinia [31°29'S 19°29'E], 7.ix.1983, A. Freidberg (MEI 123301, TAU) .
