Mesa hyloides nov.sp.

H o l o t y p u s - Zaire = / Belgian Congo Beni Ituri Forest IX.1946 / BMNH.

figs 198-200. Body size = 19 mm.

Black and oranged yellow.

Oranged yellow: The whole of the head but temples, genae, ocellar area, lateral clypeal disk, base of mandibles; foretibia and tarsus. Wings strongly darkened. cOc complete. Pronotal plate with densely packed small p. N 1 disk, Sc 1, Sc 2 and Es 1 bipunctate numerous small p among sparse very larger p. Lateral N 1 without any wrinkles on posteroventral corner. Large deeply impressed p on the disk of Es 2. Subhorizontal surface of P mat because of very small p an mR, well distinct from posterior surface which bears sparse large impressed p. Lateral areas of P with very fine and shallow wrinkles. Very sparse and small p on tergal surfaces, becoming denser towards 5 th one. Bipunctate surface of 2 nd to 6 th Ste. Epipygium (6 th tergum) longitudinally wrinkled but apical stripe. Temples, genae, the whole of metasoma with mR on surfaces among p detectable at x30. Very fine transversal mR on metasoma but 1 st sternum and epipygium.

N o t e. It lacks right antenna, right tarsus and most of final Tarsomeri. Well distinct taxon, with slender aspect, looking very like to specimens of Hylomesa in colour pattern and habitus. From the relative proximity of the typical localities we could infer its coup-

ling with M. nyanzae , but we are dealing with areas owing high biodiversity and to extrapolate that synonymy without more definite proof it would be a hazardous action.
