Nothing is known about the biology of Syllophopsis elgonensis.


Bolton (1987) - M. elgonense is separated from Syllophopsis jonesi and Syllophopsis thrascolepta by its shorter scapes, from the Rwandan Syllophopsis sersalata and the west African Syllophopsis malamixta by its smooth mesopleuron, from Syllophopsis modesta by its deeply impressed metanotal groove, and from Syllophopsis cryptobia by being larger and having the propodeum produced into an acute peak behind the metanotal groove. At present elgonense is known only from Kenya.

Bolton (1987) - TL 1.9-2.0, HL 0.48-0.51, HW 0.40-0.43, CI 80-84, SL 0.36-0.39, SI 90-95, PW 0.29-0.30, AL 0.56-0.60 ( 8 measured).

Eyes of a single ommatidium, maximum diameter 0.05-0.07 x HW. Antennal scapes relatively short, SI < 100. Promesonotal dorsal outline evenly rounded in profile, the metanotal groove conspicuously impressed. In profile the propodeal dorsum immediately behind the groove with a small peak, which appears as a weak transverse crest in dorsal view. Propodeal dorsum behind this peak sloping posteriorly to the pair of short broad denticles or prominent triangular angles which mark the junction of dorsum and declivity. All dorsal surfaces of head and body with numerous short hairs and very sparse pubescence. Propodeum with only 1-2 pairs of hairs. Pubescence on sides of head behind eyes decumbent to appressed, that on the antennal scapes more elevated but not erect. Unsculptured everywhere except for scattered minute hair-pits, and some faint striation on the bullae of the metapleural glands; lower halves of mesopleuron smooth and shining. Colour uniform yellow.

Type Material

Bolton (1987) - Holotype worker, Kenya: Mt Elgon, camp 1, st. 13, 2100 m, 1932-33 (Jeannel & Chappuis) (Musee National d'Histoire Naturelle) [examined].

The holotype is much abraded and densely coated with old glue which obscures the pilosity and some of the surface detail.
