Description
HOLOTYPE WORKER. Measurements: HL 0.88, HW 0.72, HS 0.800, SL 0.66, PrW 0.57, WL 1.30, HFL 0.72, PeNL 0.26, PeH 0.58, PeNW 0.44, PeS 0.427. Indices: CI 82, SI 92, PeNI 77, LPeI 45, DPeI 169. Eyes present, of 5-6 small ommatidia. In full-face view apex of scape, when laid straight back from its insertion, just fails to touch the midpoint of the posterior margin; SL/HL 0.75. Cephalic dorsum coarsely and densely reticulate-punctate. Lateroventral surfaces of head completely covered with very coarse and conspicuous reticulate-punctate to punctate-rugulose sculpture, without discrete punctures separated by areas of smooth shining cuticle. Side of pronotum reticulate-punctate, strongly so but slightly less coarsely and densely than the head; this sculpture fades out dorsally and towards the midline the pronotum is almost entirely smooth. Mesonotum finely and densely punctate dorsally; the propodeal dorsum with disorganised punctate sculpture anteriorly, but this fades out posteriorly so that the mid-dorsal area just before the declivity is smooth. Metanotal groove absent on dorsum of mesosoma but a slight change of slope is present between mesonotum and propodeum. In profile the anterior margination of the mesopleuron is merely obtusely angled behind base of anterior coxa; without a projecting acute angle or tooth. Propodeum narrowly marginate between declivity and sides. Posterior face of petiole node with a series of short cuticular ridges that arise from the base of the peduncle. Petiole node with weak sculpture present on sides, and more weakly so on dorsum, fading out towards the midline. Maximum width of first gastral tergite in dorsal view is greater than the width of the second tergite at its midlength. Base of cinctus of second gastral tergite with cross-ribs conspicuous in dorsal view. Posttergite of second gastral segment, from posterior margin of cinctus to apex, very slightly broader than long. Disc of second gastral tergite with sharply incised punctures that are separated by areas of smooth cuticle; distance between punctures averages distinctly greater than diameters of the punctures.
Materials Examined
Holotype worker, Ethiopia (Abyssinia on main label): Gamo Prov., Bonghe valley, Gughe highlands, c. 9500- 10000 ft, 8.xii.1948, Ethiopia 1948-49, BM 1949-184, sifted humus under bamboo, near waterfall, south side of valley (H. Scott) (BMNH). Right funiculus is missing from holotype.
Diagnosis
This is a large, conspicuous and coarsely sculptured species, the only known Afrotropical species that combines the presence of radiating cuticular ridges at the base of the posterior face of the petiole node with relatively well-developed eyes. The condition of the metanotal groove is between absent and vestigially present. There is no strong, deep groove that cuts across and interrupts the surface, but a slight change of slope and vague hint of a depression remains.
