return to key {link to the Hymenoptera Name Server} Type location Nigeria (Snelling, 1979a: 3, illustrated); holotype and one paratype worker from CRIN, collector B. Taylor, 1976 .

Snelling's description is at {original description}.

{Cataulacus boltoni}Original description of Nigeria specimens (Cataulacus species T, Taylor, 1979: 17). WORKER. TL 2.74-3.08 mm, HL 0.75-0.87, HW 0.75-0.78, SL 0.36-0.37, PW 0.53-0.59
Very distinctive sculpturation and large eyes. Occipital corners of head with a single denticle, and sides of head behind the eyes denticulate. Dorsum of head finely reticulate-rugose, with the rugae more obvious anteriorly. Alitrunk dorsum strongly rugose, longitudinal on top of the pronotum, rugae running obliquely on the lateral alitrunk and continuing onto the dorsum where they become progressively more transverse on mesonotum and propodeum. Dorsal and lateral surfaces of petiole and postpetiole are longitudinally rugose. Femora also strongly longitudinally rugose. Hairs on all dorsal surfaces numerous, progressively shorter and stouter anteriorly, those on anterior of cephalic dorsum, especially the clypeus, strongly clavate. Pronotum is weakly marginate, with the humeral angles with a triangular tooth; margination with minute denticles, terminating posteriorly in a single larger denticle close to the promesonotal junction. Mesonotum and propodeum not marginate but with a few minute denticles. Propodeal spines short and acute.
I collected the two workers from low vegetation at widely separated sites on the Cocoa Research Institute of Nigeria, Idi Ayunre, by the W20 and SC6 cocoa blocks, latter with aphids and Camponotus species T). Personally, it was somewhat annoying to read Snelling's dedication - "to Mr. Barry Bolton, who recognized the novelty of this species and sent it to me for inclusion in this paper". As will be obvious, it was I who both collected it and recognized the "novelty" - hence my separation on my original label, specimens deposited with Bolton in 1976, and in my Field Guide; but I knew nothing of Bolton passing the specimen to Snelling.
