Paramblynotus zairensis is similar to P. carinatus and P. kekenboschi in vertex with longitudinal carination as the dominant sculpture. P. zairensis and P. kekenboschi are further separated from P. carinatus by (1) median frontal carina extended only to upper third of lower face and (2) ocellar plate laterally defined by simple carinae. P. zairensis is distinquished from P. kekenboschi by (1) lateral propodeal carinae nearly parallel and (2) nucha dorsally glabrate.

Upper face, including antennal scrobes, glabrate and weakly foveate-reticulate; antennal scrobe indistinctly depressed and laterally defined by lateral carina. Median frontal carina present weakly from between antennal sockets to level of lower margin of eyes. Lower face irregularly foveate-reticulate with long pubescence. Anterior tentorial pits distinct. Clypeo-pleurostomal sulcus and epistomal sulcus almost form an arch. Clypeus punctate. Gena foveate-reticulate anteriorly and longitudinally costate posteriorly. Lateral occipital carina very developed, crestlike. Occiput glabrous. Anterior flange of pronotum glabrate with faint transverse striation. Anterior plate of pronotum glabrous mostly and punctate with pubescence posteriorly. Pronotum dorsomedially not distinctly raised; pronotal crest medially not raised into a process. Lateral pronotal carina distinct, meeting pronotal crest dorsomedially. Lateral surface of pronotum foveate-reticulate. Dorsal pronotal area glabrous, narrow, and complete to end of posterior margin of pronotum. Mesoscutum distinctly arched dorsally and nearly foveate-reticulate with indistinct transverse costae. Scutellar sulcus divided by a single median longitudinal carina; mesoscutellum foveate-reticulate and sloped posteriorly; posterior margin rounded in dorsal view. Mesopleural triangle ventrally well defined by smoothly curved carina and with white pubescence. Upper mesopleuron, including speculum, glabrous; median longitudinal impression percurrent with evenly distributed transverse carinae; lower mesopleuron glabrous and pubescent ventrally. Metepisternum foveate-reticulate and nude above, with

Propodeum areolate-reticulate; lateral propodeal carina percurrent and strongly curved medially; median propodeal area glabrate with a percurrent median longitudinal carina. Rs+M of forewing nebulous, arising from posterior middle of basal vein. Marginal cell 3.5 times as long as wide. Bulla on Sc+R 1 weakly present. Abdominal petiole 0.4 times as long as wide in lateral view and glabrate dorsally. Relative length of T3–7: 1.5:1.0:1.0:4.0:1.0; T3–5 glabrous; T6 glabrous except for a row of setigerous punctures; T7 punctate with a few setigerous punctures. T8 completely covered by T7. Front and middle legs sparsely punctate with pubescence; hindlegs sparsely punctate with pubescence except metacoxa glabrous dorsally and metatibia and metatarsomeres densely punctate with pubescence. Apical teeth of metatibia small, thin, and pointed apically. 1mt/2–5mt 5 0.50. MALE: Unknown. The new species is similar to P. rwandensis, but it differs from the latter in the following characters: antennal scrobes not distinctly depressed; mesoscutum foveate-reticulate; head, pronotum, mesoscutum, and mesoscutellum dark brown; antenna yellow; lateral occipital carinae well developed and crestlike; and median propodeal area glabrate. TYPE MATERIAL: HOLOTYPE: R, Cameroon: Nkoemvon, 1979-XI-19–30, D. Jockson coll. (NHM). DISTRIBUTION: Cameroon. ETYMOLOGY: The species is named after the type locality. Paramblynotus kekenboschi, new species FEMALE: Length 2.5 mm. Body dark brown to black except antenna and legs. Antenna yellow at base and becoming gradually black. Legs yellow.
