Apical teeth of metatibia pointed apically; 1mt/2–5mt 5 1.5....... P. yangambicolus Paramblynotus mixtus, new species FEMALE: Length 4 mm. Body entirely dark; antennae and legs dark brown. Wings clear. 1tm/2–5tm 5 1.1. Head, in profile, medially not distinctly raised anteriorly. Vertex foveate-reticulate. Median frontal carina low, dorsally slightly flattened, bifurcated posteriorly to delimit a glabrous triangular area below anterior ocellus, and ventrally extended in lower face to the level of lower margin of eye. Eye extended laterally beyond outer margin of gena. Upper face foveate laterally; antennal scrobe foveate rugose. Lower face and clypeus entirely foveate-reticulate with pubescence.

Anterior plate of pronotum before lateral pronotal carinae densely punctate with pubescence. Pronotum dorsomedially distinctly raised, in lateral view height as highest point of mesoscutum.

Dorsal pronotal area foveate, reaching only to middle of dorsal posterior margin of pronotum. Mesoscutum foveate-reticulate with foveae set in rows between transverse costae. Scutellar foveae subdivided by submedian longitudinal carinae weaker than median carina. Mesoscutellum foveate-reticulate; sloping posteriorly in lateral view; posterior margin rounded in dorsal view. Mesopleural triangle ventrally defined by a smoothly curved carina; upper mesopleuron irregularly foveolate-reticulate; median impression percurrent with several vertical carinae; speculum with distinct longitudinal carinae. Metanotal-propodeal complex coarsely foveate-rugose with dense pubescence except nude in upper metepisternum. Lateral propodeal carina indistinguishable except anteriorly; median propodeal area areolate/foveate-reticulate. Rs+M of forewing arising from basal vein at posterior third. Abdominal petiole 0.4 times as long as wide in lateral view. Relative length of T3–8: 1.7:1:1:0.9:0.15:0.4. T4–8 densely finely punctate; T8 also with a few slightly larger setigerous punctures set in one row. All legs densely punctate with pubescence except metacoxa dorsally glabrous. Metatibia apically with four slender, pointed teeth. 1mt/2– 5mt 5 1.0. MALE: Unknown. Paramblynotus mixtus is distinctly different from the other two species of yangambicolus group in a number of characters. Antennae are not laterally compressed distally though enlarged toward apex; median frontal carina ventrally extended almost to clypeus in lower face. Antennal scrobe coarsely rugose. Eye prominent, protruding beyond gena. Mesoscutum anteriorly curved in lateral view; mesoscutellum sloped strongly posteriorly; mesopleural triangle ventrally well defined by a smoothly curved carina; upper mesopleuron irregularly foveolate-reticulate; speculum with distinct and rather strong longitudinal carinae. Wings clear; marginal cell of forewing only slightly longer than submarginal cell. Metasoma oval in profile, almost as long as head and mesosoma combined; terga 3–6 subequal in size dorsally; metasomal sterna 4–6 entirely covered by sternum 3. TYPE MATERIAL: HOLOTYPE: R, Kenya, Ukunda, 1968-I-24, K.V. Krombein coll. (USNM). DISTRIBUTION: Kenya: Ukunda. ETYMOLOGY: From Latin, mixtus, mingled. The name describes the species’ possession of a number of obviously plesiomorphic characters that are more frequently found in the other species groups.

Wings ferruginous with marginal cell somewhat darker. 1mt/2–5mt 51.4. Head, in profile, medially distinctly raised anteriorly. Vertex foveate-reticulate. Median frontal carina simple and present only between upper margin of antennal sockets to anterior ocellus. Eye laterally not extended beyond outer margin of gena. Upper face glabrous-punctate laterally; antennal scrobe longitudinally carinate. Lower face entirely foveate-reticulate with pubescence. Anterior tentorial pits indistinct. Clypeo-pleurostomal sulcus and epistomal sulcus straight, not forming smoothly curved arch. Clypeus rugose. Gena foveate-reticulate and vertically rugose. Occiput glabrous. Anterior flange of pronotum longitudinally carinate; anterior plate of pronotum glabrate anteriorly and punctate/foveate with pubescence posteriorly. Pronotum dorsomedially distinctly raised, in lateral view distinctly higher than highest point of mesoscutum. Pronotal crest prominent and medially without emargination. Lateral pronotal carina distinct, not reaching pronotal crest dorsomedially. Lateral surface of pronotum foveate-reticulate, with slightly glabrate posterior area. Dorsal pronotal area distinctly present only to posterior two-thirds of dorsal posterior margin of pronotum and distinctly transversely carinate anteriorly (carination faint posteriorly). Mesoscutum foveate-reticulate with foveae set in rows between transverse costae. Scutellar foveae not subdivided by submedian longitudinal carinae. Mesoscutellum foveate-reticulate; posteriorly raised and projected into a truncate lamella with a slight emargination in dorsal view.

Metanotalpropodeal complex coarsely foveate-rugose with dense pubescence. Lateral propodeal carina distinct anteriorly and inseparable from the longitudinal carinae posteriorly; median propodeal area areolate-reticulate, with a distinct transverse carina across middle. Rs+M of forewing arising from basal vein at middle. Abdominal petiole 0.3 times as long as wide in lateral view. Relative length of T3–8: 1.5:1:1:1.8:0.5:0.25. T4–8 densely finely punctate; T8 also with a few slightly larger setigerous punctures set in one row. All legs densely punctate with pubescence except metacoxa dorsally glabrous. Metatibia apically with four stout, pointed teeth. 1mt/ 2–5mt 5 1.5. MATERIALS EXAMINED: 6RR: MRAC, 1R(T); NHM, 5RR. DISTRIBUTION: Zaire:Yangambi;Uganda: Mpanga, Itwala Forest, and Kawanda. BIOLOGY: Benoit (1956) stated in his original description of the species that the holotype was captured on a dead tree trunk of Drypetes gossweileri, which belongs to Euphorbiaceae. The two specimens from Mpanga, Uganda, bear labels reading ‘‘Lepidoptera’’; the two specimens from Itwala Forest, Uganda, bear labels reading ‘‘ex. Coleoptera’’.

Median frontal carina simple and present only between antennal sockets and anterior ocellus. Eye laterally not extended beyond outer margin of gena. Upper face including antennal scrobe longitudinally carinate. Lower face entirely foveate-rugose with pubescence. Anterior tentorial pits indistinct. Clypeo-pleurostomal sulcus and epistomal sulcus straight, not forming smoothly curved arch. Clypeus foveate-rugose. Gena finely vertically carinate-foveate and otherwise glabrate foveate-reticulate. Occiput glabrous with setigerous punctures. Anterior flange of pronotum longitudinally carinate; anterior plate of pronotum glabrate anteriorly and punctate/foveate with pubescence posteriorly.
