66 BULLETIN AMERICAN MUSEUM OF NATURAL HISTORY NO. 304 Relative length of T3–7: 1.7:1.0:1.0:2.5:1.1; T3–5 glabrous; T6 finely punctate with a few setigerous punctures in a row; T7 punctate with a row of setigerous punctures. T8 entirely covered by T7. Front and middle legs sparsely punctate with pubescence; hindlegs sparsely punctate with pubescence except metacoxa dorsally glabrous and metatibia and metatarsomeres densely punctate with pubescence. Apical teeth of metatibia long, thin, and pointed apically. 1mt/2–5mt 5 0.60. MALE: Unknown. Paramblynotus carinatus is similar to P. kekenboschi and P. zairensis, but it can be easily separated from them by (1) median frontal carina distinct in lower face, extending beyond lower margin of eyes reaching epistomal sulcus; and (2) ocellar plate with a row of relatively uniform large foveae along lateral carina. TYPE MATERIAL: HOLOTYPE: R, Zaire, P.N.A., Nyasheke, Volley Nyamuragia (1,820 m), 1935-VI-14–26, G.F. de Witte coll. (NHM). DISTRIBUTION: Zaire. ETYMOLOGY: From Latin, carina, keel. The species name describes the carinate sculpture on the vertex. Paramblynotus immaculatus, new species FEMALE: Length 1.9 mm. Head and mesosoma black and other body parts dark brown. Wings slightly, evenly ferruginous. Antenna 13-segmented; flagellum gradually expanded apically; median flagellomeres not constricted. Vertex foveate-reticulate. Eye prominent, distinctly extended laterally beyond outer margin of gena. Distance between posterior ocelli 3.3 times as wide as the distance between posterior ocellus and eye. Ocellar plate slightly raised and not distinctly defined laterally by a carina; the reduced lateral carina of ocellar plate meeting medially above antennal sockets and lined by a row of foveae along interior side; ocellar plate foveate; median frontal carina distinct in lower face, reaching to epistomal sulcus anteriorly and bifurcated posteriorly to delimit a glabrous triangular area beneath anterior ocellus. Upper face glabrate laterally and antennal scrobes glabrous except foveate medially (at the level of anterior ocellus); antennal scrobe defined by carina laterally. Lower face coarsely foveate-reticulate with pubescence. Anterior tentorial pits distinct. Clypeo-pleurostomal sulcus and epistomal sulcus almost form an arch. Clypeus longitudinally carinate. Gena coarsely foveaterugose. Lateral occipital carina extended dorsally to meet lateral carina of antennal scrobe. Occiput glabrous. Anterior flange of pronotum finely longitudinally carinate. Submedian pronotal depression fused medially. Anterior plate of pronotum glabrous and punctate. 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 dorsolaterally and longitudinally rugose lateroventrally. Dorsal pronotal area glabrate-punctate and reaching to end of posterior margin of pronotum. Mesoscutum distinctly arched dorsally and foveate-reticulate. Scutellar sulcus divided by single median longitudinal carina; mesoscutellum foveate-reticulate; posterior margin broadly emarginate in dorsal view. Mesopleural triangle ventrally well defined by smoothly curved carina and with white pubescence. Upper mesopleuron glabrous, distinctly depressed; speculum longitudinally carinate; median longitudinal impression percurrent with three unevenly distributed transverse carinae. Lower mesopleuron glabrous; pubescence sparse above and dense ventrally. Metepisternum depressed and nude above, with an oblique, elevated glabrous area across the middle, and conspicuously pubescent ventrally. Propodeum, including median propodeal area, areolate-reticulate; lateral propodeal carina present only anteriorly and median longitudinal carina percurrent. Nucha glabrous. Rs+M of forewing nebulous, arising from posterior end of basal vein. Marginal cell 2.6 times as long as wide. Bulla on Sc+R 1 absent. Abdominal petiole 0.36 times as long as wide in lateral view. Relative length of T3–8: 1.3:1.0:2.0:1.2:0:0.4; T3–5 glabrous; T6 finely punctate; T7 almost completely covered by T6 except posterolaterally slightly exposed; T8 punctate with a few foveae.

2007 LIU ET AL.: REVISION OF PARAMBLYNOTUS (HYMENOPTERA) 67 cence except metacoxa dorsally glabrous and metatibia and metatarsomeres densely punctate with pubescence. Apical teeth of metatibia long, thin, and pointed apically. 1mt/ 2–5mt 5 0.64. MALE: Unknown. Paramblynotus immaculatus, antistatus, scalptus, vannoorti, diminutus, angolensis, and minutus form a very distinct, monophyletic clade within the trisetosus group. This clade is characteristic in having (1) very conspicuous anterior tentorial pits; (2) distance between posterior ocelli at least three times as wide as distance between posterior ocellus and eye; (3) speculum longitudinally carinate; (4) T5 of female dorsally expanded and the largest metasomal tergum, T7 largely or entirely covered by T6, T8 exposed; and (5) wings with different color patterns; Rs+M vein of forewing arising from posterior end of basalis. Paramblynotus immaculatus can be easily separated from the other species of this clade by having (1) wings evenly ferruginous and without darker bands, (2) mesoscutellum posteriorly with a broad emargination, and (3) median frontal carina almost reaching clypeus. TYPE MATERIAL: HOLOTYPE: R, Zaire, Pidigala, 1952-iv-23, H. De Saeger coll. (NHM). DISTRIBUTION: Zaire. ETYMOLOGY: From Latin, im- not, and macula, mark, spot. The name describes the evenly ferruginous wings of the species. Paramblynotus antistatus, new species FEMALE: Length 2.1 mm. Body black to dark brown with antennae and legs yellow to yellow brown. Forewing brown in about basal two-thirds and clear beyond the tip of marginal cell. Antenna 13-segmented; flagellum gradually expanded apically; median flagellomeres not constricted. Vertex largely glabrous with sparse punctures, slightly rugose laterally. Eye prominent, distinctly extended laterally beyond outer margin of gena. Distance between posterior ocelli 3.0 times as wide as the distance between posterior ocellus and eye. Ocellar plate not raised and not defined laterally by a carina; median frontal carina extended from anterior ocellus to slightly beyond lower margin of antennal sockets. Upper face, including antennal scrobe, coriarious; antennal scrobes only slightly depressed, defined by carina laterally. Lower face coriarious above and transversely rugose with foveae ventrally. Anterior tentorial pits distinct. Clypeo-pleurostomal sulcus and epistomal sulcus almost form an arch. Clypeus glabrate and weakly longitudinally carinate. Gena coriarious. Lateral occipital carina indistinct beyond vertex. Occiput glabrous. Anterior flange of pronotum glabrous. Submedian pronotal depressions distinctly separated medially. Anterior plate of pronotum glabrate and coarsely punctate. Pronotum dorsomedially not distinctly raised; pronotal crest medially not raised into a process. Lateral pronotal carina distinct, not reaching pronotal crest dorsomedially. Lateral surface of pronotum foveate-reticulate. Dorsal pronotal area glabrate-punctate and reaching to end of posterior margin of pronotum. Mesoscutum distinctly arched dorsally and foveate-reticulate. Scutellar sulcus divided by a single median longitudinal carina; mesoscutellum foveate-reticulate; posterior margin round in dorsal view. Mesopleural triangle ventrally well defined by smoothly curved carina and partly with white pubescence. Upper mesopleuron glabrous, distinctly depressed; speculum longitudinally carinate; median impression percurrent with three unevenly distributed transverse carinae. Lower mesopleuron glabrous; pubescence sparse above and dense ventrally. Metepisternum foveate-rugose, nude above and conspicuously pubescent ventrally. Propodeum, including median propodeal area, areolate-reticulate; lateral and median propodeal carinae present only anteriorly; lateral propodeal carina with distinct pubescence dorsally. Nucha glabrous. Rs+M of forewing nebulous, arising from close to posterior end of basal vein. Marginal cell 2.0 times as long as wide, and as long as submarginal cell. Bulla on Sc+R 1 absent. Abdominal petiole 0.3 times as long as wide in lateral view. Relative length of T3–8: 1.3:1.0:2.0:1.1:0.4:0.4; T3–4 glabrous; T6–7 punctate; T7 of metasoma distinctly exposed; T8 punctate with a few foveae. Front and
