54 BULLETIN AMERICAN MUSEUM OF NATURAL HISTORY NO. 304 Scutellar sulcus divided by several submedian longitudinal carinae. Dorsal surface of mesoscutellum foveate-reticulate; posteriorly sloping gradually. Mesopleural triangle ventrally well defined by smoothly curved carina; upper mesopleuron foveate-reticulate; median impression percurrent with evenly spaced transverse carinae; speculum elevated and glabrous. Metanotal-propodeal complex coarsely foveate-rugose with dense pubescence. Propodeum not protruding posteriorly; postsubpleuron short. Lateral propodeal carina percurrent, distinctly curved medially, and forming a right angle with dorsal surface of nucha in lateral view; median propodeal carina percurrent and crossed by two transverse carinae. Rs+M of forewing nebulous, arising from basal vein at posterior two-thirds. Marginal and submarginal cells of forewing short; marginal cell 1.65 times as long as wide. Bulla on Sc+R 1 distinct. Abdominal petiole 0.3 times as long as wide in lateral view. Posterior margin of T7 of metasoma concave, exposing T8. Relative length of T3–8: 1.8:1:1.4:4.2:0.8:0.8; T4–8 densely finely punctate; T6–8 also with a band of larger setigerous punctures. All legs densely punctate with pubescence except femora sparsely so and metacoxa dorsally glabrous. Metatibia apically with four long, slender, apically pointed teeth. 1mt/2–5mt 5 0.45. MALE: Unknown. Paramblynotus prinslooi is unique among all species of Paramblynotus in (1) head strongly compressed longitudinally, occiput only slightly concave in dorsal view, and (2) propodeum not protruding posteriorly with lateral propodeal carinae forming a right angle with dorsal surface of nucha in lateral view; postsubpleuron short. This species is also unique among other species of the trisetosus group in (1) vertex, upper face, and genae glabrate-punctate with hairs; (2) mesoscutum foveate, without transverse costae; and (3) upper mesopleuron densely punctate with hairs in anterior half. TYPE MATERIAL: HOLOTYPE: R, South Africa, De Wildt, 1979-iv, G.L. Prinsloo coll. (PPRI). DISTRIBUTION: South Africa. ETYMOLOGY: The species is named after its collector Gerhard Prinsloo. Paramblynotus nigricornis Benoit, 1956 FEMALE: Length 3 mm. Head and mesosoma black; antenna, legs, and metasoma brown. Wings clear. Antenna 13-segmented with apical flagellomere less than twice the length of the subapical flagellomere. Ocellar plate distinctly raised. Vertex foveate-reticulate. Antennal scrobes longitudinally carinate above and glabrous below. Gena coarsely sculptured, rugose to rugulose. Clypeus diagonally carinate. Pronotal crest medially not raised into a triangular process. Upper mesopleuron foveate. Scutellar sulcus divided by a several longitudinal carinae. Metepisternum alveolate to rugose with dense pubescence in lower part, without elevated glabrous area. T6 of female metasoma the largest among all terga, lateral margin of T7 concave, T8 distinctly exposed. 1mt/2–5mt 5 0.65. MALE: Unknown. Paramblynotus nigricornis forms a distinct, monophyletic clade with P. samiatus, P. claripennis, P. maculipennis, and P. townesorum within the trisetosus group. They are easily separated from the rest of the species group by (1) ocellar plate distinctly raised; (2) T6 of female metasoma the largest, lateral margin of T7 concave, T8 distinctly exposed; (3) gena coarsely sculptured, rugose to rugulose; and (4) metepisternum without elevated nude area. Among the five species, P. nigricornis and P. claripennis are separated from the rest by having clear wings. In addition, P. nigricornis is unique among the five species in that it has 13-segmented antenna with apical flagellomere less than twice the length of the subapical one. MATERIAL EXAMINED: MRAC: 1R (holotype, one antenna and wings from one side are mounted on separate slide). DISTRIBUTION: Zaire: Kivu. Paramblynotus samiatus, new species FEMALE: Length 2.8 mm. Head and mesosoma dark; antenna, legs, and metasoma dark brown. Wings transparent; forewing with marginal and submarginal cells ferruginous. Vertex foveate-reticulate and longitudinally carinate. Eye prominent, laterally extended
2007 LIU ET AL.: REVISION OF PARAMBLYNOTUS (HYMENOPTERA) 55 much beyond outer margin of gena. Ocellar plate raised and defined laterally by an irregular carina lined along interior side by a row of irregular foveae. Upper face punctate-rugose laterally; antennal scrobe mostly longitudinally carinate and glabrous anteriorly, and laterally defined by a carina. Median frontal carina absent. Lower face entirely foveate-reticulate with pubescence and longitudinally carinate. Anterior tentorial pits distinct. Clypeo-pleurostomal sulcus and epistomal sulcus form a smoothly curved arch. Clypeus diagonally carinate. Gena glabrate-foveate and horizontally rugose in middle third. Occiput glabrous. Anterior plate of pronotum foveate-reticulate with pubescence. Pronotum dorsomedially not distinctly raised; pronotal crest medially raised into a small, triangular process. Lateral pronotal carina distinct, continuous dorsomedially, but not reaching pronotal crest. Lateral surface of pronotum foveate-reticulate. Dorsal pronotal area weakly carinate diagonally, narrowing posteriorly to reach to about two-thirds of dorsal posterior margin of pronotum. Mesoscutum foveate-reticulate, foveae set in rows between transverse costae. Scutellar sulcus divided by a median and two submedian longitudinal carinae. Dorsal surface of mesoscutellum foveate-reticulate; sloping gradually posteriorly. Mesopleural triangle ventrally well defined by smoothly curved carina; upper mesopleuron glabrous; median longitudinal impression percurrent with evenly spaced transverse carinae; speculum glabrous. Metanotal-propodeal complex areolate-punctate-rugose with metepisternum distinctly longitudinally rugose in upper part. Lateral propodeal carina percurrent, smoothly curved medially; median longitudinal propodeal carina percurrent and crossed by two transverse carinae. Rs+M of forewing nebulous, arising from basal vein at anterior third. Marginal cell 2.0 times as long as wide. Bulla on Sc+R 1 present. Abdominal petiole 0.5 times as long as wide in lateral view. Posterior margin of T7 of metasoma only slightly concave, exposing T8 as a small triangle. Relative length of T3–8: 1.5:1:1.3:3.0:0.6:0.4; T4 sparsely finely punctate; T5–8 densely finely punctate; T6–8 also with a band of larger setigerous punctures. All legs densely punctate with pubescence except femora sparsely so and metacoxa dorsally glabrous. Metatibia apically with four slender, apically pointed teeth. 1mt/2– 5mt 5 0.65. MALE: Unknown. Paramblynotus samiatus differs from all othe other species of the P. nigricornis clade in that its upper mesopleuron is entirely glabrous. TYPE MATERIAL: HOLOTYPE: R, South Africa, Zululand, Eshowe, 1925-IV-1–22, R.E. Turner coll. (NHM). DISTRIBUTION: South Africa: Zululand. ETYMOLOGY: From Latin, samio, to polish. The name is coined to describe the glabrous nature of its upper mesopleuron. Paramblynotus claripennis, new species FEMALE: Length 3.0 mm. Head and mesosoma black; antenna and metasoma light brown; legs dark brown. Wings entirely transparent with marginal cell slightly ferruginous. Antenna 12-segmented. Vertex entirely longitudinally carinate with foveae set between the carinae. Eye prominent, laterally extended much beyond outer margin of gena. Ocellar plate raised and defined laterally by a carina lined along interior side by a row of irregular foveae. Upper face asperous laterally; antennal scrobe longitudinally carinate posteriorly and glabrous anteriorly, and laterally defined by lateral carinae; lateral carinae delimiting ocellar plate extended beyond lower margin of antennal sockets. Median frontal carina present briefly. Lower face roughly foveate-reticulate with pubescence. Anterior tentorial pits distinct. Clypeo-pleurostomal sulcus and epistomal sulcus form a smoothly curved arch. Clypeus longitudinally rugose. Gena horizontally carinate-rugose with foveae. Occiput glabrous. Anterior plate of pronotum coarsely punctate with pubescence. Pronotum dorsomedially not distinctly raised; pronotal crest medially raised into a small, triangular process. Lateral pronotal carina distinct, not reaching pronotal crest. Lateral surface of pronotum foveate-reticulate with secondary
