FEMALE. Length 4.5 mm. Head, antennae (except for terminal segments which are darker), mesosoma (except for propodeum and mesopleuron which are black) reddish-brown; legs and metasoma dark brown. Wings clear (Fig. 10A). Entire head punctate-rugose, strongly pubescent. Eyes small, not extending beyond outer margin of genae in anterior view (Fig. 10E); 1.4× length of malar space. Antenna 13 segmented; F1 same length as F2; flagellum widening toward apex. Vertex alveolate, ocellar plate raised; ocelli small, median ocellus diameter 0.62× distance between lateral and median ocellus (Fig. 11A). Face punctate-rugose, humped between toruli and clypeal margin (Fig. 10E), protruding medially in lateral view (Fig. 10C); antennal scrobe rugose. Vertex rugose with two weak lateral carinae extending from each torulus towards lateral ocelli; strongly keeled medial carina present between toruli extending from median ocellus and fading below toruli (Fig. 10E). Occiput concave in dorsal view, alveolate without carinae. Lower face with two weak excavations at upper clypeal margin, containing anterior tentorial pits. Clypeus rugose, margin strongly convex. Genae large, swollen (Fig. 10C). Mesosoma dorsally with scattered long pubescent (Fig. 10D). Anterior flange of pronotum weakly punctuate/foveate; plate of pronotum medially glabrate and punctate/foveate with pubescence laterally (Fig. 11C). Pronotum dorsomedially distinctly raised, in lateral view distinctly higher than anterior margin of mesoscutum (Fig. 10C). Pronotal crest prominent, raised into a sharp carina running parallel to mesoscutal margin, fronting a horizontal shelf on posterior prontal margin that comprises longitudinally carinate foveae (Fig. 11A). Lateral pronotal carinae distinct, not reaching pronotal crest dorsomedially. Lateral surface of pronotum foveate with smooth areas (Fig. 11D). Mesoscutum foveate-reticulate with foveae set in irregular rows between transverse costae irregularly raised into strong backward pointing teeth (Figs 10C–D). The two scutellar foveae not subdivided by submedian longitudinal carinae (Fig. 11B). Mesoscutellum foveate-reticulate; posteriorly raised and projected into a truncate lamella with a slight emargination in dorsal view (Fig. 11B). Mesopleural triangle ventrally defined by a smoothly curved carina; upper mesopleuron foveate-reticulate; median impression vertically carinate; speculum finely longitudinally carinate (Fig. 11D). Metapectal-propodeal complex coarsely foveate-rugose laterally with dense pubescence. Dorsellum with two medial foveae; laterally excavated with fine pubescence in lateral depressions. Median propodeal area areolate-reticulate (Fig. 11B). Rs+M of forewing defined, arising from the base of basal vein (Fig. 12C). Marginal cell 2.7 times as long as wide. Abdominal petiole short, longitudinally carinate, 0.22 times as long as wide in dorsal view (Fig. 11E). Posterior ventral margin of metasomal T6 and T7 sinuate (Fig. 10A). T7 largely concealed benath T6 only partially visible laterally and covered on dorso-posterior central margin. T8 marginally exposed with two pothole excavations on each side, a smaller circular one surrounding the spiracle and a second larger oval one adjacent to the first and extending to posterior margin (Figs 12 A–B). Relative dorsal length of T3–8: 21:13:15:12:0:4. Tergites 4-8 finely punctate; T3 polished. All legs sparsely punctuate, strongly pubescent, except metacoxae dorsally glabrous, smooth. Mesotibial outer spur shorter than inner spur; metatibial spurs subequal in length. Ratio of first metatarsomere to the remaining 4 metatarsomeres combined: 0.65. MALE. Unknown. Remarks. This is the most species-rich group within the Afrotropical region with 23 previously described species and a further five species added here. The species-group is only known from the African mainland. Diagnosis. Species in this group are typically smaller than those in other species-groups, and are the easiest to confuse with Figitidae. They are characterized by having a flat pronotal crest (or, pronotal crest absent); the mesoscutum is foveate-reticulate or with continuous transverse carinae with foveae set in rows looking like saw teeth in lateral view; in most species, the speculum is perfectly smooth (gently striate in Paramblynotus vannoorti); and the median propodeal area is distinctly delimited by lateral propodeal carinae, and posteriorly is not foveate-reticulate. Careful attention to the metasomal sclerites will prevent confusing trisetosus-group Paramblynotus with Figitidae. http://www.waspweb.org/Cynipoidea/Liopteridae/Keys/index.htm 1 Head compressed longitudinally; occiput not concave in dorsal view.
