Etymology

Named after the Dzanga-Sangha special forest reserve, which forms part of the Dzanga-Ndoki National Park. Noun in apposition.

Diagnosis

Belongs to Paramblynotus trisetosus clade of Liu et al. (2007)^[1]. Female with 13 segmented antennae (Fig. 18A), male with 14-segmented antennae (Fig. 19D), gradually darkening from base to tip; ocellar plate raised, bound by carinae anterolaterally; vertex with longitudinal carination; median frontal carina on face very weak and only defined between toruli (Fig. 18E) (extending to lower face or clypeus in the similar Paramblynotus kekenboschi and Paramblynotus zairensis); shares strongly curved lateral propodeal carinae (Fig. 18F) with Paramblynotus kekenboschi, but the nucha is glabrous as in Paramblynotus zairensis (dorsally longitudinally carinate in Paramblynotus kekenboschi); Paramblynotus zairensis has parallel lateral propodeal carinae. Upper mesopleuron and speculum glabrous; metepisternum with a median smooth glabrous area (Fig. 18C). T6 largest, T8 covered entirely by T7 (Fig. 19A). Wings ferruginous in marginal cells (Fig. 19B).

Description

FEMALE (Figs 18A–F, 19A–C). Length 2.8 mm. Head and mesosoma black; antenna proximally yellow grading to black distally, legs yellow, and metasoma dark brown (Fig. 18A). Forewing with marginal and submarginal cells ferruginous (Fig. 19B). Antennal F1 1.38× longer than F2 (Fig. 18C). Vertex foveate-reticulate and longitudinally carinate, with medial transverse smooth patch adjacent to occiput (Fig. 18D). Eye normal, extending laterally slightly beyond outer margin of genae in anterior view (Fig. 18E). Ocellar plate raised, defined antero-laterally by a carina. Ocelli large, diameter of median ocellus equal to distance between median and lateral ocellus. Face areolet-rugose with scattered white pubescence; antennal scrobe with fine cross striations, glabrous posteriorly with pubescence anteriorly, outside lateral edge defined by a carina. Median frontal carina weakly present between toruli, not extending onto face (Fig. 18E). Anterior tentorial pits distinct situated in slight depressions. Clypeus anteriorly excavated, margin strongly convex, weakly bilobed (Fig. 18E). Genae foveate-reticulate. Genal carina strong, extending to dorso-posterior eye margin. Occiput glabrous, smooth, shiny. Anterior plate of pronotum glabrous, smooth, shiny with two submedian pronotal depressions. Pronotum dorsomedially not distinctly raised; pronotal crest medially raised into a small sharp ridge (Fig. 18C). Lateral pronotal carina distinct, continuous dorsomedially, but not reaching pronotal crest. Lateral surface of pronotum strongly glabrous-foveate (Fig. 18C). Mesoscutum glabrous-foveate (Figs 18C–D). The two scutellar foveae not divided (Fig. 18D). Dorsal surface of mesoscutellum glabrous-foveate; sloping gradually posteriorly (Fig. 18D). Mesopleural triangle ventrally defined by smoothly curved carina; upper mesopleuron glabrous, smooth, shiny; median longitudinal impression present with evenly spaced transverse carinae; speculum glabrous, smooth, shiny (Fig. 18C). Metanotal-propodeal complex areolate-punctate-rugose with metepisternum areolate-punctate in upper part, smooth medially and pubescent ventrally (Fig. 18C). Lateral propodeal carina present, strongly curved medially; median longitudinal propodeal carina present and crossed by two transverse carinae (Fig. 18F). Posterior medial propodel area and nucha glabrous, smooth. Rs+M of forewing absent except for nebulous distal third (Fig. 19B). Marginal cell 1.8 times as long as wide. Bulla on Sc+R1 present. Abdominal petiole 3.5× as wide as long in dorsal view, 2.5× higher than long in lateral view, longitudinally carinate (Figs 18F, 19A). T6 posterior ventral margin sinuate; posterior ventral margin of T7 evenly curved covering T8 (Fig. 19A). Relative length of T3–8: 20:13:15:40:16:0; T7 sparsely finely punctate; T3–6 smooth, shiny; T6 & T7 medially with a row of long white setae (Fig. 19F). All legs smooth, shiny pubescent, yellow contrasting strongly with body (Figs 18A, 19A). Metatibia apically with four small teeth. First metatarsal segment 0.60× remaining four segments.
MALE (Figs 19D–F, 20A–E). Length 2.7 mm. Very similar to female, except for longer abdominal petiole, 2.2× as wide as long in dorsal view, 1.8× higher than long in lateral view (Figs 19F, 20C). Tergite 5 laterally expanded and by far the largest (Fig. 20C).

Distribution

South Africa.
