Name

Paramblynotus ruvubuensis van Noort & Buffington sp. n. – Wikispecies link – ZooBank link – Pensoft Profile

Type material

HOLOTYPE. Female: Burundi, Ruvubu National Park, 1382m, 2.98144°S, 30.45531°E, Malaise trap, edge of forest, near Ruvubu river, 26 Nov–10 Dec 2009, R. Copeland SAM-HYM-P044100 (SAMC).

Distribution

Burundi.

Etymology

Named after the type locality along the Ruvubu River in the Ruvubu National Park.

Diagnosis

Belongs to the Paramblynotus trisetosus clade within the Paramblynotus trisetosus species-group of Liu et al. (2007)^[1]. Immediately distinquishable from other species within this clade by the presence of an infuscate patch, centered on the marginal and submarginal cells of the fore wing (Fig. 27E). It shares the basket-like tuft of setae on the terminal end of T9 (ovipositor sheaths) with a number of other species within this clade (Fig. 26F).

Description

FEMALE. Length 3 mm. Head and mesosoma black, metasoma, coxae, femora dark brown; tibiae and tarsi light brown. Wings clear; weakly infuscate in marginal and submarginal cells extending towards apex slightly past vein RS (Fig. 27E). Antenna 13-segmented; flagellum thicker apically, distal segment longest and widest with three interspersed rows of multiporous plate sensilla (MPS); median flagellomeres constricted proximally and apically; light brown except for last two segments which are blackish-brown (Figs 26A–E). Vertex foveate (Fig. 27C). Eye prominent, distinctly extended laterally beyond outer margin of genae (Fig. 27A). Ocellar plate raised and weakly defined by lateral reticulate carinae; posteriorly foveate, anteriorly areolate (Figs 27A–C). Median frontal carina extending from level of toruli to approximately the level of the ventral eye margins (Fig. 27B). Antennal scrobe glabrous, medially smooth, with fine longitudinal carinae dorsally. Whole face coarsely areolet-rugose with pubescence (Fig. 27A). Anterior tentorial pits distinct, situated in shallow depressions. Clypeus diagonally carinate laterally, with an anterior finely carinate medial excavation (Fig. 27A). Genae coarsely areolet-rugose. Genal carina extending to behind dorso-posterior eye margin. Occiput glabrous, smooth, shiny. Anterior plate of pronotum ventro-medially glabrous, polished, laterally and dorsally setose and sparsely punctate. Pronotum dorsomedially not distinctly raised into a process (Fig. 26C). Lateral pronotal carina distinct, almost meeting pronotal crest dorsomedially. Lateral surface of pronotum areolet-rugulose (Fig. 26C). Mesoscutum distinctly arched dorsally and foveate-reticulate with indistinct transverse costae (Figs 26C–E). Notauli evident posteriorly as smooth depressions with cross carinae (Figs 26D–E). The two scutellar foveae not subdivided by carinae; mesoscutellum areolet-rugose and sloped posteriorly; posterior margin rounded in dorsal view (Fig. 27D). Mesopleural triangle ventrally well defined by smoothly curved carina and with white pubescence. Mesopleuron, including speculum, glabrous, polished; median longitudinal impression present with transverse carinae; lower mesopleural margin bordered with pubescence (Fig. 26C). Metepisternum areolet-rugose and glabrous dorsally, conspicuously pubescent ventrally (Fig. 26C). Propodeum areolate-rugose; lateral propodeal carina curved medially; median propodeal area glabrate to rugulose; median longitudinal carina present, with transverse carina present anteriorly (Fig. 27D). Rs+M of forewing nebulous, arising two-fifths up basal vein (Fig. 27E). Marginal cell 2.2 times as long as wide. Bulla on Sc+R1 absent. Abdominal petiole 0.7× as long as high in lateral view, 1.7× longer than wide in dorsal view, longitudinally carinate (Figs 26C–F). Relative length of T3–7: 14:9:9:18:10; T3–5 glabrous, smooth; T6 finely punctate with a medial row of long white setae; T7 punctate with a medial row of long white setae; T8 mostly covered by T7, but ventro-posteriorly visible (Fig. 26F). All coxae smooth shiny with lines of pubescence dorsally and medially; femora finely punctate, strongly setose; pro- and meso- tibiae and tarsi finely punctuate with pubescence; meta-tibiae and meta-tarsomeres densely punctate with pubescence (Figs 26A, 26C, 26F). Four dorso-apical teeth on metatibia. Proximal metatarsal segment about half the length of distal 4 segments combined.

Note

There is a damaged specimen in the Royal Museum for Central Africa (RMCA) collection (Congo Belge: P.N.A., Escarpem. De Kabasha, 1500m, 14.xii.1934, G.F. de Witt: 919; Paramblynotus trisetosus group, det Ronquist, 1994) that possibly may be conspecific with Paramblynotus ruvubuensis, but given the damage we are unable to assign this to a species with any confidence. The metasoma and antennae are missing, as well as the wings and all legs on the right side of the body. Based on interpretation of characters available for observation the specimen appears to be related to Paramblynotus ruvubuensis. The specimen keys to Paramblynotus ruvubuensis, with which it shares the infuscate patch of the forewing.
