Type material

HOLOTYPE. Female: Uganda, Kibale National Park, Kanyawara, Makerere University Biological Field Station, 1587m, 0°33.408'N, 30°22.603'E, 30vii-5viii.2005, S. van Noort, UG05-M10, Malaise trap, degradedmid-altitude Rainforest, SAM-HYM-P025019 (SAMC). PARATYPES. 2F: one specimen same data as holotype (USNM); second specimen: Kenya, Western Prov., Kakamega Forest, Rondo, 0°14.13'N, 34°51.87'E, MT, 17–31.VII.2006, R. Copeland (NMKE).

Distribution

Uganda, Kenya.

Etymology

The rainforest at Kanyawara, the area around MUBFS (Makerere University Biological Field Station) where the holotype was collected, is classified by foresters as Parinari forest, distinguished on photo aspect maps by the large spreading crowns of Parinari excelsa Sabine, a valuable timber tree. Noun in apposition.

Diagnosis

Belongs to the Paramblynotus trisetosus clade within the Paramblynotus trisetosus species-group of Liu et al. (2007)^[1]. The female flagellum is distinctly thicker toward the apex with the distal flagellomeres 1–3 black, contrasting with the preceding yellow-orange flagellomeres (Fig. 25A), a character state shared with Paramblynotus coxatus, Paramblynotus fuscapicalus and Paramblynotus alexandriensis. However, Paramblynotus parinari has finely punctate antennal scrobes without longitudinal carinae posteriorly, whereas these other three species have heavily and densely punctate antennal scrobes with longitudinal carinae posteriorly. A distinct, basket-like, dense tuft of setae is present on the terminal portion of T9 (ovipositor sheaths), a character state shared with a number of other species within the Paramblynotus trisetosus clade (Fig. 25F).

Description

FEMALE. Length 2–2.5 mm. Head, mesosoma black; metasoma, coxae and femora (in part) dark brown; antennae and rest of legs light yellow; terminal segment of antennae dark brown (Fig. 25A). Wings transparent (Fig. 25A). Entire head with the exception of the occiput strongly pubescent (Fig. 25E). Eyes prominent, bulbous, laterally extended slightly beyond outer margin of genae in anterior view (Fig. 25E). Antenna 13 segmented; F1 shorter than F2; flagellum slightly widened toward apex (Figs 25A–B). Vertex foveate, carinae absent; ocellar plate distinctly raised, deeply foveate; ocelli large, their diameter as great as distance between lateral and median ocellus (Fig. 25D). Face punctate-rugose, keeled medially between toruli and clypeal margin; protruding in lateral view; antennal scrobe mostly smooth with minute punctuation (Fig. 25E). Occiput concave in dorsal view, smooth without a carina. Lower face deeply foveate, anterior tentorial pits set into shallow, foveate cavities (Fig. 25E). Clypeus entirely foveate. Genae with distinct foveae along eye margin. Mesosoma strongly pubescent (Figs 25C–D). Single submedian pronotal depression absent; lateral foveae present, open. Anterior plate of pronotum puberulous. Pronotum dorsomedially with swollen rim, crest absent (Fig. 25C). Lateral carinae of pronotum strong, fading dorsomedially. Lateral surface of pronotum foveate. Dorsal pronotal area smooth with minute punctures. Mesoscutum deeply foveate, setose; notaulices complete, extending to anterior margin of mesocutum; median mesoscutal impression reduced to small notch on posterior margin of mesoscutum (Fig. 25D). The two scutellar foveae simple, smooth, with a few setae, separated by scutellar ridge; scutellum entirely foveate, evenly setose (Fig. 25D). Posterior mesoscutum and scutellum contiguously rounded in lateral view. Mesopleural triangle defined by ventral curved carina, strongly pubescent; upper mesopleuron glabrous, smooth, anteriorly and ventrally pubescent with distinct punctures; median longitudinal impression well developed, with evenly spaced transverse carinae; speculum glabrous, smooth (Fig. 25C).
Metanotal-propodeal complex strongly excavated, excavations bordered by strong carinae. Metepisternum dorsally excavated with pubescence, medially polished, ventrally pubescent. Dorsellum with two strong medial foveae; laterally strongly excavated with fine pubescence in lateral depressions. Lateral propodeal carina present, curved medially; median longitudinal propodeal carina well-defined, crossed by wrinkled transverse and longitudinal carinae extending onto nucha. Rs+M of forewing defined, but nebulous where it arises from basal vein at posterior third (Fig. 25B). Marginal cell 2.5 times as long as wide. Abdominal petiole short, longitudinally striate, 0.25 times as long as wide in dorsal view (Fig. 25F). Posterior ventral margin of metasomal T6 gently sinuate. T7 with a linear patch of long setae anteriorly, completely covering T8, except for a small protrusion that has a distinct basket-like tuft of setae (Fig. 25F). Ventral portions of T2-T7 covered by sternum 3. Tergites dorsally finely punctate; laterally and ventrally polished. All legs sparsely punctuate, strongly pubescent, except metacoxae dorsally glabrous, smooth (Figs 25A, 25F). Mesotibial outer spur shorter than inner spur; metatibial spurs subequal in length. Ratio of first metatarsomere to the remaining 4 metatarsomeres combined: 0.60.
MALE. Unknown.
