Etymology.

Named after hymenopterist Tapani Hopkins ( ZMUT), who collected the type specimens of this species during many months of tireless fieldwork in Uganda. Noun in genitive case.

Diagnosis.

Stenarella hopkinsi sp. nov. can be distinguished from all other Stenarella species by the combination of the following characters: pronotum and mesoscutum smooth and shiny (Fig. 11 B, D View Figure 11 ); anterior area of propodeum coarsely rugose punctate; posterior area of propodeum transversely striate, striae regularly separated and reaching pleural sulcus (Fig. 1 J View Figure 1 ); face and facial orbits black (Fig. 11 C View Figure 11 ); antenna with white band on f 6 – f 11 (12) (Fig. 11 A View Figure 11 ); mesoscutum black (Fig. 11 D View Figure 11 ); mesopleuron, metapleuron and propodeum dark orange to brownish orange (Fig. 11 B View Figure 11 ); hind coxa black (Fig. 11 A View Figure 11 ).

Description.

FEMALE. Fore wing about 13.7 mm long. — Head (Fig. A – D): Mandible covered with very dense and long setae. Clypeus and face moderately setose. Mandible punctate or slightly striate at basal half, MLW 2.0–2.2. Malar space short, MSM 0.40–0.45. Clypeus smooth, CWL 2.75–3.0. Clypeus and face flat. Face centrally distinctly rugulose, elsewhere smooth or slightly granulated. Frons smooth and shiny, sometimes slightly rugulose behind antennal sockets, with weak interrupted longitudinal carina. Antenna with 36 flagellomeres. — Mesosoma (Figs 1 J View Figure 1 , 11 A, B, D, E View Figure 11 ): Pronotum almost entirely smooth and shiny, punctate at dorsal medial part, weakly longitudinally striate at ventral part of pronotal depression. Epomia strong, reaching pronotal depression. Mesoscutum almost entirely smooth and shiny with coarse convergent rugae between posterior end of notauli. Notaulus reaching 0.85 of mesoscutum with fine transverse striae. Scutellum mostly punctate with central part smooth. Mesopleuron and metapleuron moderately setose. Mesopleuron very densely and finely punctate, dorsally with weak longitudinal rugae. Epicnemial carina distinct, reaching 0.8 of distance to subtegular ridge. Sternaulus moderately deep and sinuous, almost reaching posterior rim of mesopleuron. Metapleuron densely punctate rugulose. Propodeum relatively long, dorsal profile in lateral view evenly convex and sloped. Anterior area of propodeum coarsely rugose punctate. Propodeal spiracle elliptic, SLW 2.65–2.8. Posterior area of propodeum covered by more or less uniformly spaced transverse striae. Posterior transverse carina of propodeum indiscernible from transverse striae. Areolet very small, closed distally by an unpigmented vein 3 rs-m, APH 0.30–0.35. Vein 2 m-cu antefurcal to vein 3 rs-m. Hind wing vein Cua distinctly longer than crossvein cu-a, HW 1 C 2.7–2.85. — Metasoma (Fig. A, F): Posterior end of S 1 placed posteriorly to spiracle of T 1. T 1 LW 2.7–3.1; T 1 WW 2.3–2.45; T 2 LW 1.20–1.4; T 2 WW 2.1–2.15. Thyridium about 1.8–2.2 times as long as wide. T 2 mostly minutely densely punctate reticulate on a finely granulate background, anterior part only finely granulate. Dorsal valve of ovipositor with 5 teeth. Ventral valve with 10 teeth. OST 3.4–3.60. — Color (Fig. 1 J View Figure 1 , 11 View Figure 11 ): Head mostly black: labrum, clypeus, mandible except distal part, mouth parts, widely frontal orbits, narrow spot on dorsal part of genal orbit and f 6–11 (12) dorsally, whitish. Mesosoma mostly dark orange to brownish orange: propleuron, pronotum, mesoscutum, anterior part and widely median part of propodeum, dark brown to black; small spot on dorsal posterior part of pronotum, subtegular ridge, lateral parts of scutellum and posterior medial wide spot on propodeum, whitish. Legs mostly orange; fore and mid coxae and trochanters partially dark brown and whitish, tarsi dark brown; hind leg dark brown; t 1 posteriorly, t 2 – t 4, and distal part of t 5, yellowish. Wing hyaline. Metasoma dark brown; T 1 – T 2 narrowly and T 6 – T 7 extensively, posteriorly whitish. — Male. Unknown.
