Etymology.

Named after Bugala Island, where the paratype was collected. From the Latinized adjective bugalanus, - a, - um.

Diagnosis.

Stenarella bugalana sp. nov. can be distinguished from all other Stenarella species by the combination of the following characters: mandible punctate at basal half; pronotum mostly with distinct and coarse longitudinal striae (Fig. 5 C); mesoscutum mostly smooth and shiny (Fig. 5 D); posterior area of propodeum transversally strigose (Fig. 2 D); posterior end of S 1 placed distinctively posterior to spiracle of T 1 (Fig. 5 A); thyridium about 2.5 times as long as wide; base of mandible dark orange to dark brown (Fig. 5 B); T 1 dark brown (Fig. 5 A); wing hyaline or evenly infuscate (Fig. 5 E).

Description.

FEMALE. Fore wing 8.0– 8.7 mm long. — Head (Fig. 5 A – D): Mandible, clypeus and face moderately setose. Mandible punctate, MLW 2.05–2.2. Malar space short, MSM 0.4–0.45. Clypeus sparsely punctate, CWL 2.6–2.75. Clypeus and face centrally mostly flat. Face centrally distinctly wrinkled, elsewhere sparsely punctate on a granulate background. Frons shiny, granulate and sparsely punctate, with interrupted longitudinal carina. Antenna with 32 flagellomeres. — Mesosoma (Figs 2 D, 5 A, C – E): Pronotum with distinct longitudinal striae, median dorsal part smooth. Epomia strong, reaching pronotal depression. Mesoscutum mostly smooth and shiny, except for anterior part of mid lobe with shallow dense punctures. Notaulus reaching 0.75 of mesoscutum, with short transverse striae. Scutellum rugulose. Mesopleuron and metapleuron moderately setose. Mesopleuron dorsally rugulose striate, ventrally finely rugulose. Epicnemial carina distinct, reaching 0.6 of distance to subtegular ridge. Sternaulus deep evenly upcurved, reaching anterior 0.7 of mesopleuron. Metapleuron rugulose strigose. Propodeum relatively long, dorsal profile in lateral view evenly convex and sloped. Anterior area of propodeum finely rugulose punctate. Propodeal spiracle elliptic, SLW 2.2–2.5. Posterior area of propodeum transversally strigose. Posterior transverse carina of propodeum absent. Areolet small, closed distally by an unpigmented vein 3 rs-m, APH 0.50–0.55. Vein 2 m-cu antefurcal to vein 3 rs-m. Hind wing vein Cua distinctly longer than crossvein cu-a, HW 1 C 1.85–2.15. — Metasoma (Fig. 5 A, F): Posterior end of S 1 placed distinctively posterior to spiracle of T 1. T 1 LW 3.0–3.1; T 1 WW 2.25–2.30; T 2 LW 1.4–1.45; T 2 WW 2.55–2.60. Thyridium about 2.5 times as long as wide. T 2 mostly minutely punctate reticulate on a granulate background, small anterior dorsal portion granulate. Dorsal valve of ovipositor with 5 teeth. Ventral valve with 7 teeth. OST 4.4–4.6. — Color (Figs 2 D, 5): Head dark brown to black: labrum, facial and frontal orbits and genal orbit dorsally, whitish. Antenna with f 6 – f 11 (12 proximally) dorsally white. Mesosoma mostly dark orange: pronotal collar dark brown; propleuron, mesosternum and metasternum black. Fore and mid legs mostly dark orange with coxae, trochanter and trochantellus, dark brown, tarsi darkened or entirely dark brown. Hind leg dark brown. Wing hyaline or evenly infuscate. Metasoma mostly black; T 1 mostly orange-brown; T 1 – T 2 narrowly and T 5 – T 7 extensively, posteriorly whitish. — Male. Unknown.
