Diagnosis.

Stenarella brykella can be easily distinguished from all other species of Stenarella by the mesoscutum mostly granulate without punctures on lateral lobes (Fig. 4 E View Figure 4 ).

Description.

FEMALE. Fore wing 8.5–10.6 mm long. Head (Fig. 4 A, B, D View Figure 4 ): Mandible, clypeus and face moderately covered with very long setae. Mandible punctate, MLW 1.95–2.15. Malar space moderately long, MSM 0.5–0.55. Clypeus sparsely punctate, CWL 2.85–2.9. Clypeus and face centrally mostly flat. Face centrally distinctly wrinkled, elsewhere smooth. Frons shiny, granulate and sparsely punctate, rugulose near vertex, with complete but anteriorly faint longitudinal carina. Antenna with 32 flagellomeres. — Mesosoma (Figs 1 A View Figure 1 , 4 A, C – E View Figure 4 ): Pronotum entirely covered by uniform longitudinal striae. Epomia strong, reaching pronotal depression. Mesoscutum mostly granulate, anterior part with shallow dense punctures. Notaulus reaching 0.75–0.8 of mesoscutum with long and deep transverse striae. Scutellum rugulose punctate. Mesopleuron and metapleuron moderately setose. Mesopleuron mostly finely rugulose granulate, shortly longitudinally strigose along epicnemial carina. Epicnemial carina distinct, reaching 0.6 of distance to subtegular ridge. Sternaulus shallow, evenly upcurved, reaching anterior 0.6 of mesopleuron. Metapleuron strigose – granulate. Propodeum relatively long, dorsal profile in lateral view evenly convex and sloped. Anterior area of propodeum rugulose punctate. Propodeal spiracle elliptic, SLW 1.85–2.0. Posterior area of propodeum finely striate medially, rugulose laterally. Posterior transverse carina of propodeum absent. Areolet small, closed distally by an unpigmented vein 3 rs-m, APH 0.45–0.5. Vein 2 m-cu antefurcal to vein 3 rs-m. Hind wing vein Cua distinctly longer than crossvein cu-a, HW 1 C 1.74–2.05. — Metasoma (Fig. 4 A, F View Figure 4 ): Posterior end of S 1 placed posterior to spiracle of T 1. T 1 LW 2.65–2.7; T 1 WW 1.8–2.2; T 2 LW 1.1–1.55; T 2 WW 2.15–2.55. Thyridium about 2.0 times as long as wide. T 2 mostly finely punctate reticulate, anteriorly granulate. Dorsal valve of ovipositor with 5 teeth. Ventral valve with 9 teeth. OST 4.30–4.45. — Color (Figs 1 A View Figure 1 , 4 View Figure 4 ): Head mostly black; labrum, mandible basally, clypeus laterally facial, frontal and genal orbits (sometimes medially interrupted), f 6 – f 10 dorsally, and f 5 and f 11 partially, whitish. Mesosoma mostly orange: propleuron, pronotum anteriorly, mesopleuron ventrally 0.2, mesosternum and metasternum black; subtegular ridge and dorsal narrow band on pronotum whitish. Legs mostly dark brown; fore coxa dorsally and posteriorly with a white stripe; hind femur mostly orange; hind t 2 – t 3 sometimes white. Wing hyaline. Metasoma dark brown to black. T 5 – T 7 posteriorly whitish banded. — MALE. Unknown.
