Stenarella tripartita View in CoL : Townes and Townes (1973).

Diagnosis.

Stenarella tripartita can be distinguished from all other Stenarella species by the combination of the following characters: vertex densely punctate (Fig. 19 D View Figure 19 ); mesoscutum densely and coarsely punctate on a granulate background (Fig. 19 D View Figure 19 ); propodeum relatively long, dorsal profile in lateral view evenly convex and sloped (Fig. 19 B View Figure 19 , 22 D View Figure 22 ); areolet closed, vein 2 m-cu antefurcal to vein 3 rs-m (Fig. 19 E View Figure 19 ); genal orbit completely yellow (Fig. 19 A, B View Figure 19 , 22 D View Figure 22 ) mesosoma mostly orange, subtegular ridge yellow (Fig. 19 A, B View Figure 19 , 22 D View Figure 22 ).

Description.

FEMALE. Fore wing 6.5–10.5 mm long. — Head (Fig. 19 A – D View Figure 19 ): Mandible, clypeus and face moderately setose. Mandible weakly striate, MLW 1.85–2.2. Malar space short, MSM 0.4–0.45. Clypeus sparsely punctate CWL 2.7–2.9. Clypeus and face centrally mostly flat. Face centrally distinctly wrinkled, elsewhere granulate – punctate. Frons densely punctate, with complete longitudinal carina Vertex densely punctate on a smooth or finely granulate background. Antenna with 32–33 flagellomeres. — Mesosoma (Figs 1 E View Figure 1 , 19 A, B, D, E View Figure 19 ): Pronotum covered by uniform longitudinal striae, dorsal lateral part densely punctate. Epomia strong, reaching pronotal depression. Mesoscutum coarsely and densely punctate on a granulate background, with strong rugae between posterior part of notauli. Notaulus reaching 0.75 of mesoscutum, with strong transverse striae. Scutellum densely punctate. Mesopleuron and metapleuron moderately setose. Mesopleuron dorsally rugulose – striate, ventrally finely rugulose. Epicnemial carina weak (better seen in ventrolateral view), reaching 0.6 of distance to subtegular ridge. Sternaulus shallow and sinuous, reaching anterior 0.7–0.8 of mesopleuron. Metapleuron rugulose punctate. Propodeum relatively long, dorsal profile in lateral view evenly convex and sloped. Anterior area of propodeum rugulose punctate. Propodeal spiracle elliptic, SLW 2.5–3.0. Area between anterior and posterior transverse carina rugulose. Posterior area of propodeum strongly rugulose dorsally, reticulate rugose laterally. Posterior transverse carina of propodeum distinct and complete, distance to anterior transverse carina 2.0 times the distance from anterior carina to anterior margin of propodeum. Areolet closed distally by an unpigmented vein 3 rs-m, APH 0.45–0.55. Vein 2 m-cu antefurcal to vein 3 rs-m. Hing wing vein Cua distinctly longer than crossvein cu-a, HW 1 C 2.75–2.8. — Metasoma (Fig. 19 A, F View Figure 19 ): Posterior end of S 1 placed anteriorly or approximately opposite to spiracle of T 1. T 1 LW 2.3–2.35; T 1 WW 2.7–2.85; T 2 LW 0.95–1.1; T 2 WW 2.1–2.15. Thyridium about 2 times as long as wide. T 2 minutely punctate reticulate on a granulate background, anterior part granulate. Dorsal valve of ovipositor with 5 teeth. Ventral valve with 9 teeth. OST 2.3–3.4. — Color (Figs 1 E View Figure 1 , 19 View Figure 19 ): Head mostly black, often orange posteriorly to ocelli; clypeus, labrum, mandibles except apex, facial frontal and genal orbits and scape ventrally, whitish; f 7 – f 10 dorsally and f 6 and f 11 partially, white. Mesosoma mostly orange; dorsal margin of pronotum, subtegular ridge, whitish; propleuron, mesosternum and metasternum dark brown. Legs mostly dark orange to dark brown; fore coxa posteriorly and all trochanters ventrally, whitish; hind coxa, with dorsal orange stripe; hind t 2–4 dorsally white. Wing hyaline. Metasoma mostly black: T 1 brown; T 1 – T 2 and T 5 – T 8 posteriorly whitish. — MALE (Fig. 22 D View Figure 22 ). Fore wing 5.3–8.3 mm long. — Head: MSM 0.45–0.5. CWL 3.2. Antenna with 30–32 flagellomeres; tyloids on f 12 (13) – f 15 (16). — Mesosoma: SLW 3.5–3.65. APH 0.35–0.45. Vein 2 m-cu antefurcal or interstitial to vein 3 rs-m. HW 1 C 1.85–2.0. — Metasoma: Posterior end of S 1 placed anteriorly or approximately opposite to spiracle of T 1. T 1 LW 4.45–5.3; T 1 WW 1.45–1.75; T 2 LW 2.4–3.3; T 2 WW 1.8–1.9. — Color: As in female. Flagellum without white band. Fore and mid coxa extensively and all trochanters ventrally white; all tarsi dark brown. Other characters as in female.
