Diagnosis.

Stenarella lissonota can be distinguished from all other Stenarella species by the combination of the following characters: mandible smooth or shallowly punctate at basal half; pronotum only with short striae at pronotal depression, elsewhere smooth (Fig. 14 E View Figure 14 , 22 C View Figure 22 ); mesoscutum mostly smooth and shiny (Fig. 14 E View Figure 14 ); notaulus narrow with shallow, dense, and minute transverse keels (Fig. 14 E View Figure 14 ); posterior area of propodeum transversely strigose, tending to be rugulose laterally (Fig. 2 C View Figure 2 ); thyridium about 2.0 times as long as wide; mesosoma mostly orange (Figs 14 D, E View Figure 14 , 22 C View Figure 22 ). Additionally, males can be distinguished by head mostly whitish and by front and mid coxae whitish (Fig. 22 C View Figure 22 ).

Description.

FEMALE. Fore wing 7.5–9.2 mm long. — Head (Fig. 14 A, B, D, E View Figure 14 ): Mandible, clypeus and face moderately setose. Mandible mostly sparsely punctate, MLW 2.1–2.3. Malar space short, MSM 0.35–0.45. Clypeus smooth, CWL 2.9–3.0. Clypeus and face centrally mostly flat. Face centrally weakly wrinkled, elsewhere smooth. Frons shiny, granulate and wrinkled medially, with interrupted longitudinal carina. Antenna with 34 flagellomeres. — Mesosoma (Figs 2 C View Figure 2 , 14 A, C – E View Figure 14 ): Pronotum with distinct striae along anterior depression, elsewhere smooth. Epomia moderately strong, reaching pronotal depression. Mesoscutum mostly smooth and shiny, except anterior part of mid lobe with shallow dense punctures. Notaulus reaching 0.70 of mesoscutum with short transverse striae. Scutellum with sparse, large shallow punctures. Mesopleuron and metapleuron moderately setose. Mesopleuron dorsally rugulose – striate, ventrally finely rugulose. Epicnemial carina distinct, reaching 0.7 of distance to subtegular ridge. Sternaulus shallow and sinuous, reaching posterior rim of mesopleuron. Metapleuron rugulose strigose. Propodeum relatively long, dorsal profile in lateral view evenly convex and sloped. Anterior area of propodeum rugulose punctate. Propodeal spiracle elliptic, SLW 2.0. Posterior area of propodeum transversely strigose, tending to be rugulose laterally. Posterior transverse carina of propodeum present but weakly discernible from other transverse striae, distance to anterior transverse carina 1.5 times the distance from anterior carina to anterior margin of propodeum 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 2.0–2.4. — Metasoma (Fig. 14 A, F View Figure 14 ): Posterior end of S 1 placed posteriorly to spiracle of T 1. T 1 LW 3.1–3.25; T 1 WW 1.7–2.0; T 2 LW 1.3–1.45; T 2 WW 2.25–2.4. Thyridium about 2 times as long as wide. T 2 punctate reticulate on a granulate background, anterior part granulate. Dorsal valve of ovipositor with 5 teeth. Ventral valve with 10 teeth. OST 4.1–5.1. — Color (Figs 2 C View Figure 2 , 14 View Figure 14 ): Head mostly black: clypeus, mandibles except teeth, and facial orbits as a hue, orange; f 6 – f 12 dorsally white f 5, f 13 partially. Mesosoma mostly orange; propleuron and anterior part of pronotum dark brown. Wing hyaline. Metasoma mostly black: T 1 dark brown, T 1 – T 2 and T 5 – T 8 posteriorly whitish. — MALE (Fig. 22 C View Figure 22 ). Fore wing about 6.9 mm long. — Head. Mandible moderately punctate, MLW 2.4. Malar space moderately long, MSM 0.5. CWL 2.6. Antenna with 31 flagellomeres; tyloids on f 13 – f 16. — Mesosoma. Pronotum with very weak and short striae along anterior depression, elsewhere smooth. Anterior area of propodeum rugulose punctate laterally, shallowly punctate medially. SLW about 2.3. Posterior area of propodeum finely and shallowly transversely strigose granulate medially, tending to be rugulose laterally. Areolet very small, APH 0.35. Hind wing vein Cua distinctly longer than crossvein cu-a, HW 1 C about 1.8. — Metasoma. Posterior end of S 1 placed far posteriorly to spiracle of T 1. T 1 LW 4.3; T 1 WW 1.4; T 2 LW 2.8; T 2 WW 1.8. Thyridium about 2.7 times as long as wide. — Color. Head mostly whitish; mandible teeth, frons and vertex except eye orbits, posterior dorsal part of gena and occiput dark brown to black; f 10 – f 15 dorsally white, f 16 partially. Mesosoma mostly orange; dorsal part of pronotum, subtegular ridge, speculum and sternum, yellowish; metapleuron ventrally dark brown. Front and mid coxae and trochanters, hind trochanter and hind t 2 – t 4, whitish. Hind leg mostly dark brown. Wing slightly infuscate. Metasoma mostly dark brown to black; T 1 – T 3 and T 6 – T 8 posteriorly whitish. Other characters as in female.
