Carinityla punctulata Sheng & Sun sp. n. Figures 1-9

Etymology.

The name of the new species is based on the dense punctures on the head and thorax.

Mesoscutum with dense elongate punctures. Notaulus present on front portion of mesoscutum. Scutoscutellar groove with very weak longitudinal wrinkles. Scutellum slightly convex, with irregular punctures. Postscutellum concave, smooth. Subalar prominence strongly convex. Anterior and upper margins of mesopleuron with fine punctures; median portion of mesopleuron (Figure 5) with irregular transverse punctures; speculum with dense and fine punctures. Epicnemial carina broken above sternaulus, upper end of lower portion connecting with short transverse carina opp osite lower corner of pronotum; upper portion of epicnemial carina oblique, upper end reaching about half distance to subalar prominence. Metapleuron with dense punctures, distance between punctures 0.2 to 0.5 times diameter of puncture. Juxtacoxal carina complete. Anterior portion of submetapleural carina strongly lobed. Wings brownish hyaline. Fore wing with vein 1cu-a slightly distal of 1-M by less than vein width. Vein 2-Cu approximately 2.0 times as long as 2cu-a. Hind wing vein 1-cu about 3.0 times as long as cu-a. Legs robust, with dense brown hairs. Hind coxa and femur with distinct fine punctures. Spurs of hind tibia about half length of first tarsomere. Ratio of length of hind tarsomeres 1:2:3:4:5 is 10.0:4.5:3.5:1.8:3.7. Propodeum (Figure 6) with sandy beige long hairs. Area superomedia hexagonal, 1.2 times as wide as long, costula connecting slightly in front of its middle. Area basalis smooth, vaguely punctate. Area externa with distinct punctures. Area superomedia with indistinct longitudinal wrinkles. Area dentipara with oblique longitudinal wrinkles. Area lateralis with oblique transverse wrinkles. Area petiolaris with transverse wrinkles. Propodeal spiracle approximately 3.3 times as long as wide, almost touching lateral longitudinal carina (closer to lateral longitudinal carina than to pleural carina). Propodeal apophysis short and compressed.

Metasoma.

First and second terga smooth and shining, with very sparse and fine punctures. First tergum about 2.3 times as long as apical width. Postpetiole evenly convex. Median dorsal carinae absent. Dorsolateral and ventrolateral carinae complete. Spiracle circular, very small, slightly convex, located at apical 0.4 of first tergum. Second tergum 0.5 to 0.6 times as long as apical width. Remaining terga with short brown hairs. Ovipositor sheath approximately 0.95 times as long as hind tibia. Ovipositor compressed, with weak nodus.

Color

(Figure 1). Black, except the following. Ventral side and apical portion of scape, apical portion of pedicel, ventral side of basal portion (more or less) and flat side of flagellomeres, tegula brown. Dorsal sides of seventh to thirteenth flagellomeres white. Median portion of mandible, dorsal sides of front and mid femora and tibiae brown. Maxillary and labial palpi, fore and mid coxae, trochanters and ventral sides of femora yellowish brown. Fore and mid tarsi dark brown. Hind coxa brown to yellowish brown. Hind trochanter, femur and tibia reddish brown. Apical ends of hind femur and tibia, hind first tarsomere brownish black. Hind second to fifth tarsomeres blackish brown.
