Carinityla punctulata Sheng & Sun, sp. n.

The name of the new genus is based on the strongly swollen tyloids. The gender is feminine.

Fore wing length 7.2 to 8.8 mm. Head and thorax with dense and comparatively long hairs. Eye surface with short, sparse hairs. Upper margin of face slightly produced, weakly concave medially. Clypeus slightly convex, median portion of apical margin somewhat arcuate and distinctly raised. Mandible elongate, upper and lower margins almost parallel, upper tooth longer than lower tooth. Apical truncation of scape almost transverse. Apical half of antenna strongly flattened below in female. Flagellomeres 10 to 11 (12) of male with strongly swollen tyloids. Epomia long and strong, from lower-anterior angle of pronotum continuing to its dorsal portion (Figure 4). Notauli present. Posterior edge of mesoscutum with transverse groove, which is unusually conspicuous and complete. Scutoscutellar groove without median longitudinal carina. Epicnemium with short transverse carina opposite lower corner of pronotum. Epicnemial carina strongly curved backward or broken (Figure 5) above sternaulus. Anterior half of sternaulus deep; posterior half weak, reaching to posterior margin of mesopleuron above its lower posterior corner. Areolet pentagonal, receiving vein 2m-cu at or slightly basad of its outer corner (Figures 1, 7, 10, 14). Vein 2m-cu subvertical, with one bulla. Hind wing vein 1-cu strongly inclivous, about 3.0 to 4.0 times as long as cu-a. Propodeum completely areolate, carinae very strong. Costula connecting area superomedia in front of its middle. Propodeal spiracle 3.0 to 3.5 times as long as wide. Median dorsal carinae of first tergum absent. Ovipositor compressed, tip very long and gradually tapered, with a weak nodus and very thin and indistinct ridges on ventral valve.

This new genus is similar to Amphibulus Kriechbaumer 1893 and Coptomystax Townes 1970 and can be distinguished from Amphibulus in the notaulus present; epicnemial carina strongly curved backward or secondary carina present above sternaulus; fore wing vein 2m-cu almost reaching 3rs-m (Figure 1, 7, 10, 14). In Amphibulus, the notaulus is absent; the epicnemial carina is neither curved backward nor is there a secondary carina above the sternaulus; fore wing vein 2m-cu is usually far from 3rs-m, usually connecting with the areolet near its median portion. The new genus can be distinguished from Coptomystax Townes by the eye surface with short sparse hairs; the upper margin of face without tubercle; a transverse groove at the posterior edge of mesoscutum distinct, complete and unusually conspicuous; the epicnemial carina approaching the subalar prominence, or discontinuous above the sternaulus. In Coptomystax the eye surface is bare; the upper edge of the face has a high and compressed median tubercle; the transverse groove at the posterior edge of the mesoscutum is distinct medially, evanescent laterally; the epicnemial carina ends below the middle of the hind edge of the pronotum.

This new genus can also be easily distinguished from the related genera Endasys Förster 1869 and Cisaris Townes 1970 by the following combination of characters: scutoscutellar groove without median longitudinal carina, median dorsal carinae of first tergum absent (Endasys: scutoscutellar groove with a median longitudinal carina, first tergum with distinct median dorsal carinae); fore wing with distinct areolet, posterior edge of mesoscutum with transverse groove (Cisaris: fore wing without areolet, posterior edge of mesoscutum without transverse groove).

In Townes’ (1970) key to genera, the new genus can be inserted as follows:

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