Keesia Mitroiu , gen. nov.
( Figs 1–4 View FIGURE 1 View FIGURE 2 View FIGURE 3 )
Etymology. The new genus is dedicated to Dr. Cees (Kees) van Achterberg, world specialist of Braconidae , who collected one of the specimens. The name is of feminine gender.
Type species: Keesia dorsellata Mitroiu , sp. nov., designated here.
Diagnosis. Clypeal margin broadly emarginate; antenna with all five funicular segments anelliform; dorsellum flat and large, longer than propodeum; fore wings bare except for marginal fringe and a few lines of hairs; M long, S and P very short.
Description. Body black or brownish-black, without metallic reflections except sometimes the head, which can be slightly bluish. Head, mesosoma and metasoma smooth, with several long setae.
Head from about as high as wide to clearly higher than wide. Clypeal margin broadly emarginate in middle. Right mandible with 4 teeth. Eyes moderately pilose, oval. Toruli distinctly below lower eye margin. Antenna with anelli inconspicuous, the five funicular segments anelliform, increasing in diameter, and without sensilla. Clava large.
Mesosoma from almost flat to moderately convex. Pronotum short or moderately long, not margined. Notauli deep and complete. Scutellum flat or slightly convex; frenal line sinuate, frenum smooth. Dorsellum shiny, its central part semicircular and almost horizontal, longer than propodeum, its hind margin slightly extending above the base of the latter (best seen in profile). Propodeum shiny, without raised median carina. Hind coxa bare. Pecten present on the inner side of hind tibia at least in one species. Tarsi 5-segmented. Fore wings narrow, hyaline, almost bare except for marginal fringe and some rows of hairs (‘macrotrichia’) along the obsolete cubital and r-m veins (as defined by Burks 1938); M long, S and P very short, with S perpendicular on M.
Metasoma sessile, oval, laterally compressed. Some metasomal tergites larger than others or subequal in size. Hypopygium reaching from about 2/3 length of metasoma to near its tip. Ovipositor sheaths slightly protruding.
Male and biology. Unknown.
Putative autapomorphies:
1. Broadly emarginate clypeal margin ( Fig. 1 View FIGURE 1 ) — only two species of Macroglenes ( M. incisiclypeatus Mitroiu and M. zdeneki Mitroiu ) have an incised clypeus, but the incision is very small compared with the broad emargination found in Keesia ;
2. Very long and flat dorsellum, longer than propodeum ( Fig. 2 View FIGURE 2 ) — not present in any other pteromalid genus; 3. Reduced wing pilosity, with fore wings being also narrower than usual ( Fig. 3 View FIGURE 3 ) — a condition extremely rare within Pteromalidae , previously never found in Pireninae .
