Dolichomitus excavatus Zwakhals, 2010: 124. Type: male; TD: ZSM.
Description of male. Male. Fore wing 9.0 mm, body 14.5 mm.
Color. Black. Ventral part of antennal scape, palpi and tegula pale yellow. Clypeus brown. Fore and mid legs yellowish brown; all trochanter paler. Hind leg brown except for tibia to tarsus dark brown. Pterostigma yellowish brown. Metasoma dark brown with darkened band apically.
Head: Face densely punctate with long silver hairs (Fig. 3), distance between punctures almost as long as their diameter; face 1.3 × as wide as distance between below antennal socket and above clypeus. Clypeus separated from face by transverse carina; margin of clypeus concave; clypeus 2.6 × as wide as high. Mandible with equal length teeth. Malar space with fine sculpture, 0.2 × as long as basal width of base of mandible. Frons weakly excavated above base of antennae; frons with fine and sparse punctures; vertex sparsely punctate. Diameter of lateral ocellus 0.87 × as long as shortest distance between lateral ocellus and eye. Distance between lateral ocellus and occipital carina about 1.9 × as long as diameter of lateral ocellus. Antenna with 25 + flagellomeres; first flagellomere 3.6 × as long as wide. Temple shiny, distance of temple shorter than transversal diameter of eye in lateral view.
Mesosoma: Mesosoma covered with long silver hairs. Pronotum strongly depressed, upper part of pronotum sparsely punctate; epomia absent. Mesoscutum densely punctate; middle lobe of mesoscutum forms surface an angle less than 90º. Notaulus deep. Epicnemial carina weak, reaching middle of front ridge of mesopleuron. Prepectus densely punctured; mesopleuron with moderately dense punctures. Speculum area concave and glabrous. Mesepimeron glabrous. Scutellum weakly convex, with fine and very sparse punctures, without lateral carinae. Propodeum rugosely punctate, with median longitudinal carinae, slightly transversally striated in apical half. Propodeal spiracle round, closer to pleural carina. Submetapleural carina present. Legs slender. Mid coxa with short, broad tooth and deep excavation on dorso-lateral part (Fig. 9). Hind femur 5.3 × as long as wide. Correlation length of hind tarsal segments as 26:12:9:4:11. Fore wing with areolet; nervulus opposite to basal vein. Nervellus of hind wing intercepted above middle (Fig. 11). Hind wing with seven distal hamuli.
Metasoma: First tergite rugosely punctate, 2.0 × as long as wide at apex; second tergite 2.1 × as long as wide (Fig. 10). Lateral part of first tergite rather coarse and rugose. Second tergite with oblique groove that runs from base near the midline toward the spiracle. Fourth to fifth tergites without lateral swellings. Apex of second to fifth tergites with polished band.
