D e s c r i p t i o n o f n e w ♁: Body length 5.0 mm. Flagellum slender, with 35 segments; 1 st flagellar segment 5.0× as long as wide, 1.4× as long as 2 nd segment and 0.67× as long as eye. Temple shortly parallel behind eye and moderately narrowed apically, dorsally 1.1× as long as eye. Distance between lateral ocellus and eye 1.1× ocellar diameter. Face coarsely punctate, partly rugose-punctate, sides ± parallel, width 1.2× combined length of clypeus and face and 1.0× eye length. Mandible with two teeth, ventral tooth slightly larger than dorsal tooth. Ventral 0.5 of facial orbit coarsely striate. Malar space 0.6× as long as width of mandibular base.

Mesoscutum with fine sparse punctures, shiny. Mesopleuron with fine rather dense punctures dorsally and fine sparse punctures ventrally. Area basalis rectangular, c. 1.5× as long as wide. Area superomedia 1.8× as long as wide and 1.0× as long as area petiolaris; costula reaching at 4/10 of its length. Area petiolaris 1.2× as long as wide. Hind femur 4.2× as long as wide. Hind claws with c. 6 long dense teeth. Areolet pointed frontally, oblique (e.g. vein 3rs-m 1.5× as long as 2rs-m); vein 2m-cu reaching its middle. Vein 1cu- a interstitial. Pterostigma c. 3.0× as long as wide. 1 st tergite 2.9× as long as wide; postpetiole smooth. 2 nd tergite 1.1× as long as wide. Thyridium oval. Stylet of paramere 0.73× as long as hind metatarsus, distinctly clubbed apically and slightly bent upwards.

Color: black. Flagellum black. Head black; palps, mandible basally and malar space ivory; clypeus and face reddish-brown, face with two paramedian longitudinal blackish stripes; orbits widely red. Mesosoma black; mesoscutum with H-shaped reddish central spot; hind edge of pronotum, tegula and wing base ivory. Tergites black; 2 nd and following tergites with narrow ivory apical margins; 3 rd and 4 th tergite ochreous medially, brownish laterally. Legs reddish; hind coxa black; hind tibia narrowly black basally, not infuscate apically; distal tarsomeres of all legs brownish. Wings hyaline; pterostigma brown.

R e m a r k s This ♁ runs to couplet 63(64) M. pectinipes BRIDGMAN in the key of Mesochorus ♁♁ ( SCHWENKE 1999: 115-118). It differs by its longer and wider temple, oblique areolet of fore wing, stouter paramere, smooth postpetiole and ivory apical margins of 2 nd and following tergites.
