Colour. Body predominantly black; antenna, mandible, tegula; pterostigma, wing veins, coxae and metasoma dark brown; maxillary and labial palps, legs (except coxae) yellow.
Male. Unknown.
Distribution.
India.
Etymology.
The new species is named after our field assistant Mr. Thamilselvan, whom we fondly call ‘ Chian’, who contributed much in establishing insect collection from the difficult terrain of KMTR.
Comparative diagnosis.
Apart from the differences given in the key, the new species differs from M. gowrishankari sp. nov. by the following characters: head 1.6 × as wide as long in anterior view (1.3 × in M. gowrishankari sp. nov.), face 1.7 × as wide as long (2.4 × in M. gowrishankari sp. nov.), epicnemial area with complete groove behind epicnemial carina (incomplete in M. gowrishankari sp. nov.) and area dentipara of propodeum longer than wide (wider than long in M. gowrishankari sp. nov.).
