Antenna blackish; head dark yellow except for ocellar triangular area with blackish spot and maxillary palp reddish-yellow; mesosoma reddish-yellow but mesoscutum with blackish-brown spots laterally; propodeum dark brown; fore leg reddishyellow, middle and hind legs blackish-brown; wings membrane infuscated and veins blackish brown; metasomal tergites black; ovipositor sheath blackish-brown.

Variation. Paratypes similar to the holotype. Antenna with 66–69 segments. Head in dorsal view 1.6–1.7 times as broad as long. Hind femur 3.1–3.3 times as long as broad medially. Pterostigma somewhat wide, 3.1–3.2 times as long as wide; second submarginal cell of fore wing long, vein 3-SR 2.2–2.3 times as long as the 2-SR. First tergite 1.1 times as long as broad posteriorly. Second tergite distinctly longer than third tergite. Vertex pale yellow or reddish yellow; mesoscutum with blackish brown spots laterally; middle and hind legs pale yellow; ovipositor sheath yellowish brown.

Biology. Unknown.

Etymology. From latin “grandis” meaning for large, referring to large body of type specimens.

Diagnosis. This species is similar to Atanycolus crenulatus Telenga , but can be separated from the latter by having the length of body more than 10 mm; the wings infuscated (Fig. 5); ocellar triangular area with a blackish spot (Fig. 2); vein 1-SR+M of fore wing slightly bent basally (Fig. 5); propodeum with relatively dense and long setae laterally (Fig. 6); second tergite deeply striate except for smooth medio-basal triangular area (Fig. 7), and third metasomal tergite with a distinctly raised area anterolaterally (Figs 7, 8).
