DIAGNOSIS. — This species is closer to T. flaviventris but differs from it in the following combination of character states. In T. flaviventris frons predominantly smooth, hyperoccipital carina present, occiput smooth and mesoscutum smooth, IOS half the width of head and subequal to eye length, T2 wider than long, entirely smooth; whereas in T. ekadanta n. sp. frons laterally and ventrally reticulate, occipital carina invaginate as an inverted ‘v’ shaped carina, hyperoccipital carina absent, occiput and mesoscutum coriaceous reticulate, IOS at most 0.35 × width of head and at most 0.65 × eye length, T2 at least 1.4 × as long as wide, with short striae on anterior margin.

ETYMOLOGY. — This species is named ‘ekadanta’ after the Hindu God Lord Ganesha. The name is treated as a noun in the genitive case.
