Armature of metascutellum: triangular spine. Sculpture of metanotal trough: weakly foveate. Sculpture of lateral propodeal area: with depressions. Posterior propodeal projection: pointed, directed posteriorly. Sculpture of lateral pronotal area: dorsally with sparse setose protuberances, remainder smooth except for transverse carinae ventrally.

Sculpture of femoral depression: smooth. Mesopleural pit: not distinct. Sculpture of ventral mesopleuron: with setose protuberances interspersed with sparse transverse carinae. Sculpture of metapleuron: dorsally smooth, ventrally setigerous punctate except for a smooth patch posterodorsally. Metapleural sulcus: weakly foveate. Paracoxal sulcus: weakly foveate. Metapleural epicoxal sulcus: not foveate. L:W of fore wing: 79.8:29.2. L:W of hind wing: 72.6:11.4. Marginal cilia on posterior margin of proximal fore wing: absent.

Material examined
Holotype. Female (ICAR / NBAIR / P4488), INDIA: Tamil Nadu: Hosur, Uddanapalli, 12.624°N 77.924°E, 758 m, YPT, 30 January 2015.
Etymology
The species epithet ‘valluvar’ is in honour of Tiruvalluvar, the accomplished Tamil poetsaint of South India who composed the Tirukkural, a secular work on ethics consisting of well over a thousand couplets. The name is treated as a noun in the genitive case.
Diagnosis
Chakra valluvari sp. nov. resembles C. sarvatra but differs from it in the following combination of character states. In C. valluvari, T3 is longitudinally striate, and the setose protuberances on dorsal frons, mesoscutum and metascutellum are spaced apart; whereas in C. sarvatra T3 is smooth with sparse short carinae anteriorly, and the setose protuberances, mesoscutum and metascutellum are closely spaced.
