Venkitesan leg. Kimmins (1958) described Protosticta rufostigma from the Odonata collections of the British Museum of Natural History. The specimens ( 1 ♂ and 2 ♀♀ ) used in the description were collected from Naraikadu, Tirunelveli (= Tinnevelly), Tamil Nadu (South India ) during the month of September 1938 by G.M. Henry. Recently, the Zoological Survey of India , Southern Regional Centre has been surveying the Western Ghats of Tamil Nadu to document the odonate fauna of Kanyakumari Wildlife Sanctuary, Kanyakumari ( Fig. 23b ). While studying the collections, we identified a specimen as belonging to P. rufostigma , which has not been recorded since the species description. This species is distinguished from its close relative P. davenporti , by a combination of following characters: a) central portion of posterior lobe of prothorax black ( Fig. 20 c–d), sides brown (posterior lobe fully black in P. davenporti , Fig. 21 a–b); b) larger pterostigma ( Fig. 20h ); c) outer fork of cerci less than twice the length of inner fork (more than twice the length in P. davenporti ); and d) outer fork of cerci squared at apices ( Fig 20 e–g; rounded in P. davenporti , see Fig. 22 ). Nodal index: 14 in all wings. Measurements: abdomen + caudal appendages = 44.4, FW = 24.2, HW = 24, cerci = 1.2, paraprocts = 0.8.
