Rediscovery of Protosticta rufostigma Kimmins, 1958 View in CoL

( Fig. 20 View FIGURE 20 )

Material examined. 1 ♂ ( ZSI-SRC I/OD/2227): Velachithodu , Kaliyal Beat, Kanyakumari Wildlife Sanctuary, Tamil Nadu, India (8.53833 N, 77.311 74 E; Alt. 482 m), 04.iv.2017, R. 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 View FIGURE 23 ). 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 View FIGURE 20 c–d), sides brown (posterior lobe fully black in P. davenporti , Fig. 21 View FIGURE 21 a–b); b) larger pterostigma ( Fig. 20h View FIGURE 20 ); 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 View FIGURE 20 e–g; rounded in P. davenporti , see Fig. 22 View FIGURE 22 ).

Nodal index: 14 in all wings.

Measurements: abdomen + caudal appendages = 44.4, FW = 24.2, HW = 24, cerci = 1.2, paraprocts = 0.8.
