Differential diagnosis
The new species, S. manjapulli Ranjith sp. nov. is close to S. siccula by a reddish mesopleuron, pleural carina complete without interruptions, mesoscutum without yellow marks medially. But it differs from S. siccula in having the following differences: antenna with 36 flagellomeres (33 in S. siccula), upper tooth of mandible 1.3 × as long as lower tooth (1.6 × in S. siccula), POL 1.6 × OOL (1.3 in S. siccula), pterostigma 4.8 × as long as wide (3.4 × in S. siccula) and face 1.4 × as wide as long (1.8 × in S. siccula).
Etymology
The species name ‘ manjapulli ’ means ‘yellow spots’ in the Tamil language due to the presence of four isolated yellow spots on the dorsal side of the head. Tamil is the vernacular language of Tamil Nadu State of India, located on the eastern side of the Western Ghats, where the type locality is situated, noun in apposition.
