Journal of Insect Biodiversity and Systematics, 4(3), 157–162. Introduction Shuckard (1837) described the genus Celia this paper one new species, namely based on the type species Celia troglodytes Spilomena keralaensis Rajan, Sureshan & (Van der Linden, 1829) and later Girish Kumar sp. nov. is described from (Shuckard, 1838) substituted the name as the Pandimotta shola of Shendurney Spilomena. This genus is distributed in all Wildlife Sanctuary of Southern Western zoogeographical realms with a total of 87 Ghats of Kerala and differences from species worldwide of which 9 species from similar species are given. the Oriental Region and one species from the Indian subcontinent (Pulawski, 2018). Material and methods The only species from the Indian This study is based on the specimens subcontinent S. indostana Turner, 1918, is collected from the Pandimotta shola of described from Bombay, India. This species Shendurney Wildlife Sanctuary of makes their nests in twigs, timber, decayed Southern Western Ghats of Kerala. It is the wood, buildings, etc. (Bohart & Menke, highest place within the sanctuary (1300 m) 1976; Turillazzi et al., 2014). The prey are with a unique shola forest ecosystem. The thrips, psyllids, coccids, aphids, etc. specimens were studied and photographed (Krombein, 1956; Beaumont, 1964).
