Genus Chondromorpha Silvestri, 1897 View in CoL

The genus Chondromorpha Silvestri, 1897 comprises seven accepted species, with India hosting four. Specifically, C. severini Silvestri, 1897 is found in South India, C. kelaarti Humbert, 1865 in South India and West Bengal, C. kaimura Turk, 1947 in Bihar, and C. mammifera Attems, 1936 along the Orissa Coast, Bombay Presidency, Bihar, and South India. The remaining two species are C. stadelmanni Verhoeff, 1930 , endemic to Sri Lanka, and C. xanthotricha Attems, 1898 , pantropical, but historically uncertain for its presence in India ( Attems 1936; Sankaran and Sebastian 2017), whereas C. greke has been described from Nepal ( Golovatch 2023).

The Indian species of this genus are differentiated based on the number of prominences on their male sterna. One group shows a single prominence, including C. severini and C. kelaarti , while the other group presents a pair and comprises C. mammifera and C. kaimura ( Sankaran & Sebastian 2017) . In Gujarat, two Chondromorpha species have been found for the first time in our study. The presence of the cosmopolitan C. xanthotricha Attems, 1898 in Gujarat confirms its occurrence in India.
