Citation: Quicke DLJ, Broad GR, Areekul Butcher BA (2012) First host record for the Palaeotropical braconine wasp genus Cassidibracon Quicke (Hymenoptera, Braconidae) with the description of a new species from India. Abstract A new species, Cassidibracon gracillariae Quicke sp. n. from India, is described and illustrated and differ-entiated from other Indian species. The three known specimens were each reared from distinctive, exposed, bubble-coated cocoons of the gracillariid moth Stomphastis chalybacma (Meyrick, 1908), which superfi-cially resemble insect egg clusters. This is the first reported host record for the genus Cassidibracon Quicke.
