Association with antlions and the peculiar mode of oviposition makes the genus more interesting. Here we describe and illustrate a new species of Lasiochalcidia Masi with a key to Oriental species.

Received: 11 July 2019; Revised: 26 December 2019; Online: 31 December 2019 Introduction Lasiochalcidia Masi, 1929 is one of innate ability to discover hidden hosts by the least common genera of hybothoracine perceiving the movements on loose soil made (Haltichellinae: Hybothoracini) tribe to occur by the antlion larva, using the specialised in any collection from the tropics. Presently mechanoreceptors on the antennae. The female constituting of 23 species worldwide, the parasitoid provokes the antlion larva to attack species is mostly associated as parasitoids of its hindlegs with the powerful and deadly antlion larvae (Neuroptera: Myrmeleontidae) mandibles of antlion larva.
