ABSTRACT.A survey of Acridid fauna in totally different habitats in different regions of Haryana state was carried out during the period from 2009 to 2011. Thirty six species were captured belonging to twenty three genera and eight subfamilies. Oedipodinae (28%) was the most dominant subfamily. Spathosternum prasiniferum prasiniferum (Walker, 1871) was found to be most abundant.

The paper deals with a new record Hexacentrus japonicus Karny, 1907 and a new species Hexacentrus bifurcata sp. nov. from India. Necessary and important illustrations with SEM images of stridulatory file of Hexacentrus japonicus and Hexacentrus bifurcata sp. nov. are provided. A key to the Indian species of Hexacentrus and morphometric ranges of all the species have also been included. Type specimens have been preserved for further investigation in Zoology Department, Aligarh Muslim University (ZDAMU).
