It is clear that further study of this group from the study area would explore more interesting species. INTRODUCTION The members of the family Staphylinidae are Mizoram is one of the states of Northeast India, commonly known as rove beetles and one of the with Aizawl as its capital. The name is derived largest family of the superfamily Staphylinoidea from Mi, Zo and Ram, and thus Mizoram implies distributing throughout the world. 30,000 species “land of the hill people” Mizoram is located are known from the world of which more than between 23.1645° N and 92.9376° E . The tropic 3000 species are recorded so far from India. of Cancer passes near the capital, Aizawl town. The pioneer workers who dealt the group are Mizoram occupies the north east corner of India. Motschulsky (1858), Kraatz (1859), Fauvel (1895) It is bounded by the state of Assam on the north and Bernhauer (1915) etc. Prior to Camerons work and the state of Manipur, on the east and south on the fauna of British India Series (1930,1931, by Chin Hills and Arakan (Myanmar), and on the 1932). Since the work of Cameron (1930-45), west by the Chittagong hill tracts of Bangladesh no comprehensive work on Indian fauna of and the state of Tripura. Mizoram borders three Staphylinidae have been done by any author. states of India - Assam, Manipur and Tripura. Its The present work on the family Staphylinidae: geographical borders are with Assam, Manipur Paederinae is based on the collections brought and Tripura extended over 123 km, 95 km and 66 from different districts of Mizoram by various km, respectively. Mizoram is a land of hills. The survey parties of Zoological Survey of India, and hills run in ridges from north to south. They have other oldest collectios present in the National an average height of 900 meters, the highest point Zoological collection. Materials of some species being the Blue Mountain 2165 meter. Mizoram is recorded from Mizoram were not available for a land of unending natural beauty with a variety of study, however for the sake of completeness, these flora and fauna. Mizoram can boast of a variety species are also included in this work.
