The insect order Dermaptera is globally composed of approximately 2,000 species distributed over 245 genera and 16 families, of which approximately 285 species composed within 72 genera and 16 families are known from India until now. A recent examination of some unidentified Dermaptera species housed in the National Zoological Collection of the Zoological Survey of India revealed new state records for six Dermaptera species in India. All the six species are dealt herein with material examined, diagnostic characters, distribution, remarks, and photographs of adult male and female, penultimate sternite and ultimate tergite with forceps, and male genitalia.

The present paper is intended to report four new records of earwigs for the State, Nagaland. The species, Euborellia manipurensis Srivastava, 1979, Chaetospania feae Bormans, 1894, Adiathella metallicus (Srivastava, 1885) and Allodahlia dineshi Gangola, 1965 are reported for the first time from Nagaland. A systematic list of Dermaptera known till date is also provided.
