Abstract

Two new species of the genus Psechrus Thorell, 1878, are described from northeastern states of India: P. chizami sp. nov. (female) and P. nathanael sp. nov. (male, female). Detailed morphological descriptions, diagnoses, photos, and illustrations of the copulatory organs are provided along with the updated distribution of Psechrus species in India.
