Comment: The previously known distribution of A. angularis was confined to West Bengal (ASSING 2015, 2016b). The above specimens represent the first records from Assam and Meghalaya. The species is distinguished from the similar sympatric and syntopic A. cameroni by less distinctly bicoloured legs, usually uniformly reddish segments III–lV (usually infuscate posteriorly or postero-laterally in A. cameroni ), a distinct sexual dimorphism of the head (male head distinctly impressed), and primary sexual characters of different shapes.
