Fig. 8

This species resembles A. basalis but can be distinguished from it by: 1) subgenital plate distinctly asymmetrical with posterior margin strongly produced at middle, while slightly asymmetrical with posterior margin more or less produced in A. basalis; 2) supra-anal plate with paraprocts nearly identical, distinctly different for A. basalis.

The specific name is derived from the Latin word ‘ niger ’ and refers to the black markings at the base of tegmina.
