Diagnosis

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 .

Etymology

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

COLORATION. Body yellowish brown, eyes black, antennae dark brown ( Fig. 8 A–B). Face yellowish brown ( Fig. 8C ). Pronotum yellowish-brown lateral borders of pronotum hyaline ( Fig. 8D ). Two thirds of tegmina yellowish brown, remaining dark brown ( Fig. 8G ). Wings with costal field and appendicular field infuscated, other part pale brown, with veins brown ( Fig. 8H ). Abdominal sterna yellowish brown with black borders; legs pale yellowish brown; cerci brown ( Fig. 8B ).

HEAD AND THORAX. Interocular space greater than distance between antennal sockets ( Fig. 8C ). Fourth and fifth maxillary palpi subequal in length, shorter than third maxillary palpus, fifth maxillary palpus slightly thicker than fourth, which is nearly triangular ( Fig. 8E ). Pronotum nearly oval ( Fig. 8D ). Tegmina with veins distinct; wings with radial veins nearly distinct, CuA ending at CuP, ( Fig. 8 G–H). Front femur type B2 ( Fig. 8F ). Pulvilli absent, arolia present.

MALE ABDOMEN AND GENITALIA. Supra-anal plate with paraprocts almost identical, simple sheet-like ( Fig. 8I ). Subgenital plate fan-shaped, distinctly asymmetrical with posterior margin strongly produced

at middle; two styli long, left stylus skewed to hind margin of subgenital plate, distance between two styli very short ( Fig. 8J ). Phallomere complex, L1 small with slender and curved filamentary structure, L2v and L2vm broad, L2d dentate and sheet-like, L3 robust with apex of the uncinate part tapering; R1 arc-shaped, R2 irregular bone sheet and weakly sclerotized, R3 short simple sheet-like ( Fig. 8 K–M).
