Description (Female): Body of medium size, pubescent, body colour dark brown to yellowish brown (body colour depends on the specimens’ location); head dark brown in colour with six, short, longitudinal light coloured stripes on the occiput, head rounded with a distinct angularly curved clypeal suture, the apex of the angle reaches the level of lower edges of antennal sockets and about near the middle ocellus. Colour of maxillary and labial palpi almost similar, brown to yellowish brown, 1 st and 2 nd segments very small, length of 3 rd and 4 th segments almost equal and 5 th one slightly longer than the previous segments of maxillary palpi. Pronotum is wider than long and is dark to light brown in colour; tegmina reaches middle of abdomen or slightly short of abdominal end and the hind wings longer than tegmina. Abdomen, legs and cerci are of light brown colour, fore tibiae with large hole-like external and small internal tympanum. Hind femur significantly longer than hind tibiae and ovipositor, hind tibia armed with 7 external and 6 internal subapical spurs. Length of ovipositor, more or less equal to hind tibiae, apices not more pointed.

Measurements (mm) Female: Body length 16-17; head length 3.50, width 2.50, with eyes 4; pronotum 2.5- 2.75, width 4-4.25; tegmina 9-9.75; hind femur 8-8.50, hind tibia 5.50 and ovipositor 5.

Description (Male): Some additional characters for this species ( A. asiaticus ): The body length including different parts, tegmina and legs have been described. Morphological characters of examined specimens from West to Southern India are more or less similar, except for body colour and length; besides, conforming to earlier description of A. asiaticus . Pronotum significantly wider than long and also length of head; tegmina reaching 6 th to 7 th abdominal tergite or slightly short of abdominal end and hind wings are longer than tegmina or are caudate, in our specimens both types could be observed. Tegmina with 4 to 5 oblique veins, lateral side of tegmina with 6 equally spaced longitudinal veins, the mediastinal vein is 3-branched. Hind femur longer than hind tibiae, hind tibiae dorsally armed with 7 or 8 external and 6 or 7 internal subapical spurs.

Measurements (mm) Male: Body length 15-18; head length 3-3.25, width 2.75-3.25, with eyes 4-4.25; pronotum 2.40-2.50, width 4-4.50; tegmina 9-9.75; hind femur 8-8.50; hind tibia 5-5.50.

Remarks: In this paper, the female is described for the first time. Some morphological characters of males are also added with suitable photographs.

Distribution: Asia-tropical, Indian subcontinent, India (Rajasthan, Tamil Nadu and Maharashtra).
