Description
The Arostropsis male adult has an overall coloration which appears to be metallic green and that is caused by numerous small lanceolate scales coating the legs and sides of the body. The male has an elongated body which is 6.4 millimetres (0.25 in) in length, 1.3 millimetres (0.051 in) tall, and with an overall width of 1.8 millimetres (0.071 in). The rostrum is approximately one and a half times as long as it is wide and is noted for being narrower than the rest of the head. Only the left mandible is still present and attached to the head and the tip section has a distinct curve and the mandible as a whole has a knife like shape.[1] The legs are elongated and with the protibiae hosting a row of slender spines. The tip of the tibia, called the corbel, is open, lacking a second row of spines. Arostropsis is distinguished from the modern genera of Naupactini that have open corbels by the narrow rostrom and morphology of the antennae.[1]
