Antennal acicles serrate and fused to second peduncular segment. The brush of setae is present on upper margins of both chelae. Upper outer surface of palm of left chela with pronounced stitch mark or oblique laminar tubercles, usually six or seven in numbers, forming what has been called a stridulatory mechanism. The middle of the inner surface of the palm of the left chela has a strong longitudinal ridge below brush of setae. The mesial plane of the merus of the right cheliped is without tuft of setae. Lateral surfaces of propodi and dactyli of left third pereopod flattened and separated from dorsal surface by distinct ridge or crest; ventromesial surfaces of dactyls of left second and third pereopod with longitudinal ridge of closely-set tubercles Ambulatory legs covered with long setae.
