Diagn. Caput quam segmenta duo priora perrei brevius. Processus tibialis pedum percei primi paris 

 basin processus carpalis attiugens vel superans; margo anterior processus carpalis serratus, 

 margine posteriore metacarpi longior. Carpus pedum tertii ac quarti parium valde dilatatus, 

 margine posteriore convexo. Pedes trium parium ultimorum pedibus tertii ac quarti parium 

 multo longiores; femur dilatatum; metacarpus valde elongatus, metacarpo pedum tertii ac 

 quarti parium multo longior. Latera segmentorum plei rotundata. Pedes uri primi paris 

 apicem pedum ultimi paris longe non attingentes; ramus externus interno brevior. Ramus 

 internus ultimi paris latitudinem pedunculi longitudine superans. Telson tertiam partem 

 longitudinis pedunculi pedum uri ultimi paris aequans. 



The head is shorter than the first two pergonal segments. The tibial process of the first 

 pair of perwopoda reaches to the base of the carpal process or farther; the front margin 

 of the carpal process is serrated, longer than the hind margin of the metacarpus. The 

 carpus of the third and fourth pairs is very dilated, the hind margin convex. The last 

 three pairs are much longer than the next preceding two pairs; the femur is dilated; the 

 metacarpus is very elongated, much longer than the metacarpus of the third and fourth 

 pairs. The lateral parts of the yleonal segments are rounded. The first pair of uropoda 

 are far from reaching to the apex of the last pair; the outer ramus is shorter than the 

 inner. The inner ramus of the last pair is longer than the breadth of the peduncle. The 

 telsov equals a third of the length of the peduncle of the last pair of uropoda.
