Cephalothorax : From dorsal view the carapace appears not to be laterally compressed. Carapace may have mid-dorsal, dorso-lateral, lateral and posterior transverse ridges, as well as mid-dorsal serration. Pseudorostral lappets extend beyond frontal lobe and meet in midline. Antennal notch as a depression, subacute or acute incision. Anterolateral corner bluntly rounded or with subacute tooth. Branchial siphons long, extending much beyond pseudorostrum or short, extending just beyond carapace. Frontal lobe 1/4 of carapace length; as wide as long; somewhat extended or anteriorly linguiform; without ocular pigment or eye lenses. Antenna 1 with basal article of the peduncle arcuate or geniculated; longer than the other two articles together. Main flagellum bi-articulated; with two aes- thetascs in distal-most article. Accessory flagellum uni-articulated, may have a brush of three or more setae. Antenna 2 in males reaching end of pleon. Antenna 2 in females with three articles. Maxilliped 3 basis arcuate or straight; not projected over ischium. Ischium shorter or same length than merus. Merus slightly expanded laterally. Carpus variable in length with respect to propodus and dactylus together. Peraeon : Peraeonite 2 with ventrolateral expansion overriding peraeonite 1 and/or carapace and peraeonite 3, or only peraeopod 3. Peraeonite 3 may have ventrolateral expansion extended backwards overlapping peraeonite 4. Peraeonite 4 with ventrolateral expansion overriding peraeonite 5 or peraeonites 3 and 5. Females with fully developed exopods on peraeopods 1 and 2, and reduced or small exopod on peraeopod 3. Males with fully developed exopods on peraeopods 1– 4. Peraeopod 1 with basis arcuate; carpus with or without row of setae, longer than propodus; dactylus with or without terminal setae. Peraeopod 2 with ischium; dactylus longer than propodus. Peraeopod 4 with ischium. Pleon : Pleonite 6 as long as or longer than wide, shorter than peduncle of uropod, may have three setae on posterior edge. Wide portion of distal end of pleonite 6 slightly extended between the bases of the uropods and ending in a line or slight point. Anal plates may extend posteriorly beyond distal margin of pleonite six. Uropod endopod uni-articulated. Uropod exopod with proximal article shorter than distal one. Peduncle of uropods longer than rami; rami approximately same length or endopod slightly shorter. Males with five pairs of pleopods that do not bear a process. Species included : 1.
