CORICUMA WATLING & BREEDY, 1988

Type species: Coricuma nicoyensis Watling & Breedy, 1988

Body: Carapace shorter than abdomen and peraeon; abdomen approximately as long as carapace and peraeon together.

Cephalothorax: From dorsal view the carapace appears laterally compressed anteriorly. Carapace with mid-dorsal serration. Pseudorostral lappets do not extend beyond the frontal lobe. Antennal notch as a subacute incision. Anterolateral corner with subacute tooth. Frontal lobe half of carapace length; longer than wide; anteriorly linguiform; without eye lenses.

Antenna 1 with basal article of the peduncle straight; shorter than the other two articles together. Main flagellum tri-articulated; with second article longer than third; with one aesthetasc in distal-most article. Accessory flagellum uni-articulated. Antenna 2 in males not reaching the end of the peraeon; posterior margin modified for grasping. Antenna 2 in females with one article.

Maxilliped 3 basis arcuate; extended dorso-distally over ischium beyond the articulation of the ischium and merus. Ischium shorter than merus. Merus slightly expanded laterally; equal to or shorter than propodus and dactylus together.

Peraeon: Peraeonite 2 wide or proportional to other peraeonites.

Peraeopod 1 with basis arcuate; with inner apical angle extended to form a convex process; carpus longer than propodus. Peraeopod 2, dactylus longer than propodus. Peraeopods 2–5, ischium absent.

Pleon: Pleonite 6 as long as wide; shorter than peduncle of uropod. Pleonite 6 slightly extended between the bases of the uropods.

Uropod endopod bi-articulated; proximal article shorter than distal one. Uropod exopod with proximal article shorter than distal one. Peduncle approximately as long as rami; exopod longer than endopod. Males with two pairs of pleopods. Pleopodal endopod without process.
