EOCUMA MARCUSEN, 1894

Synonymy: Mossambicuma Day, 1978 .

Type species: Eocuma hilgendorfi Marcusen, 1894

Body: Carapace shorter than abdomen and longer than peraeon; abdomen longer than carapace and peraeon together.

Cephalothorax: From dorsal view the carapace may appear laterally compressed anteriorly or posteriorly; may be oviform posteriorly. Carapace may have middorsal ridge, dorso-lateral ridges, lateral ridges and/or lateral horns. Pseudorostral lappets extend beyond frontal lobe; meet in midline or extend towards midline but do not meet (or partially meet leaving a suture between them). Antennal notch not distinct, as a depression or as a subacute or acute incision. Anterolateral corner bluntly rounded, with subacute or acute tooth. Branchial siphons extend just beyond pseudorostrum or more rarely are long, extending much beyond the pseudorostrum. Frontal lobe from 1/5 or less to more than half of the carapace length; variable in length with respect to width; anteriorly linguiform, may be somewhat extended; may have ocular pigment and/or eye lenses.

Antenna 1 with basal article of the peduncle arcuate or straight; as long as or shorter than the other two articles together. Main flagellum uni-, bi- or triarticulated; with second and third article approximately same length; one, two, three or more aesthetascs in distal-most article; may have two aesthetascs on proximal article. Accessory flagellum reduced or absent; uni-articulated; may have a brush of setae; with or without aesthetasc. Antenna 2 in males reaching half length or end of the pleon; with sensory setae on anterior margin of article four. Antenna 2 in females with one or two articles.

Maxilliped 3 basis geniculate, arcuate or straight; extended dorso-distally over ischium beyond the articulation of the ischium and merus. Ischium variable length with respect to merus. Merus extended dorsodistally over carpus. Carpus may be distally widened; equal to or shorter than propodus and dactylus together. Propodus oviform, may be distally widened; with or without brush of setae.

Peraeon: First peraeonite well exposed, visible only above lateral midline or not visible. Peraeonite 2 variable width with respect to other peraeonites; may have ventrolateral expansion overriding peraeonite 3, carapace and peraeonite 3 or not overriding other somites. Peraeonite 3 without ventrolateral expansion or extended backwards overriding peraeonite 4. Peraeonite 4 without ventrolateral expansion or with ventrolateral expansion overriding peraeonite 3 or 5.

Peraeopod 1 with basis arcuate or straight; may have row of setae; with dorso-distal projection on the basis totally or partially covering the ischium; inner apical angle may be extended to form a subtriangular tooth-like process or a convex process; may have row of setae on the carpus; carpus variable length with respect to basis; with or without a brush (3 or more) of long setae on the propodus (setae longer than carpus) or setae in a linear arrangement along propodus; basis longer than or equal to propodus; carpus longer or equal than propodus; dactylus with or without three terminal setae. Peraeopod 2 without ischium; dactylus longer than propodus. Peraeopod 4 with ischium.

Pleon: Articular pegs may be present. Pleonite 6 longer than wide; longer than peduncle of uropod. Whole width of terminal end of pleonite 6 may be extended between uropods; ending in a point, a line or a rounded apex. A narrow or wide portion of the terminal end of pleonite 6 may be extended between uropods; ending in a line or a rounded apex. Anal plates may extend posteriorly beyond distal margin of pleonite six.

Uropod endopod uni-articulated. Uropod exopod with proximal article shorter than distal one. Rami longer than peduncle; rami approximately same length. Rami with or without terminal setae. Males with five pairs of pleopods. When present, the process of the endopod of the pleopod is well developed or reduced.
