ZENOCUMA HALE, 1944

Type species: Zenocuma rugosum Hale, 1944

Body: Carapace shorter than abdomen and similar in length to peraeon; abdomen approximately as long as carapace and peraeon together.

Cephalothorax: From dorsal view the carapace appears not to be laterally compressed. Carapace with mid-dorsal ridge and with anterior transverse ridge. Pseudorostral lappets extend beyond frontal lobe and towards midline but do not meet (or partially meet leaving a suture between them). Antennal notch as an acute incision. Anterolateral corner bluntly rounded. Frontal lobe half of carapace length; as wide as long; anteriorly linguiform; with ocular pigment and eye lenses.

Antenna 1 with basal article of the peduncle arcuate; as long as the other two articles together. Main flagellum bi-articulated. Accessory flagellum uniarticulated; with brush of setae.

Maxilliped 3 basis arcuate; expanded (opercular); ventrally projected over ischium. Ischium shorter than merus. Carpus proximally widened; equal to or shorter than propodus and dactylus together. Propodus distally widened or oviform; with a brush of setae.

Peraeon: First peraeonite visible only above lateral midline. Peraeonite 2 with ventrolateral expansion; overriding peraeonite 1 and/or carapace and peraeonite 3. Peraeonite 3 extended backwards overriding peraeonite 4. Peraeonite 4 with ventrolateral expansion overriding peraeonite 5.

Females with fully developed exopods on peraeopods 1–3 and reduced on peraeopod 4. Peraeopod 1, opercular (with basis-carpus expanded, ischium and merus rotated to parallel positions); basis arcuate; ischium modified as a rounded lobe with exterior concavity; carpus oviform in shape with row of setae; brush (three or more) of long setae on the propodus (setae longer than carpus); carpus shorter than propodus. Peraeopod 2 with ischium; dactylus longer than propodus. Peraeopod 4 with ischium.

Pleon: Pleonite 6 as long as wide; shorter than peduncle of uropod. Pleonite 6 not extended past the insertion of the uropods. Anal plates extend posteriorly beyond distal margin of pleonite 6.

Uropod endopod bi-articulated; proximal article longer than distal one. Uropod exopod with proximal article shorter than distal one. Peduncle shorter than rami; endopod longer than exopod.
