SPILOCUMA WATLING, 1977

Type species: Spilocuma salomani Watling, 1977

Body: Carapace shorter than abdomen and similar in length to peraeon; abdomen shorter or same size as carapace and peraeon together.

Cephalothorax: From dorsal view the carapace appears laterally compressed anteriorly. Pseudorostral lappets extend beyond frontal lobe and meet in midline. Antennal notch as a subacute or acute incision. Anterolateral corner with acute tooth. Frontal lobe from 1/5 or less to 1/4 of the carapace length; as wide as long; somewhat extended; with ocular pigment and with eye lenses.

Antenna 1 with basal article of the peduncle straight; shorter than the other two articles together. Main flagellum bi-articulated; with two aesthetascs in distal-most article; may have two aesthetascs on proximal article. Accessory flagellum uni-articulated; may have a brush of setae. Males with antenna 2 not reaching the end of the peraeon; anterior margin with padlike sensory setae; without sensory setae on anterior margin of article four. Antenna 2 in females with four articles.

Maxilliped 3 basis arcuate; not projected over ischium. Ischium shorter than merus. Merus extended dorso-distally over carpus or merus slightly expanded laterally. Carpus equal to or shorter than propodus and dactylus together.

Peraeon: Peraeonite 2 narrow; with ventrolateral expansion; overriding peraeonite 3 or overriding peraeonite 1 and peraeonite 3. Peraeonite 3 may have ventrolateral expansion extended backwards overriding peraeonite 4. Peraeonite 4 may have ventrolateral expansion overriding peraeonite 5.

Females and males with fully developed exopods on peraeopods 1–3 and reduced on peraeopod 4. Peraeopod 1 with basis arcuate, with row of setae; may have row of setae on the carpus; carpus longer than propodus. Peraeopod 2 with ischium; dactylus longer than propodus. Peraeopod 4 with ischium.

Pleon: Pleonite 6 shorter than peduncle of uropods. Pleonite 6 slightly extended past the insertion of the uropods.

Uropod endopod bi-articulated; proximal article longer than distal one. Uropod exopod with proximal article shorter than distal one. Peduncle of uropods slightly longer than rami; rami approximately same length. Males without pleopods.
