Type species: Speleocuma guanche Corbera, 2002

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

Cephalothorax: In dorsal view the carapace appears laterally compressed anteriorly. Carapace with middorsal serration. Pseudorostral lappets may extend beyond frontal lobe and meet in the midline. Antennal notch as a depression. Anterolateral corner bluntly rounded or with subacute tooth. Frontal lobe 1/3 of the total carapace length; anteriorly linguiform; with ocular pigment and with eye lenses.

Antenna 1 with basal article of the peduncle arcuate; shorter than the other two articles together. Main flagellum bi-articulated; with one or two aesthetascs in distal-most article. Accessory flagellum uni-articulated. Males with antenna 2 not reaching the end of the peraeon.

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

Peraeon: Peraeonite 2 with ventrolateral expansion overriding peraeonite 1 and/or carapace or peraeonite 1 and/or carapace and peraeonite 3. Peraeonite 3 extended forward overriding peraeonite 2 or backwards overriding peraeonite 4. Peraeonite 4 with ventrolateral expansion overriding peraeonite 5.

Females and males with fully developed exopods on peraeopods 1–3. Peraeopod 1 with basis arcuate. Peraeopod 2 with ischium; dactylus longer than propodus. Peraeopod 4 with ischium.

Pleon: Pleonite 6 longer than wide; shorter than peduncle of uropod. Wide portion of the distal end of pleonite 6 slightly extended past the insertion of the uropods; apex rounded. Anal plates extend posteriorly beyond distal margin of pleonite 6 and bear setae on posterior margin.

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