UPSELASPIS JONES, 1955

Type species: Upselaspis caparti ( Fage, 1951)

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

Cephalothorax: From dorsal view the carapace appears not to be laterally compressed. Pseudorostral lappets extend beyond frontal lobe and meet in midline. Antennal notch not distinct, as a depression or as a subacute incision. Anterolateral corner bluntly rounded or with subacute tooth. Frontal lobe 1/4 to half of the total carapace length; as wide as long; somewhat extended; without ocular pigment or eye lenses.

Antenna 1 with basal article of the peduncle arcuate; shorter than the other two articles together. Main flagellum bi-articulated; with two aesthetascs in distal-most article. Accessory flagellum uni-articulated; with brush of setae. Antenna 2 in males reaching end of pleon.

Maxilliped 3 basis geniculate or arcuate; extended dorso-distally over ischium beyond the articulation of the ischium and merus. Ischium as long as or shorter than merus. Merus extended dorso-distally over carpus. Carpus equal to or shorter than propodus and dactylus together.

Peraeon: First peraeonite not visible. Peraeonite 2 may have ventrolateral expansion; when present, it overrides peraeonite 3. Peraeonite 4 with ventrolateral expansion overriding peraeonite 5.

Peraeopod 1 with basis arcuate, with row of setae; carpus same size as propodus. Peraeopod 2 without ischium; dactylus longer than propodus.

Pleon: Pleonite 6 as long as wide; shorter than peduncle of uropod. Wide portion of distal end of pleonite 6 well extended between the bases of the uropods; ending somewhat concave. Anal plates may extend posteriorly beyond distal margin of pleonite 6.

Uropod endopod bi-articulated; two articles approximately same length. Uropod exopod with proximal article shorter than distal one. Peduncle slightly shorter than exopods of rami (equal length to endopod); endopod longer than exopod. Males with five pairs of pleopods.
