PSEUDOLEPTOCUMA WATLING, 1977

Type species: Pseudoleptocuma minus ( Calman, 1912)

Body: Carapace shorter than abdomen and similar in length or shorter than peraeon; abdomen longer than 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 depression or as a subacute incision. Anterolateral corner with subacute tooth. Frontal lobe from 1/3 to half of carapace length; longer than wide; somewhat extended; may have ocular pigment.

Antenna 1 with main flagellum bi-articulated. Accessory flagellum uni-articulated. Males with antenna 2 reaching end of pleon. Antenna 2 in females with three articles.

Maxilliped 3 basis arcuate; slightly expanded laterally over ischium. Ischium shorter than merus. Merus slightly expanded laterally. Carpus oviform; 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 or peraeonite 1 and/or carapace and peraeonite 3. Peraeonite 3 extended backwards overriding peraeonite 4 or forward and backwards overriding peraeonites 2 and 4. Peraeonite 4 with ventrolateral expansion overriding peraeonite 5 or peraeonites 3 and 5.

Females and males with fully developed exopods on peraeopods 1–3. Females with reduced and males with fully developed exopods on peraeopod 4. Peraeopod 1 with basis arcuate, with row of setae; may have row of setae on the carpus; brush (three or more) of long setae on the propodus (setae longer than carpus) or setae in a linear arrangement; carpus equal in length to propodus. Peraeopod 2 with ischium; dactylus and propodus approximately same length. Peraeopod 4 with ischium.

Pleon: Pleonite 6 longer than wide; shorter than peduncle of uropod. Whole width of terminal end of pleonite 6 slightly extended between the bases of the uropods; apex rounded.

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 or exopod longer than endopod. Males with three pairs of pleopods. Pleopodal endopod with welldeveloped process.
