GLYPHOCUMA HALE, 1944

Type species: Glyphocuma bakeri Hale, 1936

Body: Carapace shorter than abdomen and similar in length or longer than peraeon; abdomen longer than carapace and peraeon together.

Cephalothorax: From dorsal view the carapace appears laterally compressed anteriorly. Carapace with mid-dorsal ridge or mid-dorsal serration; may have dorso-lateral ridges. Pseudorostral lappets do not extend beyond the frontal lobe. Antennal notch as a depression or as a subacute incision. Anterolateral corner bluntly rounded or with subacute tooth. Frontal lobe from 1/4 to half of the total carapace length; longer than wide; anteriorly linguiform; with or without ocular pigment and eye lenses.

Antenna 1 with basal article of the peduncle geniculate or arcuate; shorter than the other two articles together. Main flagellum bi- or tri-articulated; with second article longer than third; may have two or three aesthetascs in distal-most article and/or a group of aesthetascs on proximal article. Accessory flagellum bi-articulated; may have a brush of setae. Antenna 2 in females with three articles.

Maxilliped 3 basis arcuate or straight; extended dorso-distally over ischium beyond the articulation of the ischium and merus. Ischium longer than or as long as merus. Carpus equal to or shorter than propodus and dactylus together. Propodus may be oviform; may have a brush of setae.

Peraeon: First peraeonite well exposed or visible only above lateral midline. Peraeonite 2 wide or proportional to other peraeonites; 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 or overriding peraeonites 3 and 5.

Females and males with fully developed exopods on peraeopods 1–3. Males also have a fully developed or reduced exopod on peraeopod 4. Peraeopod 1 with basis arcuate, with row of setae; may have a brush (three or more) of long setae on the propodus (setae longer than carpus) or setae in a linear arrangement; carpus equal to or shorter than propodus. Peraeopod 2 with or without ischium; dactylus longer than propodus. Peraeopod 4 with ischium.

Pleon: Pleonite 6 longer than wide; shorter than peduncle of uropod. Whole width of terminal end of pleonite 6 well extended past the insertion of the uropods; terminally concave (with two projections) or apex rounded. Anal plates may extend posteriorly beyond distal margin of pleonite 6.

Uropod endopod bi-articulated; articles variable in length with respect to each other. Uropod exopod with proximal article shorter than distal one. Peduncle of uropods longer or same size as rami; rami approximately same length or exopod longer than endopod. Males with five pairs of pleopods.
