DESCRIPTION

Carapace

Subcylindrical carapace, cephalic region with four longitudinal spiny carinae: parallel orbital, gastro-orbital, supra-antennal, and antennal carinae; orbital carina distanced from the others, and only marked by small aligned spines; gastro-orbital, supra-antennal, and antennal carinae strongly raised; antennal carina more raised than the others; carapace groove pattern similar to that observed in Glyphea ; all regions of carapace with spiny tubercles uniformly arranged, decreasing in size ventrally in the branchial region.

Thoracic appendages

Poorly preserved Mxp3 (flattened and pointed dactylus); poorly preserved P1 (merus laterally flattened, with spiny dorsal and ventral margins) and P2 (merus laterally flattened, with spiny dorsal and ventral margins).

DISCUSSION

Charbonnier et al. (2013) provided a detailed description of the species. The configuration of the cephalothoracic grooves, the four cephalic carinae, and the tuberculated ornamentation of the specimens from Ste-Scolasse correspond to diagnostic characters of Glyphea muensteri . The sample is too small to produce a more detailed discussion.
