| Summary: | Platycuma bamberconfabulor sp. nov. (FigS 1 & 2) Material examined. Holotype - subadult male (NIWA 80709) Ross Sea, Antarctica, RV Tangaroa cruise TAN 0 802, Station 88, 76.6097 °S, 176.7560 °E, 360 m, 17 February 2008. Diagnosis. Carapace laterally expanded and somewhat dorsoventrally flattened, anterior margin excavate in dorsal view, dorsal margin sinuous in lateral view, uropod peduncles less than twice length of pleonite 6. Etymology. The species is named bamberconfabulor for Roger N. Bamber in combination with confabulor, from the Latin meaning debate, argue, or discuss in honor of Roger’s fondness for discussion of crustacean terminology. Description. Subadult male holotype. Body (Figs 1 A, 1 B) white. Carapace nearly circular when viewed from above, slightly wider posteriorly, anterior margin excavate; overlapping pereonites 1 and 2; highest about midway along length, with shallow paired posterior swellings extending ventrally to lateral lamellar margin; pseudorostral lobes extending in front of obsolete eyelobe; antennal notch broad, anteroventral corner without teeth; lateral lamellar margin extends from anteroventral corner to posterior margin. Pleon about half body length; pereonites 4 and 5 and pleonites 1 through 4 with paired dorsolateral keels; pleonite 4 and 5 subequal. Antennule (Fig. 1 C) not geniculate; basal article of peduncle slightly shorter than articles 2 and 3 combined, with terminal seta; accessory flagellum minute, of two articles; main flagellum of three articles, distal two articles with one aesthetasc each. Antenna not illustrated, immature, without annulations or setae, but extending past posterior border of carapace, suggesting the individual is one molt from adult, and would be expected to have a medium to long antennal flagellum as an adult. Mouth parts: Mandibles and maxillae not illustrated, not dissected in order to preserve integrity of carapace. Maxilliped 1 (Fig. 1 D) basis wide, dorsomedial ridge armed with four plumose setae, endite simple, with single terminal ... |
