“Carocryptus laticephalus n. sp.
Figs. 29A-29L
Description. 2.4 mm long. Cuticle striated, but not strongly so. Cephalon very broad with rounded posterolateral corners. Antenna 1 with single large tuft and two small apical segments and with no teeth present. Antenna 2 extends to about peraeonal segment VI; flagellum with five subequal articles. Peduncular segment 2 (basal segment) large and broad. All coxal extensions with acute posterolateral corners; no teeth present. Peraeopods I and II bulbous and prehensile with III somewhat so. Dactyli on peraeopods I, II, and perhaps III (it is broken) as long as or longer than propodi. Peraeopods IV–VII thin with elongate propodi; dactyli with short fringing setae on inner margin. All pleopods biramus; pleopod 1 with five long setae on endopod and four on exopod. Pleotelson small and enclosed in posterior extensions of pleopodal segment 5, with smooth lateral margins. Uropod with exopod about one-half length of endopod; each ramus tipped by single seta. The name of the species laticephalus, from the Greek, simply means broad head; the broadness of the head is a unique feature of the species described here.
Type locality. 11-912: 64°58'S, 114°13’W; 65°19'S, 114°06'W; 3312 m. Holotype.
Distribution and size. Known only from type locality.
Affinities. The broad cephalon and configurations of peraeopods I and II are unique. Other structures, such as the single seta on each uropodal ramus, are characteristics shared only by a few cryptoniscid species. Although there are only five flagellar articles on antenna 2, the last two peduncular articles are thin and resemble flagellar articles."
