Nalocryptus longicaudatus Schultz 1977

“Nalocryptus longicaudatus n. sp.
Figs. 30A-30N

Description. 1.8 mm long. Cephalon broadly rounded with pointed posterolateral extensions extending beyond posterior margin of peraeonal segment I. Antenna 1 with single large tuft of setae. Coxal extensions with seven teeth on posterior margins. Propodi of peraeopods I–III bulbous; dactyli of peraeopods IV–VII thin with dactyli shorter than propodi. Propodi of peraeopods I–III each with two scalelike setae on inner margins. Pleopods biramus; pleopod 1 with five long setae on endopod, and four long and one short on exopod. Pleotelson elongate and set with­in elongated posterolateral margins of pleonal seg­ment 5. Ten serrate teeth on produced posterior margin of pleotelson. Uropods elongate with ex­opod about two-thirds as long as endopod, each with two long apical setae. The species name longicaudatus, from the Latin, refers to the elon­gate, taillike pleotelson.

Type locality. 11-943: 69°18'S, 94°50'W; 69°06'S, 95°02'W; 888 m. Holotype.

Distribution and size. 11-941 (1.7 mm); 11-943 (1.8 mm).

Affinities. Peraeopods I–III are bulbous (three bulbous peraeopods of the same type are also found on Cryptocotitus acus n. g., n. sp., described later). The species is also somewhat like Cumoechus insignis Hansen, 1916, which has bulbous peraeopods I–III. The cephalon is very wide in this specimen when compared with the width of the cephalon of C. insignis Hansen, however.”
