Paratype: New Caledonia, 22°52’42”S, 167°11’90”E, 400 m, rocky bottom with sponges, 12. V.1995, leg. A. A. Myers, non ovigerous, pocl 2.60 mm (OUMNH 2004-01-0001). ETYMOLOGY. — From the Latin praecipuus, meaning peculiar. In reference to the frontal region of the carapace, exhibiting a non-tridentate structure.

No host association is recorded for the paratype specimen, but this latter sample also contained examples of Spongicola levigata Hayashi & Ogawa, 1987 and Periclimenes forcipulatus Bruce,1991, both known hexactinellid sponge associates. DESCRIPTION Carapace smooth, lacking setae (Fig. 1 A-C, E, F). Anterior margin trilobed; rostrum poorly developed, tip upturned, adrostral furrows shallow, falling short of eyes.

Eyes not visible in dorsal or lateral view, anteriorly exposed. Antennular peduncle (Fig. 2D) short, second and third segments subequal in length, approximately half length of first segment; stylocerite well developed, slightly overreaching first segment, narrowing distally to a blunt point, ventral carina of first article poorly developed, statocyst well developed. External flagellum biramous, outer branch consisting of single segment (Figs 2D; 3A), longer free ramus approximately 0.4 times carapace length. Mesial flagellum slender, filiform, approximately 0.7 times carapace length. Carpocerite of antenna (Fig. 1A, B, E, F) falling short of antennular peduncle; basicerite with well developed ventral tooth; scaphocerite (Fig. ...
