Haptocallisoma gen. nov. Scopelocheirus .— Oldevig 1959: 16.— Barnard & Karaman 1991: 528 (in part, part Scopelocheirus ) Paracallisoma.— Hendrycks & Conlan 2003: 2322.— Kilgallen & Lowry 2015: 20 (in part, part Paracallisoma ) Type species. Scopelocheirus abyssi Oldevig, 1959. Diagnosis. Mandible, incisor ordinary; left lacinia mobilis present, a stemmed, distally asymmetrically expanded, non-serrate blade; left and right setal row each with three robust setae, molar simple, conical, acute; palp attached level with molar. Lower lip, lobes widely separated. Maxilla 1, inner plate strongly setose medially; outer plate with eleven robust setae, in simple 7 / 4 arrangement; palp two-articulate, article 2 large, expanded distally . Maxilla 2, inner plate with oblique row of mediofacial pappose setae. Maxilliped well developed, inner plate emarginate distally, palp four-articulate. Coxae 1 and 2 large, broad, subrectangular. Gnathopod 1 simple, propodus longer than carpus, dactylus shrouded in setae. Gnathopod 2 subchelate, propodus shorter than carpus. Pereopods 3 to 7 prehensile (on P 7 poorly developed). Pereopods 3 and 4 carpus longer than wide. Pereopod 5, basis suboval. Uropod 1 peduncle normal, rami variable. Telson with apices incised. Etymology. From the Greek, hapto —to join, fasten to, lay hold of or grasp; in reference to the prehensile pereopods 3–7 of the species in this genus added to the common stem of the subfamily ‘- callisoma ’. Remarks. This new genus is characterized by the prehensile pereopods 3 to 7, the suboval basis of pereopod 5, and the large distally expanded article 2 of maxilla 1. Included species.
