Lamispina chilensis n. sp. Figure 18 Therochaetella chilensis Hartman, 1967:128–129 (partim). Type material. Southeastern Pacific Ocean. Holotype (USNM 56470) and one paratype (USNM 1251914), off Santiago, Chile, RV Eltanin Antarctic Expedition, cruise 26, Sta. 752 (33°14' S, 71°47' W), 209 m, 26 Sep. 1963 (paratype anterior fragment 7 mm long, 1 mm wide, cephalic cage 3 mm long, 21 chaetigers). Paratype (USNM 1251915), off Santiago, Chile, RV Eltanin Antarctic Expedition, cruise 26, Sta. 753 (33°16' S, 71°47' W), 192 m, 26 Sep. 1963 (anterior fragment 5 mm long, 1 mm wide, cephalic cage 2.5 mm long, 18 chaetigers). Additional material. Southeastern Pacific Ocean. One specimen (LACM 6532), off Santiago, Chile, RV Eltanin Antarctic Expedition, cruise 26, Sta. 752 (33°14' S, 71°47' W), 209 m, 26 Sep. 1963 (7 mm long, 1.5 mm wide, cephalic cage 4 mm long, 23 chaetigers; gonopodial lobes on chaetiger 5). Description. Holotype (USNM 56470) an anterior fragment, cylindrical, anteriorly swollen, posteriorly reduced in diameter from chaetiger 11 (Fig. 18A); 7.5 mm long, 1 mm wide, cephalic cage 3.5 mm long, 23 chaetigers (constricted region starts at chaetiger 12). Body papillae long, capitate, arranged in single transverse series at chaetigers 1–3, then in two transverse series; dorsal papillae longer, parapodial papillae long, ventral papillae shorter (Fig. 18B). All with a thin crust of fine sediment particles. Cephalic hood exposed, short, margin papillated (Fig. 18A). Prostomium low cone, eyes not seen; caruncle short, triangular. Palp and branchial features observed in a non-type specimen (LACM 6532). Palps thick, slightly shorter than longest branchiae; palp keels low, rounded. Lateral lips well developed; ventral lip rounded, dorsal lip reduced. Branchiae cirriform, arranged as a single row with eight filaments, larger ones slightly longer than palps. Nephridial lobes not seen. Cephalic cage chaetae 3.5x longer than body width; chaetigers 1–3 forming cephalic cage. Chaetae arranged in short groups; chaetiger 1 ...
