diagnosis

Diagnosis. Prostomium bluntly pointed anteriorly, with narrow, short caruncle extending to posterior margin of setiger 1; peristomium expanded laterally, partially enveloping prostomium and extending around base of palps. Two pairs of eyes present or eyes absent. Postsetal notopodial lamellae of setiger 1 large, spoonshaped, notopodial lamellae of setigers 1 – 13 with 2 – 8 digitiform extensions along margin, lamellae fused with base of branchiae. Notosetae of setiger 2 and succeeding setigers in three groups, including a group of capillary setae dorsal to an anterior row of stout capillaries, and a posterior row of thinner capillary setae. Neurosetae in three groups, two rows similar in morphology to notosetae, plus ventral fascicle of inferior sabre setae; unidentate neuropodial hooded hooks replacing anterior row of capillary neurosetae from setiger 19. Branchiae from setiger 1, smooth, partially fused with notopodial lamellae, distal end free. Accessory branchiae from setiger 19, initially with single digitate lobe, increasing to six digitate lobes in posterior setigers. Lateral organ between notopodial and neuropodial lamellae present from setiger 1. Pygidium reduced, with small papillae on ventral surface.

etymology

Etymology. The species epithet latilamella (derived from the Latin adjective latus for broad, wide and the Latin noun lamella for a small plate) refers to the large, spoon-shaped postsetal notopodial lamellae on setiger 1.
