Neotype (NHM 930.0.8.258290) with body smooth, clean, white, leathery. From segments 6, body with minute papillae dense on segments 7 and 8, but evenly spaced in other segments. Welldefined clusters of cuticular papillae in single row starting on segment 8, encircling every single segment to posterior end, includKelly Sendall Sergio I. SalazarVallejo ZooKeys 286: four (203)ing final segments opposite ventrocaudal shield. Physique as much as 20 mm long, 7 mm wide, about 28 segments. Prostomium oval, hemispherical, opalescent, translucent (Fig. 6A). Peristomium rounded, raised at the position of mouth and with papillae sparsely covering the majority of surface. Mouth circular, fully covered by minute papillae, situated halfway involving prostomium and anterior border of second segment. Initial 3 chaetigers with 50 slender, bronze, slightly falcate hooks inside a closely apposed group; hooks without the need of dark locations. A single pair of slender translucent genital papillae in intersegmental groove involving segments 7 and 8. Preshield area with 7 segments, with brief couplets of fine capillary chaetae protruding from body wall. Ventrocaudal shield ribs poorly developed, concentric lines not visible; suture indistinct. Anterior margins angular; anterior depression deep; anterior keels not exposed (Fig. 6B). Lateral margins rounded, expanded medially, decreased posteriorly. Fan barely reaching posterior shield corners, medially projected, denticulated. Marginal chaetal fascicles incorporate nine lateral ones, chaetae in oval arrangement, and five posterior fascicles, chaetae in a slightly curved arrangement and with each fascicle parallel to subsequent. Peg chaetae long, emerge from an extended fleshy cone; a small fascicle of delicate capillary chaetae emerge from the base in the fleshy cone bearing peg chaetae. Branchiae mainly eroded, placed on oval, wide branchial plates (Fig. 6C). Variation. The ventrocaudal shield is medially fused; its fan is slightly projected beyond the posterior margin and its margins are denticulated (Fig. 6D ). The posterior corners are rounded and by no means prominent or reaching the fan posterior margin level. Bigger specimens could have.
