Type material

Caribbean Sea: Beach Ana and Jose, deviation of Boca Paila, Quintana Roo (19 ° 549N, 87 ° 269W), coll. S.I. Salazar and J.R. Bastida, 11 February 2001, holotype (LACM-AHF-POLY 2191); paratype (ECOSUR-0082) .

Description

Holotype

Complete specimen with 44 segments, 5.6 mm long, 0.6 mm wide at chaetiger 6. Prostomium narrow, with slight apical indentation, two eyes present at level of palps. Caruncle extending posteriorly to end of chaetiger 4; occipital antenna absent ( Figure 1A View Figure 1 ). Palps extending posteriorly for 10–11 segments. Colour in alcohol pale yellow. Body and palp pigmentation absent.

Chaetiger 1 reduced, notopodial lamellae and notochaetae absent; with short neurochaetae. Winged capillary notochaetae of chaetigers 2–4, 6, and subsequent chaetigers in two rows, notochaetae of posterior row longer ( Figure 1B View Figure 1 ); middle and posterior chaetigers with fimbriated capillaries ( Figure 1C View Figure 1 ), without spines. Winged capillary neurochaetae of chaetigers 2–4, and 6 ( Figure 1D View Figure 1 ) in two rows, neurochaetae wider and shorter than notochaetae ( Figure 1B, D View Figure 1 ). Five bidentate hooded hooks begin on chaetiger 7, with up to seven hooks in a series from chaetiger 8, hooks without companion capillaries; each hook with wide angle between main fang and shaft and narrow angle between main fang and apical tooth, without constriction on shaft ( Figure 1E View Figure 1 ).

Chaetiger 5 greatly modified, larger than adjacent segments; notochaetae absent, four ventral winged capillaries. Major spines of two types in double row: (1) anterior row with four to five spines distally expanded into two very pronounced bluntly rounded knobs, enclosing a deep central concavity ( Figure 1F View Figure 1 ); (2) posterior row with four to five falcate spines ( Figure 1G View Figure 1 ).

Branchiae on chaetigers 2–4, 6–34 ( Figure 1A View Figure 1 ); longest from chaetigers 10–24.

Gizzard-like structure in intestinal tract absent.

Pygidium damaged, morphology cannot be determined.

Ovigerous female with ova in segments 8–21.

Variability

Incomplete paratype measured 7 mm long, 0.5 mm wide, with 61 segments. Palps extending posteriorly for 11 segments. Branchiae on chaetigers 2–4, 6–26, free from notopodial postchaetal lamellae and branchiae longest on chaetigers 10–19. All anterior and middle notochaetae with bristles (fimbriated). Hooded hooks from chaetiger 7, with up to six hooks per fascicle, not accompanied by capillaries. Some major spines of anterior row without deep central concavity ( Figure 1F View Figure 1 ); posterior row with four to five falcate spines ( Figure 1G View Figure 1 ). Ovigerous female with ova in segments 10–61.

Remarks

Boccardia salazari sp. nov. is closely related to Boccardia tricuspa ( Hartman, 1939) in lacking notochaetae on chaetiger 1, posterior notopodial spines, occipital antenna, and without pinicillate spines. Boccardia salazari differs from B. tricuspa in having prostomium incised, major spines of chaetiger 5 with a distal concavity instead of prostomium rounded, and major spines of chaetiger 5 tridentate. Also, Boccardia salazari sp. nov. is closely related to Boccardia galapagense Blake, 1986 , in having incised prostomium and fimbriated capillaries, lacking occipital antenna, notopodial lamellae and notochaetae on chaetiger 1. Boccardia salazari differs from B. galapagense in having eyes, lacking pinicillate spines, and posterior spines, instead of eyes absent, penicillate - topped spines, and posterior spines present.
