Material examined. Syntypes of Lumbrineris salazari, Mexico, off Tuxpan, Veracruz, 2031.5’ N 96 º58.1’ W. 39 m (ECOSUR0027); USA, off Florida, 26 º 16 ’ 43 ” N83 º 12 ’ 49 ” W, R/V Sofla, station 8 c, 48 m (USNM75353); USA, off Florida, 25 º 16 ’ 54 ” N83 º 43 ’ 11 ” W, R/V Sofla, station 24 f, 88 m (USNM75355).
Description. Syntype (ECOSUR) complete with 69 chaetigers, L 10 =1.3 mm, A 10 =0.5 mm. Prostomium conical, as long as wide, with pair of nuchal organs, ventrally with buccal lips. Peristomium shorter than prostomium, anterior ring 3 / 4 of total peristomial length. All parapodia well developed, first four smaller than following. Prechaetal lobe in parapodia 1–33 inconspicuous, rounded; from parapodium 34 digitiform, increasing gradually but smaller than postchaetal lobe, from parapodium 43 until the end longer than postchaetal lobe. Postchaetal lobe in parapodia 1–35 short, conical, slightly longer than prechaetal lobe, from parapodium 36 increasing gradually but from parapodium 43 smaller than prechaetal lobe (Figures 6 F–G). All parapodia with small notopodia, with several notoaciculae. Composite multidentate hooded hooks in chaetigers 1–10, with short blade, with up to 5 teeth of similar size (Figure 6 H); simple multidentate hooded hooks from chaetiger 11, with up to 6 teeth, proximal tooth largest, with short hood (Figure 6 I); dorsal limbate chaetae in chaetigers 1–28, ventral limbate chaetae in chaetigers 1–13. Aciculae yellow, aristate, up to three in anterior parapodia and one in posterior. Pygidium with a pair of long and slender dorsal anal cirri, and a pair of short ventral anal cirri. Mandible fused for about 1 / 3 its total length. Maxillary apparatus with five pairs of maxillae (Figure 6 J); maxillary carriers as long as MI, joined to base of MI. MI forceps-like, with attachment lamella. MII shorter than MI, with four teeth, with ligament, with wide attachment lamella along 2 / 3 of posterior lateral edge. With broad strongly sclerotized connecting plate between MI and MII. MIII bidentate, distal tooth longest, with wide attachment lamella along entire posterior lateral edge. MIV with two teeth, proximal tooth tiny, wide attachment lamella along entire lateral edge. MV displaced lateral to MIV and MIII, reduced to attachment lamella.
Distribution. Gulf of Mexico. Lumbriconereis (= Lumbrineris) maxillosa Ehlers, 1918, from Aru Island (Pacific Ocean), could belong to Hilbigneris. The maxillary apparatus was illustrated with MII shorter than MI, and with a broad connecting plate between them, and described with composite and simple multidentate hooded hooks. The type material or additional materials are not available to corroborate this.
