Material examined: 12 specimens (CNAP–ICML PO-37-103): 1 specimen, Caleta E1B2, 16°49.797’N, 99°54.062’W, May 25 2006, 12 m, coarse sand. 2 specimens, Palmitas E2B1, 16°42.420’N, 99°54.733’W, May 25 2006, 10.5 m, coarse sand. 3 specimens, Palmitas E2B2, 16°42.420’N, 99°54.733’W, May 25 2006, 10.5 m, coarse sand. 4 specimens, Jardín E3B1, 16°49.436’N, 99°54.981’W, May 26 2006, 12 m, coarse sand. 2 specimens, Jardín E3B2, 16°49.436’N, 99°54.981’W, May 26 2006, 12 m, coarse sand.
Comparative material examined. Erinaceusyllis cryptica, 3 specimens (MNCN 16.01 /11457) Spain: Cala Mal Paso Cuevas da Almanzora, Almería, Mediterranean Sea. Sphaerosyllis bilobata, 6 specimens (MNCN 16.01 / 6152) Cuba: Punta del Francés, Isla de Pinos, Canarreos Archipelago, Caribbean Sea, 1 m.
Remarks. Erynaceusyllis bidentata is characterized by having compound bidentate chaetae with long blades, the median antenna inserted in anterior position and bidentate aciculae. Similar compound bidentate chaetae are present in Erinaceusyllis bilobata (Perkins 1981) and in Erinaceusyllis cryptica (Ben-Eliahu 1977); however, these species do not have the subdistal enlargement observed in the chaetae of E. bidentata, and both have acuminate and unidentate aciculae and the median antenna inserted in the posterior part of the prostomium. The specimens herein examined agree well with the original description of E. bidentata. Only a small difference was observed in the simple chaetae since they appear to be bidentate although they were originally described as unidentate. However, since the subdistal tooth is very small and difficult to detect, this character was not considered taxonomically important enough to make a difference for its taxonomic identification.
Habitat. Shallow depth, medium to coarse sand, mixed bottoms (sand, algae, detritus, dead coral).
Distribution. Eastern Africa (Mozambique), Western Australia and Southern Mexican Pacific (Acapulco Bay).
