Abstract

Dasybranchetus pacifica, collected in Concepcion Bay, Baja California Sur, Gulf of California, is described as a new species. In addition, the type species of the genus, Dasybranchetus fauveli Monro, 1931, is redescribed based on type material. The new species differs from D. fauveli in the absence of branchiae, the begining of the mid-dorsal lobe from chaetiger 2 instead of chaetiger 9, abdominal segments with well-developed neuropodial lobes, and hooded hooks with a main fang and three rows of subapical teeth in the following arrangement: 4 teeth in the basal line, 3 in the middle line, and 2 in the apical line.
