GARCIA-MADRIGAL, María del Socorro. Cangrejos braquiuros (Brachyura) de la bahía de Maruata, Michoacán, México. Rev. biol. trop [online]. 2000, vol.48, n.1, pp.181-191. ISSN 0034-7744.

A total of 287 specimen of brachyuran crabs were collected in 1990-1991. The specimens belong to 42 species, 34 genera and 14 families. All species represent new records for the coast of Michoacan and include two range extensions: Micropanope cristimanus from Manzanillo to Maruata, and Glyptograpsus impressus from Acapulco to Maruata. The presence of Eupleurodon peruvianus, Epialtus sulcirostris and Mithrax spinipes represents a gap in their distribution. The families with haighest numbers of species were the Mithracidae (7) and Grapsidae (6). The species were sorted out in four groups acording to their zoogeographic affinity: Indopacific (4.76%), Amphiamerican (9.52%), Eastern Pacific (78.57%) and Mexican Pacific (7.14%).
