Stomatopods (Crustacea: Hoplocarida) from the Gulf of Tehuantepec, Mexico
A total of 1173 specimens of Stomatopoda were captured in 27 localities at different depths (20 to 73 m) during three oceanographic cruises in the Mexican Pacific along the continental shelf of the states of Oaxaca and Chiapas. Seven species were identified of the families Eurysquillidae, Lysiosquil...

| Summary: | A total of 1173 specimens of Stomatopoda were captured in 27 localities at different depths (20 to 73 m) during three oceanographic cruises in the Mexican Pacific along the continental shelf of the states of Oaxaca and Chiapas. Seven species were identified of the families Eurysquillidae, Lysiosquillidae and Squillidae. Squilla hancocki and Squilla parva were the most abundant species and the most frequently found together. The relationships between total length and carapace length were obtained for these species, which show that males of S. hancocki have a longer carapace length than females having the same total length, whereas for S. parva the opposite occurs. Larger sizes than previously reported were obtained for Lysiosquilla panamica and Squilla mantoidea. Squilla bigelowi was recorded for the first time in the Gulf of Tehuantepec. All the species were found in the intermediate platform (25-60 m); E. veleronis, S. hancocki and S. parva extended their distributions to the external platform (60-120 m), and S. hancocki and S. parva reached the circalittoral zone (10-25 m).<br>Se capturaron un total de 1173 especímenes del orden Stomatopoda en 27 localidades a diferentes profundidades (20 a 73 m) durante tres cruceros oceanográficos en el Pacífico Mexicano a lo largo de la plataforma continental de los estados de Oaxaca y Chiapas. Se identificaron siete especies de las familias Eurysquillidae, Lysiosquillidae y Squillidae. Squilla hancocki y Squilla parva fueron las especies más abundantes y las más frecuentemente encontradas juntas. Se obtuvieron las relaciones entre la longitud total y la longitud del caparazón para estas dos especies; que indican que con una misma longitud total los machos de S. hancocki tienen una longitud del caparazón mayor que las hembras, mientras que para S. parva sucede lo contrario. Se registraron longitudes totales más grandes a las reportadas previamente para Lysiosquilla panamica y Squilla mantoidea. Squilla bigelowi se registró por primera vez en el área. Todas las especies se encontraron en la plataforma intermerdia (25-60 m); E. Veleronis, S. Hancocki y S. parva se distribuyeron hasta la plataforma externa (60-120 m) y S. hancocki y S. parva abarcaron la zona circalitoral (10-25 m). |
