Abstraet: Samples of benthic macrofauna wcre collected by trawl and grab-dredge during seasonal cruises along thrce transccts on the coastal shelf of Southern Sinaloa. Mcxico (SIPCO cruises) from 27 to 117 m and included 6 spccies of stomatopods. Squilla biformis Bigelow and S. parva Bigelow weTe the 1110st abun dant species. AH species were found in shallow water (31-75 m) except Squilla biformis which occurred mostIy below 100 m, wherc dissolved Qxygen concentration was lower than 0.6 miL. Othe! specics found are: Squillo panamensis Bigelow, S. hancocki Schmitt, Meiosquilla swetti (Schmitt) and Eurysquilla veleronis (Schmitt).

Stomatopods of Ihe Eastern Pacific Region mantis shrimp occur. And thrid, there is still a are well·known and up to 46 species or subspe considerable lack of adequate infonnation cies are presently recognized in tbis geograph regarding Ihe ecology and Ihe geographie distri ical area. A large series of publications, most of butian of many species, despite Ihe fact Ihat Ihem by Raymond B. Manning, of Ihe Smith Ihe taxonomy of the group is presently well sonian Institution, have recently been produced docwnented. The SIPCO Project ("Sinaloa, and have provided a very valuable and long Continental Platfonn") was initiated in 1980 as awaited taxonomic and phylogenetic reorga a first step towards a complete survey of Ihe nization of this group of crustaceans (Manning, Gulf of California, and was later continued as 1961; 1963; 1968; 1970; 1971; 1972a; 1972b; an exploratory sampling program in Ihe entire 1972c; 1974; 1976; Reaka and Manning, 1980; gulf (Cortés Project in 1982) (Hendrickx, 1981). 1984). The aim af this paper is to present Stomatopods, commonly known as mantis infonnation on stomatopads galhered during shrimp ("catalina de mar" in México). represent Ihe sampling program a10ng Ihe coast of an important group of species in Ihe Gulf of Southem Sinaloa, Mexico.
