Sumario:Morphological data from incidental captures inthe Gulf of California of the spider crabs Maiopsis panamensisand Stenocionops ovata are presented. Sex ratios, carapacewidth and length distributions by sex, weight distribution bysex, and ovigerous female frequency are reported. Newmaximum values for the size of the branchial width of thecarapace in males of both species have been observed. 70 mmwider than previously recorded in M. panamensis and a 9.5 mmwider in S. ovata. Moreover, the presence of M. panamensisalong the West Coast of the Gulf of California has beenregistered, out of its limit of the reported distribution.
