ABSTRACT This work is an updated checklist of Mexican Pycnogonida species for both oceans, the Mexican Pacific (PA) and the Gulf of Mexico (GMx). This research was carried out based on the first historical records by Schimkewitsch in 1893 up to the present day. The number of recorded species increased in this study. The total number of species in Mexican oceans is 58, distributed among 19 genera and 10 families. All records were cross-referenced with the original literature, and those found to be questionable were deleted from the checklist. With the data reported in this checklist, an extrapolation of the total number of species was performed using rarefaction curves, thus demonstrating that the recorded species fell well below the projected diversity.... |
