The G. puncticulata species group of Rivas (1963) was shown to be a monophyletic group separable from the remainder of the G. affinis species group of Rosen and Bailey (1963). The G. puncticulata species group (named the G. puncticulata complex by Fink, 1971a) was reviewed and found to consist of three subgroups. The first subgroup (I) is the G. yucatana complex occurring on the mainland of Mexico and Central America. The second and third subgroups, puncticulata (II) and hubbsi (III) forms, are sister groups within the G. puncticulata complex restricted to the Antilles. The puncticulata forms (group II) consist of the populations from Cuba, Jamaica and the Cayman Islands called G. p. puncticulata by Fink (1971a) and previously called G. puncticulata, G. howelli, G. oligosticta and G. caymanensis. The hubbsi forms (group III) consist of populations previously called G. bucheri, G. baracoana, G. monticola (Cuban), G. manni (Lake Cunningham, New Providence Island, Bahamas) and G. hubbsi (variable salinities, Bahamas).
