Studies on decapod crustacea from the Indian River region of Florida. VI. The identity of Parthenope (Platylambrus) Serrata (H. Milne Edwards 1834) and Parthenope (Platylambrus) Granulata (Kingsley 1879)

While examining a relatively large collection of parthenopid crabs from continental shelf waters off both the western and eastern central Florida coasts, I found an extensive series of what I at first considered to be Parthenope (Platylambrus) serrata (H. Milne Edwards, 1834). I noticed, however, that male specimens identified as P. serrata exhibited two different forms of gonopods. One form agreed with those figured by Williams (1965) as P. serrata, while the other form could not be attributed to any species whose gonopods were illustrated in the available literature.
