Wrong genus.
Lysiosquillina glabriscula has fewer fewer spines on the dactyl (6-7), a broader antennal scale that has dark spots in the center, and has a smooth telson. Also, it has not been recorded west of Florida.
This animal is Lysiosquilla scabricauda. The telson is rough (particularly in females), the antennal scales are more narrow and do not have a dark center spot, and it has 9-12 spines on the dactyl. This is a very common species from South Carolina and Bermuda to Texas and throughout the Gulf of Mexico south to Brazil. Maximum size is around 27 cm.
