abstract
Procambariis (Girardiella) cendeus is a new burrowing crawfish known from two localities in the Brazos River drainage of Brazos County, Texas. Although it shares many key characters with the members of the Gracilis Group of the subgenus, the following combination of characters will distinguish the species: presence of cephalic process in the male; prominent caudal knob surmounted by conspicuous caudal process in the male; unbearded palm; narrow areola; rostrum lacking marginal spines or tubercles; and female annulus ventralis that is subcircular in outline.
