Schuster, Guenter A., Taylor, Christopher A. & Adams, Susan B., 2015, Procambarus (Girardiella) holifieldi, a new species of crayfish (Decapoda: Cambaridae) from Alabama with a revision of the Hagenianus Group in the subgenus Girardiella, Zootaxa 4021 (1), pp. 1-32 : 30

Distribution of Hagenianus Group Taxa

Procambarus barbiger is found in south-central Mississippi in the headwaters of the Pearl and Pascagoula river drainages in Jasper, Newton, Rankin, Scott and Smith counties. Procambarus hagenianus hagenianus is known in Mississippi from the western tributaries of the upper Tombigbee River in Chickasaw, Kemper, Lowndes, and Oktibbeha counties and from disjunct populations in Rankin and Hinds counties, near Jackson, and in Alabama from the Tombigbee River drainage in Hale and Sumter counties and the Alabama River drainage in Perry County. Procambarus hagenianus vesticeps is found in Mississippi in the western tributaries of the Upper Tombigbee River drainage in Chickasaw, Monroe, Pontotoc and Oktibbeha counties, and in the Yazoo River drainage near Carrolton, Carroll County. Fitzpatrick (1978a) thought that the population near Muldon, Monroe County, Mississippi, might represent a hybrid zone for the two subspecies. He indicated that individual Form I males from that population exhibited extreme variation in the development of the beard on the margin of the palm of the chelae. Some individuals had very few long setae, reminiscent of P. h. hagenianus , whereas others had a dense beard more typical of P. h. vesticeps . Procambarus holifieldi is currently known only from the type locality in Perry County, Alabama, in the Alabama River drainage.
