Abstract

A new locality for the species in Conecuh County, Alabama, is recorded. Specimens collected ranged from 31 to 120 mm snout to vent. Sexual maturity apparently occurs at about 100 mm body length in females, and near 80 mm in males. Mature males have no melanophores on the testis and no mental gland. Number of lobes of testes increases with increasing body length. The presence of a few large ovarian ova in 2 females suggests that there is probably no free-living, aquatic larva. Phaeognathus hubrichti seems able to start its own burrows only in loosely packed soil, but can enlarge and use previously formed cavities and tunnels. Gut contents of P. hubrichti and Plethodon glutinosus are similar, and differ from those of Desmognathus monticola. P. hubrichti feeds at the burrow entrance on surface-dwelling food. All specimens of P. hubrichti examined were infested with intestinal flukes and colic roundworms.
