Description
The Jemez Mountains Amphipod (Stygobromus jemezensis) is a medium sized ground water amphipod; the largest females and males are 7 mm and 4.5 mm, respectively. It appears to be closely related to S. arizonensis due to the structure of the gnathopods (the appendages on crustaceans that are used for grasping and prehension). It can be distinguished as the propod of the first gnathopod has more teeth on the palmar margin, prepod six has a distinct posterior lobe, the posterior margins of the pleonal plates have one setule, uropods one and two have more spines on the rami, uropod 3 has a proportionately broad peduncle, and the telson has short spines and a slight apical notch (Wang and Holsinger 2001).
