Diagnosis. Males can be diagnosed on the basis of a unique conformation of the tibia I mating apophysis and TSrd spination pattern (Figs 165 - 167. Like Aptostichus icenoglei, the Aptostichus isabella tibial I apophysis (Figs 165, 167) is rectangular in shape and bears a distal spine. In all other Aptostichus species the tibial I apophysis is triangular, rounded, or absent, with the exception of Aptostichus cabrillo which has a similar rectangular apophysis. Aptostichus isabella males can be differentiated from Aptostichus icenoglei and Aptostichus cabrillo males on the basis of the TSr (Figs 165, 167) spination pattern. The TSr of Aptostichus isabella consists of a number of spines offset proximally with no TSrd spines whereas Aptostichus icenoglei and Aptostichus cabrillo have 2 - 4 non-overlapping TSrd spines.
Etymology. The specific epithet is a noun taken in apposition from the type locality, Lake Isabella.
