Diagnosis
Diagnosis. Based on morphological features alone (Figs 98-103) this species can be difficult to diagnose from geographically proximate sibling species, Aptostichus stanfordianus, Aptostichus angelinajolieae, and Aptostichus stephencolberti but can be distinguished on the basis of a set of unique mtDNA nucleotide substitutions (see Bond and Stockman 2008). The species is restricted in distribution to the coastal dune habitats of Marin, Sonoma, Mendocino, Humboldt, and Del Norte Counties (California). Individuals of Aptostichus stanfordianus, found only in inland habitats,are much darker in coloration whereas Aptostichus miwok specimens are much lighter (Figs 104, 105).
Description
Description. Described by Bond (2008).
Distribution
Distribution and natural history. Aptostichus miwok is distributed throughout the geographically disjunct coastal dune habitats of Del Norte, Humboldt, Mendocino, Sonoma, Marin, and San Francisco counties of central and northern California (Map 8). A single inland specimen (Humboldt) is placed with this species on the basis of the molecular data. The DM for Aptostichus miwok (Map 9) corresponds closely to the known occurrences with the largest areas of high probability of occurrence in the more northern extent of the species' distribution. The model indicates that inland localities may be suitable despite the paucity of known inland populations. The habitat requirements and general burrow structure is very similar to that described for Aptostichus stephencolberti. All populations are located in the coastal dune habitat. Males have been collected in the months of September, November, January, March, and April.
