DISTRIBUTION Species and genera—As shown in Figure 70, the western chonaphine species occupy mutually exclusive ranges, segregated from each other, aside from the region in and around Idaho, where C. armata and Montaphe elrodi overlap broadly; the former also overlaps Metaxycheir prolata, and the latter completely envelops C. schizoterminalis. The sympatry in California between S. sinuata and arcuata may be an artifact because so few records are available from the Coast Range in Lake, Mendocino, Trinity, and Humboldt counties. The northernmost, Humboldt County, population of S. arcuata may be allopatric and detached from the rest of the species, which occurs generally to the south-southwest of S. sinuata. I have assumed that these populations connect, which accounts for the range overlap with S. sinuata; if they do not overlap, S. arcuata and sinuata are parapatric. Both S. sinuata and Montaphe elrodi show southward projecting fingers from their.
