Diagnosis. -Characters that distinguish U. montereus are: total length up to 40 mm; base color of body dark fuscous brown to light tan, keels of metasoma and pedipalps often contrastingly darker than surrounding cuticle; frontal margin of carapace deeply bilobed, median ocelli small, ratio of carapace width to diameter of diad 6.0-8.3 (x = 7.0 ± 0.6, n = 30); chelicera lacking crenulations on ventral margin of movable finger, superior tine of movable finger with one (rarely two) subdistal tooth; pedipalps with palm swollen obliquely toward prodorsal keel, ratio of chela length to palm width 2.6-3.1 (x = 2.9 ± 0.1, n = 30), ratio of palm width to depth 0.6--0.8 (x = 0.7 ± 0.05, n = 30); supernumerary denticles six on fixed finger, seven on movable finger (Fig. 16), primary row denticles in six subrows on fixed and movable fingers; telotarsi with single row of fine spinulae ventrally, this flanked pro- and retrolaterally by a row of four stout spiniform setae; pectine teeth 10-12 in males, 8-10 in females. This species is related to U. sequoia in structure, but differs in having primary row denticles of fixed pedipalp finger divided into six (not five) subrows.

distribution: NORTH AMERICA. USA (California): Alameda and San Mateo counties-south to Los Angeles County, from sea level to 700 m elevation.

notes: 
WILLIAMS & SAVARY 1991
This is the most broadly distributed and frequently encountered member of the genus, but it is never locally abundant. It can be encountered throughout the year by turning rocks and other ground surface debris. Females with associated litters were recorded from the Monterey area from July and December. Litters ranged in size from 21-50 offspring (oX' = 34 ± 11, n = 5). One specimen in the CAS collection has a Sedona, Coconino County, Arizona locality label but is probably incorrectly labeled because there is no other evidence that this species ranges east of coastal California.
