Material examined. We have examined 50 specimens.

Distribution. Specimens ( Fig. 184 ) are known from Monterey and San Luis Obispo counties, in the Santa Lucia Mountains of coastal southern California.

Diagnostic description. Total length 1.50–1.64 mm; greatest width 0.70–0.80 mm. Reddish brown; elongateoval in shape ( Fig. 20 ). Head. Finely punctate, punctures separated by 1–5 diameters; a larger puncture on each side of apex of stem of epistomal suture; shining; weak substriate microsculpture on vertex and laterally. Eyes absent. Antenna ( Fig. 193 ) with antennomeres 2 and 3 subequal in length; antennomere 5 larger than 4 and 6; antennomere 7 longer but not wider than 8; antennomeres 9 and 10 each with a single sensory vesicle indicated apically by a protruding flange. Pronotum. Punctures similar in size to head punctation, separated by 2–4 diameters; shining, with weak transverse substriate microsculpture. Widest before base, sides weakly rounded, narrowing to apex; apical margin weakly emarginate, basal margin nearly straight; apical angles rounded, basal angles rectangular. Elytra. Moderately strongly punctate, punctures in longitudinal rows and joined by fine transverse strioles. Joined elytra slightly wider than pronotum; widest in basal one-half, roundly narrowing to apex. Legs. Protibia ( Fig. 194 ) moderately slender, width increases evenly from base to apex; spinose on apical one-half of outer margin and apically; fine, dense spines on apical three-fifths of inner margin. Mesotibia ( Fig. 195 ) moderately slender; strongly spinose on outer margin and apically; inner margin with smaller spines near base. Metatibia ( Fig. 196 ) slender, weakly outwardly curved in male; outer margin with a strong spine near middle; apex spinose; small spines on apical one-half of inner margin. Metafemur ( Fig. 197 ) moderately broad in both sexes. Male protarsomeres ( Fig. 194 ) expanded, bearing elongate setae laterally and broad, thin, colorless phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 200 ) carinate; longitudinal carina with large toothlike expansion near middle; not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 197, 198 ) elongate, broad, with shallow dorsal depressed area before apex; apex flattened, narrowly rounded at tip. Everted internal sac ( Fig. 198 ) with a bifurcated sclerite. Parameres ( Figs. 197, 198 ) elongate, broad, straight, with flattened apices; extending beyond apex of median lobe; each bearing two well-spaced setae before apex. Spermatheca. Elongate ( Fig. 199 ), tubular, coiled before duct.

Etymology. The name monterey , a noun in apposition, refers to the type locality of this species in Monterey Co., California.
