Material examined. We have examined 56 specimens.

Distribution. Specimens ( Fig. 184 View FIGURE 184 ) are known from Amador, Calaveras, Napa, Solano, and Yolo counties, on both sides of the Central Valley, in central California.

Diagnostic description. Total length 1.00– 1.20 mm; greatest width 0.55–0.61 mm. Reddish brown; oval in shape ( Fig. 19 View FIGURES 19–27 ). Head. Finely, sparsely punctate; a larger puncture on each side of stem of epistomal suture; shining, with transverse substriate microsculpture. Eyes absent. Antenna ( Fig. 185 View FIGURES 185–192 ) with antennomere 2 slightly longer than 3; antennomeres 5 and 6 subequal; antennomeres 7 and 8 subequal; antennomeres 9 and 10 each with a single sensory vesicle indicated apically by a protruding flange. Pronotum. Finely punctate, punctures separated by 2–4 diameters; shining, with transverse substriate microsculpture. Widest near base, sides roundly narrowing to apex; apical margin weakly emarginate, basal margin nearly straight; apical angles rounded, basal angles narrowly rounded. Elytra. Moderately finely punctate; punctures in longitudinal rows anteromedially; punctures joined by fine transverse strioles. Joined elytra slightly wider than pronotum; widest at base, roundly narrowing to apex.

Legs. Protibia ( Fig. 186 View FIGURES 185–192 ) slender; spinose on apical one-half of outer margin and apically; apical one-half of inner margin finely, densely spinose. Mesotibia ( Fig. 187 View FIGURES 185–192 ) slender; strongly spinose on outer margin and apically; exceptionally long spine at middle of outer margin. Metatibia ( Fig. 188 View FIGURES 185–192 ) slender, straight; outer margin with fine spines and a strong spine near apex; apex strongly spinose. Metafemur ( Fig. 188 View FIGURES 185–192 ) slender. Male protarsomeres ( Fig. 186 View FIGURES 185–192 ) weakly expanded, bearing elongate setae laterally and thin, colorless, transverse phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 192 View FIGURES 185–192 ) carinate; longitudinal carina with toothlike expansion near middle; depressed but not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 189, 190 View FIGURES 185–192 ) broad, moderately flat; apex flat with narrow, rounded tip. Inverted internal sac ( Fig. 190 View FIGURES 185–192 ) with distinctive hourglass-shaped sclerite apically and two rows of inwardly directed spines basally. Parameres ( Figs. 189–190 View FIGURES 185–192 ) elongate, extending beyond apex of median lobe, moderately wide, somewhat constricted before flat apices; each bearing two closely spaced setae before apex. Spermatheca. Elongate ( Fig. 191 View FIGURES 185–192 ), sinuate, tubular.

Etymology. The name minutus, Latin , small, refers to the small size of this species.
