 Material examined. We have examined 91 specimens.   
 Distribution. Specimens (Fig. 184) are known from Del Norte, Humboldt, and Mendocino counties in the Coastal Ranges of northern California, and from Contra Costa County on the south side of San Francisco Bay.   
 Diagnostic description. Total length 1.20–1.36 mm; greatest width 0.66–0.74 mm. Reddish brown to dark brown; oval in shape (Fig. 21). Head. Finely, sparsely punctate; a larger puncture on each side opposite posterior one-half of stem of epistomal suture; shining, with transverse substriate microsculpture. Eyes absent. Antenna (Fig. 201) 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. Finely punctate, punctures separated by 2–4 diameters; shining, with transverse substriate microsculpture. Widest at base, weakly narrowing in apical one-half; apical margin weakly emarginate, basal margin nearly straight; apical angles rounded, basal angles about rectangular. Elytra. Moderately finely punctate; punctures not arranged in longitudinal rows except basally near suture; punctures joined by fine transverse strioles. Joined elytra slightly wider than pronotum; widest in basal one-third, roundly narrowing to apex. Legs. Protibia (Fig. 202) slender; width increases evenly from base to apex; spinose near apex and apically; densely, finely spinose on apical one-half of inner margin. Mesotibia (Fig.203) moderately slender; strongly spinose on outer margin and apically; spine at apical one-fourth of inner margin. Metatibia (Fig. 204) slender, straight; outer margin with strong spines near apex and one-third from apex; apex spinose; small spines on apical one-half of inner margin. Metafemur (Fig. 204) slender. Male protarsomeres (Fig. 202) weakly expanded, bearing elongate setae laterally and broad, thin, colorless phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite (Fig. 208) carinate; longitudinal carina with large toothlike expansion near middle; depressed but not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus (Figs. 205, 206) elongate; apex flat, moderately narrow with rounded apex. Inverted internal sac (Fig. 206) with two pairs of elongate sclerotized structures. Parameres (Figs. 205, 206) elongate, moderately narrow, extending beyond apex of median lobe; apices flat, each bearing two setae before apex. Spermatheca. Elongate (Fig. 207), bulbous at apex.   
 Etymology. The name parvus, Latin, little, refers to the small size of this species.
