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.
