Additional material examined. We examined 64 additional specimens (see Appendix) for a total of 181 specimens.

Distribution. Specimens ( Fig. 184 View FIGURE 184 ) are known from Marin and San Mateo counties, on both sides of the mouth of San Francisco Bay, in the Coastal Ranges of California.

Diagnostic description. Total length 1.00– 1.08 mm; greatest width 0.54–0.58 mm. Reddish brown; oval in shape ( Fig. 18 View FIGURES 11–18 ). Head.

Pronotum. Finely punctate, punctures separated by 2–4 diameters; shining, with transverse substriate microsculpture. Widest at base, sides roundly narrowing to apex; apical margin weakly emarginate, basal margin nearly straight; apical angles rounded, basal angles about rectangular. Elytra. Moderately finely punctate; punctures in longitudinal rows and joined by fine transverse strioles. Joined elytra slightly wider than pronotum, widest in basal one-fourth, roundly narrowing to apex. Legs. Protibia ( Fig. 177 View FIGURES 176–183 ) slender; spinose on outer margin and apically; densely, finely spinose on apical three-fifths of inner margin. Mesotibia ( Fig. 178 View FIGURES 176–183 ) moderately slender, straight; strongly spinose on outer margin and apically. Metatibia ( Fig. 179 View FIGURES 176–183 ) slender, straight; outer margin and apex spinose; small spines on apical one-third of inner margin. Metafemur ( Fig. 179 View FIGURES 176–183 ) moderately slender. Male protarsomeres ( Fig. 177 View FIGURES 176–183 ) weakly expanded, bearing elongate setae laterally and broad, thin, colorless phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 183 View FIGURES 176–183 ) carinate; longitudinal carina with toothlike expansion near middle; not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 180, 181 View FIGURES 176–183 ) broad, moderately flat; apex flat, weakly ogival in shape with narrowly rounded tip. Inverted internal sac ( Fig. 181 View FIGURES 176–183 ) with a pair of elongate structures. Parameres ( Figs. 180, 181 View FIGURES 176–183 ) elongate, broad, extending beyond apex of median lobe; apices flat; each bearing one long and two short setae before apex. Spermatheca. Elongate ( Fig. 182 View FIGURES 176–183 ), sinuate, tubular.

Etymology. The name marinensis refers to the abundance of this species in Marin Co., California.
