Additional material examined. We examined 934 specimens additional to those listed above (See Appendix) for a total of 1031 specimens.

Distribution. Specimens ( Fig. 136 View FIGURE 136 ) are known only from Del Norte and Humboldt counties in northwestern Califonria.

Diagnostic description. Total length 1.32–1.46 mm; greatest width 0.82–0.86 mm. Reddish brown; oval in shape ( Fig. 14 View FIGURES 11–18 ). Head. Finely, sparsely punctate, shining, with faint reticulate microsculpture on vertex. Eyes absent. Antenna ( Fig. 145 View FIGURES 145–152 ) with antennomeres 2 and 3 subequal in length; antennomere 5 wider than 4, subequal to 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. Minutely, sparsely punctate; with reticulate microsculpture. Widest at base, nearly as wide as elytra; sides rounded, narrowing to apex; apical margin weakly emarginate, basal margin nearly straight; apical angles broadly rounded, basal angles narrowly rounded. Elytra. Finely punctate; punctures in obscure longitudinal rows; with fine, widely spaced transverse strioles. Joined elytra slightly wider than pronotum, widest at basal one-fourth, narrowing to apex. Legs. Protibia ( Fig. 146 View FIGURES 145–152 ) slender; apical two-thirds of outer margin and apical margin spinose; apical three-fifths of inner margin with fine spines. Mesotibia ( Fig. 147 View FIGURES 145–152 ) slender, straight; strongly spinose apically; a large, elongate spine at middle of outer margin. Metatibia ( Fig. 148 View FIGURES 145–152 ) slender, nearly straight; strong spines apically; smaller spines on apical three-fifths. Metafemur ( Fig. 148 View FIGURES 145–152 ) slender. Male protarsomeres ( Fig. 146 View FIGURES 145–152 ) feebly or not dilated, bearing elongate setae laterally and thin, broad, colorless phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 152 View FIGURES 145–152 ) carinate; longitudinal carina with a toothlike expansion near middle; transverse carina on different plane than longitudinal carina; not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 149, 150 View FIGURES 145–152 ) broad with flat, dorsally depressed, rounded apex. Inverted internal sac ( Fig. 150 View FIGURES 145–152 ) with two pairs of elongate, narrow structures near middle; posteriorly with a distinctive elongate, dark structure bearing spines. Parameres ( Figs. 149, 150 View FIGURES 145–152 ) moderately narrow, extending to near apex of median lobe; with flat, deflexed apices, each bearing two closely spaced setae before apex. Spermatheca. Elongate ( Fig. 151 View FIGURES 145–152 ), tubular, sinuate.

Etymology. The name humboldtensis refers to the abundance of this species in Humboldt Co., California.
