Total length 1.32–1.46 mm; greatest width 0.82–0.86 mm. Reddish brown; oval in shape (Fig. 14). <b>Head</b>. Finely, sparsely punctate, shining, with faint reticulate microsculpture on vertex. Eyes absent. Antenna (Fig. 145) 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. <b>Pronotum</b>. 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. <b>Elytra</b>. 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. <b>Legs</b>. Protibia (Fig. 146) slender; apical two-thirds of outer margin and apical margin spinose; apical three-fifths of inner margin with fine spines. Mesotibia (Fig. 147) slender, straight; strongly spinose apically; a large, elongate spine at middle of outer margin. Metatibia (Fig. 148) slender, nearly straight; strong spines apically; smaller spines on apical three-fifths. Metafemur (Fig. 148) slender. Male protarsomeres (Fig. 146) feebly or not dilated, bearing elongate setae laterally and thin, broad, colorless phanerae ventrally. Mesotarsomeres without phanerae. <b>Venter</b>. Mesoventrite (Fig. 152) carinate; longitudinal carina with a toothlike expansion near middle; transverse carina on different plane than longitudinal carina; not excavated behind transverse carina. <b>Male genitalia</b>. Median lobe of aedeagus (Figs. 149, 150) broad with flat, dorsally depressed, rounded apex. Inverted internal sac (Fig. 150) with two pairs of elongate, narrow structures near middle; posteriorly with a distinctive elongate, dark structure bearing spines. Parameres (Figs. 149, 150) moderately narrow, extending to near apex of median lobe; with flat, deflexed apices, each bearing two closely spaced setae before apex. <b>Spermatheca</b>. Elongate (Fig. 151), tubular, sinuate. <b>Etymology.</b> The name <i>humboldtensis</i> refers to the abundance of this species in Humboldt Co., California.
