Diagnostic description. Body yellowish brown, moderately shining; antennomeres 7–10 darker, apical antennomere paler. Small species, length of pronotum + elytra = 1.9–2.1 mm (males), 1.9–2.0 mm (females). Head finely punctate with dense microsculpture of irregular lines. Pronotum broad, widest at basal one-third, sides rounded, basal angles obtuse; ratio length:width = 1:1.6; minutely punctate, some punctures joined by fine lines of microsculpture. Elytra short, ratio length:width = 1:0.8; with 9 punctate striae; stria 1 impressed in apical one-half; striae 6 and 7 do not reach apex; intervals with a single row of fine punctures and transversely striolate; uneven intervals with scattered larger punctures. Antennal club ( Fig. 88 View FIGURES 88–93 ) moderately broad, ratio club width:length = 1:2.8; width ratio of antennomeres 7:8:9 = 1.3:1:1.5. Mandibles ( Fig. 89 View FIGURES 88–93 ) stout, a thin plate forming inner apical margins. Labrum entire. Male profemur ( Fig. 90 View FIGURES 88–93 ) with small tooth at middle of posterior margin; female profemur unarmed; mesofemur of both sexes unarmed; male metafemur with denticle at middle of posterior margin; female metafemur unarmed. Protibia of male and female broad in apical half; mesotibia of male strongly angulate at basal one-third, broad at apex; mesotibia of female slender, unmodified; metatibia slender, unmodified in both sexes; all tibiae of both sexes spinose on outer margins.

Male. Aedeagus ( Fig. 91 View FIGURES 88–93 ) with median lobe broad, gently tapered to broad apex. Parameres inserted at basal one-fifth of median lobe, flat, nearly reaching apex of median lobe, apices multisetose. Small notch at basal one-third of lateral margin of each paramere. Female. Coxites ( Fig. 93 View FIGURES 88–93 ) short, broad, with apical setae; no visible styli. Sternite 8 ( Fig. 92 View FIGURES 88–93 ) weakly emarginate apically; anterior apophysis narrow, parallel-sided.

Distribution. The species occurs in forested habitats in the coastal mountains of central and southern California ( Fig. 94 View FIGURE 94 ).

Field notes and habitats. Almost all adults were taken in flight intercept traps in seasonal mixed forests in protected canyons.

Seasonality. Adults of the species were collected in the cool-wet spring months of March (5), April (4) and May (1).

Etymology. Named with reference to the state of California, to which the species is seemingly endemic.
