California: same data as holotype, 3 ( CSCA) ; Butte Co., 5miNE Butte Meadows , 8.V.1976, F. G.

Material examined. We have examined 10 specimens.

Distribution. Specimens ( Fig. 224 View FIGURE 224 ) are known only from Butte County, on the western side of the Sierra Nevada Mountains, in northern California.

Diagnostic description. Total length 1.20–1.49 mm; greatest width 0.62–0.76 mm. Reddish brown; oval in shape ( Fig. 25 View FIGURES 19–27 ). Head. Finely, sparsely punctate; a larger puncture on each side of apex of stem of epistomal suture; shining; with reticulate microsculpture on vertex and laterally. Eyes absent. Antenna ( Fig. 233 View FIGURES 233–240 ) with antennomeres 2 and 3 subequal in length; antennomere 5 wider than 4, slightly narrower than 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 3–5 diameters; shining, with transverse, substriate microsculpture. Widest at base, narrowing in apical two-thirds; apical margin weakly emarginate, basal margin nearly straight; apical angles rounded, basal angles about rectangular. Elytra. Moderately coarsely punctate; longitudinal rows weakly discernable; punctures joined by fine transverse strioles. Slightly wider than pronotum; widest in basal onethird, roundly narrowing to apex. Legs. Protibia ( Fig. 234 View FIGURES 233–240 ) moderately slender, width increases evenly from base to apex; spinose on apical one-third of outer margin and apically; inner margin with dense fine spines on apical onehalf. Mesotibia ( Fig. 235 View FIGURES 233–240 ) moderately slender, nearly straight; strongly spinose on outer margin and apically; spinose on apical two-fifths of inner margin. Metatibia ( Fig. 236 View FIGURES 233–240 ) slender, nearly straight; outer margin with strong spines near middle and before apex; apex spinose; several fine spines on apical one-half of inner margin. Metafemur ( Fig. 236 View FIGURES 233–240 ) slender. Male protarsomeres ( Fig. 234 View FIGURES 233–240 ) weakly expanded, bearing elongate setae laterally and broad, thin, colorless phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 240 View FIGURES 233–240 ) carinate; longitudinal carina with rounded, toothlike expansion near middle; not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 237, 238 View FIGURES 233–240 ) broad; apex flattened, asymmetrical in dorsal view. Inverted internal sac ( Fig. 238 View FIGURES 233–240 ) with clusters of elongate spines and a single large, strong spine. Parameres ( Figs. 237, 238 View FIGURES 233–240 ) elongate, longer than median lobe, with flattened, deflexed apices; each bearing two setae before apex. Spermatheca. Elongate ( Fig. 239 View FIGURES 233–240 ), tubular, ribbed.

Etymology. The name spinus, Latin , spine, refers to the distinctive large spine of the internal sac of the aedeagus of this species.
