Material examined. We have examined 9 specimens.

Distribution. Specimens ( Fig. 136 ) are known only from Del Norte County, California and Josephine County, Oregon, in the Klamath Mountains.

Diagnostic description. Total length 1.34–1.40 mm; greatest width 0.68–0.70 mm. Dark reddish brown; elongate-oval in shape ( Fig. 16 ). Head. With scattered minute punctures; shining, with transverse substriate microsculpture posteriorly. Eyes absent. Antenna ( Fig. 160 ) with antennomeres 2 and 3 subequal in length; antennomere 5 wider than 4, longer than 6; antennomere 7 slightly longer but not wider than 8; antennomeres 9 and 10 each with a single sensory vesicle indicated apically by a protruding flange. Pronotum. Minutely punctate, punctures separated by 2–5 diameters; shining, with transverse substriate microsculpture. Widest at base, sides curving to narrower apex; apical margin weakly emarginate, basal margin nearly straight; apical angles broadly rounded, basal angles narrowly rounded. Elytra. Finely punctate; punctures in serial rows but strial not impressed, obscure apically; punctures joined by fine transverse strioles. Joined elytra slightly wider than pronotum, widest near base; roundly narrowing to apex. Legs. Protibia ( Fig. 161 ) slender; apex spinose; apical one-half of outer margin with three small spines; apical three-fifths of inner margin finely, densely spinose. Mesotibia ( Fig. 162 ) slender; strongly spinose on outer margin and apically, with elongate spine near middle of outer margin; apical one-third of inner margin with small spines. Metatibia ( Fig. 163 ) slender, weakly curved; apex spinose; two spines on apical one-half of outer margin; apical one-half of inner margin spinose. Metafemur ( Fig. 163 ) slender. Male protarsomeres ( Fig. 161 ) weakly expanded, bearing elongate setae laterally and thin, colorless, transverse phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 167 ) carinate; longitudinal carina with large toothlike expansion near middle; slightly sloping to transverse carina; not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 164, 165 ) broad, evenly narrowed to flattened apex. Internal sac ( Figs. 164, 165 ) with two pairs of large spines. Parameres ( Figs. 164, 165 ) moderately slender, elongate, with flattened apices; extending beyond apex of median lobe; each bearing two closely spaced setae before apex. Spermatheca. Elongate ( Fig. 166 ), tubular, swollen medially; narrowly, transversely ribbed throughout length.

Etymology. The name klamathensis refers to the occurrence of this species in the Klamath Mountains of SW Oregon and NW California, USA.
