Material examined . We have examined 14 specimens . Distribution. Specimens ( Fig. 359 ) are known only from Jackson County, in southwestern Oregon . Diagnostic description . Total length 1.92–2.44 mm ; greatest width 0.84–0.92 mm . Reddish brown; elongate in shape ( Fig. 43 ). Head. Moderately finely, irregularly punctate; with a mixture of reticulate and substriate microsculpture. Eyes absent. Antenna ( Fig. 384 ) with antennomeres 2 and 3 subequal in length; antennomere 5 larger than 4, longer than 6; antennomere 7 clearly larger than 8; antennomeres 9 and 10 lack visible sensory vesicles. Pronotum . Moderately finely punctate; punctures separated by 2–3 diameters; disc with three pairs of larger punctures, positioned subapically, posteromedially and subbasally; with reticulate microsculpture. Slightly wider near middle than at base, narrowing apically; apical margin emarginate, basal margin straight; apical angles rounded, basal angles weakly obtuse. Elytra . Moderately coarse, irregular strial punctures; interstrial punctures fine; punctures joined by fine transverse strioles. Slightly wider than pronotum; sides subparallel in basal one-half, narrowing to apex. Legs . Male protibia ( Fig. 385 ) evenly widened from narrow base to broad apex; apex narrower in female; two curved spines at apex of outer margin; apical one-half of inner margin with fine, dense spines. Mesotibia ( Fig. 386 ) in male with basal two-thirds narrow, sinuate; apical one-third strongly widened; unmodified in female; strong spines on outer margin in both sexes. Metatibia ( Fig. 387 ) elongate, narrow, nearly straight in both sexes. Metafemur ( Fig. 387 ) slender. Male protarsomeres 1–3 ( Fig. 385 ) weakly widened, bearing elongate setae laterally and multiple broad, thin, colorless phanerae ventrally; protarsomere 1 longer than 2 and 3 combined. Mesotarsomeres without phanerae. Venter . Mesoventrite ( Fig. 391 ) carinate; longitudinal carina with a small median tooth; excavation behind transverse carina. Male genitalia . Median lobe of aedeagus ( Figs. 388, 389 ) cylindrical, sinuate laterally and dorsoventrally; with broad, flattened apex. Inverted internal sac ( Fig. 389 ) with a large curved sclerite and two small sclerites. Parameres ( Figs. 388, 389 ) narrow, reaching constriction at base of flattened apex of median lobe; each bearing one apical and one slightly subapical seta. Spermatheca , Tubular ( Fig. 390 ), curved. Etymology. The name sinuatus , Latin , sinuate, refers to the shape of the median lobe of the aedeagus of this species.
