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.
