Distribution.
Specimens (
Fig. 310
) are known only from Curry County in southwestern
Oregon
.
Diagnosis
.
Total length
1.40–1.60 mm
; greatest width
0.65–0.80 mm
. Reddish brown; elongate-oval in shape (
Fig. 34
).
Head
. Moderately finely, irregularly punctate; with reticulate microsculpture. Eyes absent. Antenna (
Fig. 311
) with antennomere 2 longer than 3; antennomere 5 slightly larger than 4 and 6; antennomere 7 clearly larger than 8; antennomeres 9 and 10 lack visible sensory vesicles.
Pronotum
. Finely punctate, punctures separated by 3– 4 diameters; with reticulate microsculpture. Disc with three pairs of larger punctures, positioned subapically, posteromedially and subbasally. Slightly wider at middle than at base, narrowing to apex; apical margin weakly emarginate, basal margin straight; apical angles rounded, basal angles weakly obtuse.
Elytra
. Moderately coarsely punctate; a few striae weakly indicated adjacent to suture; punctures joined by fine strioles that create a weakly imbricate pattern basally. Joined elytra slightly wider than pronotum; sides subparallel in basal one-half, narrowing to apex.
Legs
. Protibia (
Fig. 312
) narrow at base, apical one-half strongly widened in male, less so in female; two curved spines at apex of outer margin; apical one-half of inner margin with fine, dense spines. Male mesotibia (
Fig. 313
) with basal two-thirds sinuate, angulate at apical one-third; unmodified in female; strong spines on outer margin in both sexes. Metatibia (
Fig. 314
) elongate, narrow, straight in both sexes. Metafemur (
Fig. 314
) slender in both sexes. Male protarsomeres (
Fig. 312
) bearing elongate setae laterally and thin, colorless, broad phanerae ventrally. Mesotarsomeres without phanerae.
Venter
. Mesoventrite (
Fig. 318
) carinate, with a small median tooth; excavation behind transverse carina.
Male genitalia
. Median lobe of aedeagus (
Figs. 315, 316
) cylindrical, curved, with flattened apex narrowing to weak rounded lobe. Inverted internal sac (
Fig. 316
) with elongate sclerotized structures. Parameres (
Figs. 315, 316
) narrow, about three-fourths length of median lobe; each paramere with one apical and one subapical seta.
Spermatheca
. Tubular (
Fig. 317
), curved.
