Distribution.
Specimens (
Fig. 310
) are known from Mendocino County,
California
and Clackamas, Clatsop, Columbia, Coos, Douglas, Hood River, Marion, Multnomah, Polk, Tillamook, Wasco,
Washington
, and Yamhill counties,
Oregon
.
Diagnosis
.
Total length
1.56–1.70 mm
; greatest width
0.76–0.81 mm
. Reddish brown; elongate-oval in shape (
Fig. 33
).
Head
. Finely, sparsely punctate, with reticulate microsculpture. Eyes absent. Antennae (
Fig. 302
) with antennomere 3 shorter and narrower than 2; antennomere 5 larger than 4 and 6; antennomere 7 clearly larger than 8; antennomeres 9 and 10 without visible sensory vesicles.
Pronotum
. Finely, sparsely punctate, with reticulate microsculpture. Widest sub-basally, slightly narrower than elytra; sides rounded, converging in apical one–half; apical margin weakly emarginate; basal margin nearly straight; apical angles rounded, basal angles nearly rightangled.
Elytra
. Punctation variable in size, larger than pronotal punctation; variable spaced; punctures joined by fine transverse strioles. Sub–basally with a clearly impressed transverse striole connecting a transverse row of punctures. Joined elytra widest at basal one-third; narrowing to apex.
Legs
. Protibia (
Fig. 303
) of male broad at apex, triangular, narrower in female; outer margin with a few spines on apical one-half; inner margin with dense small spines on apical one-half. Mesotibia (
Fig. 304
) evenly widened to apex; strongly spinose. Metatibia (
Fig. 305
) slender, spinose on apical one-half. Metafemur (
Fig. 305
) slender. Male protarsomeres (
Fig. 303
) not dilated, bearing elongate setae laterally and thin, colorless transverse phanerae ventrally. Mesotarsomeres without phanerae.
Venter
. Mesoventrite (
Fig. 309
) carinate; longitudinal carina not toothed; excavated behind transverse carina.
Male genitalia
.
Median lobe of aedeagus (
Figs. 306, 307
) strongly curved near middle in lateral view, flattened apically; in dorsal view, broad, with triangular apex. Inverted internal sac (Fig.
Fig. 307
) with various shapes and sizes of spines and a sclerotized curved structure. Parameres (
Figs. 306, 307
) narrow, not reaching apex of median lobe, each bearing two setae at apex.
Spermatheca
. Robust (
Fig. 308
), thickened medially, narrower at apex and base.
Bionomics.
Specimens have been found associated with sporocarps of hypogeous fungi (
Fogel and Peck 1975
).
