Pinodytes rothi ( Hatch, 1957) , new combination

( Figs. 33 , 302–310 )

Catopocerus rothi Hatch 1957: 21 .

Type material. Type male in USNM, seen. Type label data: 6 mi N Buxton , Washington County, Oregon; 6.IV.1955, V. Roth.

Additional material examined. We examined 1105 additional specimens (see Appendix) for a total of 1106 specimens.

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).
