Pinodytes capizzii ( Hatch, 1957) , new combination

( Figs. 32 , 274 , 292–301 )

Catopocerus capizzii Hatch 1957: 21 .

Type material. Type male in USNM, seen. Type label data: Humbug Mt. , Curry County, Oregon ; 22.V.1955, J. Capizzi.

Additional material examined. We examined 1003 additional specimens (see Appendix) for a total of 1004 specimens.

Distribution. Specimens ( Fig. 274 ) are known from Benton, Clackamas, Columbia, Coos, Curry, Douglas, Harney, Lane, Lincoln, Linn, Marion, Polk, Tillamook, and Yamhill counties, Oregon, and Thurston County, Washington.

Diagnosis. Total length 1.50–1.70 mm; greatest width 0.76–0.81 mm. Reddish brown; oval in shape ( Fig. 32 ).

Head. Finely, sparsely punctate, shining, with reticulate microsculpture. Eyes absent. Antennae ( Fig. 292 ) with antennomere 2 wider and slightly longer than 3; antennomere 5 slightly larger than 4 and 6; antennomere 7 clearly longer and slightly wider than 8; antennomeres 9 and 10 lack visible sensory vesicles. Pronotum. Finely, sparsely punctate, shining, with reticulate microsculpture. Widest near base; sides slightly rounded, narrowing to apex; apical margin emarginate; basal margin weakly sinuate on each side; apical angles rounded, basal angles subrectangular. Elytra. Punctation irregular, punctures larger than on pronotum, separated by 2–4 diameters; punctures joined transversely by fine strioles. Joined elytra slightly wider than pronotum, widest in basal one-third, narrowing to apex. Legs. Protibia ( Fig. 293 ) triangular, broad at apex; two large spines near apex of outer margin; apical onehalf of inner margin with fine, dense spines. Mesotibia ( Fig. 294 ) evenly widened to apex; strong spines on outer margin, apically and on apical one-half of inner margin. Metatibia ( Fig. 295 ) weakly sinuate in most males, not sinuate in females, narrow in basal one-third, widening in apical two-thirds, with strong spines apically. Metafemur ( Fig. 295 ) slender. Male protarsomeres ( Fig. 293 ) expanded, bearing elongate setae laterally and thin, colorless, transverse phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 301 ) carinate, longitudinal carina with one small tooth; excavation behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 296, 297 ) elongate, broad, sinuate before expanded flattened apex; strongly curved at middle, nearly rightangled in lateral view. There is geographical variation in the shape of the aedeagal apex ( Figs. 298, 299 ). Everted internal sac ( Fig. 296 ) with various shapes and sizes of spines and a small sclerite ventrally near apex. Parameres ( Figs. 296, 297 ) narrow, not reaching apex of median lobe; each bearing two setae apically. Spermatheca. tubular ( Fig. 300 ), curved.

Bionomics. Specimens have been found associated with sporocarps of hypogeous fungi ( Fogel and Peck 1975).
