Pinodytes imbricatus ( Hatch, 1957) , new combination

( Figs. 30 , 274–282 )

Catopocerus imbricatus Hatch 1957: 20 .

Type material. Type female in USNM, seen. Type label data. 6 mi N Buxton , Washington Co., Oregon; 6.IV.1955, W. Roth, from duff.

Additional material examined. We examined 14 additional specimens (see Appendix)

for a total of 15 specimens.

Distribution. Specimens ( Fig. 274 ) are known only from Tillamook and Washington counties in northwestern Washington.

Diagnosis. Total length 3.20–3.60 mm; greatest width 1.32–1.52 mm. Reddish brown; elongate in shape ( Fig. 30 ). Head. Moderately finely punctate, punctures separated by 1–2 diameters or less; with both reticulate and substriate microsculpture. Eyes absent. Antenna ( Fig. 275 ) with antennomere 3 slightly longer than 2; antennomere 5 longer than 4 and 6; antennomere 7 clearly larger than 8; antennomeres 9 and 10 lack visible sensory vesicles. Pronotum. Evenly, moderately finely punctate, punctures separated by 1–2 diameters; with a few larger punctures, usually paired; with reticulate microsculpture. Slightly wider at middle than at base, sides weakly rounded; apical margin emarginate, basal margin straight; apical angles rounded, basal angles weakly obtuse. Elytra. Strial punctures moderately coarse; striae impressed in basal one half; interstrial punctures moderately fine; with imbricate microsculpture basally, stronger in females. Joined elytra slightly wider than pronotum; sides subparallel in basal one-half, narrowing apically. Legs. Protibia ( Fig. 276 ) broad at apex in male, narrower in female; two curved spines at apex of outer margin; apical one-half of inner margin with fine, dense spines. Mesotibia ( Fig. 277 ) weakly curved in male, straight in female; with strong spines on outer margin and apically, fine spines on apical one-half of inner margin. Metatibia ( Fig. 278 ) slender, weakly widened apically. Metafemur ( Fig. 278 ) slender. Male protarsomeres ( Fig. 276 ) bearing elongate setae laterally and thin, colorless, transverse phanerae ventrally. Protarsomere 1 elongate. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 282 ) carinate, with a small median tooth; excavation behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 279, 280 ) elongate, broad, evenly curved in basal one-half; sharply angulate before slightly narrowed, flattened apex. Inverted internal sac ( Fig. 280 ) with asymmetrical sclerotized structures. Parameres ( Figs. 279, 280 ) slender, about two-thirds length of median lobe; each paramere bearing one apical and one sub-apical seta. Spermatheca. Tubular ( Fig. 281 ), sharply curved near middle.

Pinodytes newelli ( Hatch, 1957) , new combination

( Figs. 31 , 274 , 283–291 )

Catopocerus newelli Hatch 1957: 20 .

Type material. Type male in USNM, seen. Type label data: Coos Head , Coos County, Oregon ; 14.IX.1947, J. M. Newell.

Additional material examined. We examined 402 additional specimens (see Appendix)

for a total of 403 specimens.

Distribution. Specimens ( Fig. 274 ) are known from Benton, Clatsop, Columbia, Coos, Curry, Douglas, Lane, Lincoln, Tillamook, and Washington counties, Oregon, and Grays Harbor County, Washington in the Coastal Range mountains.

Diagnosis. Total length 1.60–2.60 mm; greatest width 0.64–1.00 mm. Reddish brown to dark reddish brown; elongate in shape ( Fig. 31 ). Head. Moderately finely punctate, punctures separated by 1–4 diameters, with a mixture of reticulate and substriate microsculpture. Eyes absent. Antennae ( Fig. 283 ) with antennomere 2 slightly 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. Moderately finely punctate, punctures separated by 2–3 diameters; with reticulate microsculpture. Posterior one-half of about equal width, then narrowing to apex; apical margin emarginate, basal margin straight; apical angles rounded, basal angles sub-rectangular. Elytra. Moderately coarsely punctate; a few striae weakly indicated adjacent to suture; punctures joined by fine strioles that create a weak imbricate pattern basally; joined elytra about as wide as pronotum, sides sub-parallel in basal one-half, narrowing to apex.

Legs. Protibia ( Fig. 284 ) triangular, broad at apex; two curved spines at apex of outer margin; apical one-half of inner margin with fine dense spines. Mesotibia ( Fig. 285 ) evenly widened to apex; with strong spines on outer margin and apically; inner margin convex. Male metatibia ( Fig. 386 ) narrow in basal one-half; widened in apical onehalf; curved; unmodified in female. Metafemur ( Fig. 286 ) moderately broad in male, slender in female. Male protarsomeres ( Fig. 284 ) bearing elongate setae laterally and thin, colorless, transverse phanerae ventrally; protarsomere 1 elongate. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 291 ) carinate, with a median tooth; excavation behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 287, 288 ) elongate, angulate at basal one-third and before apex; broad, narrowing and flattening before rounded, weakly lobed apex. Width of apex variable ( Fig. 289 ). Inverted internal sac ( Fig. 288 ) with elongate cluster of small spines medially and a complex sclerotized structure basally. Parameres ( Figs. 287, 288 ) narrow, about two-thirds length of median lobe; each paramere with one apical and one sub-apical seta. Spermatheca. Tubular ( Fig. 290 ), curved, sharply angulate medially.
