Pinodytes ovatus ( Hatch, 1957) , new combination

( Figs. 7 , 87–95 )

Catopocerus ovatus Hatch 1957: 21 .

Type material. Type male in USNM, seen. Type label data: 5 mi N Gold Beach, Curry County, Oregon ; 11.V.1955, J. Capizzi.

Additional material examined. We examined an additional 44 specimens (see Appendix).

Distribution. Specimens ( Fig. 87 ) are known only from Curry County, in southwestern Oregon.

Diagnosis. Total length 1.26–1.34 mm; greatest width 0.77–0.80 mm. Reddish brown; oval in shape ( Fig. 7 ).

Head. Finely, sparsely punctate, shining, with transverse substriate microsculpture on vertex. Eyes absent. Antenna ( Fig. 88 ) with antennomere 3 narrower than 2, 2 and 3 subequal in length; antennomere 5 larger than 4, longer than 6; antennomere 7 longer but not wider than 8; antennomeres 9 and 10 each with a sensory vesicle indicated apically by a protruding flange. Pronotum. Finely, sparsely punctate; with transverse, closely spaced substriate microsculpture. Widest at base, nearly as wide as elytra; sides rounded, converging to apex; apical margin weakly emarginate, basal margin nearly straight; apical angles broadly rounded, basal angles narrowly rounded. Elytra. Punctation fine, in obscure longitudinal rows, striae not impressed; with fine, rather widely spaced transverse strioles. Joined elytra broad, widest at basal one-fourth. Legs. Protibia ( Fig. 89 ) slender; apical two-thirds of outer margin and apical margin spinose; apical one-half of inner margin with fine, short spines. Mesotibia ( Fig. 90 ) slender; strongly spinose on outer margin and apically; an exceptionally elongate spine at middle of outer margin; smaller spines on apical one-third of inner margin. Metatibia ( Fig. 91 ) slender, nearly straight; with strong spines apically, smaller spines on outer and inner margins. Metafemur ( Fig. 91 ) slender. Male protarsomeres ( Fig. 89 ) feebly or not dilated, bearing elongate setae laterally and thin, broad, colorless phanerae ventrally. Mesotarsomeres without phanerae.

Venter. Mesoventrite ( Fig. 95 ) carinate; longitudinal carina with expansion in anterior one-half; not excavated behind transverse carina. Transverse carina on different plane than longitudinal carina. Male genitalia. Median lobe of aedeagus ( Figs. 92, 93 ) elongate, broad, narrowing strongly at apex. Inverted internal sac with paired large spines and clusters of small spines. Parameres ( Figs. 92, 93 ) moderately broad with flattened apices not surpassing apex of median lobe; each with two closely spaced elongate setae before apex. Spermatheca. Elongate ( Fig. 94 ), tubular, weakly curved.
