Pinodytes idaho Peck & Cook , new species

( Figs. 15 , 136 , 153–159 )

Type material. Holotype: male ( WFBM). UNITED STATES. Idaho: Idaho Co., Slate Creek Campgrd., 10mi E Slate Creek, IV-28-1983, F.W. Merickel (B.F.) . Paratypes (2): same data as holotype ( WFBM) .

Material examined. We have examined 3 specimens.

Distribution. Specimens ( Fig. 136 ) are known only from Idaho County, in northern Idaho.

Diagnostic description. Total length 1.28–1.38 mm; greatest width 0.61–0.65 mm. Light reddish brown; elongate-oval in shape ( Fig. 15 ). Head. With scattered fine punctures, shining, microsculpture of sinuate lines on vertex. Antenna ( Fig. 153 ) with antennomere 2 longer than 3; antennomere 5 slightly larger than 4 and 6; antennomere 7 slightly longer but not wider than 8; antennomeres 9 and 10 each with a single sensory vesicle indicated apically by a protruding flange. Pronotum. With minute, widely spaced punctures, shining, with microsculpture of sinuate lines with cross-connections. Widest subbasally; sides rounded; apical margin weakly emarginate, basal margin straight; apical angles rounded, basal angles about right-angled. Elytra. With fine punctures in longitudinal rows, becoming obscure laterally and apically; punctures joined by fine transverse strioles. Barely wider than pronotum; widest subbasally, narrowing to apex. Legs. Protibia ( Fig. 154 ) slender; spinose apically; apical one-half of inner margin finely, densely spinose. Mesotibia ( Fig. 155 ) slender, straight, strongly spinose. Metatibia ( Fig. 156 ) slen- der, nearly straight; apical one-half spinose. Metafemur ( Fig. 156 ) slender. Male protarsomeres ( Fig. 154 ) not expanded, bearing elongate setae laterally and two rows of thin, colorless, transverse phanerae ventrally. Mesotarsomeres without phanerae. Venter. Mesoventrite ( Fig. 159 ) carinate, longitudinal carina with median tooth; not excavated behind transverse carina. Male genitalia. Median lobe of aedeagus ( Figs. 157–158 ) elongate, broad, with dorsoventrally flattened, lobed apex. Inverted internal sac ( Fig. 158 ) with two bands of elongate setae. Parameres ( Fig. 157, 158 ) broad with flattened apices; not reaching apex of median lobe; each bearing two setae before apex. Spermatheca. Elongate, cylindrical, curved.

Etymology. The name idaho , a noun in apposition, refers to the type locality of this species in the state of Idaho, USA.
