Distribution.
Specimens (
Fig. 224
) are known only from Tuolumne County,
California
, on the western slope of the Sierra
Nevada
Mountains, in and near Yosemite National Park.
Diagnostic description
.
Total length
1.64 mm
; greatest width
0.88 mm
. Reddish brown; oval in shape (
Fig. 27
).
Head
. Finely, sparsely punctate; a pair of larger punctures on vertex; shining, with microsculpture of transverse lines on vertex. Eyes absent. Antenna (
Fig. 249
) with antennomeres 2 and 3 subequal in length, 2 wider than 3; antennomere 5 larger than 4 and 6; antennomere 7 longer but not wider than 8; antennomeres 9 and 10 each with a single sensory vesicle indicated apically by a protruding flange.
Pronotum
. With scattered fine punctures, a few larger punctures at base and apex; shining; completely covered with substriate microsculpture. Widest at base, sides slightly rounded and narrowing to apex; apical margin emarginate; basal margin broadly, weakly emarginate; apical angles rounded, basal angles more narrowly rounded.
Elytra
. Punctation fine, serially arranged but not impressed; punctures joined by fine transverse strioles. Joined elytra slightly wider than pronotum; widest at base; nearly parallel in basal one-half, narrowing to apex; weakly serrate laterally.
Legs
. Protibia (
Fig. 250
) slender; with spines apically and near base of outer margin; apical one-half of inner margin finely, densely spinose. Mesotibia (
Fig. 251
) slender, weakly curved; strongly spinose apically, on outer margin, and apical one-third of inner margin. Metatibia (
Fig. 252
) moderately elongate, curved in male, widened in apical three-fifths; spinose apically, two spines on ventral face; apical one-half of inner margin with widely spaced fine spines. Metafemur (
Fig. 252
) moderately slender. Male protarsomeres (
Fig. 250
) expanded, bearing elongate setae laterally and thin, broad, colorless phanerae ventrally. Mesotarsomeres without phanerae.
Venter
. Mesoventrite (
Fig. 256
) carinate; longitudinal carina depressed at middle; with toothlike expansion in anterior one-half; not excavated, but with a small depression behind transverse carina.
Male genitalia
. Median lobe of aedeagus (
Figs. 253, 254
) broad, with narrow, flattened apex. Inverted internal sac (
Fig. 254
) with cluster of spines. Parameres (
Figs. 253, 254
) elongate, broad, extending beyone apex of median lobe; with a small flange on inner margin before apex; each bearing two well separated setae before apex.
Spermatheca
. Elongate (
Fig. 255
), bulbous at apex.
