Paratypes
deposited in
RTPC
and
JEWC
.
Male
. Form elongate, slender, subcylindrical.
Integument
black to piceous, ventral aspect, legs and antennae moderately to densely clothed with short, fine, grayish recumbent pubescence, pronotum and elytra striped with slightly coarser recumbent pubescence.
Head
with front convex; median line moderately impressed, ending caudally at the base of the antennal tubercles in a flattened diamond to triangularly shaped denuded area; frons, area behind and between the eyes, tubercles, dorsallateral areas of the gena, and basal margins covered with hoary pubescence; upper lobes of the eyes separated by 3/5 distance between the tubercle apices, lower lobes elongateovate, approximately the height of the gena directly below them.
Antennae
slender, surpassing elytra by 5–6 segments, moderately clothed with short, hoary pubescence, pubescence becoming longer and denser on distal segments, scape and second segment black, segments 3–6 dark reddish, annulate at apex, remaining segments black, nonannulate, third segment onethird longer than scape, fourth onesixth longer than scape, fifth subequal to scape, sixth and seventh nearly equal in length, shorter than fifth, remaining segments gradually decreasing in length, eleventh the shortest; scape elongate, distinctly surpassing pronotal tubercles, noncarinate, cylindrical, widest near apices, slightly impressed above on distal onethird to onefifth, below more deeply impressed on distal onefourth before apical process; apical process elongated, rounded in front, excavated behind, acutely rounded at apices, slightly retroarcuate.
Pronotum
cylindrical, width across tubercles equal to dorsal length, distinctly narrowed behind lateral tubercles, narrowly impressed behind apical margin, moderately punctate above and on sides, punctures separated by 1–3 times their diameter, smaller than those at base of elytra; dorsal and lateral hoary pubescence creating a vittate pattern, medially a narrow band of hoary pubescence is bordered by slightly wider black integumental bands; integumental bands sparsely clothed with minute, golden pubescence which partially obscures the surface, bordered laterally by a dense band of gray pubescence near base of lateral tubercles, remaining lateral area black; sides armed with moderately small, acute tubercles at basal third, tubercles slightly oblique and retrorse.
Scutellum
small, black, as broad as long, narrowly rounded, impunctate, sparsely clothed with minute, gray pubescence.
Elytra
together slightly less than three times as long as wide at humeri, gradually narrowed apically; covered with hoary pubescence alternating with integumental stripes creating vittae; suture narrowly black, each elytron with two, nearly parallel, elongate, black vittae beginning near the base and ending at apical sixth to seventh, converging near apices, sides with a broader linear black vitta of similar length, lateral margins and remain der of elytra covered with dense gray pubescence; each elytron with three to four rows of long, erect, slightly backward projecting, black, setae; elytra moderately punctate, punctures coarser at base, progressively smaller distally with apical fourth impunctate, black integumental stripes at sides coarsely punctate for most of their length; apices shallowly emarginate, lateral margins slightly produced.
Underside
densely pubescent except for the metepisternum; prosternal process at narrowest point onefifth as wide as procoxal cavities, procoxal cavities closed behind; mesosternal process simple, 23 times as wide as prosternal process.
Legs
elongate, moderately clavate; finely pubescent, bearing stout, golden hairs on apical onethird of tibiae.
Abdomen
densely pubescent, completely obscuring surface; terminal segment subtruncate, two times as broad as long with apical margin shallowly notched. Length
7.5–8.5 mm
, width
1.8–2.4 mm
.
Female
. Form similar to male; antennae surpassing elytral apices by 4–5 segments; abdomen with terminal segment 1.5 times as broad as long, apical margin slightly curved to straight. Length
8.2 mm
, width
2.3 mm
.
Remarks: This distinctive species is easily recognized by the narrow form and vittate pattern of the pronotum and elytra and the abundance of long, erect hairs over the elytra. All specimens were taken beating large, herbaceous plants growing along the roadside at an altitude above
7000 feet
. In the area of the
type
locality, Highway 134 is a steep winding road with numerous switchbacks. A somewhat unique moist habitat is created wherever these switchbacks are deeply set into the mountain. These areas catch and hold much of the rainfall runoff from the above adjacent slopes and support host plant abundance.
Etymology: This species is named after Robert H. Turnbow, Jr., tireless collector and ardent
Coleoptera
student who discovered part of the
type
series.
