HOLOTYPE: ( FSCA). Bolivia: Santa Cruz,

3.7 km SSE Buenavista, Hotel Flora & fau­

na, 405 m, 5–15­XI­2001, 17 ° 29.949 ̍ S, 63 ° 33.152 ̍ W, M. C. Thomas & B. K. Dozier, tropical transition forest. (Specimen point mounted, sex label affixed to paper point, white, cursive; support card, white; locality label, white, machine printed; FSCA repository label, white, machine printed, holotype label, red, machine printed; plastic vial with abdomen and aedeagus.)

PARATYPES: Six specimens from the same locality as the holotype ( FSCA, 2; WOPC, 4) .

DIAGNOSIS: The members of this species may easily be confused with the superficially similar specimens of P. aura n. sp., also from Bolivia. However, the members of this species are distiguished from those of P. aura, n. sp. by the gritty property of the elytral interstitial spaces and by the subtle, but consistent, differences of antennomeres eight and nine (compare figs. 217–218). The anterodistal margin of the eighth antennomere is much less concave than it is in the holotype of P. aura n. sp. The distal, or apical, portion of antennomere nine is gradually less narrowed in P. buenavista , n. sp., than it is in specimens of P. aura, n. sp. (compare figs. 217–218).

DESCRIPTION: Size: Length 4.8–5.0 mm; width 8.0–2.2 mm. Integument: Cranium castaneous; pronotum castaneous, disc infuscated; remainder of thorax castaneous except promesofemora infuscated on anterior disc, metafemur black in distal half, tibiae variously infuscated; elytral color variegated, predominantly dark­cataneous, flavotestaceous trigonal posthumeral macula well developed. Head: Antenna as in figure 217. Thorax: Pronotal anterior margin notably projected at middle; elytral epipleural margin with five conspicuous trichobothria; protibial anterior margin with 3 spines. Abdomen: Male pygidium broad scutiform, female pygidium narrow scutiform; aedeagus (fig. 216) lanceolate, phallic struts particularly elongat­ ed.

VARIATION: The elytral disc is considerably more pale than it is in the other specimens. Otherwise, the available specimens are quite homogeneous.

NATURAL HISTORY: The available specimens were collected during November. In a tropical transition forest at 405 m.

DISTRIBUTION (map 8): This species is known only from the type locality.

ETYMOLOGY: The specific epithet is a noun in apposition. It is used as a tribute to the fine Bolivian people of Buena Vista.
