Plocamocera jayhawkalis , new species Figure 212 ; map 8

HOLOTYPE: Sex unknown. Suriname: Saramacca: west Suriname Road , 178 km WSW Zanderij Airport, 25 m, 4 ° 59 ̍ 6 ̎ N, 56 ° 18 ̍ 48 ̎ W; 13 JUN 1999, Z. H. Falin; SUR 1 F 99 070; Ex: splintered tree trunk (pyrethrum fogging)( SEMC). (Specimen point mounted, antenna affixed to paper point; support card, white; SEMC repository label, white, machine printed; locality label, white, machine printed; electronic repository label, white, plastic; holotype label, red, machine printed.)

PARATYPES: One specimen examined.

DIAGNOSIS: These beetles are most closely allied to the members of P. pupula , n. sp. from which they may be distinguished by the shape of the eighth antennomere. In P. jayhawkalis , n.sp., the outer angle of the anterodistal margin of the eighth antennomere is blunt (fig. 212). In P. pupula , n. sp., the outer angle of the anterodistal margin of the eighth antennomere is distinctly acute (fig. 195). Also, in P. jayhawkalis , n. sp., the ninth antennomere is abruptly constricted at its posterior limits, whereas in P. pupula , n. sp., the apical constriction is gradual.

DESCRIPTION: Size: Length 7.0 mm; width 3.0 mm. Integument: Predominantly castaneous; anterior disc of pro­mesotibiae infuscated, posterior disc metatibiae infuscated near femoral apex; elytra variegated, with two dark transverse bands near apex. Head: Antennal club as in figure 212. Thorax: Pronotal anterior margin broadly projected at middle; elytral epipleural margin with five conspicuous trichobothria; protibial anterior margin with five spines. Abdomen: The abdomen of the holotype specimen is missing.

VARIATION: Not studied.

NATURAL HISTORY: The holotype specimen was collected from Surinam, during June, at 25 m, by fogging, a splintered tree trunk with pyrethrum.

DISTRIBUTION (map 6): This species is known only from Surinam.

ETYMOLOGY: The specific epithet is a compound noun in apposition. It stems from the mascot name of Kansas University (‘‘jayhawks’’) and the Latin possessive suffix­ alis. The author, a Kansas State ‘‘wildcat’’, wishes to extend his appreciation, and a tribute, to Kansas University for providing Kansas State University with many years of collegial athletic competition.

Plocamocera specula (Klug)

Figures 178, 180

Enoplium speculum Klug, 1842: 372 . Lectotype male. Here designated. Brazil (ZMNB). (Specimen point mounted; support card, white, sex label affixed to support card; type label, orange, machine printed; ZMNB historical collection label; specimen number (58854) label, white, machine printed; identification/locality label, turquoise, cursive; ZMHB repository label; lectotype label, red, machine printed; identification label, white machine printed; plastic vial with abdomen and aedeagus.)

PARATYPES: None.

DIAGNOSIS: These beetles may be conveniently distinguished from superficially similar specimens of P. quadrula Opitz by the more slender form of the eighth antennomere (compare figs. 146, 180), and the more rectangular elytra (compare figs. 178, 179).

DESCRIPTION: Size: Length 6.8 mm; width 2.0 mm. Integument: Cranium piceous; pronotum dark castaneous; elytra variegated, with testaceous humeral macula, with three irregularly shaped aggregates of white setae; legs dark testaceous. Head: Antennomere eight as in figure 180. Thorax: Pronotal anterior margin moderately projected at middle; elytral epipleural trichobothria missing; protibiae missing. Abdomen: Male pygidium evenly arcuate in posterior margin; aedeagus broad lanceolate.

VARIATION: Not observed.

NATURAL HISTORY: No information available.

DISTRIBUTION: This holotype specimen was collected in Brazil.

Plocamocera baria , new species

Figures 147, 191 ; map 6

HOLOTYPE: Female. Venezuela: Amazonas: Rio Negro, Rio Baria , 0 ° 55 ̍ N, 66 ° 10 ̍ W, 140 m, 4–11–84, L. J. Joly, A. Chacon ( IZAV). (Specimen point mounted, sex label affixed to paper point, white, machine printed; support card, white; locality label, white, machine printed; coordinates label, white, machine printed; collectors label, white, machine printed; ownership label, green, machine printed; IZAV repository label, white, machine printed; holotype label, red, machine printed.)

PARATYPES: None.

DIAGNOSIS: The deeply concave distal margin of antennomeres 8 and 9 will distinguish the members of this species from those of the superficially similar specimens of P. confrater Kuwert.

DESCRIPTION: Size: Length 5.5 mm; width 2.0 mm. Integument: Cranium predominantly castaneous, frons infuscated; pronotum predominantly castaneous, anterior region of disc infuscated; elytra variegated, predominantly piceous, posthumeral flavotestaceous tripartite macula well developed, disc with short oblique flavotestaceous macula at middle, patches of pale setae extended to epipleural margin; legs bicolorous, pro–mesofemora piceous ventrally, flavotestaceous dorsally, metafemur flavotestaceous in basal half, piceous in distal half; tibia and tarsus piceous. Head: Antennal club as in figure 147. Thorax: Pronotal anterior margin moderately projected at middle; discal swelling prominent; elytral epipleural margin with five conspicuous trichobothria; protibial anterior margin with six spines. Abdomen: Female pygidium trigonal­scutiform.

VARIATION: Not observed.

NATURAL HISTORY: The available specimens were collected from southern Venezuela during February, at 140 m.

DISTRIBUTION (map 6): Southern Venezuela.

ETYMOLOGY: The trivial name constitutes a noun in apposition and refers to the type locality.

Plocamocera aura, new species Figures 161, 218 ; map 7 HOLOTYPE: Female. Bolivia: La Paz: Tumupasa, XII, Mulford Biological Explora­

tions, 1921–1922, W. M. Mann (USNM). (Specimens point mounted, antenna and sex label affixed to paper point, white, machine printed; support card, white; locality label, white, machine printed, expedition label, white, machine printed; USNM repository label, white, machine printed; holotype label, red, machine and hand printed.)

PARATYPES: None.

DIAGNOSIS: Specimens of this species may be distinguished from other members of the confrater group by the following combination of characteristics: interstitial spaces of elytral disc shiny, eighth antennomere only feebly narrowed distally, and tenth antennomere only slightly longer than antennomere nine.

DESCRIPTION: Size: Length 6.1 mm; width 2.1 mm. Integument: Cranium predominantly piceous, borders castaneous; pronotum predominantly piceous, borders castaneous; elytra variegated, flavotestaceous tripartite humeral macula well developed, mid­discal macula obscure, with three irregular patches of white setae, remainder of disc vested with admixture of piceous and golden setae, latter particularly abundant along sutural margin, legs bicolorous, pro­ mesofemora predominantly piceous, metafemora flavotestaceous in proximal half, piceous in remainder, tibia and tarsus castaneous. Head: Antennal club as in figure 161. Thorax: Pronotal anterior margin prominently projected at middle, discal swelling shallow; elytral epipleural margin with five conspicuous trichobothria; protibial anterior margin with four spines. Abdomen: Female pygidium broad­scutiform.

VARIATION: One specimen examined.

NATURAL HISTORY: The only available specimen was collected from Bolivia, in December.

DISTRIBUTION (map 7): Known only from the type locality.

ETYMOLOGY: The trivial name aura (glow) is a Latin adjective. I relate the name to the bright reflection from the interstitial spaces of the elytra.
