Plocamocera taruma , new species Figures 162, 173 , 195 ; map 7

HOLOTYPE: Male. Brazil: Amazonas: Manaus , 1 km W. Taruma Falls, 19­I­1981, Weston Opitz ( MZSP). (Specimen point mount­ ed; antenna, pygidium, and machine printed sex label affixed to paper point; support card, white; locality label, white, machine printed; natural history label, white, hand printed; MZSP repository label, white, machine print­ ed; holotype label, red, machine printed; plastic vial with aedeagus.)

PARATYPES: Four specimens, three from the same locality as the holotype ( WOPC, 1). Brazil: Amazons: Paraque, 30 km E of Manaus, Amazon River, 34 km, 17­II­1981, Chen­wen Young ( CMNH, 1).

DIAGNOSIS: This species belongs to the subgroup of P. confrater in which specimens have the pronotum predominantly castaneous and only faintly infuscated. Within this subgroup, P. taruma specimens most closely approximate those of P. confrater , from which they are distinguished by the proportionally longer 10th antennal article (compare figs. 152, 162).

DESCRIPTION: Size: Length 5.0–6.5 mm; width 2.1–3.0 mm. Integument: Cranium predominantly castaneous, frons and vertex narrowly piceous; pronotum predominantly dark­castaneous, disc faintly piceous; elytra variegated, with flavotestaceous humeral macula that divides posteriorly, postmedial fascia indistinct, more vertical than transverse; three irregular aggregates of white setae, golden setae prominent only along sutural margin; disc also with copious vestiture of dark setae primarily on piceous regions; legs bicolorous; pro­mesofemora infuscated on anterior fascies, remainder flavotestaceous, metafemur flavotestaceous in basal half, piceous in remainder, tibia, and tarsus brunneus. Head: Antennal club as in figure 162. Thorax: Pronotal anterior margin prominently projecting at middle, disc feebly tumescent in front of middle; pronotal arch fee­ bly scabrose; elytral epipleural margin with five conspicuous trichobothria; protibial anterior margin with four spines. Abdomen: Male pygidium broad­scutiform, female pygidium trigonal­scutiform; pygidia with two discal and six marginal stout setae; aedeagus elongated, not broadened at base of tegmen (fig. 173).

VARIATION: The intensity of the cranial and pronotal infuscation varies.

NATURAL HISTORY: The three specimens from Taruma Falls were collected in January on freshly felled trunks of Manilkara , a genus of hardwood prominent in riverside habitats of the Amazonian Basin.

DISTRIBUTION (map 7): Known only from the Amazonian environs near Manaus and Matto Grosso highlands of Brazil.

ETYMOLOGY: The specific epithet taruma constitutes a noun in apposition and refers to the type locality.

NEW SYNONYMY. P. impressicolis Pic falls within the variation range of this species. Corporaal, 1950: 255. Opitz, 1997: 70–71.

DIAGNOSIS: The following combination of characteristics distinguishes the members of this species from congeners: Eighth antennomere subquadrate (fig. 42), tenth antennomere only slightly longer than antennomere 9; male pygidium (fig. 90) feebly emarginate at distal margin, female pygidium (fig. 91) trigonal, and aedeagus (fig. 112) sagittate.

DESCRIPTION: Size: Length 4.0–6.5 mm; width 1.5–2.8 mm. Integument: Cranium castaneous, vertex and frons linearly infuscated; pronotum castaneous; elytra (fig. 56) with two surface macula and three setal fasciae; legs bicolorous, promesofemora predominantly flavotestaceous, feebly infuscated on anterior surface, metafemur flavotestaceous in basal half, piceous in distal half; tibiae and tarsi piceous; abdomen predominantly flavotestaceous in females, brunneus in males. Head: Antenna as in figure 42. Thorax: Pronotal anterior margin projected at middle, discal swellings shallow; epipleural margin with five conspicuous and three inconspicuous trichobothria (fig. 57); protibia anterior margin with five spines (fig. 77). Abdomen: Male pygidium broad­scutiform (fig. 90), female pygidium trigonal scutiform (fig. 91): aedeagus saggitate. Internal Reproductive Organs: Male as in figure 102, female as in figure 103.

VARIATION: The pronotal disc is feebly infuscated in some specimens.

NATURAL HISTORY: Specimens of this species were collected from Guyana during March, Peru during April at about 160 m, Bolivia during December and August at 400 m, and throughout the year from Brazil.
