DESCRIPTION OF PLOCAMOCERA SPECIES

MANAUSENSIS GROUP Plocamocera salasis , new species Figures 139, 171 , 186 ; map 6

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

PARATYPES: Four specimens from the same locality as the holotype ( CMNH, 1; WOPC, 3) .

DIAGNOSIS: Within the manausensis group only members of this species have the cranium bicolorous. The periphery of the cranium is castaneous, the remainder piceous.

DESCRIPTION: Size: Length 3.4–3.8 mm; width 1.1–1.3 mm. Integument: Cranium bicolorous, peripheral areas castaneous, remain­ der piceous; pronotum bicolorous, disc piceous, peripheral areas castaneous; elytra variegated, flavous humeral macula bifurcated posteriorly, postmedial flavous macula fasciate, three irregular aggregates of white setae, piceous regions with dark setae; legs flavous. Head: Antenna as in figure 139. Thorax: Pronotal anterior margin moderately projected at middle; discal swellings prominent; elytral epipleural margin with three conspicuous trichobothria; protibial anterior margin with three spines. Abdomen: Male and female pygidium broad­scutiform, truncate (as in fig. 97); aedeagus (fig. 171) lanceolate.

VARIATION: The castaneous portions of the cranium may be reduced to narrow peripheral regions.

NATURAL HISTORY: The available specimens were collected from the Amazon Basin during December, on felled tree trunks of Manilkara , at an altitude of 100 m.

DISTRIBUTION (map 6): Known only from the type locality.

ETYMOLOGY: The trivial name salasis is derived from the Latin salio (leap). I refer the specific epithet to the peculiar jumping behavior of these beetles.

Plocamocera manausensis , new species Figures 45 , 62, 63, 80, 94, 107, 115, 140, 183; map 6

HOLOTYPE: Male. Brazil: Amazonas : Manaus, 1 km W Taruma Falls, 100 m, 19­I­ 1981, primary forest, on bark, day, G. Ekis (now W. Opitz) ( MZSP). (Specimen point mounted, sex label affixed to paper point, white, cursive; support card, white; locality label, white, cursive; collector label, white, cursive; natural history label, white, cursive; holotype label, red, cursive; plastic vial with aedeagus.)

PARATYPES: One hundred seventy specimens from the same locality as the holotype ( AMNH, 2; BMNH, 1; CASC, 1; CMNC, 1; CMNH, 1; CNCI, 1; CSUC, 1; CUIC, 1; DEIC, 1; EMEC, 1; EMUS, 1; FMNH, 1; FSCA, 1; IMLA, 1; INBC, 1; INHS, 1; INSB, 1; IZAV, 1; JEWC, 1; JNRC, 1; LACM, 1; MCZC, 1; MLPA, 1; MMEC, 1; MNHN, 1; MRSN, 1; MSUC, 1; MZSP, 1; OSEC, 1; OSUC, 1; OSUO, 1; PMNH, 1; PURC, 1; QCAZ, 1; RFMC, 1; RHTC, 1; SEAN, 1; SEMC, 1; TAMU, 1; TUMC, 1; UCDC, 1; UMMZ, 1; UMRM, 1; UMSP, 1; USNM, 1; WFBC, 1; WFBM, 1; WOPC, 117; WSUC, 1; ZMAN, 1; ZMHB, 1). Brazil: Rondonia: 62 km SW Ariquemes, nr. Fzda. Rancho Grande, 10­17­V­1995, K. Vulinec, blacklight trap ( FSCA, 1) .

DIAGNOSIS: The members of this species can be conveniently distinguished from the members of other P. manausensis species by the extraordinary slender condition of the antennal club (fig. 45).

DESCRIPTION: Size: Length 2.8–3.5 mm; width 1.0–1.2 mm. Integument: Cranium black; pronotum predominantly piceous, periphery castaneous; elytra variegated (fig. 62), flavous posthumeral macula bifurcated posteriorly, postmedial flavous macula fasciate, apex flavous, flavous portions of disc densely matted with yellow setae, piceous portions of disc vested with dark setae; legs flavous. Head: Antenna as in figure 45. Thorax: Pronotal anterior margin moderately projected at middle; discal swellings not very prominent; elytral epipleural margin with three conspicuous trichobothria (fig. 63); protibial anterior margin with five spines (fig. 80). Abdomen: Male pygidium broad­scuti­ form, somewhat truncate (fig. 94), female pygidium broad­scutiform; aedeagus lanceolate (fig. 115); male internal reproductive organs as in figure 107.

VARIATION: Except for the slight tone variation of elytral color, the available specimens are quite homogenous.

NATURAL HISTORY: These beetles were collected from the environs of Manaus, Brazil, in January, on bark of Manilkara , during day and night.

DISTRIBUTION (map 6): Known only form the type locality.

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