Treatment

Plocamocera quadrula , new species Figures 146, 188 View Figs , 179 View Figs ; map 7

HOLOTYPE: Male. Brazil: Matto Grosso : Sinop, X1995, M. Alvarenga ( AMNH). (Specimen point mounted, antenna and machine printed sex label affixed to paper point, white; locality label, white, hand printed; AMNH repository label, white machine printed; holotype label, red, machine printed; plastic vial with abdomen.)

PARATYPES: None.

DIAGNOSIS: Along with P. pupula , P. quadrula is the only other known species of the confrater group whose specimens do not have the distal narrowing of antennomere eight. Specimens of P. quadrula do not have the distal margin of antennomere eight feebly concave (fig. 146), which is the case in P. pupula specimens (fig. 145). Also, in P. pupula specimens the tenth antennomere is nearly twice as long as antennomere nine.

DESCRIPTION: Size: Length 5.7 mm; width 2.0 mm. Integument: Predominantly castaneous, frons feebly infuscated; pronotum predominantly castaneous, disc infuscated; elytra variegated, with flavotestaceous humeral macula oblique, with three irregular aggregates of white setae, golden setae abundant along sutural margin and in piceous regions of disc; legs flavotestaceous, metafemora faintly infuscated on inner distal surface. Head: Antennal club as in figure 146. Thorax: Anterior margin of pronotum boldly projected at middle; discal swellings prominent; elytral epipleural margin with five conspicuous trichobothria; protibial anterior margin with five spines, the second and third contiguous. Abdomen: Male pygidium broadscutiform; aedeagus lost.

VARIATION: One specimen studied.

NATURAL HISTORY: The holotype was collected in October.

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

ETYMOLOGY: The specific epithet quadrula is a Latin noun derived from quadrus (square). I refer to the rectangulate shape of the eighth antennal article.
