Plocamocera sericellopsis , new species Figures 157, 174 ; map 7

HOLOTYPE: Male. Brazil: Rondonia: 62 km SE Ariquenes , 5–6 Nov. 1996, W. J. Hanson ( MZSP). (Specimen point mounted, sex label affixed to paper point, white, machine print­ ed; support card, white; locality label, white, machine printed; MZSP repository label, white, machine printed; holotype label, red, machine printed; plastic vial with aedeagus.)

PARATYPES: None.

DIAGNOSIS: Specimens of this species resemble very closely members of P. sericella . However, P. sericellopsis specimens differ by having only three spines on the protibia, the male pygidium is emarginate, and the aedeagus is shorter and more stout.

DESCRIPTION: Size: Length 5.0 mm; width 1.5 mm. Integument: Cranium predominantly piceous, castaneous near eyes; pronotum castaneous near margins, disc piceous; elytra variegated, anterior third and postmedial region pale, remainder piceous, light setae concentrated in anterior third; legs predominantly flavotestaceous, femora feebly infuscated. Head: Antennal club as in figure 157. Thorax: Pronotal anterior margin moderately projected at middle; disc swellings shallow, pronotal arch subscabrous; no conspicuous trichobothria on the elytral epipleural margin were found; protibial anterior margin with five spines; number of elytral trichobothria not discernible on holotype specimen. Abdomen: Male pygidium broad­scutiform, emarginate; aedeagus as in figure 174.

VARIATION: Not observed.

NATURAL HISTORY: The only available specimen was collected from the type local­ ity, in November, with a Malaise trap perched over recently felled tree trunks.

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

ETYMOLOGY: The specific epithet stems from the Latin trivial name sericella and the Latin suffix ­ opsis (likeness). I refer to the superficial similarities between the members of this species and those of P. sericella Spinola.
