Agra perforata Liebke 1938: 60.

Holotype:

Brazil: Rio de Janeiro, Rio de Janeiro, 585m, 22.9517°S, 43.2116°W (WAR: ADP 060035, female).

Derivation of specific epithet.

The epithet " perforata " is a Latin adjective referring to the cribriform punctures of the elytral interneurs.

Proposed English vernacular name.

Perforated Elegant Canopy Beetle.

Diagnosis.

With the attributes of the genus and species-group as described above and frons laterally multicarinate; occiput coarsely punctate; all elytral interneurs throughout with double rows of cribriform punctures.

Description.

Size: Small, ABL = 8.22 mm, SBL = 6.58 mm, TW = 1.88 mm. Color: All black with mostly testaceous femur. Luster: Head slightly shiny, pronotum and elytra matte black. Head: Labrum moderately elongate and rounded apically. Frons medially raised and smooth, laterally depressed, moderately rugose. Gena markedly rounded to constricted neck in female. Genae and occiput with sparse and coarse punctures, some setiferous. Prothorax: Short, slightly broader medially, flared basally; surface with dense and coarse punctures, some setiferous; lateral elongate callous with single row of setiferous punctures along middle. Pterothorax: Elytron markedly convex, intervals slightly costate, interneurs of double rows of somewhat irregularly-shaped punctures, apex moderately oblique and lobed, apical dentation asymmetric, lateral tooth small, broad, obtuse, sutural apex not produced. Metasternum sparsely setiferous in females. Legs: Normal in female. Abdomen: Abdominal sterna III to VII of female moderately and bilaterally setiferous; sternum VII of female barely emargi nate, corners rounded. Male genitalia: Unknown. Female ovipositor: Stylomere 2 as in Agra notpusilla ( Fig. 7 ).

Dispersal potential.

These beetles are macropterous and are probably capable of flight; they are swift and agile runners.

Way of life.

Adults of other Agra species are found in the canopy of rainforest trees; known larvae of this genus ( Arndt et al. 2001) are found under the bark of these trees, however they must also roam on the surface, as they have been collected by insecticidal fogging techniques in the very early morning before first light. Members of Agra perforata occur at midland altitudes in the Mata Atlântica.

Other specimens examined.

None.
