Holotype:

Brazil: (MNHNP: ADP 058647, male).

Derivation of specific epithet.

The epithet " pusilla " is a Latin adjective meaning very little, small, pretty. Although this species resembles Agra pusilla it is "not" that species.

Proposed English vernacular name.

Brazilian Elegant Canopy Beetle.

Diagnosis.

With the attributes of the genus and species-group as described above and frons laterally multicarinate; elytra with interneurs composed of double rows (in part) of coarse irregularly shaped punctures, apex moderately lobed medially.

Description.

( Fig. 7 ). Size: Very small, ABL = 7.74 mm, SBL = 6.58 mm, TW = 1.88 mm. Color: Piceous, antennae and legs bicolored, scape and basal 5/6th of femur testaceous; antennal flagellum and mouthparts piceous. Luster: Head and abdomen shiny, elytral disc somewhat matte. Head: Labrum moderately elongate and truncate apically, slightly emarginate medially. Frons medially raised and smooth, laterally depressed, multicarinate. Gena rounded in female to constricted neck. Genae and with occiput sparse and moderately coarse punctures, some of which likely setiferous in undamaged specimens (no setae present in holotype), and with two larger punctures,. Prothorax: Slightly broader in basal third, constricted, and flared basally; surface densely punctate, laterally and ventrally setiferous. Pterothorax: Elytron markedly convex, intervals not costate, interneurs of double rows (in part) of somewhat irregularly shaped punctures, apex truncate, moderately lobate, apical dentation asymmetric, lateral tooth small, acute, sutural apex slightly produced, rounded. Metasternum sparsely setiferous in both females. Legs: Legs normal. Abdomen: Abdominal sterna III to VII of female moderately and bilaterally setiferous; sternum VII of females barely emarginate, corners rounded. Male genitalia: Unknown. Female ovipositor: Stylomere 2 ( Fig. 7 ).

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 notpusilla have no recorded information.

Other specimens examined.

None.
