Bílý, Svatopluk & Brûlé, Stéphane, 2013, A study on the genus Agrilaxia of French Guiana (Coleoptera: Buprestidae: Anthaxiini), Acta Entomologica Musei Nationalis Pragae 53 (2), pp. 657-686 : 684

Agrilaxia (Agrilaxia) sp. A

( Figs 15 , 27 , 38 )

Specimens studied. FRENCH GUIANA: COMMUNITE DE ROURA: “Guyane Fr., 12.iv.2010, Mont. de Chevaux, Comm. de Roura, RN2 PK22, 75 m, 4°44′56′′N 52°26′28′′W, P.-H. Dalens leg.” (1 J, NMPC). COMMUNITE RE- GINA: “Guyane Fr., 12.ix.2010, Réserve Naturelle des Nouragues, Camp Inselberg, ex larva, Comm.Régina, 3°37′N 53°12′W, S. Brûlé, P.-H. Dalens & S. Fernandez leg.” (2 ♀♀, NMPC):.

The poorly preserved male without the head and all right legs and the two completely damaged females (one of them without the abdomen and all appendages, the second preserved only as elytra and thorax).

Small (4.8 mm), entirely black species with weak violet lustre ( Fig. 15 ) and dark green frons (♀).

Unfortunately these very destroyed specimens are not suitable for the description of a new species. It is also impossible to attribute this species to any species-group of the genus Agrilaxia . The very special form of prosternum with medial carina ( Fig. 27 ), very wide frons and vertex, the emarginate anal ventrite together with the very long hind tarsi, simple anal tergite and the small, narrow scutellum (resembling that of the following species) are very unusual within the genus. Aedeagus ( Fig. 38 ) short, spindle-shaped, median lobe pointed apically.
