Beardius sp. 2   Trivinho-Strixino & Strixino (1995: 79).

Material examined. Type material, as in Trivinho-Strixino & Strixino (2000). Additional material: Brazil, Acre State: Mâncio Lima, Serra do Divisor National Park, Pé da Serra , Igarapé Amor , 1 male, 18.iii.2006, light trap, A.R. Calor   . Bahia State: Barreiras   , Rio de Janeiro, Cachoeira Acaba-Vidas, S11°53'40" W45°36'06", 1 male, 14.x.2008, light trap, A.R. Calor et al. Camacan, Serra Bonita Reserve , córrego 2, S15°23'10'' W39°34'03'', 1 male, 01.viii.2008, light trap, A.R. Calor et al GoogleMaps   . Mato Grosso State: Ribeirão Cascalheira, Estrada para Fazenda Manaus , Represa 1 km após 2º afluente do Ribeirão Bonito , S12°55'36" W51°53'28", 1 male, 08.x.2007, light trap, L.C. Pinho et al GoogleMaps   . São Paulo State: Jundiaí, Serra do   Japi State Park, Trilha para Cachoeira Paraíso , 2 males, 29.viii.2007, light trap, L.S. Lecci et al   .

Diagnostic characters. The species belong in the xylophilus   group. The male can be separated from all other members of the genus by the combination of the following characters: acrostichals present; anal point long, bluntly triangular, fully covered with microtrichia; and basal projection of inferior volsella long, digitiform, bearing long lamellae reaching apex of inferior volsella. The larvae by the combination of: antenna with 6 segments; antennal blade longer than flagellum; and median ends of ventromental plates pointing medially.

Description. The species was described in detail by Trivinho-Strixino & Strixino (2000). The structure considered as “median volsella” by Trivinho-Strixino & Strixino (2000) must be regarded as a basal, digitiform projection of the inferior volsella, bearing long lamellae. Median volsella is absent. The projection of the inferior volsella is longer than figured by Trivinho-Strixino & Strixino (2000) and the base of inferior volsella has microtrichia ( Figs 150–151 View FIGURES 150–151 ).

Distribution. The species is collected in the Acre, Bahia, Mato Grosso, and São Paulo states in Brazil.
