Dallasiellus (Dallasiellus) levipennis (Signoret)

( Figs. 3F , 5 )

Geotomus levipennis Signoret, 1883: 35 .

Geocnethus prosternalis Horváth, 1919: 246, syn. by Froeschner, 1960. Dallasiellus (Dallasiellus) levipennis: Froeschner, 1960: 609 .

Material examined: 1 specimen, PA, Mocajuba , Mangabeira, 1953, Rego col., MNRJ; 1♀, Mocajuba , Mangabeira, Feb-1953, O.M. Rego col., MCNZ ; 1 specimen, AM, Manaus, Aug-1955, Elias col., MNRJ ; 1♂, ES, Santa Teresa, Parque Municipal São Lourenço , 15-Mar-2008, Carvalho col., MNRJ ; 1♀, RJ, Jacarepaguá, "D. Federal", 12-Mar-1952, O.M. Rego col., MCNZ ; 2 specimens, Rio de Janeiro, Corcovado, 25-Nov-1952, Zajciw col., MNRJ .

Distribution: Panama, Venezuela, Ecuador, Brazil (PA new rec., AM, MT, MG, ES new rec., RJ new rec., SP). Remarks: According to Froeschner (1960) this species shows important morphological variations on its characteristics; however the body length (9.6–12 mm), the mesopleural evaporatorium not interrupted by a polished band (pseudoperitreme) and the prosternal carinae higher than labial II may separate it of the remaining species of the subgenus. First record for SP in Brazil in Grazia & Schwertner (2011).
