New records. The original description of D. tibialis (as Mesostenus tibialis Brullé ) recorded the species from Guaratuba, southern Paraná, Brazil. The description of Fenixia curta added new records to southern and southeastearn Brazil. This work adds new records to Espírito Santo, Brazil, as follows: Domingos Martins, Mata Pico do Eldorado (20º22'17''S 40º39'29''W) - 1 Ψ, 4 ď; Cariacica, Reserva Biológica de Duas Bocas, Pau Amarelo (Alto Alegre) 1 ď; Conceição do Castelo, Distrito Ribeirão do Meio, 1 Ψ, 1 ď. It adds also records for four localities at Rio Grande do Sul, Brazil, with one female specimen each: Arroio Grande (29º39'60"S 52º40'00"W), Morro Redondo (31º40'22"S 52º35'30"W), Pelotas (31º44'39"S 52º13'22"W) and Capão do Leão (31º48'16"S 52º24'13"W). Records of single female specimens were also found from Parque Nacional da Chapada dos Veadeiros, Goiás, Brazil (14º00'20"S 47º41'04"W); Coroico, Nor Yungas, Bolivia (16º11'22" S 67º43'11"W) and Dos de Mayo, Missiones, Argentina (27º02'00''S 54º39'00''W). Figure 6 shows two maps with all known distribution records for both species of Distictus . The records suggest that D. tibialis is more often found in highlands, and that it may also be more common than initially thought; Distictus was the third gabuniine genus in number of specimens among the examined material. They also indicate that the species is not endemic of the Brazilian Atlantic Forest, althought it appears to be most common in this biome.
