Two new fossil species of Bruchomyiinae (Diptera: Psychodidae), namely: Nemopalpus velteni Wagner, sp. n. (Burmese amber) and N. inexpectatus Wagner, sp. n. (Baltic amber), are described and figured, together with four extant species from the Neotropical Region: N. stuckenbergi Wagner, sp. n. (Chile), N. amazonensis Wagner & Stuckenberg, sp. n., N. similis Wagner & Stuckenberg, sp. n. (both Brazil) and N. cancer Wagner & Stuckenberg, sp. n. (Colombia). The terminalia of N. pilipes Tonnoir, 1922 are illustrated for the first time. Based on the shape of the male terminalia, N. stuckenbergi sp. n. is probably closely related to N. rondanica Quate & Alexander and to N. stenhygros Quate & Alexander, both of which occur in Brazil. Nemopalpus similis sp. n. (Brazil), N. pilipes Tonnoir (Paraguay), N. dampfianus Alexander (Mesoamerica) and N. capixaba Biral Dos Santos, Falqueto & Alexander (Brazil) form a distinct species-group of their own. Nemopalpus amazonensis sp. n. (Brazil) and N. rondanica Quate & Alexander (Brazil) are closely related, as are N. cancer sp. n. and N. phoenimimos Quate & Alexander, both from Colombia. The presence or absence of tergal extensions and ornamental setulae on various segments are here regarded as unreliable characters to assess relationships among Neotropical Nemopalpus. The internal male and female terminalia of Bruchomyiinae provide more-useful apomorphic features and it is here postulated that the Phlebotominae are probably phylogenetically older than Bruchomyiinae.
