Dasmeusa flavescens Metcalf, 1955: 264, new name for Tettigonia lurida Signoret, 1853: 662, which was preoccupied by T. lurida Germar, 1821: 70. Syn. nov.

Dasmeusa flavescens Note: Young (1977: 293) regarded D. flavescens as a valid species, but Stål (1869: 77) treated T. lurida Signoret as a synonym of T. pauperata (Fabricius).

Taxonomic notes.

Dasmeusa pauperata can be readily distinguished from the remaining known species of the genus by the aedeagus with a large ventral lobe and a dorsoapical digitiform projection (Fig. 8F View Figure 8 ). The shape of paraphyses, with strongly divergent arms, is also unique (Fig. 8G-I View Figure 8 ).

As mentioned above, Dasmeusa flavescens Metcalf, 1955 was proposed as a new name for Tettigonia lurida Signoret, 1853, which was preoccupied by T. lurida Germar, 1821. Young’s (1977) confirmation of Metcalf’s (1955) generic assignment was based on a study of the female lectotype of T. lurida (Fig. 10A-F View Figure 10 ), which is deposited in the Naturhistorisches Museum Wien. Young (1977) also suggested that D. flavescens , which was originally described from Brazil ( Young 1977; Zanol and de Menezes 1982; McKamey 2007) and subsequently recorded from Suriname ( Wilson et al. 2009), could be a junior synonym of D. pauperata (Fabricius, 1803). We have been able to study photographs of the T. lurida lectotype (Fig. 10A-F View Figure 10 ) and a female specimen from Pará State ( “Belém \ Pará - Brazil \ IX.1964 \ E. Dente" [MZSP]). In agreement with Young’s (1977) suggestion, it appears to us that D. flavescens is actually a junior synonym of D. pauperata .

Young (1977: 1105) treated Erythrogonia bicolor Metcalf, 1949 as incertae sedis because he did not find specimens that could be associated with this name. We have examined a photograph of the male holotype (body in dorsal view) of E. bicolor , from Guyana, which is deposited at the entomological collection of the North Carolina State University, Raleigh (Fig. 11A View Figure 11 ). The external form and coloration, as well as the illustrations of the male terminalia provided by Metcalf (1949), suggest that this species is also a junior synonym of D. pauperata .
