Cavichioli and Chiamolera (1999) considered the habitus of D. basseti (Fig. 1A) similar to that of D. pauperata (Fig. 1H), whereas they regarded the male terminalia similar to those of D. isabellina, mainly due to the shape of the aedeagus (Figs 2E, 5E). However, D. basseti can be easily distinguished from these two species by the paraphyses (Fig. 2F, G) with the rami fused to each other along their basal halves, each one bifurcate at apex.

Dasmeusa dinizi sp. nov. (Fig. 1B) is similar to D. oriximina sp. nov. (Fig. 1G). These species share many similarities in the male terminalia, especially in the aedeagus and paraphyses. However, D. dinizi can be recognized by the two pairs of small processes on the paraphyses stalk (Fig. 3G), one located dorsally at the base of the apical third and another ventrally at the apex.

As mentioned in the key, D. falcifera sp. nov. (Fig. 1C) shares with D. rafaeli sp. nov. (Fig. 1I) the presence of a distinct red spot at the second apical cell of the forewing. The former can be readily distinguished from the latter, as well as from the remaining known species of the genus, by paraphyses with the apical portion of the rami, in lateral view, directed dorsally (Fig. 4G) and pygofer well produced posteriorly and with the posterior margin narrowly rounded (Fig. 4B).

♂ paratype 8.4 mm; ♂ 7.8 mm. Head (Figs 1E, 5A): in dorsal view, strongly produced anteriorly; median length of crown approximately 9/10 of interocular width and 5/10 of transocular width; anterior margin rounded; ocelli large, located approximately on imaginary line between anterior eye angles; surface of crown flat; antennal ledge, in dorsal view, slightly protuberant; in lateral view, with anterior margin convex.

Cavichioli and Chiamolera (1999) considered D. isabellina (Fig. 1E) similar to D. basseti (Fig. 1A) in the male terminalia, especially the aedeagus. These two species can be distinguished from each other by the shape of the apex of the paraphyses rami, which are bifurcated in D. basseti (Fig. 2F) and not bifurcated in D. isabellina (Fig. 5F). The dorsal region of the body (Fig. 1E) is somewhat more orange in D. isabellina than in other species of the genus.

♂♂ 9.2–9.6 mm (n = 3). Head (Figs 1F, 6A): in dorsal view, well produced anteriorly; median length of crown approximately 8/10 of interocular width and 5/10 of transocular width; anterior margin rounded; ocelli large, located approximately on imaginary line between anterior eye angles; surface of crown slightly concave; antennal ledge, in dorsal view, not protuberant.

According to Young (1977), the body of D. mendica (Fig. 1F) is slenderer and more delicate than that of D. pauperata (Fig. 1H). Dasmeusa mendica can be distinguished from D. pauperata, as well as from the remaining known species of the genus, by the short and somewhat sinuous aedeagus, bearing a pair of ventral, preapical sclerotized dentiform processes (Fig. 6E, F).

A Sternite VII, ventral view; B pygofer, lateral view; C valvifer I and valvula I, lateral view; D dorsal sculptured area; E apical portion; F valvula II, lateral view (schematic, see associated photos [G, H, I] for details of teeth and other structures); G basal teeth; H median teeth; I apical portion. DEN = denticle; DSA = dorsal sculptured area; DUC = duct; PPR = preapical prominence; RAM = ramus; TOO = tooth; VID = ventral interlocking device; VLI = valvifer I; VSA = ventral sculptured area.

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). The shape of paraphyses, with strongly divergent arms, is also unique (Fig. 8G–I).

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), 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) 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). 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.

The name flavescens was proposed by Metcalf (1955) as a replacement for lurida Signoret, 1853, which was preoccupied by lurida Germar, 1821.

♂ holotype 8.0 mm; ♂ paratypes 7.6–8.0 mm (n = 2). Male holotype. Head (Figs 1I, 12A): in dorsal view, well produced anteriorly; median length of crown approximately 8/10 of interocular width and 5/10 of transocular width; anterior margin rounded; ocelli large, located approximately on imaginary line between anterior eye angles; surface of crown convex; antennal ledge, in dorsal view, not protuberant. Thorax (Figs 1I, 12A) with pronotum, in dorsal view, with width slightly greater than transocular width of head; lateral margins slightly convergent anteriorly. Forewing with base of fourth apical cell approximately aligned with base of third.

Head, pronotum, mesonotum, and forewing pale yellow; second apical cell of forewing with distinct red spot.

Pygofer (Fig. 12B), in lateral view, with posterior margin broadly rounded; macrosetae distributed mostly on posterior half but some located more anteriorly. Subgenital plate (Fig. 12C), in ventral view, with basal half broad and distal half narrow; with elongate uniseriate macrosetae on basal half, microsetae distributed along outer lateral margin. Connective (Fig. 12E), in dorsal view, V-shaped; stalk carinate dorsally, much longer than one arm width. Style (Fig. 12D), in dorsal view, slender, elongate, not extending posteriorly beyond apex of connective; narrowed apically, apex obtuse. Aedeagus (Fig. 12F), in lateral view, falciform, with apical spiniform process directed posteroventrally; gonoduct distinct, gonopore located apically. Paraphyses slightly asymmetrical; elongate, extending posteriorly beyond subgenital plate apex; stalk shorter than rami; in dorsal view (Fig. 12G), rami slender, slightly divergent posteriorly; in lateral view (Fig. 12H), rami narrowing gradually towards apex.

The color pattern of D. rafaeli sp. nov. (Fig. 1I) is similar to that of D. falcifera sp. nov. (Fig. 1C) because both have a distinct small red spot at the second apical cell of the forewing. The aedeagus of D. falcifera bears a conspicuous dentiform process at the basal half of the ventral margin (Fig. 4E), a feature that is not present in D. rafaeli (Fig. 12F).
