Neponymphes godoii Zamboni, 2001 (p. 134, figs A, B): Martins Neto (2005, p. 479); Popov & Bechly (2007, p. 320 and 593); Criscione & Grimaldi (2017, p. 1167); Moura-Júnior et al. (2018, p. 154).

Material. Neotype (here designated): MCT 6955 - I. Paraneotypes (here designated): MCT 6952 - I, MCT 6953 - I, MCT 6954 - I, SMNS 66563 View Materials . See full justification in material and methods.

Emended diagnosis. Belostomatini with total body length (adults) 10.35–12.40 mm; body approximately two times longer than wide. Compound eyes globular, with their lateral margins never flushing with lateral margins of pronotum and frons; interocular total length approximately two times longer than anteocular total length. Total length of pronotum 0.79–0.89 mm; posterior pronotal width approximately three times greater than length at median line. Lateral margins of abdomen apparently smooth, never interrupted at borders between segments. Nymph (probably fifth stadium) with total length of body 9.75 mm; wing pads visible, well developed, reaching second abdominal tergite (first visible).

Locality and horizon. Crato Formation, Ceará State, Brazil; upper Aptian (~114 Ma), Lower Cretaceous.

Description. Adult ( Figs 2–6 View FIGURE 2 View FIGURE 3 View FIGURE 4 View FIGURE 5 View FIGURE 6 , Tab. 1 View TABLE 1 ). Body preserved in dorsal view, except for MCT 6952 - I (ventral view); total length 10.35–12.40 mm, approximately two times longer than wide. Head ( Figs 2E View FIGURE 2 , 3B, C View FIGURE 3 , 4C, G View FIGURE 4 , 5B, C View FIGURE 5 , and 6B View FIGURE 6 ) 1.40 mm long and 2.51 mm wide. Compound eyes globular, wider than vertex, their diameter 1.00 mm, lateral margins never flushing with lateral margins of pronotum and frons. Interocular total length (0.85 mm) approximately two times longer than anteocular total length (0.41 mm).

Thorax. Pronotum ( Figs 2C View FIGURE 2 , 3B, C, E View FIGURE 3 , 4C, G View FIGURE 4 , 5B–D View FIGURE 5 , and 6D View FIGURE 6 ) transverse, 0.79–0.89 mm long and 3.18 mm wide; concave anteriorly and approximately straight posteriorly; posterior pronotal width approximately three times greater than length at median line. Mesonotum ( Figs 2C View FIGURE 2 , 3B, E View FIGURE 3 , 5C View FIGURE 5 , and 6D View FIGURE 6 ) 1.29 mm long and 3.95 mm wide; scutellum ( Figs 3B, E View FIGURE 3 , 5C View FIGURE 5 , and 6D View FIGURE 6 ) 0.89 mm long and 1.40 mm wide. Hemelytra ( Figs 5D–F, H View FIGURE 5 , and 6I, J View FIGURE 6 ) partially preserved; the following veins can be observed: R, M, Cu, and CuP+A; membrane with reticulation ( Fig. 5H View FIGURE 5 ). Fore legs ( Figs 2A View FIGURE 2 , 3A View FIGURE 3 , 4C, G View FIGURE 4 , 5B, C View FIGURE 5 , and 6B View FIGURE 6 ) raptorial, 4.15 mm long (MCT 6952 - I); femora and tibiae visible, former ones ( Fig. 2A View FIGURE 2 ) with sulcus. Middle legs ( Figs 2B View FIGURE 2 , 3D View FIGURE 3 , 4B, C View FIGURE 4 , 5G View FIGURE 5 , and 6C, K View FIGURE 6 ) approximately 6.2 mm long; tibiae and tarsi with fringe of setae ventrally; tarsal claws visible. Hind legs ( Figs 2D View FIGURE 2 , 3A, F View FIGURE 3 , 4B, D, F View FIGURE 4 , and 6F, H View FIGURE 6 ) 10.66 mm (MCT 6952 - I) to 10.85 mm (MCT 6952 - I) long; tibiae and tarsi with fringe of setae ventrally; tarsal claws visible. Tarsus of all legs apparently dimerous ( Figs 3D, F View FIGURE 3 , 5G View FIGURE 5 , 6H View FIGURE 6 , and 7H View FIGURE 7 ).

Abdomen ( Figs 3G, H View FIGURE 3 , 4E, H View FIGURE 4 , 5E, F, H View FIGURE 5 , and 6G, I View FIGURE 6 ) broad, 6.35 mm long and 5.25 mm wide; sternites not subdivided by a suture-like fold. Lateral margins apparently smooth, never interrupted at borders between segments. Distal portion with distinct lateral setae ( Fig. 3H View FIGURE 3 ). Terminalia partially preserved ( Fig. 3G View FIGURE 3 ); it is not possible to determine the sex. Short respiratory siphon located at abdominal apex ( Fig. 4E, H View FIGURE 4 ).

Nymph ( Fig. 7 View FIGURE 7 , Tab. 1 View TABLE 1 ). Probably fifth stadium. Body preserved in dorsal view, oval ( Fig. 7A View FIGURE 7 ), 9.75 mm long, narrowed at anterior and posterior ends. Head ( Fig. 7C View FIGURE 7 ) triangular; compound eyes wide, salient, globular. Thorax with pronotum ( Fig. 7A, C View FIGURE 7 ) trapezoidal, wider than head, 0.68 mm long and 3.83 mm wide (wider than in adults, see Table 1 View TABLE 1 ); pronotal surface with distinct central line. Wing pads visible, well developed, reaching second abdominal tergite (first visible), indicating that this semaphoront is probably in fifth stadium; wing pads of mesonotum extended to metanotum ( Fig. 7E View FIGURE 7 ). Fore, middle, and hind legs preserved ( Fig. 7D, F, G View FIGURE 7 ), some fringes of natatorial setae visible; tarsi apparently dimerous; tarsal claws visible in all legs ( Fig. 7D, F, H View FIGURE 7 ). Abdomen ( Fig. 7B View FIGURE 7 ) roughly triangular; six segments visible (II–VII, Fig. 7A View FIGURE 7 ); additional details are not possible to observe because of the poor preservation of the abdomen ( Fig. 7B View FIGURE 7 ).
