Type species: Oxigonia lineosa Walker, 1862: 318 [new. sp. Type loc: Brazil, Rio de Janeiro]; Funkhouser, 1927: 315 [Catalogued: Gelastogonia lineosa ]; Broomfield, 1971: 359 [Designate lectotype male NHMUK]; Metcalf and Wade, 1965: 1055 [Catalogued: Maturnaria ephippigera ; syn. Gelastogonia lineosa ]; McKamey, 1998: 610 [Catalogued: Maturnaria ephippigera ]; Sakakibara 2006 189–192 [new. comb.; sp. rev.; photographs]

Diagnosis. (1) Frontoclypeus extended 1/3 beyond suprantennal margin ( Fig. 2A View FIGURE 2 ); (2) preapical area of posterior pronotal process enlarged ( Fig. 3A View FIGURE 3 ); (3) pronotum brown; (4) style, apical hook straight ( Fig. 12B View FIGURE 12 ).

Description. (Modified from Sakakibara 2006). Color and sculpture. Head, pronotum, legs, and abdomen brown, pronotum contrasting with yellow longitudinal and discontinuous lines. Head. Vertex with longitudinal lines; frontoclypeus projected 1/3 beyond suprantennal margin ( Fig. 2A View FIGURE 2 ). Thorax. Pronotum. In lateral view, preapical part of posterior process higher than metopidium ( Fig. 3A View FIGURE 3 ); in dorsal view, depressed just behind the humeral angles forming a V-shaped groove ( Fig. 4A View FIGURE 4 ). Forewing. R vein bifurcate in two branches R 1+2+3, s crosvein absent ( Fig. 6B View FIGURE 6 ).

Abdomen. Male. Aedeagus ( Fig. 12A View FIGURE 12 ) corona with dorsal margin denticulate; style, ( Fig.12B View FIGURE 12 ) wider basally and narrowing apically, L-shaped, apical hook and shank forming a right angle, margin dorso-apical of hook straight. Female. First valvulae, ( Fig. 13A View FIGURE 13 ) ventral interlocking device (VID) extended from base to approximately 4/5 length of valvula, distinctively sinuous along valvula length; with scattered circular pores (PO); apical area without prominent tooth. Second valvulae, ( Fig. 14A View FIGURE 14 ) apical margin smooth without teeth on ventral or dorsal areas.

Measurements (mm). Male/Female. Body length: 7.00/7.06; pronotum length: 6.42/6.70; pronotum height: 2.09/2.18; head width: 2.60/2.62; head height: 1.48/1.50; distance between apices humeral angles: 3.82/3.84.

Comments. This is the type species of the genus, closely related to N. nanica and N. catarina , which are similar in frontoclypeus characters and pronotal shape and sculpture. In both N. lineosa and N. catarina the s crossvein is absent and the R vein is bifurcate into two branches R 1+2+3 and R 4+5; these may also be diagnostic characters for the lineosa -group but need to be confirmed for N. nanica . N. lineosa is only recorded from Brazil.
