Description. Adult. Coloration. Yellowish, straw-coloured to brown; clavus dark brown to almost black, remigium lighter.
Structure. Body, in dorsal view, narrowly ovoid. Head with weakly curved fore margin; anterior rim indistinctly delimited from membrane; areolae, in longitudinal body axis, relatively short; eyes moderately recessive; hind margin of eye and postero-lateral margin of head forming an obtuse angle or evenly rounded depression. Pronotum with distinct median longitudinal ridge, smooth posteriorly, rarely strigate, at most finely punctate laterally. Paranota relatively large with broadly curved margins; smooth postero-ventrally. Tegmen with vein M reduced basally, basal radial cell rarely with faint additional veins in apical half of vein M+CuA. Male and female terminalia as in Figs. 32, 39, 46, 53, 60, 72, 73. Male anal tube broadly oval, in dorsal view, widest in basal quarter, evenly narrowing to apex. Pygophore with comparatively short and wide median posterior tooth; postero-lateral edges irregularly rounded. Parameres moderately long, subacute apically. Aedeagus, in anterior view, with narrowly rounded head distally, and obtusely rounded antero-proximal lobes; posterior outline of neck, in profile, with distinct angle; spines on neck long, coarse and numerous. Female tergite 9 with ventral margin weakly curved in apical third. Ventral teeth of valvulae 1 moderately large.
Measurements and ratios in Tables 1 and 2.
Fifth instar (Fig. 79). Anterior head margin weakly convex or almost straight. Posterior lobes of abdominal segment 9 stout, blunt apically; ventrite 9 covered with setae but lacking microscopical spinules; rear margin of male genital capsule, in ventral view, ending laterally more distally than medially (Fig. 85). Measurements and ratios in Table 3.
Etymology. From Greek ράχɩς = back and λόφος = crest, referring to the crested pronotum.
