Colour and pilosty. Dorsum of body brown with central part of thorax and abdomen yellowish; pronotum with anterior lobe bearing an anterior transverse yellow band (Fig. 11), posterior lobe with central area yellow; connexiva yellow with margins shiny black; antennae and all legs dorsally brown, rostrum I–III segments and all legs ventrally yellow, rostral segment IV shiny black. Venter of pro- and mesosternum yellow, metasternum brown; abdominal sternites grey, and central portions yellow; ventral side of abdomen with black spots (Fig. 12). Body covered on dorsum and sides by short, golden setae, these more abundant on abdomen.

Antennomeres cylindrical, IV fusiform; segment I thicker than others, curved outward. Rostrum slightly passing middle of mesosternum; length of rostral segments III> IV> I> II. Head bearing a pair of dorsal pits, near the corner of each eye (Fig. 1).

Pronotum divided into anterior and posterior lobes (Fig. 11); lateral margins divergent, without median carina. Pronotal and propleural surfaces covered with scatered foveae. Thoracic sternites without tubercles (Fig. 13). Mesoacetabulum with a deep circular fovea on inner ventral area (Fig. 13).

Abdomen with lateral margins rounded, wider on segment V, convergent to end of body (Fig. 11). Connexiva slightly elevated at angle of 10º, without acute projections on posterolateral angles of tergite VIII (Fig. 11).

Posterior margin of abdominal sternite VII concave (Fig. 14), genital segments with longer yellow setae (Fig. 14). Parameres slightly asymmetrical (Fig. 15).

Legs with all trochanters unarmed; fore femur bearing a small, black tooth at the base from ventral margin and a spine on apical third (Fig. 16); fore tibia weakly expanded with grasping comb evident on apical one-fourth (Fig. 17); hind femur slender, bearing a ventral row of six small spines, with one larger spine on distal third (Fig. 17); hind tibia bearing two sets of perpendicular setae at the apex (Fig. 17).

Apterous female (Figs. 18, 19). BL 3.16, HL 0.62, HW 0.82; ANT I–IV: 0.46, 0.36, 0.54, 0.58; INT 0.44, EYE 0.22, PL 0.78, PW 1.40. FORELEG: FEM 0.90, TIB 0.76, TAR I–III: 0.04, 0.10, 0.16; MIDLEG: FEM 1.18, TIB 1.04, TAR I–III: 0.04, 0.20, 0.34; HINDLEG; FEM 1.30, TIB 1.48, TAR I–III: 0.04, 0.20, 0.28.

Body covered with very long, recumbent silvery setae, especially on posterior corners of head, pronotum and abdominal tergites I–III (Fig. 18).

Body wider; legs lacking spines, grasping comb absent. Abdominal tergite VIII widened and flattened bearing long, erect, brown setae along lateral and posterior margins (Fig. 18). Ventrite VII with rounded apex (Fig. 19) and posterior margin bearing a row of long, brown setae (Fig. 19).

Macropterous female (Figs. 20, 21). BL 3.32, HL 0.54, HW 0.78; ANT I–IV: 0.42, 0.32, 0.50, 0.54; INT 0.40, EYE 0.20, PL 1.12, PW 1.34. FORELEG: FEM 0.80, TIB 0.60, TAR I–III: 0.02, 0.08 0.16; MIDLEG: FEM 0.90, TIB 0.80, TAR I–III: 0.04, 0.16, 0.30; HINDLEG; FEM 1.26, TIB 1.44, TAR I–III: 0.04, 0.20, 0.28.

Similar to apterous female in general structure and coloration with following exceptions: body brown, antennae and dorsal legs brown, ventral legs yellow. Head bearing a pair of shiny black, dorsal pits, near the corner of each eye (Fig. 20, 21).

Pronotum brown covered with black punctations and short, semirecumbent, golden setae; subpentagonal, with longitudinal dark brown median carina; humeri slightly elevated with posterior margin rounded (Fig. 20). Anteclypeus, posterior corner of head (Fig. 21), half of the posterior margin of pronotum (Fig. 20) and lateral regions of abdominal tergites I–III covered with very long, recumbent silvery setae.

Forewings pale brown with veins concolorours and some transparent areas mainly in the membrane (Fig. 20). Comparative notes. Paravelia acantha sp. n. is similar in appearance and shape of the body, pronotum and mesoacetabulum to P. capixaba Moreira, Nessimian & Rúdio, 2010 but differs in the others characters. Specimens of P. acantha can be diagnosed by the presence of spines on the fore and hind femora (Figs. 16, 17), and by having the parameres asymmetrical and semitriangular (Fig. 15).
