Head dark brown, with lighter areas between midline and eyes on dorsal posterior portion, base of antennomeres and bucculae. Antennae lost. Eyes shining black. Article I of rostrum brown, II-III yellowish brown, IV shining black. Pronotum with anterior lobe brown with silvery pubescence laterally; posterior lobe dark brown ( Fig. 2 View FIGURE 2 A). Forewings brown, with darker veins; a suboval white macula proximally, not reaching humeral angle and surpassing apex of pronotum; and a suboval large white macula distally, not touching apex ( Fig. 2 View FIGURE 2 A). Pro- and metapleura brown, mesopleura dark brown; all with silvery pubescence ( Fig. 2 View FIGURE 2 C). Visible parts of acetabula and venter of thorax brown. Legs brown to dark brown. Exposed portions of connexives dark brown. Abdominal sternites brown, darker laterally. Genital segments brown to dark brown.
Head velvety, with a pair of shining oblique impressions in posterior region, without black denticles dorsally or on bucculae; black denticles on ventral side of antenniferous tubercles and on jugum. Ocular setae present. Rostrum reaching midcoxae.
Pronotum covered by short golden setae and laterally by black setae; central longitudinal carina present, from collar to apex of posterior lobe, posteriorly extended together with posterior angle of pronotum ( Fig. 3 View FIGURE 3 F). Forewings reaching base of genital segments, with some short setae only on outer margin. Transverse rows of rounded punctations present on posterior portion of propleura, anterior portion of mesopleura, and middle of metapleura. Venter of thorax with long black setae. Intersegmental area between meso- and metasternum centrally with two pairs of tubercles. Legs covered by short thick setae and longer thinner setae, more densely on venter of femora. Grasping comb present on distal 1/6 of fore tibia. Fore and middle tibiae, and femora without spines or spine-like setae. Hind femur with two rows of spines - ventralmost with 2–3 obtuse spines, dorsalmost with 9 obtuse spines – and a larger sharper curved spine displaced from the rows.
Connexives covered by brown setae. Venter of abdomen covered by short light setae and small black denticles, larger and more numerous laterally. Last abdominal sternite without carina, depression or projection, with posterior margin concave ( Fig. 2 View FIGURE 2 D). Genital segment I with dorsal anterior margin convex ( Fig. 3 View FIGURE 3 C); posterior region with dark brown setae and rounded posterior margin dorsally ( Figs 3 View FIGURE 3 C–D). Proctiger without expansions or black denticles ( Fig. 3 View FIGURE 3 E). Parameres elongated, with a small notch on dorsal surface near base, several setae on ventral margin, and rounded apex ( Fig. 3 View FIGURE 3 E).
Macropterous female. BL 4.58–4.77; HL 0.61–0.74; HW 0.89–0.90; ANT I 0.64–0.65, ANT II 0.43–0.44, ANT III lost, ANT IV lost; EYE 0.24–0.25; PL 1.56–1.64; PW 1.50–1.58; FORELEG: FEM 1.18–1.25, TIB 1.01– 1.04, TAR I 0.10–0.13, TAR II 0.15–0.18, TAR III 0.23–0.26; MIDLEG: FEM 1.30–1.40, TIB 1.39, TAR I 0.13, TAR II 0.25, TAR III 0.26; HINDLEG: FEM 1.64–1.70, TIB 1.76–1.85, TAR I 0.13, TAR II lost, TAR III lost.
Color and general body structure almost identical to male ( Fig. 2 View FIGURE 2 B). Antennomeres I–II present, light brown, covered by short brown setae and longer thinner brown setae. Antennomere I stoutest, curved outward; segment II cylindrical, less robust than I. Hind femur with 3–4 obtuse spines on ventralmost row, dorsalmost row with 4–5 short spines; larger curved spine less displaced from dorsal row than in males.
Type-material. Holotype: Brazil, Bahia: macropterous male (MNRJ), Salvador, Pituba, VII.1951, (Dalcy). Paratypes: 2 macropterous females (MNRJ), same data as holotype.
Distribution. Known only from the coast of Bahia State ( Fig. 21 View FIGURE 21 ), and the only species of the genus recorded from the area up to the present.
Etymology. Named after the Bahia State, northeastern Brazil, where the type material was collected.
Discussion. The new species can be differentiated from other species of the genus by the presence of black denticles on venter of head and all extension of abdominal sternites, but neither on dorsum of body nor on legs. Black denticles are present on the abdomen of other Paravelia , like P. kahli ( Drake & Harris, 1933) , P. p a r i l i s ( Drake & Harris, 1933), P. nexa (Drake & Harris, 1993) , P. ornata sp. nov., P. rotundanotata (Hungerford, 1930) and P. splendoris ( Drake & Harris, 1933) ; however, the distribution of black denticles on the abdomen of the new species is unique.
In P. o r na t a sp. nov. and P. rotundanotata , black denticles are present on head, thorax, margins of connexives, and sides of last abdominal sternite, but not on center of last abdominal sternite or on other abdominal sternites. The number and shape of forewing maculae also separates these species ( Figs 10 View FIGURE 10 and 18 View FIGURE 18 B respectively). Paravelia kahli , P. parilis , and P. nexa have black denticles on abdominal connexives, but not on sternites, and are shorter than Paravelia bahiana sp. nov., ranging from 3.5 to 4.0 mm. The original description also mentions the presence of lateral triangular teeth on male genital segment I, absent on the new species. Finally, unlike P. bahiana sp. nov., in P. splendoris ( Figs 18 View FIGURE 18 C–D) the entire body is conspicuously armed with black denticles. The spines are prominent and directed upward, whereas they are short and appressed to the body in P. bahiana sp. nov.
