( Figs 4 View FIGURE 4 , 6 View FIGURE 6 A–F, 21)
Macropterous male. BL 5.03–5.07; HL 0.70–0.77; HW 0.96–1.02; ANT I 0.75–0.80, ANT II 0.63–0.65, ANT III 0.60–0.62, ANT IV 0.68–0.71; EYE 0.26–0.30; PL 1.95–2.00; PW 1.16–1.75; FORELEG: FEM 1.26–1.33, TIB 1.23–1.25, TAR I 0.10–0.12, TAR II 0.20–0.27, TAR III 0.31–0.32; MIDLEG: FEM 1.50–1.62, TIB 1.52–1.53, TAR I 0.13, TAR II 0.40, TAR III 0.33–0.37; HINDLEG: FEM 1.73–1.82, TIB 1.85–1.92, TAR I 0.13, TAR II 0.36–0.38, TAR III 0.34–0.37.
Head, sides and venter of body brown to dark brown. Antennae brown to light brown, with base of segments III and IV darker. Eyes shining black. Articles I-III of rostrum light brown; central region of segment I and entire IV shining black; segment III shining centrally, and pale laterally in basal two thirds. Pronotum dark brown, with border of posterior lobe lighter. Forewing dark brown, with veins lighter; an elongated white macula not starting from humeral angle and distinctly surpassing apex of pronotum; on apex, a white tear-like macula touching the posterior margin of wing, and in front of it, other smaller white rounded macula ( Fig. 4 View FIGURE 4 A). Acetabula orange brown. Coxae, trochanters, and anterior half of femora light brown to yellowish brown; posterior half of femora and tibiae brown. Tarsomeres with intersegmental regions lighter, and middle darker.
Head covered by golden setae, with a pair of small narrow strips at posterior portion impressed and shining, without black denticles. Antennae densely covered by shorter golden setae and few longer dark brown setae. Antennomere I stoutest, curved outward; II thicker than III-IV; III-IV with subiqual width; segment IV fusiform ( Fig. 4 View FIGURE 4 A). Ocular setae present. Rostrum reaching posterior margin of mesoacetabula.
Pronotum covered by short golden setae and longer dark brown setae, with weak longitudinal median carina, more evident in anterior half. Humeri slightly elevated, with outer margin rounded. Posterior angle of pronotum rounded ( Fig. 4 View FIGURE 4 A). Forewings reaching base of genital segments, with distinct veins and covered by golden setae on outer proximal portions. Sides of thorax ( Fig. 4 View FIGURE 4 D) and abdomen, except for abdominal sternite VII ( Fig. 6 View FIGURE 6 D), densely covered by suboval punctations and long golden setae. Intersegmental regions between meso- and metasternum with a pair of small tubercles. Legs covered by long golden setae, without spines or spine-like setae ( Figs. 4 View FIGURE 4 A, C). Grasping comb present on distal 1/5 of fore tibia.
Abdominal connexives and tergites covered by golden and dark brown setae; connexives in lateral view with superior margin shining. Last abdominal sternite without projections or denticles, only with two small lobes ( Fig. 6 View FIGURE 6 D). Dorsum of genital segment I covered by long dark brown setae, with posterior margin notched, forming a small lobe centrally ( Fig. 6 View FIGURE 6 A); venter with anterior margin concave centrally, and posterior margin converging distinctly to the apex ( Fig. 6 View FIGURE 6 C). Proctiger covered by long dark brown setae, more concentrated in dorsal surface; anteriorly with a pair of bilobed projections in superior margin, and inner lobe smaller ( Figs. 6 View FIGURE 6 E–F). Parameres symmetrical, curved in dorsal surface, with a row of light setae on posterior portion of ventral surface ( Fig. 6 View FIGURE 6 E).
Intraspecific variation. A substantial variation in the shape of the apical macula of this species, where one of the two specimens analyzed has the macula medially constricted, represented by a longitudinal white thin line ( Fig. 4 View FIGURE 4 B), while in the other specimen this line does not exist ( Fig. 4 View FIGURE 4 A).
Type-material. Holotype: Brazil, Mato Grosso: macropterous male (DPIC), Nova Xavantina, Mario Viana Municipal Reserve (Bacaba Municipal Park), Córrego Bacaba, 14o43’14.80”S / 52o21’35.63”W, 11.X.2003, (S.O. Pagioro). Paratype: 1 macropterous male (MZUSP), Córrego da Mata, fourth order, 15o01’32”S / 52o26’29”W, 17.XI.2005, [1788], (H.S.R. Cabette et al.).
Distribution. Known so far from the Mato Grosso State ( Fig. 21 View FIGURE 21 ), central-western Brazil.
Etymology. bi - (Latin), two; lob -, lobe; and suffix - ata (Latin), characterized by having; referring to the pair of bilobed projections on dorsal surface of proctiger, unusual in the genus.
Discussion. The new species has the same suboval punctations on sides and venter of body as P. amapaensis sp. nov., P. a n t a, P. dilatata , P. foveata and P. hungerfordi . However, it is separated from these species by the maculae on the forewing ( Figs 4 View FIGURE 4 A–B); posterior margin of the first genital segment notched, with a small median lobe ( Fig. 6 View FIGURE 6 D); and by the pair of bilobed projections ( Figs. 6 View FIGURE 6 E–F) on basal region of proctiger. Paravelia anta also has a pair of basal projections on proctiger, but similar to horns.
