description: Brasineura jiboia n. sp.
(Figs 1–15)
Diagnosis. Forewing M five-branched; hindwing M two–branched; antero-mesal pair of the endophallic sclerites bow-shaped; antero-lateral pair of the endophallic sclerites proximally and distally forked; external parameres not forked and ending distally in an acuminate projection, curved outwards.
Male. Color (of parts mounted on a slide). Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern (Fig. 1). Scape and pedicel pale brown, f1–f2 brown, with apex creamy white. Mx4 pale brown. Legs with coxae, trochanters and femora pale yellow, tibiae and tarsomeres yellow. Forewings almost hyaline (Fig. 2); a small brown spot at confluence of Cu2–1A; veins brown. Hindwing (Fig. 3), almost hyaline, veins brown.
Morphology. Compound eyes with interommatidial setae. Outer cusp of lacinial tip broad, with four denticles markedly sclerotized (Fig. 4). Forewing pterostigma elongate, constricted proximally, widest in the middle. Areola postica tall, broadly triangular, with apex rounded. Rs straight, R2+3 almost straight and R4+5 sinuous. M stem slightly concave proximally, then almost straight. M of five primary branches with M5 forked, resulting in M5a and M5b. Hindwing Rs-M joined for a distance, Rs, R2+3 and R4+5 straight, M 2-branched. Hypandrium (Fig. 5) of one sclerite, almost straight anteriorly, with anterior border strongly sclerotized; antero-lateral corners projected, almost quadrangular, one concave area on each, resulting in a pair of small projections on each side, posteriorly U shaped; setae as illustrated. Phallosome (Fig. 6) with side struts proximally fused, posteriorly fused to external parameres, these stout, almost rounded, with a sclerotized ring enclosing a membrane with numerous pores, ending distally in an acuminate projection, curved outwards. Three pairs of endophallic sclerites; antero-lateral pair proximally and distally forked, with inner arms short, almost rectangular, outer arms long, wide based, narrowing distally, acuminate; antero-mesal pair, long, bow-shaped, proximally touching in the middle, posteriorly curved inwards and blunt ended; posterior pair long, wide basally, with sides narrowing posteriorly and curved outwards distally, blunt ended, close to the ends of the external parameres. Paraprocts stout, broad, almost triangular, almost straight proximally, with one small convex area on each antero-lateral corner, sensory fields with 32–33 trichobothria on basal rosettes, setae as illustrated (Fig. 7). Epiproct anteriorly straight, sides converging to round posterior border; a long seta mesally near each side, other setae as illustrated (Fig.7).
Measurements (in microns). FW: 4380, HW: 3199, F: 1111, T: 2010, t1: 803, t2: 96, t3: 159, f1: 915, f2: 832, Mx4: 279, IO: 324, D: 545, d: 409, PO: 0.75.
Female. Color (of parts mounted on a slide). Essentially as in the male.
Morphology. Compound eyes with interommatidial setae (Fig. 8). Outer cusp of lacinial tip broad, with five denticles markedly sclerotized (Fig. 11). Forewing pterostigma elongate, constricted proximally, widest in the middle. Areola postica tall, broad, with apex rounded. Rs straight, R2+3 almost straight, R4+5 sinuous. M stem slightly concave proximally, then almost straight. M of five branches, M4 and M5 forked (Fig. 9). Hindwing Rs-M joined for a distance, Rs straight, R2+3 and R4+5 almost straight, M 2-branched (Fig. 10). Subgenital plate broad, sides converging to a pointed apex; pigmented area wide along sides and posterior border; setae as illustrated (Fig. 12). Ninth sternum (Fig. 13) broad, with three distinct areas, anterior area almost elliptic, anteriorly concave in the middle, posteriorly pointed; mesal area almost elliptic, anterior border with a small concavity in the middle and posterior border with a deep cleft in the middle; posterior area V shaped, wide crosswise, with antero-lateral corners projected, with two small almost triangular projections on each side, posteriorly ending in a membranous convex apex. Gonapophyses: v1 stout, wider in the middle, narrowing at the ends and distally acuminate; outer edge and ends heavily sclerotized; v2 +3 broad, narrowing at the ends, with long, almost rectangular heel; five setae on outer lobe, distal process slender, short and distally acuminate (Fig. 14). Paraprocts broad, almost triangular, with setal field towards outer and posterior margins, sensory fields with 32–33 trichobothria on basal rosettes (Fig. 15).
Measurements (in microns). FW: 4607, HW: 3223, F: 1110, T: 1948, t1: 796, t2: 90, t3: 137, f1: 905, f2: 810, Mx4: 260, IO: 465, D: 454, d: 306, PO: 0.67.
Etymology. The specific epithet is a name in apposition, referring to the type locality, Serra da Jibóia.
