Brasineura morrense  sp. n.

( Figs 15–23View FIGURES 15–22View FIGURE 23)

Diagnosis (Male). Hypandrium with a posterior projection in the middle, straight, blunt ended; side struts proximally not fused, external parameres distally not forked, with two projections, one elongated, directed outwards, another short, almost rectangular, anteriorly with a small acuminate projection on the outer margin; antero-lateral pair of endophallic sclerites proximally slender, widening posteriorly, slightly curved inwards; a mesal pair elongate, touching in the middle, proximally curved outwards, acuminate, posteriorly slightly curved inwards, blunt ended.

Color (in 80% ethanol). Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 15View FIGURES 15–22). Scape and pedicel brown, f1–f3 brown. Mx4 more pigmented distally. Femora pale brown, tibiae and tarsomeres 1–3 brown. Forewings almost hyaline, as illustrated ( Figs 16, 17View FIGURES 15–22); a small brown spot on confluence of Cu 2 –1 A; veins brown. Hindwing ( Fig. 18View FIGURES 15–22), almost hyaline throughout, veins brown.

Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with five denticles markedly sclerotized ( Fig. 19View FIGURES 15–22). Forewing pterostigma basally narrow, wider in the middle, narrowing posteriorly, areola postica tall, with round apex, left forewing M with four primary branches, M 4 forked, resulting in M 4a and M 4b ( Fig. 16View FIGURES 15–22), right forewing M with four primary branches, M 4 three branched, resulting in M 4a, M 4b1 and M 4b2 ( Fig. 17View FIGURES 15–22, see also variation of the paratype below). Hindwing M vein concave proximally, then almost straight, R 2+3 and R 4+5 slightly sinuous ( Fig. 18View FIGURES 15–22). Hypandrium ( Fig. 20View FIGURES 15–22) straight anteriorly; one concave area on each antero-lateral corner, resulting in a pair of projections on each side, posterior process straight, blunt ended, setae as illustrated. Phallosome ( Fig. 21View FIGURES 15–22) with side struts proximally not fused, posteriorly fused to external parameres, these stout, almost rounded, with a sclerotized ring enclosing a membrane with numerous pores, partially projected out, distally with two projections, an elongated one, directed outwards, another short, almost rectangular, anteriorly with a small acuminate projection on the outer margin. Three pairs of endophallic sclerites; an antero-lateral pair proximally slender, widening posteriorly, slightly curved inwards; a mesal par elongate, touching in the middle, proximally curved outward, acuminate, posteriorly slightly curved inwards, blunt ended; lateral-mesal pair, short, proximally wide, narrowing posteriorly, curved outward, blunt ended. Paraprocts stout, broad, almost triangular, sensory fields with 30–31 trichobothria on basal rosettes, setae as illustrated ( Fig. 22View FIGURES 15–22). Epiproct semi-elliptic; a long seta mesally near each side, other setae as illustrated ( Fig. 22View FIGURES 15–22).

Measurements (in microns). FW: 3398, HW: 2336, F: 1019, T: 1623, t1: 631, t2: 58, t3: 86, f1: 776, f2: 850, Mx4: 225, IO: 246, D: 349, d: 264, PO: 0.75.

Variation of paratype. Left forewing as the holotype, right forewing with M vein four branched, with M 4 three branched, resulting in M 4a, M 4b1 and M 4b2, but with the second bifurcation not as close to the wing margin as observed in the holotype ( Fig. 23View FIGURE 23). Both hindwings as the holotype.

Etymology. The specific name “morrense” is a noun that applies to the natives of Morro do Chapéu, city of the Brazilian state of Bahia. By extension, it is given to this species as a noun in apposition and refers to the city of origin of this species.
