Loneuroides baianus sp. nov. Female ( Figures 1-8)

Diagnosis: Vein M of forewing six-branched with one crossvein between A2 and the wing margin. Hindwing M two-branched. Ninth sternum broad, trapeziform, anteriorly wide, concave in the middle; sides converging towards a membranous convex apex, an anterior transverse sclerotized band concave in the middle, a mesal and a posterior transverse sclerotized bands convex and slightly concave in the middle, respectively in the middle. V2+3 with a row of seven large setae on v2, posterior process straight, distally with a field of microspines, v1 long, slender.

Color: Body yellow, with ochre brown spots. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 2). Scape brown, pedicel dark brown, f1-f3 yellow with proximal ends brown, rest of each flagellomere white. Mx1-Mx2 pale yellow, Mx3-Mx4 yellow. Femora yellow; tibiae pale brown with distal ends dark brown, tarsomere 1 pale brown, tarsomeres 2-3 brown. Forewings with a marginal, slender, pigmented brown band from R4+5 to confluence of Cu2-1A, with two hyaline areas between each intersection of the veins and the edge of the wing; a dark pigment spot at the base of each setae on the basal section of vein R, M+Cu1 and A1, pterostigma brown with a hyaline area in the lower angle. Veins pale brown, with dark brown areolae on setal insertions ( Fig. 3). Hindwings almost hyaline, with a small, pale brown area proximally and a small pale brown spot at confluence of CuP and wing margin; veins brown, with brown spots at wing margin ( Fig. 4).

Morphology: Head with vertex concave in the middle, slightly above the level of the upper border of the compound eyes; compound eyes without interommatidial setae ( Fig. 2). Outer cusp of lacinial tip broad, with seven denticles ( Fig. 5). Forewing pterostigma narrow basally, wider in the middle, slightly extended towards Rs; areola postica tall, triangular, with apex rounded; M stem slightly concave proximally, then almost straight ( Fig. 3). Hindwing M two-branched ( Fig. 4). Subgenital plate broad, sides converging to a pointed apex; pigmented area wide along sides and posterior border; setae as illustrated ( Fig. 6). Ninth sternum ( Fig. 7) broad, trapeziform, anteriorly wide, concave in the middle; sides converging towards a membranous convex apex. Gonapophyses ( Fig. 7): v1 heavily sclerotized, distally acuminate, v2+3 proximally wide, with a pointed heel. Paraprocts almost triangular, broad, sensory fields with 33 trichobothria on basal rosettes; setae as illustrated ( Fig. 8). Epiproct triangular, with a group of three mesal setae, other setae as illustrated ( Fig. 8).
