Loneura baiana View in CoL n. sp. Male

( Figs 1–9 View FIGURES 1–9 )

Diagnosis. Male. Belonging in species group I, of García Aldrete et al. (2011). This species does not belong in any of the subgroups proposed by these authors. It differs from the species of its group by having the central sclerite of the hypandrium with three posterior projections, one median projection, broad, rounded and two lateral projections, narrow, almost rectangular.

Male. Color. Compound eyes black, ocelli hyaline, with ochre centripetal crescents; head pattern ( Fig. 1 View FIGURES 1–9 ). Scape brown, pedicel pale brown, f1–f3 pale yellow. Mx4 brown. Femora pale yellow; tibiae pale brown with distal ends brown; tarsomeres 1–3 pale brown. Forewings ( Figs 2–3 View FIGURES 1–9 ) almost hyaline, pterostigma with small pale brown bands basally and distallly, a brown spot at confluence of CuP-1 A, veins brown. Hindwing hyaline, veins brown ( Figs 4–5 View FIGURES 1–9 ).

Morphology. Compound eyes without interommatidial setae. Outer cusp of lacinial tip broad, with five denticles ( Fig. 6 View FIGURES 1–9 ). Right forewing ( Fig. 2 View FIGURES 1–9 ) with pterostigma elongate, wider in the middle, narrow basally; areola postica tall, with round apex; Rs straight, R 2+3 almost straight, R 4+5 sinuous; M stem slightly concave proximally, then almost straight, with six primary branches, M 6 forked, resulting in M 6a and M 6b; left forewing M ( Fig.3 View FIGURES 1–9 ) with seven primary branches, M 7 forked, resulting in M 7a and M 7b. Right hindwing M with three primary branches ( Fig. 4 View FIGURES 1–9 ); left hindwing M with four primary branches ( Fig. 5 View FIGURES 1–9 ). Hypandrium of three sclerites, a central sclerite flanked anteriorly by stout, irregular side sclerites, central sclerite anteriorly almost straight, with three posterior projections, one median projection, broad, rounded and two lateral projections, narrow, almost rectangular; setae as illustrated ( Fig. 7 View FIGURES 1–9 ). Phallosome ( Fig. 8 View FIGURES 1–9 ) with side struts basally fused, V-shaped, not fused posteriorly to external parameres, these stout, wide transversely, proximally almost touching in the middle, widening distally, with a field of pores and a concave area formed by a field of tiny spines. Mesal sclerite wide, strongly sclerotized, anteriorly with antero-lateral corners projected, elongated, narrowing to end, distally acuminate, curved outward; posteriorly with two small blunt projections, curved outward, leaving between them a small concavity, with a field of small spines. Three pairs of endophallic sclerites; an anterior pair almost triangular, wider in the middle and narrowing at the ends, with a small field of tiny spines on outer margin close to the field of pores of the external parameres; an antero-lateral pair, anteriorly slender, curved outward, widening posteriorly, bilobed, with numerous small spines in the middle; a posterior pair, almost elliptic, with outer margin end distal area strongly sclerotized, with a small sinuous projection at the ends. Epiproct wide based, posteriorly rounded, with three large mesal setae, next to anterior margin, other setae as illustrated ( Fig. 9 View FIGURES 1–9 ). Paraprocts broad, sensory fields with 34 trichobothria on basal rosettes, setae as illustrated ( Fig. 9 View FIGURES 1–9 ).
