Loneura tendalensis n. sp.

( Figs 17–28 )

Diagnosis. Related to L. boliviana Williner , differing from it in having the posterior processes of the central sclerite of the hypandrium much wider and not curved outwards distally; the median process of the mesal endophallic sclerite is very long, with oblique apex and short and rounded teeth along the posterior border ( Fig. 22 ).

Male. Color. Body light brown. Head brown ( Fig. 19 ), with oblique ochre bands, from the inner margin of each compound eye to the epistomal sulcus. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Vertex light brown. Postclypeus brown, with V-shaped ochre area. Anteclypeus and labrum pale brown. Genae brown to light brown, postgenae light brown. Antennae: scape and pedicel pale brown, flagellomeres 1–3 light brown, with apices cream. Maxillary palps light brown, Mx4 dark brown. Tergal lobes of meso- and metathorax brown. Thoracic pleura light brown. Legs light brown, coxae with brown spot, femora with four brown spots, basal, apical and two median. Wings hyaline, veins brown, with a brown spot at wing margin; forewing pterostigma with proximal and distal brown bands ( Fig. 17 ). Abdomen dark brown, with small, pale cream irregular spots. Hypandrium dark brown; phallosome dark brown. Epiproct cream, paraprocts cream.

Head ( Fig. 19 ) H/MxW: 1.58; compound eyes large, H/d: 2.70; IO/MxW: 0.55; vertex below the level of the upper border of the compound eyes; outer cusp of lacinial tips broad, with 6–7 denticles. Mx4/Mx2: 1.12. Forewings ( Fig. 17 ) L/W: 2.59; pterostigma: lp/wp: 4.36; M five–six branched, if five-branched then M5 forked distally; areola postica: la/ha: 1.48, triangular, apically rounded. Hindwings ( Fig. 18 ) l/w: 2.99; M four-branched. Hypandrium ( Fig. 20 ), posterior processes of the central sclerite wide, distally rounded, setose. Phallosome ( Fig. 22 ) anteriorly V-shaped, with slender side struts; external parameres sclerotized, wide, elongate, distally rounded, bearing abundant pores, a row of short teeth along the outer borders. Phallosome with two pairs of endophallic sclerites; anterior pair large, laminar, curved downward and posteriorly, with tapered processes directed antero-laterally. Mesal sclerite with anterior processes tapered and curved outwards; posterior processes long. Paraprocts ( Fig. 21 ) oval, with setal fields distally and a field of microspicules; sensory fields with 24 trichobothria on basal rosettes. Epiproct ( Fig. 21 ) slightly convex anteriorly, broadly rounded posteriorly, with setae and a field of microsetae along posterior border.

Female. Color. Body, head, legs, epiproct, paraprocts and wings as in the males. Subgenital plate with large, V-shaped pigmented area, deeply concave in the middle ( Fig. 26 ). IX sternum light brown, with posterior hyaline areas. Gonapophyses: v1 hyaline, with long dark brown longitudinal band, v2+3dark brown, hyaline apically.

Morphology. Head ( Fig. 25 ) H/MxW: 1.51; large compound eyes, H/d: 3.33; IO/MxW: 0.65; vertex slightly below the level of the upper border of the compound eyes; outer cusp of lacinial tips broad, with 6–7 denticles. Mx4/Mx2: 1.14. Forewings ( Fig. 23 ) L/W: 2.59; pterostigma: lp/wp: 4.34, elongate, wider in the middle; M five branched, M5 forked; areola postica: la/ha: 1.27, tall, apically rounded. Hindwings ( Fig. 24 ) l/w: 2.98; M threebranched. Subgenital plate ( Fig. 26 ) wide, posteriorly rounded, setae as illustrated. Gonapophyses ( Fig. 28 ): v1 slen- der, elongate, acuminate, with spicules distally; v2+3 with anterior slender heel, v2 with a row of 5–6 macrosetae; distal process long, acuminate, with abundant spicules distally. Ninth sternum ( Fig. 28 ) widely concave anteriorly, with a transverse pigmented area, concave posteriorly in the middle. Paraprocts ( Fig. 27 ) broad, triangular, with long and short setae, sensory fields with 22–24 trichobothria on basal rosettes. Epiproct ( Fig. 27 ) broadly triangular, wide at base, rounded posteriorly, with macrosetae and short setae mesally and posteriorly.

Material studied. Holotype male. COLOMBIA. Chocó. Riosucio, National Natural Park Los Katios , 7°51’12’’N: 77°09’11.0’’W. 33 m. 25–26.II.2017. Led light trap in forest canopy. N. Carrejo, J. Mendivil and R. González. MUSENUV slide code No. 29300 . Paratypes: 25 males and 6 females, same data as the holotype. MUSENUV slide code 29301 .

Etymology. The specific epithet refers to the type locality, “Cascada Tendal”, in Los Katios National Natural Park, where the types were found.

Group II (Formerly Group III, see García Aldrete et al., 2011 a, 2012)

Hypandrium of one sclerite, resulting from the fusion of the proximal ends of the side sclerites to the central sclerite, extended mesally on each side, and with two posterior projections in the middle, variously shaped, each bearing a macroseta anteapically on the inner margin. Phallosome robust, with stout external parameres distally rounded; anterior pair of endophallic sclerites large, stout, broadly triangular, of two pieces; posterior pair of endophallic sclerites elongate, distally rounded or truncate ( García Aldrete et al. 2011b).
