Diagnosis. N. magnatitilana   sp. n. can be readily distinguished from its congeners by the following characters: (1) Male A7–A8 yellowish white, male genital bulb blackish brown ( Fig. 12f & g View FIGURE 12 ); (2) paramere with dorsal

process large, wing-like, projecting dorsad ( Fig. 13a –c View FIGURE 13 ); (3) female subgenital plate brown with shallow V-shaped emargination ( Fig. 13d View FIGURE 13 ); genital plate with axis extending anteriorly beyond main plate for half length; posterior arms widely divergent ( Fig. 13e –g View FIGURE 13 ).

Etymology. The specific name is derived from Latin magna (large) and titilana (process), referring to the large conspicuous dorsal process of the aedeagus.

Description. Holotype ( Fig. 12a View FIGURE 12 ).

Head ( Fig. 12c View FIGURE 12 ). Vertex and ocellar triangle black. Rostrum yellowish brown with two blackish brown longitudinal stripes along clypeus, darkened at apex.

Thorax ( Fig. 12d View FIGURE 12 ). Pronotum black. Mesonotum black at anterior half, extending caudad as longitudinal median band to scutellum, leaving yellowish white patches adjacent to wing bases; metanotum with similar pattern.

Wings ( Fig. 12a View FIGURE 12 ). Membrane hyaline with grayish brown markings; R2 bifurcated. In forewings, apical band extending to M1 or M2; pterostigmal band broad, with apical branch absent and basal branch running obliquely to posterior margin; submedian band reduced to a spot over CuA and CuP. Hindwings similar to forewings, but markings more weakly expressed.

Abdomen: T1–T5 blackish brown ( Fig. 12a & e View FIGURE 12 ). Male A6 black, A7–A8 yellowish white, narrowly bordered with brown caudally ( Fig. 12f View FIGURE 12 ). Notal organ triangular, extending to half length of T4; T4 membranous anteriorly, bearing hirsute flat post-notal organ ( Fig. 12e View FIGURE 12 ).

Male genitalia. Black. Hypandrium with a basal stalk and a pair of distal hypovalves, hypovalves twice the length of basal stalk ( Fig. 12g View FIGURE 12 ); hypovalves membranous in apical half, extending to basal lobe of gonostylus, twisted ventro-mesad, touching at apices, bearing minor hypandrial processes ( Fig. 12g View FIGURE 12 ); in lateral view, hypovalves slightly expanded dorsad, apices curved ventrad, hypandrial processes only slightly produced, barely visible ( Fig. 12i View FIGURE 12 ). Epandrium tapering toward apex, abruptly membranous at apex, emarginated shallowly ( Fig. 12h View FIGURE 12 ); epandrial lobes broad, extending ventro-mesad ( Fig. 12i View FIGURE 12 ). Gonostylus blackish brown, median tooth blunt; basal lobe cup-like, concaving with a line of dorsal setae ( Fig. 12j & k View FIGURE 12 ). Ventral valves of aedeagus spatulate, projected ventrad ( Fig. 13b View FIGURE 13 ); dorsal valves stout, concealed in ventral aspect ( Fig. 13a –c View FIGURE 13 ). Paramere with long basal stalk, and bifurcated distally into ventral and dorsal branches; ventral branch slender, indistinct; dorsal branch slender, elongated dorso-laterally ( Fig.13b View FIGURE 13 ); lateral process greatly expanded, curved ventro-mesally, rounded apically; dorsal process large, wing-like, projecting dorsad ( Fig.13a –c View FIGURE 13 ).

Female (Paratype) ( Fig. 12b View FIGURE 12 ). Similar wing pattern and body coloration as in the male. T1–T6 blackish brown, A7–A8 pale ( Fig. 12b View FIGURE 12 ). Subgenital plate brown, membranous on mesal line, with shallow emargination ( Fig. 13d View FIGURE 13 ). Genital plate with axis extending anteriorly beyond main plate for half its length, slightly forked proximally; posterior arms broad spatulate, twisted and narrowed subbasally, widely divergent ( Fig. 13e –g View FIGURE 13 ).

Measurements. Male (n = 10), forewing length 13.65 ± 0.39 mm, width 3.15 ± 0.16 mm; hindwing length 12.39 ± 0.48 mm, width 2.9 ± 0.13 mm. Female (n = 7), forewing length 13.73 ± 0.47 mm, width 3.17 ± 0.16 mm; hindwing length 12.66 ± 0.44 mm, width 2.92 ± 0.13 mm.

Variability. In some individuals, wing markings greatly reduced, with only a stripe of pigment on the pterostigma, and an incomplete apical band.

Remarks. This new species resembles N. liquifascia Byers, 1999   in wing markings, however only the female of N. liquifascia   is known. The meso- and metanotum have a black sagittal stripe in both males and females of N. magnatitilana   sp. n., but are entirely dull black in N. liquifascia   . In the female genital plate, N. liquifascia   has an extra sclerite beneath the main plate.
