DESCRIPTION
Head shape, tympanum, legs and wings as in genus definition. DD anterior margin slightly convex. TIII with four (right) or five (left) inner, and five outer subapical spurs. Inner serrulation: no spine between dorsal apical spur and subapical spur 1; one spine between subapical spurs 1 and 2, and between subapical spurs 2 and 3; three spines between subapical spurs 3 and 4; two spines between left subapical spurs 4 and 5; 11 (left) and 16 (right) spines above last (proximal) subapical spur. Outer serrulation: no spine between dorsal apical spur and subapical spur 1, and between subapical spurs 1 and 2; one spine between subapical spurs 2 and 3; two or three spines between subapical spurs 3 and 4; four spines between subapical spurs 4 and 5; 17 (left) and 18 (right) spines above last (proximal) subapical spur.
Coloration
Head dorsum ( Fig. 1D View FIG ) black with yellow pattern, limited anteriorly by a wide, transverse yellow band: one short line behind each eye, extending yellow line on eye and pronotum (see below); a yellow line along inner margin of each eye, prolonged posteriorly to occiput and anteriorly to transverse yellow band; on occiput, a pair of short, convergent yellow lines. Between eyes, yellow transverse band crossed by a thin black Y-shape line, located behind ocelli; this band abundantly covered with golden setae, and delimited anteriorly and posteriorly by a yellow transverse line; anterior transverse yellow line crest-like, including ocelli. Fastigium ( Fig. 1D View FIG ) brown; sides yellow; median part below median ocellus black. Eyes ( Fig. 1B View FIG ) brown, crossed by a pair of parallel, longitudinal yellow lines; upper anterior half yellowish, extending yellow transverse band on head dorsum. Scapes dark brown, lightler at base. Antennae brown at base (broken in holotype). Cheeks ( Fig. 1C View FIG ) dark brown; lower margins lighter. Area behind eyes dark brown, marbled with yellow. Face ( Fig. 1B View FIG ) black, shining, largely bordered with light yellow along epistemal suture. A small, light yellow dot under lower angle of each eye. Clypeus and labrum light yellow; upper margin of postclypeus and labrum, and complete margin of preclypeus dark brown. Palpi dark brown. DD black with yellow pattern ( Fig. 1A, C View FIG ): a yellow band along lateral margins, extended on anterior margin, and almost interrupted after midlength; a small median dot on anterior margin; a pair of median, oval dots close to posterior margin; a small, median longitudinal line in DD posterior 1/4. Lateral lobes dark brown, slightly lighter in anterior angle; an inconspicuous longitudinal yellowish line at midlength; a small yellow line on upper anterior margin. Legs: Coxae I black, yellow and white. Trochanter white. FI black, with yellow dots dorsally ( Fig. 1A View FIG ). TI light brown; three or four yellow dots on upper, inner margin. Tarsi I and II light brown; distal part of tarsomeres 2 and 3 yellowish. Coxae II and trochanters II black and white. FII brown; dorsal base yellow; yellow dots on distal dorsal part and on outer side. TII dark brown; three or four yellow dots on upper, outer margin. FIII ( Fig. 1E View FIG ) dark brown in apical 1/4; a wide, longitudinal brown line on outer side; FIII otherwise light yellow with brown dorsally, and whitish ventrally (on both inner and outer sides). TIII brown dorsally, lighter ventrally; four whitish lines along inner margin; spurs light yellow, darker at base and apex; basitarsi III white; spines white with black apex, spurs light yellow; tarsomeres 2 brown; tarsomeres 3 light yellow. Cerci black laterally, white dorsally and ventrally.
Male
Metanotum glandular ( Fig. 1F View FIG ). FWs black, with a wide, yellow band along dorsal field lateral margins; veins dark brown to black, except along FW outer margin ( Fig. 1A View FIG ). Tergites black, their distal margin bordered with yellow. Sternites black, shining, their lateral parts light yellow. Subgenital plate black, its lateral margin inconspicuously marked with whitish.
Male genitalia. Fig. 2 View FIG D-F. Small compared to N. loretensis n. gen., n. sp. Pseudephallic lophi slightly asymmetrical, almost parallel, regularly and only slightly narrowed toward apex; pseudepiphallic plate connected to parameres quite posteriorly, distal margin strongly protruding and conical; pseudepiphallic parameres with a small outer lobe, its main lobe conical and regularly narrowed toward apex; ectophallic apodemes broad, located laterally related to dorsal cavity.
Female unknown.
