Type material.

Holotype: China • ♂; Fujian Province, Wanmu Forest Provincial Nature Reserve ; 27°05'N, 118°15'E; sweeping, 20 May 2012; Jian-Kun Long leg.; IEGU . Paratypes: China • 2 ♂♂, 4 ♀♀; Fujian Province, Wanmu Forest Provincial Nature Reserve ; 27°05'N, 118°15'E; sweeping, 20 May 2012; Jian-Kun Long and Zhi-Min Chang leg.; IEGU . 11 ♂♂, 8 ♀♀; Fujian Province, Wanmu Forest Provincial Nature Reserve ; 27°05'N, 118°15'E; sweeping, 27 August 2019; Yong-Jin Sui, Zhi-Cheng Zhou and Xiao-Ya Wang leg.; IEGU .

Diagnosis.

The salient features of the new species include: general color (Figs 4 , 5 ) brown; frons (Fig. 19 ) with lateral carinae divergent from middle to near postclypeus; pygofer (Fig. 23 ) in lateral view ventral 1 / 3 nearly triangular; endosoma (Figs 26–28 ) about 2 / 3 length of periandrium, with a cone-like process at apex, ventral part with a long process and apical part with five serrations. This species is similar to N. spinellosa Wu & Liang, 2003 , but differs from the latter in: (1) gonostyli symmetric (gonostyli asymmetric in N. spinellosa ); (2) endosoma without many small cone-shaped processes at dorsal part (endosoma with many small cone-shaped processes at dorsal part in N. spinellosa ); and (3) ventral part of endosoma with a long process and apical part with five serrations (ventral part of endosoma without a long process and apical part without five serrations in N. spinellosa ).

Description.

Measurements. Total length: male 10.5–12.8 mm (N = 14), female 11.5–13.5 mm (N = 12).

Coloration. General color (Figs 4 , 5 ) brown. Vertex (Figs 4 , 18 ) greyish brown. Eyes (Figs 18–20 ) black. Frons (Fig. 19 ) brownish dark medially, lateral carinae brownish dark at basal 1 / 2. Clypeus (Fig. 19 ) tawny, a little dark brown at lateral parts. Pronotum (Figs 4 , 18 ) yellowish brown to tawny. Mesonotum (Figs 4 , 18 ) reddish brown to brown, with carinae yellowish white. Forewings (Fig. 21 ) brown, with yellowish white markings and stripes, costal area yellowish white, ScP + R and MP red to reddish brown at apical to middle part, remaining veins brown mostly, a few light yellowish brown, as shown in Figure 21 . Hindwings (Fig. 22 ) brown, veins blackish brown.

Head and thorax. Head (Figs 4 , 5 , 18–20 ) small, including eyes distinctly narrower than pronotum (1: 1.58). Vertex (Figs 4 , 18 ) trapezoidal, at base 3.43 times wider than length in midline, apex narrower than base (1: 2.01), slightly projecting in front of eyes, anterior margin concave, posterior margin cambered, recessed, lateral carinae slightly developed, median carina absent, disk slightly depressed. Frons (Fig. 19 ) with lateral carinae developed, divergent from middle to near postclypeus, shorter than clypeus (1: 2.17). Clypeus (Fig. 19 ) with basal part angular on both sides, median carina distinct. Postclypeus (Fig. 19 ) with three longitudinal carinae. Rostrum (Fig. 19 ) long, extends beyond the coxa of hind leg, apical segment slightly longer than width. Eyes (Figs 18–20 ) with basal part slightly concave in ventral view, ocelli below eyes. Antennae (Figs 18–20 ) with pedicel short, elliptic, about 1.9 times as long as wide. Pronotum (Figs 4 , 18 ) with anterior margin angular on both sides, posterior margin concave in inverted V-shaped, shorter than vertex in midline (1: 1.63). Mesonotum (Figs 4 , 18 , 20 ) nearly rhomboid, with median and lateral carinae, longer than 5.63 times pronotum and vertex combined, dorsally elevated, in lateral view raised above vertex distinctly. Forewings (Fig. 21 ) 3.98 times as long as widest point, MP six times branched, MP 1 four times branched with six terminals. Hindwings (Fig. 22 ) with vein ScP + RA short, MP two terminals, CuA two terminals. Spinal formula of hind legs 5-6 - 3 (4).

Male terminalia. Pygofer (Figs 23 , 24 ) narrow, basal 1 / 3 narrowest, in lateral view ventral 1 / 3 nearly triangular, dorsocaudal angle slightly produced; in ventral view widest in the middle. Anal tube (Figs 23 , 29 ) slightly long, in lateral view tapering to ends, basal part obtuse, apical part cuspidal, median part of dorsal margin angularly produced; in dorsal view, basal part with a long stout process on both sides, lateral margins slightly curved, narrows towards the end, apical margin concave, form a small process on both sides; anal style small, sets at basal 1 / 2. Gonostyli (Figs 23–25 ) symmetrical, basal 1 / 3 slender, then rapidly expand; in lateral view tapering to apex, apical part cuspidal, inner and dorsal margins curved, inner side with a hooked process; in ventral view widest at middle part, tapering to apex. Aedeagus (Figs 26–28 ) asymmetrical. Periandrium curved, middle part narrow. Endosoma more complex, tapering to apex, about 2 / 3 length of periandrium, with a cone-like process at apex, directed cephalically, ventral part with a long process and apical part with five serrations, directed ventrocephalad.

Female terminalia. Terminalia reduced (Figs 32 , 33 ).

Host plant.

Phyllostachys heteroclada Oliv. ( Poales : Poaceae : Bambusoideae).

Distribution.

China (Fujian Province) (Fig. 1 ).

Etymology.

The species name is derived from the Latin word “ quinaria ”, referring to the ventral part of the endosoma with a long process and five serrations apically.
