Type material examined
Holotype. ♂ ‘ Baoguosi Temple, Mts. Emeishan , Sichuan, 4.IV.1957, 550– 750 m, leg. Huang Keren’ ( IZAS) . Paratype: 1 ♂ ‘ Mts. Zhibenshan, Yunlong , Yunnan, 20. VI.1981, 2500 m, leg. Zhang Xuezhong’ ( ZFMK) .
Description
Length. 7.7 mm, length of elytra: 5.9 mm, width: 4.2 mm. Body oblong, dark yellowish brown, antenna yellow, dorsal surface dull and nearly glabrous.
Labroclypeus subtrapezoidal, widest at base, lateral margins weakly convex and moderately convergent to weakly rounded anterior angles, lateral border and ocular canthus producing a distinct blunt angle, margins weakly reflexed, anterior margin distinctly sinuate medially; surface nearly flat and shiny, finely and densely, irregularly punctate, with a numerous long erect setae in coarser but superficial punctures; frontoclypeal suture feebly incised and medially weakly angled; smooth area in front of eye approximately 1.5 times as wide as long; ocular canthus moderately long and slender, very finely and sparsely punctate, with a fine terminal seta. Frons dull, with fine and sparse punctures, with moderately dense and long setae. Eyes moderately small, ratio of diameter/interocular width: 0.65. Antenna with 10 antennomeres; club with four antennomeres, little longer than remaining antennomeres combined. Mentum convexly elevated anteriorly.
Pronotum moderately wide, widest at base, lateral margins evenly curved and weakly narrowed anteriorly, anterior angles distinctly produced and sharp, posterior angles blunt and slightly rounded at tip, anterior margin convexly produced medially, broad marginal line widely missing, basal margin without marginal line; surface with moderately dense and fine punctures, with minute setae only; anterior and lateral borders sparsely setose; hypomeron distinctly carinate at base. Scutellum narrow and long, sharp at apex, with fine and moderately dense punctures and minute setae.
Elytra oblong, widest in posterior third, striae distinctly impressed, finely and densely punctate, intervals weakly convex and not densely punctate, intervals with punctures concentrated along striae, odd intervals with some single, fine setae; epipleural edge robust, ending at strongly curved external apical angle of elytra, epipleura densely setose, apical border membranous, with short microtrichomes.
Ventral surface dull, with large and dense punctures, sparsely and shortly setose, setae partly adpressed; metacoxa glabrous, with fine setae laterally, apical margin convex and external apical angle rounded; each abdominal sternite with a distinct transversal row of coarse punctures each bearing a short seta between fine and moderately dense punctation. Mesosternum between mesocoxae nearly half as wide as mesofemur, with irregularly scattered, fine setae. Ratio of length of metepisternum/metacoxa: 1/1.41. Pygidium moderately convex, finely and moderately densely punctate, with wide, smooth midline, with sparse, long setae on apical half.
Legs slender; femora with two longitudinal rows of setae, finely and moderately densely punctate; metafemur ventrally dull, anterior margin sharply carinate, without a submarginal serrated line, posterior margin moderately convex, with a few strong setae medially, only weakly widened externally in apical half and not serrated ventrally in distal half, finely serrated dorsally, with dense, short setae. Metatibia slender and long, widest at apex, ratio width/length: 1/4.2, dorsal margin moderately carinate, with two groups of spines, basal group of spines shortly before half of metatibial length, apical one at about three quarters of metatibial length, basally with a few single fine spines; external face longitudinally convex, with fine, sparse punctures; ventral margin finely serrated, with four fine, equidistant spines; medial face impunctate, apex concavely truncate interiorly near tarsal articulation. Tarsomeres dorsally finely punctate, with a few long setae, with sparse, short setae ventrally; metatarsomeres impunctate and glabrous dorsally, with a strongly serrated ridge ventrally and glabrous, and with a fine longitudinal carina immediately beside it; first metatarsomere slightly shorter than following two tarsomeres combined and slightly longer than dorsal tibial spur. Protibia long, bidentate, protarsal claws symmetrical, basal tooth of inner protarsal claw bluntly truncate apically.
Aedeagus. Figure 3E–G View Figure 3 . Female unknown.
Diagnosis
The new species differs from all other species of the N. vulpes group by having the parameres distinctly shorter than the ventral process of phallobase ( Figure 3 View Figure 3 ).
Etymology
The new species is named after one of its collectors, Huang Keren (noun in the genitive case).
Variation
Length. 7.7–8.0 mm, length of elytra: 5.9–6.1 mm, width: 4.0– 4.2 mm.
