(Fig. 4)
Diagnosis. This new species is very similar to N. zadok Malicky & Chantaramongkol 1993 from Thailand. It differs in that 1) the apical 1/3 of each inferior appendage is acute, horn-like and curved mesad in ventral view; 2) the preanal appendages are shorter than tergum X and the mesoventral process of each preanal appendage is slender and arched in a semicircle in lateral view, with a dorsoventrally depressed apex (Figs. 4A, 4D); and 3) the pair of phallic sclerites are slender, generally straight and only slightly sclerotized. In N. zadok, 1) each inferior appendage is straight, with a blunt apex; 2) the preanal appendages are much larger and longer than tergum X, each having its mesoventral process triangular with an apex acute in lateral view; and 3) the phallic sclerites are stout, horn-like, and strongly sclerotized.
Male. Length of forewing 4.0– 5.4 mm (N = 10). Head brown with yellowish antennae, pronotum light brown, meso- and metanota brown, fore wings light brown.
Male genitalia. Segment IX in lateral view with triangular protrusion anteriorly in ventral half but with round production posteriorly (Fig. 4A); in ventral view both anterior and posterior margins each with deep concavities such that midline of venter IX only 1/2 as long as segment (Fig. 4C); dorsal region of segment IX nearly membranous, sub-quadrate in dorsal view. Preanal appendages in lateral view (Fig. 4A) each broad at base with rounded apex not passing beyond apex of tergum X; mesoventral processes slender and arched in semicircle; in ventral view (Fig. 4D) much broader basally, nearly meeting on midline to support phallus, but not fused with each other, depressed apically. Tergum X in lateral view with each half divided into two lobes: upper lobe setose and apically beak-like, lower lobe smooth with blunt apex bearing 2 setae (Fig. 4A); in dorsal view (Fig. 4B) transparent, semi-sclerotized, with deep U-shaped incision apicomesally. Inferior appendages broad in lateral view (Fig. 4A), each broad at base, gradually narrowing to acute apex; in ventral view (Fig. 4C) apical 1/3 curved mesad with acute horn-like apex and with thin, translucent, triangular mesal edge. Phallus tube-like, with pair of long, stout and straight paramere spines; phallic sclerites slender, narrow both anteriorly and posteriorly, generally straight and lightly sclerotized; lacking other spines (Fig. 4A).
Holotype male. An-hui Province:, Qi-men County, N 29.8°, E 117.7°, Peng-long-xiang, Xiang-dong-cun, 27 Sep. 2003, Coll. Shan L-n. and Sun C-h.
Paratypes. An-hui Province: Qi-men County, N 29.8°, E 117.7°, Li-xi River: Shuang-he-kou, Tao-yuan-li Tributary, 26 Aug. 2003, Coll. Sun C-h. and Shan L-n., 2 males; same data except 26 Jun. 2003, Coll. Shan L-n. and Lu S., 6 males; same data except at 50 m upstream of Shuang-he-kou, Tang-yun-li Tributary, 30 May 2002, Shan L-n. and Hu B-j., 1 male.
Etymology. Greek, macrorrhinus = big-beaked, with reference to the beak-like apices of the upper lobes of tergum X in lateral view.
Distribution. Oriental Biogeographic Region of China: An-hui.
