description: Bambusananus cuihuashanensis sp. n. Figs 1-11 Type material. Holotype: ♂, China: Shaanxi, Xi'an, Cuihuashan (108°57'E, 34°10'N), on bamboo, 37 Aug. 2008, J.-D. Li; paratypes: 2 ♂♂, 4 ♀♀, same data as holotype. Etymology. The new species is named after its locality, Cuihuashan, Shaanxi Province, China. Measurements. Body length (from apex of vertex to tip of forewings): male 4.75-4.85 mm (N = 2); female 5.75-5.90 mm (N = 4); forewing length: male 3.95-4.05 mm (N = 2); female 5.00-5.15 mm (N = 4). Coloration. Crown (Fig. 1) pale yellowish white, two markings behind ocelli blackish brown. Eyes (Fig. 1) blackish brown, ocelli yellowish white. Frontoclypeus (Fig. 5) pale yellowish white, with lower area dark brown and a large kidney-shaped black marking at upper area; anteclypeus, lorums, genae with upper areas dark brown. Antennae (Fig. 5) pale yellowish brown. Pronotum (Figs 1, 3) pale yellowish brown, anterior areas with two dark brown markings, posterior areas with four blackish brown markings. Scutellum (Figs 1, 3) pale yellowish brown, with two brown markings basally. Forewing (Figs 1, 2) pale yellowish white to yellowish brown, veins yellowish white, with irregular blackish brown markings at median and posterior region. Thorax dark brown ventrally; legs brown to dark brown, except base of tarsus yellowish brown. Abdomen dark brown dorsally and ventrally, lateral margins of each segment pale yellowish white. Head and thorax. External features as in generic description. Crown shorter medially than width between eyes (0.54:1). Pronotum longer medially than crown (2.10:1). Scutellum shorter medially than pronotum (0.89:1). Forewing longer medially than width at widest part (3.38:1). Male genitalia. Male pygofer (Fig. 6) with basal half nearly quadrate, then narrowing to apex, dorsal margin slightly sinuate, ventral margin broadly curved, smooth, apical margin acute and rounded, with several macrosetae at apical area; ventral process slender and long, slightly widening at middle, narrowing apically, arising from inner side of ventral margin, produced dorsad, then abruptly strongly curved ventrally. Genital valve (Fig. 7) triangular, basal width slightly longer than median length (1.06:1). Subgenital plate (Fig. 7) moderately narrow, triangular, inner margin nearly straight, outer margin slightly concave, narrowing apically, apex acute and rounded, with row of macrosetae laterally. Style (Fig. 8) broad at base, abruptly narrowing subapically and curved hook-like. Aedeagus (Figs 10, 11) with shaft broad at middle, narrowing basally and apically, gonopore at apex, paired appendages slender and long, apex acute, arising from apical one-fourth, directed basally, then laterally. Connective (Fig. 9) Y-shaped, stem robust and arms well developed, stem slightly shorter than arm (0.79:1). Host plant. Bamboo. Distribution. China (Shaanxi) (Fig. 12). Remarks. This new species is similar to Bambusananus bipunctatus (Li, 1999) in general appearance, but can be distinguished by: pygofer in lateral view with ventral margin broadly smoothly rounded, without notch at base of ventral process (with notch in Bambusananus bipunctatus); connective with stem slightly shorter than arms (longer in Bambusananus bipunctatus); aedeagal shaft with appendages longer, in lateral view with apex reaching to middle of aedeagus (in Bambusananus bipunctatus, appendages shorter and apex only reaching to apical one-fifth of aedeagus). This new species is also similar to Bambusananus lii (McKamey &amp; Hicks, 2007), but can be distinguished by: upper area of frontoclypeus with a large kidney-shaped black marking (lacking in Bambusananus lii); ventral margin of pygoger without any lobe (with a lobe near middle in Bambusananus lii); appendages of aedeagal shaft mostly straight basally, apex directed laterally (elbow-like and curved basally, apex directed caudad in Bambusananus lii); ventral margin of aedeagus without any teeth (with a row of teeth at middle in Bambusananus lii).
