Diagnosis
The salient features of the new species include the following: frons with pale transverse band below level of lower margin of eyes ( Fig. 2B View Fig ); antennal segment I subsagittate, markedly flattened, with median longitudinal carina, the ventral apical angle longer than dorsal apical angle ( Fig. 2B View Fig ); ventral margin of pygofer concave U-shape, without process ( Fig. 2F View Fig ); phallus with basal half broad, compressed, apical half slender, tubular, curved ventrally, acute at apex, with spinous process at basal ¼ and node subapically ( Fig. 2G View Fig ); phallobase with long straight spinous process basally and three processes apically ( Fig. 2G View Fig ); genital styles in posterior view inner margin with two processes ( Fig. 2H View Fig ).
Etymology
The species epithet is derived from the Latin words ‘ bi -’ and ‘ process ’, referring to the inner margin of genital styles with two processes.

Description
MEASUREMENTS. Body length including forewing: male 2.8–2.9 mm (N = 2); female 3.0– 3.1 mm (N = 2); forewing length: male 2.5 mm (N = 2); female 2.6–2.7 mm (N = 2).
COLORATION. General coloration yellowish white to brown ( Fig. 1 View Fig A–F). Vertex, pronotum, mesonotum yellowish white, pronotum and mesonotum with lateral areas brown, base of pronotum, middle areas of mesonotum somewhat light yellow ( Figs 1C View Fig , 2A View Fig ). Frons and genae yellowish brown, except broad transversal stripe below level of lower margin of eyes and narrow stripe of apex yellowish white, along near apex of median carina of frons and inner margin of lateral carinae of genae with several short transversal stripes, yellowish white. Clypeus with basal half yellowish white and apical half dark brown ( Fig. 1E View Fig ). Rostrum yellowish brown, except apex dark brown. Eyes yellowish brown. Ocelli reddish brown. Antennae brown, except lateral margins of first segment yellowish white ( Fig. 1E View Fig ). Legs yellowish white to brown, with dark maculations. Forewing light yellowish white, almost hyaline, basal part near costal margin with big infuscate markings, and apical part from transverse veins to apex with dark brown markings, veins with white spots ( Fig. 1F View Fig ). Wings hyaline with veins dark brown.
HEAD AND THORAX. Head including eyes wider than pronotum ( Fig. 2A View Fig ). Vertex broad transversely, wider at base than long medially about 3.80: 1 ( Fig. 2A View Fig ). Frons in middle line longer than wide at widest part about 1.46: 1, widest above level of lower margin of eyes ( Fig. 2B View Fig ). Postclypeus at base almost as wide as frons at apex ( Fig. 2B View Fig ). Antennae with first segment shorter than second segment about 0.53: 1, second segment cylindrical, longer than wide about 2.80: 1 ( Fig. 2B View Fig ). Pronotum subequal to vertex medially. Mesonotum longer than vertex and pronotum combined about 2.27: 1 ( Fig. 2A View Fig ). Forewing in middle line longer than wide at widest part about 2.73: 1 ( Fig. 2C View Fig ).
MALE GENITALIA. Anal segment small, ring-like ( Fig. 2D View Fig ). Pygofer in profile much longer ventrally than dorsally ( Fig. 2E View Fig ), in posterior view with opening longer than wide, ventral margin concave U-shape, without process ( Fig. 2F View Fig ). Aedeagus with phallobase, phallus with basal half broad, compressed, apical half slender, tubular, curved ventrally, acute at apex, with spinous process at basal ¼ ventrally and node subapically, phallobase long, arising from base of aedeagus, curved at basal ¼, 7-shaped, with long straight spinous process basally and three processes apically ( Fig. 2G View Fig ). Genital styles simple, long, inner margin with two processes ( Fig. 2H View Fig ).
Host plant
Bamboo.
Distribution
China (Hainan).
Remarks
This new species is assigned to the genus Neobelocera because the antennal segment I is subsagittate, markedly flattened, with a median longitudinal carina, the ventral apical angle longer than the dorsal apical angle ( Fig. 2B View Fig ). This species is similar to N. asymmetrica Ding & Yang, 1986 in having the vertex short relatively ( Fig. 2A View Fig ), forewing broad and about 2.7 times as broad as median length, apical margin acutely rounded, with blackish brown markings, and veins with white spots or white short stripes at intervals ( Fig. 1F View Fig ), frons with broad transversal stripe below level of lower margin of eyes yellowish white, along near apex of median carina with several short transversal stripes, yellowish white ( Fig. 1E View Fig ), genae with 2–3 light brown spots ( Fig. 1E View Fig ), male pygofer with ventral margin concave U-shape, without process ( Fig. 2F View Fig ). However, it can be distinguished from the latter by the following features: (1) phallus ( Fig. 2G View Fig ) with basal half broad, compressed, apical half slender, tubular, curved ventrally, acute at apex, with process at basal ¼ and node subapically (in N. asymmetrica , phallus tubular, rounded at apex, without process and node); (2) phallobase ( Fig. 2G View Fig ) curved at basal ¼, 7-shaped, with long straight spinous process basally and three processes apically (in N. asymmetrica , phallobase slender, long and curly, spine-like); (3) genital styles ( Fig. 2H View Fig ) in posterior view inner margin with small processes medially and at basal ¼ (in N. asymmetrica , genital styles in posterior view inner margin without process medially, with a nipple-like process at subapical ¼).
