Diagnosis
Bambusiphaga angulosa sp. nov. can be distinguished from the remaining species of the genus by having the vertex and mesonotum without any dark brown markings, the ventral margin of the anal segment without a process, not incised medially, the pygofer without a spine on the ventral margin, the genital styles without a finger-like process at the base, not forked apically, and the aedeagus without small teeth near the apex, forked at the apex.
Etymology
The specific epithet is derived from the Latin word ‘ angulosa ’, referring to the genital styles having an angular process near the apical ⅓.

Description
MEASUREMENTS. Body length including forewing: male 3.7–3.8 mm (N = 4).
COLORATION. General color yellowish. Eyes and ocelli reddish brown ( Fig. 3A–E View Fig ). Forewings pale yellowish orange, veins yellow ( Fig. 3F View Fig ).
HEAD AND THORAX. Vertex ( Figs 3C View Fig , 4A View Fig ) at midline shorter than wide at base (1:1.43), width at apex narrower than at base (1:1.42), anterior margin broadly rounded, lateral and submedian carinae distinct, median carina indistinct. Frons ( Figs 3E View Fig , 4B View Fig ) in middle line longer than wide, at widest part about 2.33: 1, as wide at base as at apex, median carina simple. Base of postclypeus ( Figs 3E View Fig , 4B View Fig ) wider than apex of frons. Antennae ( Figs 3E View Fig , 4B View Fig ) with basal segment with length subequal to width, shorter than second segment (1:3.41). Pronotum ( Figs 3C View Fig , 4A View Fig ) slightly longer than vertex medially (1: 0.92). Mesonotum ( Figs 3C View Fig , 4A View Fig ) 1.48 × as long as vertex and pronotum together in middle line. Forewings ( Fig. 3F View Fig ) longer in middle line than broad at widest part (3.22: 1), transverse venation located in middle near apex.
MALE GENITALIA. Anal segment ( Fig. 4C View Fig ) short, ring-like, ventral margin without a process. Pygofer ( Fig. 4C–E View Fig ) in profile with dorsal margin shorter than ventral margin, opening in posterior view longer than wide, no process at ventral margin. Genital styles ( Fig. 4F–G View Fig ) in posterior view moderately long, narrow and divergent, lateral margins subparallel, sinuate, tapering apically, with an angular process near apical ⅓, in profile ( Fig. 4G View Fig ) with truncate apical margin, near apex with a stout process. Aedeagus without phyllobase. Phallus ( Fig. 4H–I View Fig ) slender, very long, tubular, in profile ( Fig. 4I View Fig ) broad at base, narrowing apically, strongly curved dorsally at basal ⅓ and curved ventrally at apical ⅓, forked at apex, with a node near apex.
Host plant
Bambusoideae.
Distribution
China (Yunnan).
Remarks
This new species is similar to B. parvula sp. nov. in general appearance, but differs in the following: (1) forewings ( Fig. 3F View Fig ) without dark brown mark (vs forewings ( Fig. 1F View Fig ) with a small dark brown mark along cross veins CuP-CuA 1 in B. parvula sp. nov.); (2) genital styles ( Fig. 4F–G View Fig ) with a small process near apical ⅓ (vs genital styles ( Fig. 2F–G View Fig ) with a large process near apical ⅓ in B. parvula sp. nov.); (3) aedeagus ( Fig. 4H–I View Fig ) without spine near apex, forked at apex (vs aedeagus ( Fig. 2H–I View Fig ) with some small spines near apex, not forked at apex in B. parvula sp. nov.).
