Diagnosis

Bambusiphaga parvula 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 with some small teeth near the apex, not forked at the apex.

Etymology

The specific epithet is derived from the Latin word ‘ parvula ’, referring to the small spines near the apex of the aedeagus.

Type material

Holotype

CHINA • ♂; Yunnan, Yingjiang County; 24°44′ N, 97°33′ E; 20 Aug. 2018; H.X. Li, F.E. Li and N. Gong leg.; on bamboo; GUGU-DE-BA-20180801 .

Paratypes

CHINA • 5 ♂♂; same collection data as for holotype; GUGU-DE-BA-20180802 to GUGU-DE-BA-20180806 .

Description

MEASUREMENTS. Body length including forewing: male 3.8–4.1 mm (N = 6).

COLORTION. General color yellowish ( Fig. 1 ). Eyes light yellow to brown, ocelli reddish brown. Forewings ( Fig. 1F ) pale yellowish orange, with a small dark brown mark along cross veins CuP-CuA 1, veins yellow. Abdomen ( Fig. 1A–B ) with dorsal areas of 5 th to 8 th segments dark brown.

HEAD AND THORAX. Vertex ( Figs 1C , 2A ) at midline shorter than wide at base (1:1.17), width at apex slightly narrower than at base (1:1.08), anterior margin broadly rounded, carinae distinct. Frons ( Figs 1E , 2B ) in middle line longer than wide, at widest part about 2.23: 1, widest at apex, median carina simple. Base of postclypeus ( Figs 1E , 2B ) as wide as apex of frons. Antennae ( Figs 1E , 2B ) with basal segment with length subequal to width, shorter than second segment (1:3.11). Pronotum ( Figs 1C , 2A ) as long as vertex. Mesonotum ( Figs 1C , 2A ) 1.15 × as long as vertex and pronotum together in middle line. Forewings ( Fig. 1F ) longer in middle line than broad at widest part (3.03:1), transverse venation located in middle near apex.

MALE GENITALIA. Anal segment ( Fig. 2C ) ring-like, no process. Pygofer ( Fig. 2C–E ) in profile with dorsal margin shorter than ventral margin, posterior margin distinctly sinuate; in posterior view opening longer than wide, ventral margin broadly concave, without medioventral process. Genital styles ( Fig. 2F–G ) moderately long, apex truncated, arched medially, near apex with spinous process. Aedeagus without phyllobase. Phallus ( Fig. 2H–I ) tubular, broad at base, with some small teeth near apex, in profile ( Fig. 2I ) curved medially.

Host plant

Bambusoideae.

Distribution

China (Yunnan).

Remarks

This new species is similar to B. furca Huang & Tian, 1979 in general appearance, but differs in the following: (1) vertex ( Figs 1C , 2A ) with median carina distinct (vs vertex with median carina indistinct in B. furca ); (2) genital styles ( Fig. 2F–G ) with apex truncated (vs genital styles ( Huang & Ding 1979: fig. 11) with apex acute in B. furca ); (3) aedeagus ( Fig. 2H–I ) thin, with small teeth near apex, not forked at apex (vs aedeagus ( Huang & Ding 1979: fig. 10) stout, without tooth near apex, forked at apex in B. furca ).
