Type material.
Holotype: China • ♂; Yunnan Province, Lushui City; 25°50'N, 98°54'E; sweeping, 8 August 2023; Yong-Jin Sui and Feng-E Li leg.; IEGU. Paratypes: China • 13 ♂♂, 6 ♀♀; same collection data as for holotype; IEGU.
Diagnosis.
The salient features of the new species include: vertex (Fig. 3 A, C) light, without dark brown spots; lateral areas of pronotum (Fig. 3 A, C) with dark brown markings; mesonotum (Fig. 3 A, C) with dark brown markings; forewings (Fig. 3 F) with basal ⅓ black; pygofer (Fig. 4 C, D) with long medioventral and lateroventral processes; inner margin of genital styles (Fig. 4 C, G) with a toothed process at middle part; apical part of aedeagus (Fig. 4 H) with two slender spinous processes. This species is similar to B. taibaishana Qin, 2012, but differs from the latter in: (1) outer part of tegula black brown, inner part yellowish-white (tegula black brown in B. taibaishana); (2) pygofer with a pair long medioventral and a lateroventral processes (pygofer with a short medioventral process, without lateroventral process in B. taibaishana); and (3) inner margin of genital styles with a toothed process at middle part (genital styles without process at middle part in B. taibaishana).
Description.
Measurements. Total length: male 4.7–4.9 mm (N = 14), female 4.9–5.1 mm (N = 6).
Coloration. General color yellowish-white to black (Fig. 3 A – F). Vertex, frons and clypeus yellowish-white. Genae dark brown at base, yellowish-white at apex. Eyes and ocelli reddish-brown. First segment of antennae yellowish-white except for dorsal side dark brown. Pronotum with lateral carinae yellowish-white at inner side, with two dark brown triangular spots, outer side black. Mesonotum black, lateral margins yellow, apex of scutellum yellowish-white. Outer part of tegula black brown, inner part yellowish-white. Forewings pale yellowish-white, hyaline, blackish-brown at basal 1 / 3. Legs yellowish-white, except coxae of fore and median legs dark brown.
Head and thorax. Vertex (Figs 3 C, 4 A) shorter in middle line than wide at base (0.90: 1), width at apex narrower than at base (0.82: 1), middle part of anterior margin convex, lateral margins widened towards the end, lateral and submedian carinae distinct, Y-shaped carina distinct. Frons (Figs 3 E, 4 B) longer in middle line than wide at widest portion (about 2.80: 1), widest at apex, median carina simple. Base of postclypeus (Figs 3 E, 4 B) as wide as apex of frons. Antennae (Figs 3 E, 4 B) with first segment longer than wide, shorter than second segment (1: 2.0). Pronotum (Figs 3 C, 4 A) equal in length to vertex in midline (1.14: 1). Mesonotum (Figs 3 C, 4 A) longer than 2.08 times pronotum and vertex combined. Forewings (Fig. 3 F) slender, longer than maximal width (2.57: 1).
Male genitalia. Pygofer ventral margin longer than dorsal margin in lateral view (Fig. 4 D), in posterior view (Fig. 4 C) with opening longer than wide, ventral margin with long medioventral process, forked near apical 1 / 2, lateral margins each with a lateroventral process. Anal segment (Fig. 4 C – E) ring-like, with a thick and long anal process at left lateroapical angle, taper the end. Genital styles (Fig. 4 C, D, G) moderately long, hogged, wide at base, tapering at the end, inner margin with a toothed process near the middle. Aedeagus (Fig. 4 H) with phallobase, phallus tubular, curved ventrally, basal part thick, apical part thin, apical part with two slender spinous processes; gonopore located at apex of phallus; phallobase slender and long, arched near basal 1 / 3.
Host plant.
Bamboo.
Distribution.
China (Yunnan Province).
Etymology.
The species name is a combination of the Latin word “ latero - ” and “ spina ”, referring to lateral margins of pygofer, each with a lateroventral process.
