Type material.
Holotype: China • ♂: Guizhou Province, Weining County, Xueshan Town; 27°4'N, 104°7'E; sweeping, 4 August 2023; Hong-Xing Li leg.; IEGU. Paratypes: China • 8 ♂♂, 12 ♀♀; Guizhou Province, Weining County, Xueshan Town; 27°4'N, 104°7'E; sweeping, 4 August 2023; Hong-Xing Li and Jie Wang leg.; IEGU.
Diagnosis.
The salient features of the new species include: vertex (Fig. 1 A, C) light, without dark brown spots; lateral areas of pronotum (Fig. 1 A, C) with dark brown markings; mesonotum (Fig. 1 A, C) with dark brown markings; forewings (Fig. 1 F) with one large black marking at basal 1 / 3; medioventral process of pygofer (Fig. 2 C, F) forked near apical 1 / 2; dorsolateral margin of aedeagus (Fig. 2 J) with three spinous processes at apical part, ventrolateral margin with four spinous processes of similar length. This species is similar to B. maculata Chen & Li, 2000, but differs from the latter in: (1) forewings MP 1 + 2 fully commingled (forewings MP 1 + 2 commingled at base in B. maculata); (2) apical part of genital styles not forked (apical part of genital styles forked in B. maculata); and (3) apical part of aedeagus with some spinous processes on both sides (apical part of aedeagus with some spinous processes on only one side in B. maculata).
Description.
Measurements. Total length: male 4.6–4.9 mm (N = 9), female 5.0– 5.3 mm (N = 12).
Coloration. General color yellowish-white to black (Fig. 1 A – F). Vertex and frons yellowish-white, rostrum blackish-brown at apex. First segment of antennae yellowish-white at dorsal and ventral sides, lateral sides dark brown, second segment yellowish-white. Eyes reddish-brown. Pronotum yellowish-white, outer sides of lateral carinae with black broad stripes, inner sides with two dark brown round spots. Mesonotum black, lateral margins yellowish-brown, apex of scutellum opalescent. Outer part of tegula black brown, inner part yellowish-white. Forewings milky-white, hyaline, basal 1 / 3 with a dark brown, wide transverse marking. Legs yellowish-white, except coxae of fore and median legs dark brown.
Head and thorax. Vertex (Figs 1 C, 2 A) shorter in middle line than wide at base (1: 1.11), width at apex narrower than at base (1: 1.19), middle part of anterior margin convex, lateral margins widened towards the end, lateral and submedian carinae distinct, Y-shaped carina indistinct. Frons (Figs 1 E, 2 B) longer in middle line than wide at widest portion (about 2.12: 1), widest at apex, median carina simple. Base of postclypeus (Figs 1 E, 2 B) as wide as apex of frons. Antennae (Figs 1 E, 2 B) with first segment longer than wide, shorter than second segment (1: 3.33). Pronotum (Figs 1 C, 2 A) longer than vertex in midline (1.14: 1). Mesonotum (Figs 1 C, 2 A) longer than 1.17 times pronotum and vertex combined. Forewings (Fig. 1 F) slender, longer than maximal width (2.81: 1).
Male genitalia. Pygofer ventral margin distinctly longer than dorsal margin in lateral view (Fig. 2 E), in posterior view (Fig. 2 C) with opening longer than wide, ventral margin with long medioventral process, forked near apical 1 / 2, right branch longer than left one. Anal segment (Fig. 2 C, D) ring-like, with a thick and long anal process at left lateroapical angle, taper the end and bend to the right. Genital styles (Fig. 2 G – I) moderately long, wide at base, tapering at the end, in posterior view asymmetrical, in lateral view apex truncated. Aedeagus (Fig. 2 J) with phallobase, phallus tubular, basal part thick, apical part thin, ventrally curved at basal 1 / 3; dorsolateral margin of apical part with three spinous processes, inner one much longer than the other two, ventrolateral margin with four spinous processes of similar length; gonopore located at apex of phallus, node-like; phallobase slender and long, arched medially.
Host plant.
Bamboo.
Distribution.
China (Guizhou Province).
Etymology.
The species name is a combination of the Latin word “ caudo - ” and “ spina ”, referring to apical part of aedeagus with spinous processes.
