( Figs 20–26View FIGURES 20–26, 35, 36View FIGURES 31–36)

Female macroptera ( Fig. 35View FIGURES 31–36). Head and thorax dark brown; abdominal segments I–VIII pale brown, IX brown, tube dark brown with extreme base paler; all femora brown, tibiae and tarsi yellow; antennal segments I–III brown except for segment III yellow at basal half, segments IV–VIII dark brown; wings slightly shaded grey.

Head ( Fig. 20View FIGURES 20–26) approximately 0.85 times as long as broad; dorsal surface with transverse anastomosing striae except for polygonal reticulation in ocellar region; cheeks with 3–4 pairs of setae and weakly widened towards base; eyes approximately half of head length; postocular setae distinctly shorter than eyes, expanded apically; ocelli well developed, interocellar setae as long as postocellar setae and both pointed apically; postocellar setae as long as diameter of hind ocellus. Antennae 8-segmented ( Fig. 26View FIGURES 20–26), approximately 2.5 times as long as head; segments II–V sculptured; segments III and IV with 1+1 and 1+2 +1 sense cones respectively; segment VIII constricted at base. Mouth-cone short and pointed.

Pronotum ( Fig. 21View FIGURES 20–26) dorsal surface covered with irregular sculpture entirely, notopleural sutures complete; five pairs of major setae well developed and expanded apically, am as long as aa. Mesonotum with transverse anastomosing striae, anterior half with transverse sculpture lines bearing short microtrichia ( Fig. 23View FIGURES 20–26). Metanotum with narrow spaced longitudinal anastomosing striae ( Fig. 23View FIGURES 20–26), median setae moderately long and acute. Basantra present; mesopresternum eroded medially and divided into two lateral triangles with transverse sculpture ( Fig. 22View FIGURES 20–26). Fore tarsal tooth absent. Fore wing slightly constricted at middle, usually with 6 duplicated cilia; subbasal wing setae well developed and expanded apically, S1 slightly shorter than S2, S3 longest and more than 2.5 times as long as S2.

Pelta hat-shaped ( Fig. 24View FIGURES 20–26) with reticulation and slender lateral lobes, a pair of campaniform sensilla present laterally; abdominal tergites with ciliate microtrichia on lines of sculpture laterally and transversely reticulate medially ( Fig. 25View FIGURES 20–26); tergites II–VII each with two pairs of sigmoid wing retaining setae, anterior pair weaker than posterior pair; tergite IX setae S1 slightly longer than S2, with apices blunt, S3 longest, almost as long as tube. Tube slightly shorter than head; anal setae subequal to tube in length.

Measurements (holotype female in microns). Distended body length 1510. Head length 145, width 153; eyes length 70; postocular setae length 42; diameter of anterior (posterior) ocelli 15; postocellar setae length 15. Antennae length 295, segments I–VIII length (width) as follows: 26 (32); 33 (28); 40 (25); 42 (26); 45 (22); 41 (18); 38 (16); 30 (12). Pronotum median length 120, width across median part 220; length of major setae: am 24, aa 23, ml 39, pa 42, epim 51. Fore wing length 585, sub-basal setae S1–S3 length: 34, 38, 100. Metanotum median setae 24. Abdominal tergite IX S1setae length 60, S2 setae length 50, S3 setae length 113. Tube length 110, width at base 55, at apex 24; anal setae length 120.

Male. Macroptera ( Fig. 36View FIGURES 31–36). Similar in colour and structure to female, but smaller, abdominal tergite IX setae S2 approximately 2.5 times as long as S1, pointed apically.

Measurements (paratype male in microns). Distended body length 1400. Head length 145, width 148; eyes length 68; postocular setae length 45; diameter of anterior (posterior) ocelli 14; postocellar setae length 14. Antennae length 277, segments I–VIII length (width) as follows: 23 (33); 31 (30); 38 (31); 41 (27); 44 (22); 38 (18); 33 (18); 29 (11). Pronotum median length 120, width across median part 210; length of major setae: am 25, aa 24, ml 38, pa 43, epim 55. Fore wing length 540, sub-basal setae S1–S3 length: 30, 35, 85. Metanotum median setae 27. Abdominal tergite IX S1setae length 65, S2 setae length 26, S3 setae length 120. Tube length 100, width at base 50, at apex 25; anal setae length approximately 100.

Material examined. Holotype female, CHINA, Hainan: Danzhou City, Danzhou Tropical Botanical Garden (19°30'48''N, 109°30'12''E), from dry sheaths of bamboo, 22.x.2017 (Chao Zhao).GoogleMaps 

Paratypes. 11 females and 5 males, collected with holotypeGoogleMaps  .

Etymology. Specific epithet from Latin “sculpta” which means sculptured, and refers to the body surface of new species is covered with various sculpture.

Distribution. China (Hainan).

Remarks. This new species is similar to B. varia  in appearance and body colour, but it can be readily distinguished from the latter by the following diagnostic characters: (1) antennal segments I–VIII brown except segment III yellow at basal half, while segment III clear yellow in B. varia  ; (2) pronotum with irregular sculpture entirely (vs. pronotum almost smooth in B. varia  ); (3) metanotum with narrow spaced longitudinal anastomosing striae (vs. metanotum with polygonal reticulation in B. varia  ); (4) abdominal tergites with transversely reticulate medially (vs. tergites with smooth medially in B. varia  ).
