Description
Male macroptera. Body uniformly brown; antennal segments I–II brown, III–VI yellow but shaded in their clubheads, VII–VIII brown; fore wings uniformly pale; femora and tibiae brown with pale extreme bases and apices, tarsi yellow; abdominal tubercles on segment VI yellow with dark brown in basal 0.2, tubercles on VII–VIII dark brown, tube dark brown; major setae yellowish. Head 2.1 times as long as wide across eyes, projecting in front of eyes, transversely striate; interocellar setae longest, longer than width of one eye, one pair of postocellar setae about as long as diameter of posterior ocellus; eyes developed, about 0.3 of head length, slightly prolonged ventrally, postocular cheek setae shorter than postocular setae; mid-dorsal setae developed, but much shorter than interocellar setae; cheeks with several pairs of minor setae (Figs 16, 37). Maxillary stylets wide apart, retracted into head one third way to posterior margin of eyes (Fig. 16). Antennal segment III length 1.1 times as long as head width across eyes (Fig. 25), III with 2 sensoria, IV with 4, V with 2, VI and VII each with one, these sensoria on III and IV about 2.1 times as long as apical width of segment, segments VI–VII with a short apical, ventral prolongation. Pronotum with irregular sculpture, anterior margin concave, epimeral sutures complete; 2 pair of am, one pair almost as long as aa, epima about as long as half of epim (Figs 16, 26). Metanotal median setae developed, metanotum smooth on anterior third, with weak reticulate sculpture on posterior half (Figs 18, 27). Fore wings broad, with about 40 duplicated cilia. Pelta with reticulate sculpture slightly longitudinal, lateral lobes narrowly joined to median lobe (Figs 31, 27); lateral abdominal tubercles on VI well developed and straight, about 1.9 times as long as length of the segment, tubercles on VII smaller than ones on VIII (Figs 22, 43); tergite IX setae much shorter than tube; tube about 1.4 times as long as head, weakly constricted near apex, laterally with few weak setae. Sternites with an irregular single or double transverse row of discal setae no pore plates. Measurements (holotype male in microns). Body length 6379. Head, length 677; width across eyes 316; head setae length: interocellars 143, postocellars 36, postoculars 62, postocular cheek setae 49, mid-dorsal setae 82, diameter of posterior ocellus 33. Antennal segments III–VIII length (maximum width), 351 (52), 271 (57), 254 (48), 155 (41), 98 (31), 85 (24), sensoria of segment III length 108. Pronotum length (maximum width) 268 (534); setae length, am83, aa86, ml111, epim179, epima84, pa111, pm44. Metanotum median setae length 170. Pelta length (maximum width) 166 (648). Tubercles on tergite VI length 756, little tubercles on VII–VIII length 22, 58; tube length 944. Female macroptera. Similar to male, but without tubercles on abdominal segments VI–VIII, tergite IX with setae S 1 and S 2 similar in length. Measurements (paratype female in microns). Body length 5908. Head, length 624; width across eyes 321; head setae length: interocellars 150, postocellars 49, postoculars 69, postocular cheek setae 55, mid-dorsal setae 81, diameter of posterior ocellus 37. Antennal segments III–VIII length (maximum width), 318 (50), 277 (53), 243 (46), 148 (39), 87 (30), 81 (18), sensoria of segment III length 103. Pronotum length (maximum width) 259 (500); setae length, am85, aa85, ml103, epim184, epima88, pa129, pm49. Metanotal median setae length 177. Pelta length (maximum width) 188 (682). Tergite IX setae S 1 267, S 2 300; tube length 989, anal setae length 249.
Materials Examined
Material examined. Holotype male. CHINA, Zhejiang Prov. (Linan County, Qingliangfeng Mountain, 30.07 °N, 118.51 °E), on dead hanging tree leaves, 4.viii. 2011, L.H.Dang & J.Wen, No. JM 11241 - 2. Paratypes: 8 females3 males, with same data as holotype, Nos. JM 11241 - 1, JM 11241 - 3 – - 11.
Discussion
Remark. This species is somewhat similar to B. carbonarius Haga & Okajima in appearance, with interocellar setae longest and all tibiae brown. But the new species is distinguished by the following characters: postocellar setae as long as or a littler longer than the diameter of posterior ocellus, much shorter than postocular setae and mid-dorsal setae, postocular cheek setae shorter than postocular setae (carbonarius: postocellar setae more than twice as long as diameter of posterior ocellus, much longer than postocular setae and mid-dorsal setae, postocular cheek setae longer than postocular setae), pronotal epima about half as long as epim, epimeral sutures complete (carbonarius: pronotal epima usually much more than half as long as epim, epimeral sutures incomplete), abdominal tubercle on segment VI yellow with dark brown in basal 0.2, small tubercle present on VII (carbonarius: abdominal tubercle on segment VI uniformly dark brown, segment VII without lateral tubercles).
Etymology
Etymology. This species name is composed of two Latin words, “ furvus (= dark, black)” and “ crus (= leg)”, based on all tibiae uniformly dark brown.
