description: Dinera guangxiensis sp. nov.
(Figs. 3–4, 12–16)
Diagnosis. Antenna reddish brown except apical 4/5 of flagellomere 1 black, thorax with longitudinal black inner vittae merged on postsutural scutum; abdominal tergites 3 and 4 each with a black trapezoidal marking on apical 4/ 5, and without discal setae.
Description. Body length about 12.0–15.0 mm.
Male. Head black in ground color, gena reddish brown, with grayish white pruinosity; frontal vitta dark brown; lunula brown; flagellomere 1 black on apical 4/5, its basal 1/5 and pedicel and scape reddish brown and arista dark brown to reddish brown; palpus reddish yellow. Frons at narrowest point 0.1–0.11 of head width; frontal vitta widened anteriorly, 1–1.5 times as wide as fronto-orbital plate at middle; parafacial about twice as wide as flagellomere 1 in profile; genal height about 0.4 times as high as eye height; facial carina high and arched in lateral view. Fronto-orbital plate and parafacial bare; 15 to 16 inclinate frontal setae, the strongest one about as long as inner vertical seta; inner vertical seta 0.4–0.5 times as long as eye height; outer vertical seta absent; ocellar seta and postocellar seta strong, ocellar seta 1.2–1.3 times as long as inner vertical seta. Flagellomere 1 3–4 times as long as wide, 2–2.5 times as long as pedicel; pedicel with two long setae, lower one slightly longer and about as long as antenna; antenna falling short of lower margin of face by 0.8–1.0 length of flagellomere 1; arista including plumosity 2.0–2.2 times as wide as flagellomere 1; palpus about 7/9 as long as vibrissa; prementum 5–6 times as long as wide.
Thorax black in ground color, with grayish white pruinosity; scutum with 5 black longitudinal vittae, outer vitta about as wide as pruinose portion between inner and outer vittae on presutural area, inner vittae extending to posterior half of postsutural scutum and merged; scutellum black, with grayish white pruinosity on outer margin; pleura black, with grayish white pruinosity. Prosternum 1.5–2.0 times as long as wide; 4 postpronotal setae, 3 basal setae arranged in a triangle, 2 presutural and 2–3 postsutural acrostichal setae; 3 presutural and 4 postsutural dorsocentral setae; 2–3 postsutural intra-alar setae; 3 supra-alar setae, prealar seta about 0.5 times as long as the first intra-alar seta; 3 katepisternal setae; 1 anepimeral seta thin, extending to posterior margin of upper calypter; apical scutellar seta about 1.5 times as long as scutellum, shorter than subapical scutellar seta; 2–4 discal scutellar setae. Wing hyaline, slightly tinged with pale brownish; tegula black; basicosta reddish yellow on basal half and dark on apex; lower calypter pale yellowish white; halter reddish yellow. Costal spine indistinct; base of vein R4+5 with 3–4 fine hairs on dorsal and ventral surfaces; relative length of costal sections 2nd, 3rd and 4th approximately as 4:6:3; vein M from dm-cu crossvein to its bend about 3 times distance between the bend and wing margin. Legs black; pulvilli pale brown. Fore tarsi distinctly longer than head height; fore claws and pulvilli longer than 5th tarsomere; fore tibia with a row of short anterodorsal setae on basal 3/5 and 2 posterior setae; mid tibia with 1–2 anterodorsal and 2–3 posterior setae, usually without, sometimes with a short ventral seta; hind tibia with 3–4 anterodorsal, 3–4 posterodorsal and 1–2 ventral setae.
Abdomen ovate, black in ground color, with grayish white pruinosity on entire dorsum; tergites 3 and 4 each with a black trapezoidal marking on apical 4/5; recumbent seta-like black hairs on tergites. Syntergite 1+2 almost excavated to posterior margin, with 1 pair of median marginal and 1–2 pairs of lateral marginal setae; tergite 3 with 1 pair of median marginal and 2–3 pairs of lateral marginal setae, without discal setae; tergite 4 with a row of strong marginal setae, without discal setae; tergite 5 with a row of strong marginal setae and some irregularly set discal setae. Sternite 5 quadrangular, posterior lobe weakly pointed at apex in ventral view, V-shaped median cleft deep and wide. Male terminalia. Cerci short, wide at base and narrowed to apex on distal half in caudal view; surstylus wide and rounded apically; surstylus longer than cerci in lateral view, pregonite flat and curved ventrally; postgonite shorter than basiphallus; distiphallus long, sclerotized basal part slightly shorter than membranous apical part.
Female. Vertex about 2/5 head width; outer vertical seta about 0.6 times as long as inner vertical seta, 2 proclinate orbital setae, and 1 reclinate upper orbital seta; genal height 0.5–0.6 times as long as eye height; claws and pulvilli shorter than 5th tarsomere; mid tibia with 1 strong ventral seta; abdomen wide ovate.
Type material. Holotype 3, CHINA, Guangxi: Dayaoshan Mountain (24°10ʹN 110°23ʹE), 630–1200 m, Jinxiu, 13–18.v.2011, Q. Wang. Paratypes. CHINA: 6 males, 2 females, same locality and date as holotype, C.-T. Zhang, C. Fu, Q. Wang (SYNU).
Etymology. Specific epithet is named for the province of the type locality, Guangxi.
Distribution. China (Guangxi).
Remarks. This species is very similar to D. takanoi (Mesnil), but differs from the latter in having long and dark brown flagellomere 1 except base brown, flagellomere 1 3–4 times as long as wide, palpus distinctly longer than antenna, abdomen dark brown, tergite 4 without discal seta.
