Revision of the Oriental species of the Bengalia peuhi speciesgroup (Diptera, Calliphoridae) Rognes, Knut Zootaxa 2009 2009-10-08 2251 1 1 76 8B6MK Feng & Wei, 1998 Feng & Wei 1998 [180,575,808,835] Insecta Calliphoridae Bengalia Animalia Diptera 30 31 Arthropoda species fani   Figs. 54–63, 176, 189, 201.     Holotypemale, China( Guizhou Province, Anshun, Ganputree farm) ( CDPCAG), by original designation. For details see Type material below.   Bengalia fani Feng & Wei inFeng et al., 1998: 1378, figs. 2820Jv (ST5 flap), 2820L1 (genital capsule in profile view), 2820R (distiphallus in dorsal view). Holotypemale, by original designation, China( Guizhou) ( CDPCAG). Examined.   Diagnosis. Male. Length: 10–12mm. Frons at vertex / head width ratio: 0.363 –0.375, mean 0.368 (n=4). Easily recognised in the male sex by the presence of 2–3 proclinate orbital setae (the hindmost one directed a little laterally) on each side in front of the reclinate prevertical seta. Lunula bare. Anepimeron with a tuft of 10–25 long black thin setae on upper part of posterior half. Fore tibia with two very closely set ventral rows of small spine-like setae of same size in basal half ( Fig. 176). Mid tibia without fringe distally, any prolonged setae shorter than tibial diameter. Hind tibia with an anteroventral fringe of long setae on about distal half. The fringe varies in density, and usually extends on the posteroventral side. Femora are very dark, except sometimes the front one. Abdomen rather dark and the black marginal bands occupy about the hindmost third of the tergites. The anterior yellow parts of the tergites very dark in some lights and covered with microtomentum giving a shifting pattern. ST5 flap ( Fig. 60) about as long as broad, a deep distal excavation present, lateral edges curved but roughly parallel. Cerci strongly curved in profile view ( Fig. 59). The surstyli placed rather low on the epandrium ( Fig. 59). Distiphallus with an extremely prolonged distal half. Antler narrow and pointed. Lateral finger very long and denticulate on more than distal half. Internal hypophallic lobes very strongly converging, almost touching midventrally, distally widening out and transforming into two broad strongly sclerotised ventral bands which continue almost to the tip of the distiphallus. The distance between the bands increases towards the middle and then decreases again. External hypophallic lobe folded distally, presenting a forward-facing wall. Ventral finger sharply triangular, projecting and pointed. Vertical sclerotised sheet fused with mid-dorsal wall forming a lateral sheet carrying the antlers and lateral fingers. Upper lip shaped like a transverse oval. Characteristic structures are present encircling the ejaculatory opening ( Figs. 56, 61, 62). The figure in Feng et al. (1998: 1379, fig. 2820L1) shows the antler and lateral finger both to project ventrally on one side of the distiphallus. This was also the condition of the holotypewhen I received it for examination. This is an artifact caused by the dried condition of the distiphallus.  Female. Length: 10.5– 12mm(n=2). Frons at vertex / head width ratio: 0.371 –0.375, mean 0.373 (n=2). ST2–4 each with a pair of strong marginal setae, with some short black ground setae along hind margin and with yellow ground setulae on disc. ST3 and ST4 also with black ground vestiture in broad bands along sides. ST5 much longer than broad at base, without strong marginal setae, with black ground setae all over. ST3 shorter than other sternites, which are of about the same length.   Description.An English translation of the Chinese original description is given in Appendix 1.   Distribution. China( Guizhou, Yunnan).   Type material.  Bengalia fani Feng & Wei in Feng et al., 1998.  Holotypemale, in CDPCAG, labelled (1) “ Centrefor Disease Prevention and Control of Anshun City, Guizhou/ Ganpu Tree Farm,  1200m/ Wei Lianmeng et al. leg. /  14 May 1985” [in Chinese, print on white label] ( Fig. 63); (2) “C032 … [Chinese name for  B. fani] /  Bengalia faniFeng/ etWei, 1996” [print on white label]; (3) “ ♂/ Holotype” [handwritten on red label].
