Baeoentedon virgatus Wang, Huang & Polaszek sp. nov. (Figs 20–24) Type material. Holotype female (body on card, antenna and fore wing on slide). China: Hainan Isl.[Island], Qiongshan Co.[County], Volcano Park, 5 July 1998 (coll. Chao-Dong Zhu) (NHM). Female. Body length 0.67 mm. Colour. Body metallic blue-black to blue-brown (Fig. 20). Antenna brown to dark brown (Fig. 21). Fore wing hyaline, with a longitudinal brown to dark brown stripe from stigmal vein to posterior margin of wing (Fig. 22). Legs dark brown, except third segment of hind tarsus pale. Ovipositor brown to dark brown. Head. Head transverse, slightly wider than mesosoma. Antenna (Fig. 21) with 2 anelli, both wider than long; scape 4.11 × as long as wide; pedicel large, 1.48 × as long as wide, distinctly longer than each flagellar segment, except equal in length to C 3 (relative lengths: 59: 22: 27: 20: 59); flagellum short, single funicle segment wider than long (22: 39); relative lengths of claval segments: 27: 20: 59, widths 47: 43: 26, C 3 conically produced at apex into a spine, conic-ovate, approximately equal in length to pedicel (59.44: 58.60); flagellar segments with relatively long setae. Mesosoma. Mesoscutum with areolate-meshed reticulation and with a pair of short and fine setae; scutellum with meshed engraved reticulation and with a pair of setae. Fore wing (Fig. 22) broad, 1.87 × as long as wide, basal cell mostly asetose; marginal fringe 0.13 × as long as width of wing disc; marginal vein with 6 long setae along anterior margin and with a long seta at base of parastigma (Fig. 23); stigmal vein with a slender neck and expanded apex, 4 sensilla arranged in a longitudinal row (Fig. 24); postmarginal vein present but shorter than stigmal vein (Fig. 24). Metasoma. Gaster about as long as mesosoma. T 7 small. Ovipositor not projecting beyond apex of metasoma. Male. Unknown. Host. Unknown. Distribution. China (Hainan: Qiongshan). Etymology. The species name is derived from the Latin, virgatus = striped, referring to the longitudinal brown to dark brown stripe extending from the stigmal vein to the posterior margin of the fore wing. Diagnosis. Baeoentedon virgatus sp. nov. is distinguished from other species of Baeoentedon by the following: fore wing with a longitudinal brown to dark brown stripe from stigmal vein to hind margin of wing (Figs 20, 22); body metallic brown-black to blue-black (Fig. 20); antenna brown to dark brown (Fig. 21); and mesh shape of mesoscutum mostly areolate (Fig. 20), different from the rather elongate meshes in both B. balios (Fig. 2) and B. bouceki (Fig. 15). |
