New species of the genus Paravibrissina Shima (Diptera: Tachinidae) from Southeast Asia and South Pacific Author Shima, Hiroshi Author Tachi, Takuji text Zootaxa 2008 1870 43 60 journal article 10.5281/zenodo.183935 161844b2-8d52-4f70-b36b-766af8bde431 1175-5326 183935 Paravibrissina aurigera sp. nov. Figs. 9 , 27 , 31–32 . Recognition. This species is distinct in lacking a row of black setulae on the occiput. The female terminalia resemble those of S. adiscalis in having a very short 8th abdominal tergum. Eggs bear distinct reticulation on the chorion surface. Description. Female. Head with dense yellow pollinosity, occiput yellowish white; antenna mainly dark brown to black, with pedicel weakly reddish brown and base of 1st flagellomere narrowly reddish yellow; palpus reddish brown, darkened on apical 1/2. Vertex about 2/9 of head width; interfrontal area only slightly widened anteriorly, about 1/3 as wide as fronto-orbital plate at middle; parafacial well narrowed below, about as wide as 1st flagellomere at middle height; gena about 1/5 of eye height, with occipital dilation on its lower and anterior 1/3; facial ridge only weakly bulged. Inner vertical seta about 3/5 as long as eye height; outer vertical seta absent; ocellar seta absent; 2 reclinate orbital setae, anterior seta slightly longer than posterior one and about 2/3 as long as inner vertical seta; 2 proclinate orbital setae subequal in length to each other and to inner vertical seta; 5 frontal setae, lowest seta nearly level with base of arista; fronto-orbital plate with only several fine and short hairs; facial ridge with strong downcurved setae on lower 3/5; gena with several fine short hairs; upper occiput with only 1–2 fine black hairs. Antenna falling only slightly short of lower margin of face; 1st flagellomere about 3.5 times as long as pedicel; arista thickened on basal 1/3. Palpus about 2/3 as long as pedicel and 1st flagellomere combined. Eye with dense long hairs. Thorax with dense yellow pollinosity, dorsum with 4 rather broad longitudinal black vittae; scutellum with golden yellow pollinosity. Middle seta of 3 basal postpronotal setae slightly set forward; 3 postsutural dorsocentral setae; 2 katepisternal setae; apical scutellar setae fine and parallel to each other; distance between bases of two subapical scutellar setae slightly less than that between bases of basal and subapical setae of corresponding side; 2 lateral scutellar setae, only slightly shorter than subapical seta. Wing hyaline, well tinged with pale yellowish brown basally; tegula black, basicosta reddish yellow; lower calypter pale yellowish brown. Second costal sector about 1/2 as long as 3rd and subequal in length to 4th; bend of vein M about 3 times closer to wing margin than to r-m crossvein. Legs blackish brown; pulvilli pale brownish. Fore tibia with 2 posterior setae; mid tibia with 2 anterodorsal, 2 posterodorsal and 1 ventral setae; hind tibia with 3 preapical dorsal setae, anterodorsal one short and fine; claws and pulvilli shorter than 5th tarsomeres. Abdomen dark brown in ground color, with dense yellowish pollinosity on entire dorsum except syntergum 1+2, the pollinosity shifting in appearance with direction of light; venter with thin yellowish white pollinosity. Hairs on dorsum rather dense short fine and suberect, stronger on mid dorsal area, on venter fine and longer; syntergum 1+2 with 2 median marginal setae; 3rd tergum with 2 median discal and 2 strong median marginal setae; 4th tergum with 2 median discal and a row of strong marginal setae; 5th tergum with 2 discal and a row of marginal setae. Female terminalia: 6th tergum of small square hemitergites, with a few long and strong hairs on posterior portion; 7th tergum of small elongate hemitergites, with 2 long hairs marginally; 8th tergum very short, broadly divided dorsally and fused with each other on ventral portion; epiproct absent. Male. Unknown. Body length. 6.8mm . Holotype . Female, 25km NW of Rougainville, Espirito Santo Is., New Hebrides [ Vanuatu ], 8–11.ii.1978 , H. Shima (BPBM). Distribution. Vanuatu . Etymology.
