Type species.
Idia albitarsis Macquart, 1846, by original designation.
Diagnosis.
Head. Arista dorsally pectinate, male eyes separated at narrowest point by less than width of ocellar triangle. Thorax. Anepisternum with two upper posterior setae and dense yellow microtomentum; katepisternum with or without yellow microtomentum; thoracic chaetotaxy reduced (presutural acrostichal, dorsocentral and intra-alar absent and postsutural acrostichal and dorsocentral setae restricted to prescutellars). Legs. First tarsomeres always light cream-coloured; fore tibia without submedial posteroventral setae; hind tibia with 2-3 anterodorsal setae as long as tibial diameter, but not forming a distinct row (Fig. 10I View Figure 10 ). Male mid femur with a distal posteroventral row (ctenidium) of closely spaced spine-like setae (Fig. 5J View Figure 5 ; this character is also found in some Stomorhina species, such as S. apta Curran, 1931 and S. malobana (Lehrer, 2007c)). Wing. Cell r4+5 always open. Male terminalia. Tergites 5 and 7+8 connected by a long retractile membrane (Fig. 5I View Figure 5 ), tergite 6 not sclerotised, spiracle 6 present, cerci fused (Figs 2B View Figure 2 , 6A View Figure 6 , 7A, F View Figure 7 , 9A View Figure 9 , 11A View Figure 11 , 12A View Figure 12 ) and sternite 5 divided into three posterior lobes (Figs 3 View Figure 3 , 6F View Figure 6 , 7C, I View Figure 7 , 9F View Figure 9 , 11F View Figure 11 , 12F View Figure 12 ).
Redescription.
♀♂ Head (Figs 5A-D View Figure 5 , 8A-D View Figure 8 , 10A-D View Figure 10 , 13D-I View Figure 13 ). Fronto-orbital plate and parafacial ground colour black, covered with silvery microtomentum; parafacial with a glossy black spot; face ground colour black-brown, covered with silvery microtomentum, facial carina protruding (narrow or broad); lower face margin visible in profile, non-rounded, strongly protruding beyond antennal insertion; pedicel and postpedicel ground colour black-brown; arista pectinate, basally yellow and distally dark brown; vibrissa short and thick, 2-4 supravibrissal setulae adjacent to vibrissa; genal dilation anteriorly glossy black and bare, posteriorly covered with dense yellow microtomentum with hairs, generally with tiny piliferous dots around insertion of each hair; occipital area behind postocular setae with a bare and shiny broad black margin. Thorax (Figs 5G, H, K, L View Figure 5 , 8G, K, J, K View Figure 8 , 10G, H, J, K View Figure 10 , 13A-F View Figure 13 ). General colouration dark olive green with 3 longitudinal dorsal dark vittae, hair insertions with small piliferous dots; pleura covered by dense yellow microtomentum (in different extension degrees); dorsal chaetotaxy reduced, presutural acrostichal, dorsocentral and intra-alar setae absent and postsutural setae reduced to prescutellars and supra-alar; 2 (outer and anterior) post-postpronotal setae present, postalar wall and suprasquamal ridge bare. Wing (Fig. 4E View Figure 4 ). Cell r4+5 always open. Legs (Figs 5J-L View Figure 5 , 8J, K View Figure 8 , 10I-K View Figure 10 ). Femora reddish-yellow; male mid-femur bearing a distal posteroventral row (ctenidium) of closely spaced setae (Fig. 5J View Figure 5 ) that are spine-like in male but not in female; tibiae yellow to brown; first tarsomeres creamy white; first and second hind tarsomeres creamy, almost white. Abdomen (Figs 5E, F, K, L View Figure 5 , 8E, F, J, K View Figure 8 , 10E, F, J, K View Figure 10 ). Longer than broad, extending to wing tip or even further; colour generally yellow-orange and sometimes partly brown. Male terminalia (Figs 1 View Figure 1 - 3 View Figure 3 , 6 View Figure 6 , 7 View Figure 7 , 9 View Figure 9 , 11 View Figure 11 , 12 View Figure 12 ). Sternite 5 divided into three posterior lobes, 2 outer and 1 median. Outer lobes elongated and posteriorly slender or broad, tending to an inward curve (Figs 3 View Figure 3 , 6F View Figure 6 , 7C, I View Figure 7 , 9F View Figure 9 , 11F View Figure 11 , 12F View Figure 12 ), with or without abundant setae of different lengths and thickness; medial lobe forming a broad protuberance of varied shape (Figs 3 View Figure 3 , 6F View Figure 6 , 7C, I View Figure 7 , 9F View Figure 9 , 11F View Figure 11 , 12H View Figure 12 ). Phallus with basi- and distiphallus not fused and connected through a membrane (connection membrane) (Fig. 1A-C View Figure 1 ); epiphallus absent; basiphallus with two anterolateral processes; ventral plate articulate; paraphallus distally globular.
