Description of Blepharoneura View in CoL View at ENA

Body nonmetallic, usually predominantly yellow, often with brown markings, occasionally predominantly brown.

Head: Frons setulose, with 2 orbital setae and usually 2 frontal setae. Ocellar and postocellar setae well developed. Frontal vitta usually orange, red or brown with narrow yellow area medially ( Fig. 1 View FIGURE 1 ). Facial carina weak. Vibrissa absent. Antenna moderately long but usually not reaching ventral margin of face. Arista long pubescent to short plumose. Prementum elongate and strongly convex. Labella with sclerotized ridges or spicules (modified pseudotracheal ring tips; often not exposed in dry specimens).

Thorax: Yellow to orange, often with brown markings, particularly on mesonotum, in a few species of femoralis group predominantly brown ( Figs. 90–108 View FIGURES 90–93 View FIGURES 94–97 View FIGURES 98–101 View FIGURES 102–105 View FIGURES 106–108 ). Scutum posteriorly usually with pair of brown markings or single band or larger mark, often with 2–4 vittae, especially anteriorly. 1–2 postpronotal setae (second seta often varies intraspecifically), 2 notopleural, 1 presutural and 1 postsutural postalar, 1 intra-alar, 1 postalar, often 1 intra-postalar, 1 dorsocentral, 1 acrostichal, 3 scutellar, 3 anepisternal (1 on upper fourth just anterior to phragma), 1 anepimeral, and 1 katepisternal setae.

Wing: Vein Sc subapically anteriorly turned at 80–90° angle. Veins R 1, R 4+5, Cu 1 and base of vein Cu setulose dorsally. Crossvein r-m near or distal to midlength of cell dm (measured along vein M). Cell bcu with elongate posterodistal lobe. Pattern usually predominantly brown with hyaline spots and marginal incisions, sometimes on apical third with hyaline bands; cells dm and cu 1 sometimes with large hyaline area or occasionally 1–2 hyaline bands ( Figs. 2–81 View FIGURES 2–5 View FIGURES 6–15 View FIGURES 16–25 View FIGURES 26–35 View FIGURES 36–45 View FIGURES 46–55 View FIGURES 56–65 View FIGURES 76–83 ).

Abdomen: Occasionally entirely yellow, but usually yellow with brown spots or reticulate pattern to predominantly brown with medial yellow vitta or row of spots ( Figs. 1 View FIGURE 1 , 113–125 View FIGURES 113–118 View FIGURES 119–125 ).

Female terminalia: Oviscape tapering, subconical to funnel-shaped (short, subconical, brown in femoralis group). Aculeus short, broad (especially in femoralis group), and flat; in femoralis group usually with acute or blunt scales on medial membrane (e.g., Figs. 126–135 View FIGURES 126–135 ); tip in poecilosoma group triangular, with numerous distinct serrations, each associated with internal channel ( Condon & Norrbom 1994, figs. 14–16), in femoralis group truncate to subtriangular, with step-like or digitiform lobes ( Figs. 126–187 View FIGURES 126–135 View FIGURES 136–145 View FIGURES 146–155 View FIGURES 156–164 View FIGURES 165–172 View FIGURES 173–181 View FIGURES 182–187 ). 3 spermathecae ( Figs. 188– 193 View FIGURES 188–195 ), subspherical or occasionally conical, usually with sclerotized neck and/or small to large basal apodeme, surface without denticles.

Male terminalia: Lateral surstylus relatively short ( Figs. 196–203 View FIGURES 196–199 View FIGURES 200–203 ), with epandrium forming near oval in posterior view. Glans with single membranous, non-spiculose, basal lateral lobe; elongate, basal half slender and membranous, distal half strongly sclerotized, cylindrical ( poecilosoma group) or stout and bulbous ( femoralis group). Proctiger sometimes weakly bilobed ventrally.

Egg ( Figs. 194–195 View FIGURES 188–195 ): Cylindrical ovoid, slightly curved, slightly tapered.
