Vieira Navas 1913

Vieira (Penny 2002: 205���206, Figs 129���131; Tauber 2006, 2007; Tauber et al. 2006; Sosa & Tauber 2017; here Fig. 23). Size: Body large and stout to relatively small and slender; forewing length 11.6���26.0 mm; males and females of similar size. Coloration: Cream with bold, black body markings; antennal flagellum dark basally. Wings: Not narrowed; ratio of forewing length to width = 2.5���2.6: 1; costal area of forewing with patch of splayed crossveins, with dark markings (splaying very moderate in V. elegans (Gu��rin M��neville); forewing and hindwing with dark patches; veins in dark patches also dark, other veins mostly pale. Tarsal claws: Basal dilation present. Abdomen: Setae relatively long, moderate density. Male: Dorsal apodeme of T 9+e sinuous, with proximal section extending downward and well into A8; S8+9 fused with prominent suture; microtholi on S3���S8; gonarcus without gonocornu or frontal plate; mediuncus with or without frontal setae; parameres large, quadrate, closely attached to gonaracus via stiff membrane. Female: Abdominal tergites without mesal suture; dorsum of T 9+e with or without deep mesal invagination; praegenitale absent. In summary, Vieira is the only New World belonopterygine genus having the following suite of features: a robust, pale body with bold, black markings, wings with large dark markings, costal area of forewing with a series of splayed costal crossveins within a dark marking; males with quadrate parameres that are closely associated with the gonarcus, and females lacking a praegenitale.
