Genus Helicobia

Helicobia emerged as a monophyletic group in all our analyses, and the taxon has been supported in all available phylogenies (i.e., Giroux et al. 2010; Kutty et al. 2010; Stamper et al. 2012). Six unique autapomorphies supported this genus: (1) ocellar setae very strong, (2) vertical setae very strong, (3) vesica divided into three plates, (4) vesica bulbous medially, (5) vesica with distal hammer-shaped margin or with two lateral processess (Fig. 2f), and (6) female tergite VI with a mid-dorsal line or narrow membranous longitudinal mid-dorsal line. From the seven apomorphies that supported this taxon in the phylogeny of Giroux et al. (2010), only one—the posterior and posteroventral setae unmodified in the male hind tibia—was included here, which was not uniquely derived in this genus, but shared with the outgroup species S. albifrons and W. vigil .
