Ipsiura superleucocheila ( Linsenmaier, 1985) was synonymized with I. spiculella Bohart, 1985 . However, the holotype of I. superleucocheila does not share the diagnostic features of I. spiculella but is more closely related to I. leucocheila , as noted by Linsenmaier (1985). I. superleucocheila is more robust, and significantly larger than I. leucocheila , measuring 10–11 mm compared with 6.3–7.1 mm given by Lucena et al. (2016) and 6.5–7.5 mm given by Linsenmaier (1985). The two species share several diagnostic characters, including the shape of the third tergum with four acute apical teeth, a low prepit swelling that slopes gently, a well-developed pit row with small pits and long deep foveae, and a large lateral whitish spot; the cristate metanotum; the transverse frontal carina slightly interrupted medially; the light brown wing membrane; the greenish-blue femora and tibiae; the brownish tarsi with green metabasitarsus; and the profemur without a ventral tooth-like projection or flattened area on the outer surface of the distal margin. The main differences between the two species, besides the robust habitus and the noticeably larger size of I. superleucocheila , include the apical margin of the third tergum, which is roof-like ( Fig. 16C View FIGURE 16 ) with sharper teeth, more so than in other similar species; the more elongate post-pit row ( Fig. 16C View FIGURE 16 ); the shape of the black spots on the second sternum, which are larger and more closely positioned medially, separated by only one third of the width of a black spot ( Fig. 16D View FIGURE 16 ) vs one spot’s width in I. leucocheila . Based on these diagnostic characters, and pending further morphological and molecular analyses, we consider Ipsiura superleucocheila ( Linsenmaier, 1985) stat. resurr. a valid species.
