Neochrysis (Ipsiura) sobrina Linsenmaier, 1985: 474 . Holotype ♀. Brazil: São Paolo (NMLU, examined). Synonym of Ipsiura catamarcae Bohart, 1985 according to Kimsey & Bohart (1991: 509); Lucena et al. (2016, 2024: 35). Reinstated by Linsenmaier (1997: 266).

Neochrysis (Ipsiura) sobrina: Synonym of Ipsiura fritzi Bohart, 1985 syn. nov.: present paper.

Material examined. Holotype of Neochrysis sobrina, ♀: São Paulo Batatas Pereira 17.X.46 / ♀ Type Neochrysis sobrina Lins. Linsenmaier det. 1985 / 400 / NML_ENT GBIF_ Chr 0013486 (NMLU).

Neochrysis sobrina Linsenmaier, 1985 was synonymized by Kimsey & Bohart (1991) with Ipsiura catamarcae Bohart, 1985; however, the type of I. sobrina lacks the diagnostic characters of I. catamarcae, as the post-ocular and metapleural surfaces are fully punctate, rather than polished as in I. catamarcae (Figs 15A, E), the profemur lacks a tooth on the distal margin (Fig. 15E), which is toothed or angled in I. catamarcae, and the metanotum is cristate rather than simply rounded as in I. catamarcae . Conversely, the transversal frontal carina is broad and forms a rounded arc around the anterior ocellus (Fig. 15B), the apical teeth on the third tergum are regularly spaced (Fig. 15C), and the wings are nearly clear (Fig. 15A). This species matches the descriptions and illustrations of I. fritzi Bohart, 1985 as described by Bohart (1985) and Lucena et al. (2016). For this reason, we propose the new synonymy of Neochrysis (Ipsiura) sobrina Linsenmaier, 1985 syn. nov with Ipsiura fritzi Bohart, 1985 .
