Ipsiura amaurotica ( Linsenmaier, 1997) : present paper: stat. resurr.

Material examined. Holotype of Neochrysis amaurotica , ♂: Brasil Obidos 1.1905 [Ducke] / 397 / ♂ Neochrysis amaurotica Lins. Linsenmaier det. 1985 / ♂ Ipsiura tropicalis amaurotica det. Linsenmaier 1995 / NML_ENT GBIF_ Chr 0013456 ( NMLU).

Neochrysis amaurotica was synonymized by Kimsey & Bohart (1991) with Ipsiura tropicalis Bohart, 1985 , without type examination, and later revalidated as a subspecies by Linsenmaier (1997), who provided a diagnosis and a line drawing to support this action. Lucena et al. (2024) ignored this revalidation and again considered it a synonym of I. tropicalis Bohart, 1985 . We examined the holotype of Neochrysis amaurotica , which differs from I. tropicalis in metasomal sculpture and the structure of the third tergum as described and illustrated by Linsenmaier (1997). The main differences between the two species are the large and spaced punctures and the elongate postpit area of the third tergum in N. amaurotica ( Fig. 12D ) vs dense and small punctures on the mesosoma and a short postpit area in I. tropicalis (see Bohart 1985: Fig. 8 ). Both species were described based on males; therefore, the observed differences cannot be attributed to sexual dimorphism. We consider these differences to be sufficient to recognise Neochrysis amaurotica ( Linsenmaier, 1985) stat. resurr. as a valid species. The female specimen illustrated by Lucena et al. (2016: Figs 179–181) corresponds to I. amaurotica ; records from Brazil should be re-evaluated to confirm the occurrence of I. tropicalis in the country.
