Boudinot et al. (2024), Note 1 - We erect the explicit catchall taxon †Incertogaster. We do so in order to recognize that these some species previously placed in Crematogaster are not meaningfully placeable there based on their preserved morphologies, and that another requires renewed attention.
Identification
Distribution
This taxon is known from Rovno amber, Baltic Sea region, Europe (Priabonian, Late Eocene).
Castes
Nomenclature
The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.
- †INCERTOGASTER [incertae sedis in Myrmicinae]
- †Incertogaster Boudinout, in Boudinot et al., 2024: 14. Type-species: †Crematogaster primitiva Radchenko & Dlussky, 2019: 418, by original designation.
Taxonomic History
- †Incertogaster incertae sedis in Myrmicinae: Boudinot, in Boudinot, Bock, et al. 2024: 148.
Taxonomic Notes
Boudinot et al. (2024) choose †Crematogaster primitiva as the type species of this genus as the specimen of †Crematogaster praecursor examined by Emery is likely lost (see, e.g., Boudinot et al. 2016), and as the compression fossils require revised scrutiny and may be placeable in other genera, whether extant or extinct.
