Saussure, 1856
Species Guides
2Hypalastoroides is a of potter wasps (Eumeninae) established by Saussure in 1856. The genus is predominantly Neotropical in distribution, with some extending into the Nearctic region and Andean elevations. It is distinguished from other New World eumenine genera by the diagnostic second submarginal in the forewing. The genus comprises approximately 30 described species organized into three subgenera: Hypalastoroides, Larastoroides, and Ortalastoroides.

Identification
Hypalastoroides can be distinguished from other New World potter wasp by the presence of a (stalked) second submarginal in the forewing—a wing venation character unique among regional eumenines. The genus contains three subgenera distinguished by morphological features: Hypalastoroides (the nominate subgenus), Larastoroides, and Ortalastoroides.

Subgeneric classification
The is divided into three subgenera: Hypalastoroides (19 ), Larastoroides (2 species: H. costaricensis, H. ecuadoriensis), and Ortalastoroides (7 species). The subgenera were established based on morphological differentiation, though their phylogenetic relationships remain to be fully resolved.
Taxonomic history
The was revised by Giordani Soika in 1982, who provided the most comprehensive treatment of -level . The placement has varied between Vespidae and Eumenidae in different classification systems, reflecting ongoing debate about versus family rank for potter wasps.
