Ochreriades

This taxon has been considered the sister lineage "to a clade consisting of the “core” Osmiini, the tribe Megachilini and the genera Pseudoheriades and Afroheriades.

"[1] Over the past decade, phylogenetic analyses have been able to demonstrate that the genus Ochreriades is not closely related to other osmiines or to any other tribe but rather constitutes a unique lineage within the subfamily Megachilinae.

A molecular analysis of the tribe Osmiini concluded similarly that Ochreriades is only distantly related to other osmiines.

[1] The likely explanation for the slender, elongate body shape of Ochreriades is an adaptation to nesting in narrow openings, such as abandoned insect burrows or plant stems.

While the cell partitions exclusively consist of hardened mud, large pebbles are incorporated into the external surface of the nest plug.
