The genus Xiphosomella belongs in the subfamily Cremastinae. This genus and Pristomerus differ from other genera of the subfamily in having a distinct thyridium on the second tergite. In Xiphosomella the thyridium is some distance from the base of the second tergite, while in Pristomerus the thyridium is very close to the base. Both genera may or may not have a spine on the under side of the hind femur. Xiphosomella may have an areolet. Most species of Xiphosomella are Neotropic. One species (dubia) has been described from the United States. This paper adds a second species.

Unless otherwise stated, all specimens are in the Townes collection, Ann Arbor, Michigan.
