Alysopius Tobias, 1976: 76-77. Type species: Alysopius compressiventris Tobias, 1976 (monobasic and original designation).

Type locality of type species: Moldavia; holotype female in Zoological Institute, Academy of Sciences, St. Petersburg.

Proposed by Tobias (1976) as a genus of Opiinae; treated as a synonym of Diachasma by Fischer (1986: 657). Following synonymy with Diachasma, the type species of Alyopius became a junior, secondary homonym and was renamed Diachasma compressigaster by Fischer (1986: 657).

As in Diachasma, the labrum is broadly exposed, the mandible lacks a basal tooth or lobe, the notauli and mesoscutal midpit are well-developed and the precoxal sulcus is crenulate and deeply impressed, the fore wing stigma is short and deep, 2RS is roughly the same length as 3RSa, and the hind wing RS and m-cu are present. The female metasoma is strongly laterally compressed for most of its length.

Any revision of Diachasma will need to consider the relationships of the various disparate groups presently included; the relationships of compressigaster to other species of Diachasma are unexplored. See the Diachasma page and Shirley et al. (2014).

This page was assembled by Bob Wharton and Danielle Restuccia. It is part of a review of the genera of World Opiinae, conducted at Texas A&M University. We are particularly grateful to Xanthe Shirley, Andrew Ly, Patricia Mullins, Trent Hawkins, Lauren Ward, Cheryl Hyde, Karl Roeder, and Andrea Walker, who did nearly all of the imaging (together with Danielle) for this project. Matt Yoder and Istvan Miko provided guidance on databasing issues associated with our use of mx and HAO respectively. This project would not have been possible without the kindness of many curators at museums throughout the world who gave generously of their time to Bob Wharton and his students.
