Agrostocynips diastrophi (Ashmead), n. comb.

Ganaspis diastrophi Ashmead 1896: 184–185 .

The original description states ‘Reared from blackberry gall, Diastrophus cuscutaeformis O.S.’ All known species of Agrostocynips are leaf­miner parasitoids ( Diptera: Agromyzidae); it is probable the described specimens (holotype and paratype) emerged from leafminers accompanying the vegetation in which the gall was formed.
