Kathirithamby, J. & Grimaldi, D.: Remarkable stasis in some Lower Tertiary parasitoids: descriptions, new records, and review of Strepsiptera in the Oligo-Miocene amber of the Dominican Republic. Ent. scand. 24: 31-41. Copenhagen, Denmark. April 1993. ISSN 0013-8711. 25-30 million years of parasite stasis is recorded in amber from the Dominican Republic, by the finding of a species of strepsipteran morphologically indistinguishable from Bohartilla melagognatha Kinzelbach, 1969 (Bohartillidae), and two species very close to Caenocholax fenyesi (Pierce 1909) (Myrmecolacidae). A new record is made of a species previously described from Dominican amber, Myrmecolax glaesi Kinzelbach, 1983. The history of the Tertiary strepsipteran fauna is discussed. Minimal ages of taxa are extrapolated based on these amber and other fossils, higher-level cladistic relationships, and fossil dating of major host groups. These new findings are consistent with Kinzelbach's hypotheses of an ancient, Lower Cretaceous/Jurassic origin of the Strepsiptera.
