A sporulating Aspergillus is described from a piece of Eocene amber originating from the Dominican Republic. The Aspergillus most closely resembles a form of the white spored phase of Aspergillus janus Raper and Thom. This is the first report of a fossil species of Aspergillus.

Thefirst fossil species of the caenohalictine bee genus Agapostemon Guérin-Méneville (Halictinae: Caenohalictini:Agapostemonina) is described and figured from a single male preserved in EarlyMiocene (Burdigalian) amber from the Dominican Republic.  Agapostemon (Notagapostemon) luzziiEngel & Breitkreuz, new species, is compared with modern species and isnoteworthy for the absence of metafemoral modifications [in this regardplesiomorphically resembling the West Indian A. kohliellus (Vachal)and A. centratus (Vachal)], form of the head and protibial antennalcleaner, integumental sculpturing, and male terminalia, the latter of which arefortunately exposed and cleared.  Briefcomments are made on the affinity of the species to others in the West Indiesand surrounding regions as well as possible biogeographic implications.

AbstractKathirithamby, 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.

The Myristicaceae is a member of the early diverging angiosperm order Magnoliales; however, the family is poorly represented by fossil collections. We describe Virola dominicana sp. nov. (Myristicaceae), the first record of fossilized Myristicaceae flowers, from mid-Tertiary (45–15 million years ago) Dominican amber. The description is based on 24 male flowers in 17 pieces of amber, thus providing some indication of intraspecific variation, including a two-tepaled flower. Diagnostic characters of the new species are the long-simple or few-branched trichomes on the perianth margins, the small pollen grains, and a short staminal column. These fossils also show co-occurring insects, some of which could be Virola pollinators. It is speculated that V. dominicana disappeared from Hispaniola during the Pliocene–Pleistocene cooling events leaving no native members of the Myristicaceae in this region today. Additionally, these fossils demonstrate that Myristicaceae was present in the Western Hemisphere during the mid-Tertiary.
