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.

Infection Hypha

Triacutus subcuticularis is described as an endoparasite of bdelloid rotifers. The infection hypha does not establish in the visceral tissue but grows in the pseudocoel between the cuticle and the epidermis. In this location the thallus grows and divides repeatedly to produce numerous unicellular assimilative segments which pack the subcuticular space of the living host. After death, each hyphal segment produces one or several filiform extensions which bear solitary one-celled, three-pronged spores at the apex. Infection is initiated by the spore impaling the rotifers in the mouth region.

Modern Species

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.
