Uma espécie nova de Schwarzula da Amazônia (Hymenoptera, Apidae, Meliponini)

Schwarzula coccidophila sp. nov., a tiny Amazonian stingless bee, that attends scale insects (Cryptostigma Ferris, 1922, Coccidae) in its nest, is described. It is distinguished from Schwarzula timida (Silvestri, 1902), the only other species of the genus, mainly by the malar area longer than diameter of 3rd flagellomere, and the denser plumose pilosity. Additional records of S. timida is presented.

Leptoconops nosopheris sp. n. (Diptera: Ceratopogonidae) and Paleotrypanosoma burmanicus gen. n., sp. n. (Kinetoplastida: Trypanosomatidae), a biting midge - trypanosome vector association from the Early Cretaceous

Leptoconops nosopheris sp. n. (Diptera: Ceratopogonidae) is described from a blood-filled female biting midge in Early Cretaceous Burmese amber. The new species is characterized by a very elongate terminal flagellomere, elongate cerci, and an indistinct spur on the metatibia. This biting midge contained digenetic trypanosomes (Kinetoplastida: Trypanosomatidae) in its alimentary tract and salivary glands. These trypanosomes are described as Paleotrypanosoma burmanicus gen. n., sp. n., which represents the first fossil record of a Trypanosoma generic lineage.
