A revision of the genus Extenuipalpus Reck, 1959 (Trombidiformes: Tetranychoidea: Tenuipalpidae), with description of a new species.

Extenuipalpus is reviewed, covering its taxonomic history, a new genus diagnosis, body and leg chaetotaxy, and redescriptions of the three previously known species E. niekerkae (Meyer, 1979), E. quadrisetosus (Lawrence, 1940) and E.

Checklist of decapod crustaceans from the coast of the So Paulo state (Brazil) supported by integrative molecular and morphological data: V. Dendrobranchiata and Pleocyemata [Achelata, Astacidea, Axiidea, Caridea (Alpheoidea and Processoidea excluded), Gebiidea, Stenopodidea].

This checklist is the fifth and last compilation on the decapod crustaceans reported to So Paulo (Brazil) coastal area, resulting from long-term multidisciplinary projects, which combined morphological analyses and molecular techniques. The current research includes 75 decapod species, herein referred as shrimps/lobsters-like (shrimps, ghost-shrimps, lobsters, and related groups), reported to So Paulo coastal area. These species occur in marine, estuarine, and amphidromous habitats and are classified into 21 families as follow: Aristeidae (2 spp.

New Species of Entypus (Hymenoptera: Pompilidae) and notes on the natural history of some Atlantic Forest spider wasps.

We describe the new species Entypus renata, sp. nov., from the Brazilian Atlantic Forest and report on its host.

Male terminalia morphology of sixteen species of the Drosophila saltans group Sturtevant (Diptera, Drosophilidae).

Male terminalia in insects with internal fertilization evolve more rapidly than other structures. The aedeagus is the most variable structure, making it a valuable diagnostic feature to distinguish species. The saltans group Sturtevant of Drosophila Fall contains sibling species, that can be distinguished by their aedeagi.
