Associated to the scholarship:15/19867-0 - Investigating the phylogeny of Tarsoneminae CANESTRINI & Fanzago, 1877 (Acari: Tarsonemidae): use of electronic (LT-SEM) and confocal (CLSM) microscopies on the inclusion of new genera and reinterpretation of characters, BP.PD


Tarsoneminae Canestrini & Fanzago is one of the three subfamilies of Tarsonemidae (Acari: Prostigmata). There is only one phylogenetic study for this subfamily (Lindquist 1986). Since then, new Tarsoneminae genera have been found and described, which makes this initial phylogeny hypothesis outdated. Also, new microscopy technologies have been developed, bringing new comprehension about the morphology of mites. Therefore, it is necessary to investigate the Tarsoneminae phylogeny again, gathering the new taxa in the analysis and using microscope and heuristic methods advanced. This way, the main objective of this proposal is to gather information about the internal and external morphology of all known Tarsoneminae genera, in order to produce a new and improved phylogenetic hypothesis. For this, we aim to study the Tarsoneminae types deposited in the NMNH Mite Collection and other institutions around the world, through loaning. We also intend to analyze morphological characters through phase contrast (PC), differential interference (PC), confocal (CLSM) and low temperature scanning electron (LT-SEM) microscopes. After the morphological analyses, we expect to elaborate better genera diagnosis, when necessary. These activities are planned to be executed at the National Insect & Mite Collection (NIMC), National Museum of Natural History (NMNH) Smithsonian Institution, Washington DC, US; and the Electron and Confocal Microscopy Unit (ECMU), United States Department of Agriculture (USDA), Betsville MD, USA.
