Phylogenetic position of the acariform mites: sensitivity to homology assessment under total evidence
The phylogenetic position of the acariform mites is examined through employing SSU, partial LSU sequences, and morphology from 91 chelicerate extant terminals, and morphological data matrices to evaluate the impact of constraining the analysis on the recovered topology when employing secondary structure as a guide for homology establishment.
Origin and higher-level diversification of acariform mites – evidence from nuclear ribosomal genes, extensive taxon sampling, and secondary structure alignment
The accepted taxonomic classification of Acariformes is updated to reflect the results, which show that a clade comprising early derivative Endeostigmata (Alycidae, Nanorchestidae, Nematalyc Families, and maybe Alicorhagiidae) should be treated as a taxon with the same rank as Sarcoptiformes and Trombidiformes.
New species and new occurrences of Copidognathus (Acari, Halacaridae) from the northern littoral zone of São Paulo State (Brazil)
Seven species from the northern littoral zone of Sao Paulo State (Brazil) are here reported and their descriptions are extended with descriptions of their protonymphs.
Two new species of Agauopsis (Halacaridae, Acari) from Southeastern Brazil
Mites belonging to two new species of Agauopsis (Halacaridae, Acari) were obtained from seaweed, coarse sand and coarse shell debris taken from several sites in Northern Coast of Sao Paulo State.…
A checklist of chiggers from Brazil, including new records (Acari: Trombidiformes: Trombiculidae and Leeuwenhoekiidae)
Abstract A checklist of the family Trombiculidae and Leeuwenhoekiidae is presented, containing 63 species in 30 genera of chiggers from 80 different hosts and 146 localities in Brazil. The type…
Reassessment of the evolutionary relationships within the dog‐faced bats, genus Cynomops (Chiroptera: Molossidae)
The use of mitochondrial genes combined with morphological characters revealed again to be a powerful tool to recover the phylogenetic relationships within Cynomops and demonstrated that the genus is more diverse than previously thought.

To choose the delimitation model that best fit the data, the hypotheses recovered by GMYC, STACEY and morphology and created by merging species recovered by those methods had their marginal likelihood estimated and compared using the Bayes factors.
New records of the genus Whartonia (Acari, Leeuwenhoekiidae) associated with the bat Carollia perspicillata from southeastern Brazil
Two species of mites belonging to the genus Whartonia Ewing, 1944, family Leeuwenhoekiidae (Womersley, 1944), were obtained from Carollia perspicillata (Linnaeus, 1758) bats from mine tunnels in the…

In the present study the instar association was made through an integrative approach including rearing trials and molecular analysis of the cytochrome oxidase I (COI) gene with the Bayesian Generalized Mixed Yule Coalescent (bGMYC) algorithm for species delimitation.
FAMILIAL LEVEL PHYLOGENY OF FREE-LIVING CYCLOPOIDS (COPEPODA), INFERRED FROM PARTIAL 18S RIBOSOMAL DNA
This study is the first familial level phylogenetic analysis of free-living cyclopoid copepods and concludes that the predominantly freshwater Eucyclopinae and Cyclopinae form a strongly supported group, but the relationship between these two subfamilies remains unresolved.
