Synthesis of Brazilian Collembola: an update to the species list

TLDR
The current total number of species found in Brazil is 270, distributed in 19 families and 92 genera, an increase of 71 species and 12 genera in the last 6 years as discussed by the authors.
Abstract
The current total number of species found in Brazil is 270, distributed in 19 families and 92 genera, an increase of 71 species and 12 genera in the last 6 years. The greatest known diversity is found in Rio de Janeiro (132 species), Amazonas (56), Espirito Santo (30) and Sao Paulo (28), while there are no record to seven Brazilian states (Acre, Alagoas, Distrito Federal, Goias, Rio Grande do Norte, Roraima and Tocantins). Distribution of the records clearly defines the areas that urge investments in scientific research and taxonomic survey and reflects the concentration of information in those centers that host the few specialists in Collembola, currently working in Brazil.

Cave Conservation Priority Index to Adopt a Rapid Protection Strategy: A Case Study in Brazilian Atlantic Rain Forest

TL;DR: The use of the CCPi can prevent future losses because it helps assessors to select caves with priorities for conservation which should receive emergency attention in relation to protection, management and conservation actions.

Updated list of Collembola species currently recorded from South Africa.

TL;DR: An updated list of the Collembola species from South Africa is provided and shows that much ongoing work will be required before a reasonably comprehensive and spatially explicit picture of South Africa’s springtail fauna can be provided, which may well exceed 1000 species.

Insect (Hexapoda) diversity in the oceanic archipelago of Fernando de Noronha, Brazil: updated taxonomic checklist and new records

José Albertino Rafael, +53 more
TL;DR: This study more than doubles the knowledge of the entomofauna of the Fernando de Noronha archipelago and provides a baseline for studies on its conservation status and for implementing future environmental management programs.

Hexapod Origins: Monophyletic or Paraphyletic?

TL;DR: It is shown that Collembola, a wingless group traditionally considered as basal to all insects, appears instead to constitute a separate evolutionary lineage that branched much earlier than the separation of many crustaceans and insects and independently adapted to life on land.

A Review of Arthropod Phylogeny: New Data Based on Ribosomal DNA Sequences and Direct Character Optimization

TL;DR: The high level of sequence heterogeneity in the 18S rRNA gene makes placement of certain taxa with “unusual” sequences difficult and underscores the necessity of combining ribosomal gene data with other sources of information.

The Complete Mitochondrial DNA Sequence of the Basal Hexapod Tetrodontophora bielanensis: Evidence for Heteroplasmy and tRNA Translocations

TL;DR: The complete 15,455-nt mitochondrial DNA sequence of the springtail Tetrodontophora bielanensis (Arthropoda, Hexapoda, Collembola), which shows the well-known A+T bias typical of insect mtDNA, and two tRNA translocations were found which were unprecedented among Arthropoda.

Crustacean phylogeny inferred from 18S rDNA

TL;DR: Resolution concerning issues of higher-order crustacean phylogeny remains elusive even after years of thorough morphological and palaeontological scrutiny and there is as yet no consensus regarding even the number of constituent crustaceans.
