A new species of the genus Szeptyckitheca is described from the Biological Reserve of Serra do Japi, São Paulo State, Brazil. All species of the genus present trochanteral spine on the first and third legs, cephalic chaeta A1 often absent. The presence of spine in all trochanters, chaetal row F in head, and abdominal and antennal segments with long bristles with capitate apex are relevant features that distinguishes the new species from all known species of the genus. A key to the identification of the species of Szeptyckitheca is presented.

A new proposal for taxonomic species description is presented to replace
the traditional descriptive texts. This is an attempt to enhance the
species description rate and to make the description output available to
other scientific disciplines, machine learning, lucid identification
keys, big data analysis and its applications. The method consists in
presenting the description of the overall morphology in a coded matrix,
following a character list with detailed observed conditions for each
character. The method is supposed to be dynamic and open to amendments
and new data addition as they become available. We test the new method
describing five new species of Collembola Symphypleona of the genus
Pararrhopalites as a generalized model and made the coded output
available. We conclude that a coded taxonomic description is an advance
to the traditional taxonomic text, with potential to enhance the global
descriptions rate. The generated data is a dynamic matrix that can be
expanded with any data that becomes available, also it can be easily
used in other fields of science, allowing non-experts to access the data
for phylogenetic, biogeographic, ecological studies and big data
analysis. Furthermore, it is a step forward to a general template to
semi-automated taxon recognition and auxiliary tools for species
description using machine learning.
We presented a synthesis of Brazilian Entomobryomorpha species and new records of the Brazilian oceanic islands located in the Equatorial Atlantic. In this work, we observed the global distributions of the species that inhabit the Brazilian oceanic islands. We presented distribution maps for all species found on the islands and the closest records on the continent. Our study showed that species that occur in the islands also occur in the American continent, mainly in the neotropical region, or are widespread. We established a new neotype of the first species of Collembola described in Brazil together with a detailed morphological study.
A hotspot of subterranean Collembola in ferruginous rock caves and Mesovoid Shallow Substratum is revealed by the analysis of pseudocryptic diversity. The diversity is accessed by detailed description of chaetotaxy and slight variation in morphology of 11 new species of Trogolaphysa Mills, 1938 (Collembola, Paronellidae, Paronellinae) and the 50 previously recorded species of springtails from caves, using optical and electronic microscopy. When combined with recent subterranean surveys, our results show an important reservoir of cave diversity in the Mesovoid Shallow Substratum. Contrastingly the conservation policy for subterranean fauna in metallogenic areas in Brazil prioritizes the caves instead the cave species, which may be extremely detrimental to the fauna in the shallow subterranean habitats not accessible to humans.
A super diverse hot spot of subterranean Collembola in ferruginous rock caves and Mesovoid Shallow Substratum is revealed by the analysis of cryptic diversity. The diversity is accessed by detailed description of chaetotaxy and slight variation in morphology of 11 new species of Trogolaphysa Mills, 1938 (Collembola, Paronellidae, Paronellinae) and the 49 previously recorded species of springtails from caves, using optical and electronic microscopy. When combined with recent subterranean surveys, our results show an important reservoir of cave diversity in the Mesovoid Shallow Substratum, contrasting with the conservation policy for subterranean fauna in metallogenic areas in Brazil which prioritizes the caves instead the cave species, which may be extremely detrimental to the fauna in the shallow subterranean habitats not accessible to humans.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
