“…To proceed the segmental delimitation and definition, we addressed the results from developmental biology (Hopkin 1997, Jura et al, 1987, Tomizuka & Machida 2015, and the chaetal fields were defined using SEM (Tescan Vegas III) to map the clusters of chaetae associated to cuticular landmarks. Cephalic chaetotaxy, great abdomen chaetotaxy, and small abdomen (abdominal segment VI) chaetotaxy followed the system proposed by Betsch & Waller (1994) and Betsch (1997). For the appendages, we followed Nayrolles (1988Nayrolles ( , 1990aNayrolles ( , 1990bNayrolles ( , 1991 for antennae, legs and furcula; and tenaculum after Richards (1968).…”

“…The Order Symphypleona Borner, 1901 shows some ambiguity in current morphological methods, particularly when describing the head and body chaetotaxy (Betsch 1997, Betsch & Waller 1994, Bretfeld 1990, Christiansen & Bellinger 1998. The Order is composed by springtails with globular body shape, as result of modification and fusion of thoracic and abdominal segments I-IV, this condition hinders the direct assignment of segments identity.…”

“…The most abundant morphological source of information for species definition in Collembola is the number, distribution, and shape of cuticular chaetae, this is called chaetotaxy. The current morphological approaches for inference of homology, chaetotaxic systems for chaetal identification, are often room for great subjectivity depending on what is seen and what is visible under an optic microscope, and often different chaetotaxy systems are hardly comparable (Betsch 1997, Betsch & Waller 1994, Bretfeld 1990, Potapov et al, 2020. The challenges and perspectives for Collembola taxonomy is discussed in detail, and the need for an integrative taxonomy and international efforts to direct financial support and expertise recognition to face the global biodiversity crisis, was also the focus of debate (Potapov et al, 2020, Zeppelini et al, 2021.…”

“…Furthermore, it must be presented in an interchangeable language, to allow the information to flow across different disciplines. Among all methods applied to the external morphology study of Collembola, chaetotaxy is certainly the most complex and extensively detailed (Betsch & Waller 1994, Cassagnau 1974, Deharveng 1983, Fjellberg 1999, Jordana & Baquero 2005, Nayrolles 1988, 1990a, 1990b, Potapov 2001, Szeptycki 1979, 1972, Yosii 1960. There are many chaetae and groups of chaetae that vary in position and shape in such a way that they allow a great deal of homology inferences.…”

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.

A Highly Troglomorphic New Genus of Sminthuridae (Collembola, Symphypleona) from the Brazilian Semiarid Region

Here, we describe the highly troglomorphic Troglobentosminthurus gen. nov. from Água Clara cave system, Caatinga domain, Bahia, Brazil. Troglobentosminthurus luridus gen. nov. sp. nov. has remarkably long antennae, legs and furca, and lacks body pigments, except for small orange eye patches which also show a reduction in the number of eyes (5 + 5) and lens sizes. The overall morphology of the genus, with long and highly sub-segmented antennae, resembles other Sminthurinae of the Temeritas-group, especially Temeritas Richards and Galeriella Ćurčić and Lučić. However, it is unique, especially in the combination of the number of antennae IV subsegments and eyes, frontal head chaetotaxy and empodial complex morphology. Two type specimens have remnants of a mite and another specimen from the new species in their gut contents, supporting the species may be occasional predators and even cannibals. We also provide identification keys and comparative tables to the subfamilies of Sminthuridae and the Temeritas-group of genera.

A proposal for taxonomic species description notation is presented to replace the traditional descriptive texts for a coded matrix, avoiding redundant adjectives and subjective descriptions. This is an attempt to enhance the species description rate and to make the descriptions output available to other scientific disciplines, machine learning, interactive and computer‐assisted identification keys, metadata analysis and its applications. The method consists of 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 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 descriptions are dynamic, expandable and can be easily used in other fields of science, allowing non‐experts to access the data for phylogenetic, biogeographic, ecological studies and metadata analysis. Even though an experienced taxonomist will always be necessary to make a detailed taxonomic description, it is a step forward to a general template to semi‐automated taxon recognition and to future development of auxiliary tools for species description using machine learning and templates to speed up the time‐consuming phase of schematic figures preparation, after the expert interpretations are done.
