Special Issue Information

Dear Colleagues, 

The Order Araneae currently comprises over 50,000 described species, which certainly represents only a fraction of the group’s true diversity. Spiders show wide morphological, behavioral and ecological diversity, and they have been routinely studied as a biogeographic model. Despite the importance of the group and all the interest it attracts from experts in differing disciplines, it still lacks work focused on taxonomy and diversity, since many genera are currently in need of taxonomic revision, and many taxa hold umpteen species to be described. Additionally, most of the already described species are poorly known geographically, and most sites could have their spider fauna extensively surveyed. We are living in a particularly interesting moment to embrace the challenge of deepening our basic knowledge on spiders, as advances in molecular data acquisition and analysis are expanding the knowledge of the phylogeny and classification of the group, as well as creating new opportunities to understand the tempo and mode of its evolution. Thus, we invite the arachnological community to submit research manuscripts on aspects of taxonomy, systematics and diversity in Araneae.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Taxonomy is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

A New Genus of Prodidominae Cave Spider from a Paleoburrow and Ferruginous Caves in Brazil (Araneae: Prodidomidae)

Abstract
A new monotypic genus of Prodidominae, Paleotoca gen. n., is proposed to include one cave species collected in a paleoburrow and ferruginous caves from Quadrilátero Ferrífero, Minas Gerais, Brazil: Paleotoca diminassp. n. (♂♀). The new genus is closely related to [...] Read more.
A new monotypic genus of Prodidominae, Paleotoca gen. n., is proposed to include one cave species collected in a paleoburrow and ferruginous caves from Quadrilátero Ferrífero, Minas Gerais, Brazil: Paleotoca diminassp. n. (♂♀). The new genus is closely related to other Neotropical Prodidominae by sharing the classic claw tuft clasper. Paleotoca gen. n. is diagnosed by the absence of a dorsal abdominal scutum, a ventral parallel rows of strong spines on the tibia and metatarsus I–II, a lack of a conductor, a discrete median apophysis on the bulb and a bifid retrolateral tibial apophysis in the male palp, a posterior extension that is beak-shaped, and folds of a copulatory duct ventrally visible in the female epigyne. Like other Prodidominae species from caves, P. diminassp. n. is a troglobitic spider with morphological characteristics that indicate specialization to live in subterranean environments, including reduction in cuticular pigments, eye loss, heavy spination and trichobothria.

The Nearctic family Hahniidae is seldom found in South America; only 20 species occur on the continent. Herein, we present the first record of the family in mainland Ecuador, with the description of thirteen new species in five different genera. In Amaloxenops: A. minimalista n. sp. (female); in Kasha n. gen.: Kasha patpa n. sp. (male, female); in Neohahnia: Neohahnia catleyi (female) n. sp., N. piemontana n. sp. (male, female), N. pristirana n. sp. (male, female), N. freibergi n. sp. (male, female), N. paramo n. sp. (male, female), and N. chalupas n. sp. (male); in Paramito n. gen.: Paramito papallacta n. sp. and P. oyacachi n. sp.; and in Pristirana n. gen.: Pristirana barthlotti n. sp. (male, female), P. niederi n. sp.
