Special Issue Information

Dear Colleagues,

Cave environments represent some of the most enigmatic ecosystems on the planet. Isolated from sunlight and often with limited resources, caves are home to highly specialized organisms adapted to permanent darkness, constant humidity, and nutrient scarcity. Studying cave fauna is relevant to the conservation of subterranean habitats.

We are pleased to invite you to submit scientific articles to this Special Issue addressing various aspects of subterranean life, with an emphasis on creatures that inhabit caves.

This Special Issue aims to bring together work that will expand our knowledge of biological diversity, ecological and evolutionary processes, and the challenges around preserving organisms that inhabit caves. Interdisciplinary research and innovative approaches are especially encouraged.   

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Zoology;
  • Cave ecology;
  • Physiology of subterranean fauna;
  • Adaptive evolution;
  • Biogeography;
  • Conservation of hypogeal environments.

We look forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly 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 2400 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.
  • Reprint: MDPI Books provides the opportunity to republish successful Special Issues in book format, both online and in print.

Abstract
Cave-dwelling harvestmen (Opiliones: Laniatores: Gonyleptoidea) include trogloxenes, troglophiles and troglobites, frequently represented as monotypic genera, likely reflecting taxonomic practice rather than true diversity. Giupponia Pérez-González & Kury, 2002 is one such case: it was erected for the blind troglobite G. chagasi from limestone [...] Read more.
Cave-dwelling harvestmen (Opiliones: Laniatores: Gonyleptoidea) include trogloxenes, troglophiles and troglobites, frequently represented as monotypic genera, likely reflecting taxonomic practice rather than true diversity. Giupponia Pérez-González & Kury, 2002 is one such case: it was erected for the blind troglobite G. chagasi from limestone caves in Serra do Ramalho, southwestern Bahia, Brazil, and has remained monotypic for more than two decades. Here, we describe two additional troglobitic species from caves in the same karst area, thereby expanding the genus and providing an updated diagnosis and an identification key for males. The new species share core troglomorphic traits with G. chagasi (complete eye loss and depigmentation) and a distinctive suite of external and genital characters that support their placement in Giupponia, including a theta-type dorsal scutum with wide ridged grooves, a prominent preocular mound with paired spiniform armature, an enlarged ocularial apophysis, and a characteristic penial configuration with a pyriform ventral plate, a parabolic distal cleft and a robust stylus bearing a dorsal projection, with the glans lacking dorsal/ventral processes. We further discuss the morphological evidence bearing on the suprageneric placement of Giupponia within Gonyleptoidea Sundevall, 1833, highlighting affinities with lineages traditionally treated in Pachylinae and possible relationships with Ampycidae Kury, 2003 or Tricommatinae Roewer, 1912. These findings underscore the hidden diversity of the Serra do Ramalho subterranean fauna and the need for integrative phylogenetic analyses to resolve the evolutionary origin of extreme troglomorphisms in Brazilian gonyleptids.
