On the enigmatic troglobitic scorpion Troglorhopalurus translucidus: distribution, description of adult females, life history and comments on Rhopalurus lacrau (Scorpiones: Buthidae)

Zoologia (Curitiba)
We describe for the first time the adult female of the troglobitic scorpion Troglorhopalurus translucidus Lourenço Baptista & Giupponi, 2004, and broaden its known distribution to other sandstone caves at Chapada Diamantina's region.

Two New Troglobitic Species of Giupponia Pérez-González & Kury, 2002 (Opiliones: Gonyleptoidea) from Caves of Bahia, Northeastern Brazil

Animals
Cave-dwelling harvestmen (Opiliones: Laniatores: Gonyleptoidea) include trogloxenes, troglophiles and troglobites, frequently represented as monotypic genera, likely reflecting taxonomic practice rather than true diversity.

Into the Darkness: Unveiling Unexpected Records of the Nonnative Millipede Prosopodesmus jacobsoni Silvestri, 1910 (Polydesmida: Haplodesmidae) in Brazilian Caves

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT This study expands the known distribution of the nonnative millipede Prosopodesmus jacobsoni in Brazil and reports its presence in cave environments for the first time in the country. Based on recently collected material and historical records, the species is shown to maintain stable populations in subterranean systems in the states of ...

Secrets of the Spring‐Keepers: Phylogeographic Analyses of a Freshwater Amphipod Uncover Dispersal Pathways in Eastern North America

Journal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim While the Nearctic freshwater amphipod Gammarus minus is known for its adaptation to groundwater environments, relatively little is known about other aspects of the evolutionary history of the species throughout its range, which spans much of the eastern United States.

Expanding the knowledge of Hyalella Smith, 1874 (Amphipoda: Hyalellidae) for southeast Brazil: two new troglophilic species from caves of the Atlantic Rainforest [PDF]

Nauplius
The present work describes two new species of Hyalella Smith, 1874 from two different state parks in Southeastern Brazil. Both species were collected in well-preserved and conserved areas of the Atlantic Rainforest, the first from the Parque Estadual ...

Cave depth and subterranean connectivity are drivers of intraspecific trait variability in two subterranean congeneric beetles

Ecological Entomology, Volume 51, Issue 1, Page 153-164, February 2026.
The abundance of cave beetles increases with depth, with Duvalius hartigi exhibiting maximum densities at greater depths in volcanic systems. Troglomorphic traits become more pronounced with increasing depth exclusively in the alpine species Duvalius carantii.

Hidden Diversity of Cave Millipedes From Mainland Southeast Asia Revealed by Species Delimitation and Phylogenetic Analysis, With a Description of a New Genus (Spirostreptida: Cambalopsidae)

Journal of Zoological Systematics and Evolutionary Research, Volume 2026, Issue 1, 2026.
Southeast Asia’s karst landscapes host a remarkable yet understudied diversity of cave‐dwelling fauna, where morphological conservatism often masks true species boundaries. Using an integrative taxonomic framework, we investigated the systematics of the millipede family Cambalopsidae Cook, 1895 inhabiting caves across Thailand, Laos, Myanmar, and ...

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, Volume 63, Issue 6, Page 1501-1518, November 2025.
Investigating the systematics and biogeography of Neotropical catfishes of the genus Rhamdia refined phylogenetic hypotheses, including deep paraphyly of Rhamdia laticauda, supported northward dispersal catalyzed by emergence of the Panamanian Isthmus and imply that cave colonization is widespread, convergent, and recent, with established cave‐dwelling

Diversity of Potamolithus (Littorinimorpha, Truncatelloidea) in a high-diversity spot for troglobites in southeastern Brazil: role of habitat fragmentation in the origin of subterranean fauna, and conservation status

Subterranean Biology, 2018
The Alto Ribeira karst area, southeastern Brazil, is a high-diversity area for troglobites. Three species of freshwater gastropods Potamolithus occur in the area: P.

Light in the Darkness: Responses to Light and Diel Activity Rhythm in an Eyeless Cave Flatworm (Dendrocoelum italicum)

Ecology and Evolution, Volume 15, Issue 6, June 2025.
Loss of non‐functional and costly structures associated with surface conditions is favoured during adaptation to cave environment. We show that eyeless cave flatworms express photophobic responses to light stimuli and retain diel rhythmicity in activity patterns.
