“…The aquatic highland species adapted to the harsh conditions of highland environments (Vellard 1951; Sáez et al . 2022), such as the endangered Titicaca water frog ( Telmatobius culeus ; IUCN SSC Amphibian Specialist Group 2020), have morphological, physiological and ecological peculiarities related to feeding and communicating underwater (Barrionuevo 2016; Brunetti et al . 2017; Muñoz‐Saravia 2018), as well as to enduring low oxygen levels and pronounced temperature fluctuations (Hutchison et al .…”

We describe the new frog Telmatobius achachila sp. nov. from the late Middle to earliest Late Miocene of Achiri, based on a partial skeleton found at 3960 m above sealevel in the Bolivian Altiplano. This skeleton, attributed to a male adult, constitutes the first documented fossil record of the speciose living genus Telmatobius, endemic to the Andean Cordillera and the Altiplano. Phylogenetic analysis confirms the new species as being part of the crown group, and diverging both later than the T. verrucosus group and earlier than the T. bolivianus, T. marmoratus and T. macrostomus groups. Coupled with its accurate stratigraphic provenance and age, this phylogenetic position provides a relevant calibration point for timing the evolutionary history of these highland, mostly aquatic frogs. The skeleton of T. achachila indicates that several of the osteological peculiarities of extant Telmatobius were already acquired at c. 12 Ma, including some that might be linked to their aquatic lifestyle. Together with mixed montane–rainforest pollen vegetation uncovered in the same level, this fossil specimen further provides key data enabling a more accurate reconstruction of ancestral habitats and elevation ranges of Telmatobius, agreeing with the previously postulated conditions in which these water frogs might have first evolved. Ultimately, this discovery adds to the sparse evidence of a humid tropical Bolivian Altiplano just prior to: (1) the Late Miocene uplift pulse of the Central Altiplano; and (2) the drastic climate deterioration that occurred from Late Miocene time onward, leading to the harsh highland‐steppe environments reigning there today.

“…The knowledge on natural history of the Aquatic Andean Frogs of the genus Telmatobius was increased in the last decade (Catenazzi et al 2013, Lobos et al 2016, Brunetti et al 2017, Acosta et al 2020, Gastón 2022, Sáez et al 2022, particularly about feeding habits, diet and trophic ecology (Barrionuevo 2016, Watson et al 2017, Lobos et al 2018, Akmentins and Gastón 2020, Muñoz-Saravia et al 2020, Abdenur-A et al 2022. One shared characteristic of most Telmatobius species is that these frogs inhabit high-altitude Andean lotic and lentic aquatic systems, characterized by their simplified food webs (Lujan et al 2013).…”

Evaporitic ecosystems of the Atacama Desert contain a rich endemic fauna, including mollusk species. A recent study performed in the freshwater snail Heleobia atacamensis, endemic to the Atacama Saltpan, revealed a strong interdependence of genetic patterns with climatic fluctuations and landscape physiography. The species is currently listed as Critically Endangered at regional scale and as Data Deficient on the International Union for Conservation of Nature (IUCN) Red List. Here, we studied genetic diversity and demographic history of several populations of the species occurring on a connectivity gradient, including snails from new peripherical localities (Peine and Tilomonte), which were compared with topotype specimens. In addition, we reassessed the conservation status using the IUCN Red List categories and criteria considering species-specific idiosyncrasy. Phylogenetic and phylogeographical analyses indicated that snails from Peine and Tilomonte belong to H. atacamensis. We discovered significant differentiation in shell morphology, which was generally greater in geographically isolated populations. We also inferred six genetic clusters and a demographic expansion congruent with the wet periods that occurred at the end of the Pleistocene. Considering the highest risk category obtained, H. atacamensis was reassessed as Endangered at regional scale. Future conservation plans should consider the genetic assemblages as conservation units.
