“…It is thus possible that sound production has been overlooked in some genera, families or even orders. Moreover the diversity of aquatic insects might still need taxonomic description in some areas of the world [10]. This would thus suggest that our estimate of the potential number of soniferous aquatic insect species is lower than the real number and there is potential for detecting additional species.…”

“…Aquatic insects are insects with at least one life stage bound to water. It is estimated that there are approximately 76 000 species of aquatic insects worldwide [10]. Aquatic insects are probably the most important contributors to freshwater soundscapes globally owing to their high abundance, diversity and propensity to produce sounds underwater [11,12].…”

Aquatic insects are a major indicator used to assess ecological condition in freshwater environments. However, current methods to collect and identify aquatic insects require advanced taxonomic expertise and rely on invasive techniques that lack spatio-temporal replication. Passive acoustic monitoring (PAM) is emerging as a non-invasive complementary sampling method allowing broad spatio-temporal and taxonomic coverage. The application of PAM in freshwater ecosystems has already proved useful, revealing unexpected acoustic diversity produced by fishes, amphibians, submerged aquatic plants, and aquatic insects. However, the identity of species producing sounds remains largely unknown. Among them, aquatic insects appear to be the major contributor to freshwater soundscapes. Here, we estimate the potential number of soniferous aquatic insects worldwide using data from the Global Biodiversity Information Facility. We found that four aquatic insect orders produce sounds totalling over 7000 species. This number is probably underestimated owing to poor knowledge of aquatic insects bioacoustics. We then assess the value of sound producing aquatic insects to evaluate ecological condition and find that they might be useful despite having similar responses in pristine and degraded environments in some cases. Both expert and automated identifications will be necessary to build international reference libraries and to conduct acoustic bioassessment in freshwaters. This article is part of the theme issue ‘Towards a toolkit for global insect biodiversity monitoring’.

“…The actual arthropod diversity/ abundance of tepui ecosystems is largely unknown. Only a few invertebrate groups have been the subject of more detailed treatments (often taxonomic and/or zoogeographic), such as butterflies (e.g., Viloria & Costa, 2019), scorpions (e.g., Ochoa & Rojas-Runjaic, 2019), land snails (e.g., Breure, 2019), ants (e.g., Jaffe et al, 1993), and some aquatic insects (e.g., Derka et al, 2019), but these studies provide no or only fragmentary data on the species quantitative abundance and ecology. Furthermore, most of these studies focus on invertebrates that are too large to be preyed upon by Oreophrynella.…”

The Guiana Shield highlands in northern South America are one of the most stunning, remote, and least explored biogeographical regions of the world. Often referred to as the "Lost World" based on Arthur Conan Doyle's eponymous fiction novel (Doyle, 1912), this region is called Pantepui (Mayr & Phelps, 1967; Figure 1). Pantepui harbors dozens of isolated Precambrian sandstone tabletop mountains (called "tepuis"; Figure 2) reaching up to ca. 3,000 m elevation and is renowned for its floral and faunal endemism (Berry et al., 1995;Kok, 2013a;McDiarmid & Donnelly, 2005). The high tepui summits are challenging, highly competitive ecosystems that are both physiographically and ecologically isolated from the more fertile surrounding environments. Their vegetation grows on highly acidic, oligotrophic soils and is drastically different from the vegetation of the intervening uplands. Tepui summits are isolated from each other and from the surrounding upland savannah and tropical rainforest by up to 1,000 m high vertical cliffs and face contrasted, particularly hostile climatic conditions (strong cold winds, extreme temperature/hygrometry variation), and high solar and ultraviolet (UV) radiation (McDiarmid & Donnelly, 2005). The summit of Roraimatepui (ca. 2,800 m elevation) is characterized by a submicrothermic
