“…Samples of free-living larvae were also taken from the pond using an aquatic net. The larvae were collected in 90% ethyl alcohol from the second pond and identified to species level based on the keys provided by Hubbard (1984) and Rathinakumar et al (2019) and also confirmed by a taxonomist specialising in Ephemeroptera (Dr. Boonsatien Boonsoong, Bangkok, Thailand). Further, efforts were also made to collect information from Mr Sebastian, Proprietor Shakthi Tarpaulin in Kerala who supply tarpaulin sheet for farmers and also people who previously encountered holes in tarpaulins installed in rain water harvesting units.…”

Mayflies are important as macroinvertebrates of aquatic ecosystems and are reliable bioindicators of water quality. Most mayfly nymphs feed by scraping algae from underwater rocks or by extracting food particles in the littoral and benthic zones of the water bodies. The mayfly Povilla (Languidipes) taprobanes originally described from Sri Lanka was observed in plastic lined ponds in coastal Karnataka. Not only, this is the first report of the species from Karnataka, but the unique case making behaviour of this species is also described for the first time. Additionally, the species was found damaging plastic tarpaulins of 750 gsm thickness used as lining for water storage in the tank by chewing. This chewing behaviour was responsible for damage of plastic sheets leading to water leakage. The possible loss caused and a need of alternate strategies to store water is discussed.

“…It is possible that the males described here as L. janae represent the adult stage of one of them, but this seems unlikely. Nevertheless, we prefer to describe the new species because it constitutes the unique record from Borneo, and its size is relatively smaller than the other species ( Hubbard, 1984 ; Rathinakumar, Kubendran & Balasubramanian, 2019 ; Bolotov et al, 2022 ; Pai et al, 2023 ). While we believe that obtaining a DNA barcode would have been very helpful for the future association of nymphs or female adults, this technique couldn’t be pursued due to the nature of the available material.…”

“…Languidipes corporaali (Lestage) was subsequently recorded from other Indonesian localities (Sumatra and Simeulue), as well as from Malaysia and Thailand ( Baumgardner et al, 2012 ). The genus Languidipes also includes the species L. taprobanes ( Hubbard, 1984 ) ( Hubbard, 1984 ; Rathinakumar, Kubendran & Balasubramanian, 2019 ; Pai et al, 2023 ), from India and Sri Lanka, and the recently described L. lithophagus ( Bolotov et al, 2022 ) from Myanmar.…”

A new species of Languidipes Hubbard (Ephemeroptera, Polymitarcyidae) from Borneo

The genus Languidipes is currently represented by three species distributed in southeastern Asia, India, and Sri Lanka. Languidipes corporaali is the most widely distributed species, and both, male and female imagos, as well as nymphs, are known. In contrast, the other species, L. taprobanes and L. lithophagus, are only known from nymphs. Here, we describe a new species, Languidipes janae sp nov, based on male imagos collected from Borneo, Indonesia. This new species is characterized by the presence of ommation on mesonotum, and penis almost completely divided, with sub-quadrate base and a small outer projection basal to the long and slender distal arms. This constitutes the first record of the genus for Borneo. A cladistic analysis of the subfamily Asthenopodinae supports its taxonomic status.

Bioerosion of siliceous rocks driven by rock-boring freshwater insects

et al. 2022

View full text Add to dashboard Cite

Macrobioerosion of mineral substrates in fresh water is a little-known geological process. Two examples of rock-boring bivalve molluscs were recently described from freshwater environments. To the best of our knowledge, rock-boring freshwater insects were previously unknown. Here, we report on the discovery of insect larvae boring into submerged siltstone (aleurolite) rocks in tropical Asia. These larvae belong to a new mayfly species and perform their borings using enlarged mandibles. Their traces represent a horizontally oriented, tunnel-like macroboring with two apertures. To date, only three rock-boring animals are known to occur in fresh water globally: a mayfly, a piddock, and a shipworm. All the three species originated within primarily wood-boring clades, indicating a simplified evolutionary shift from wood to hardground substrate based on a set of morphological and anatomical preadaptations evolved in wood borers (e.g., massive larval mandibular tusks in mayflies and specific body, shell, and muscle structure in bivalves).
