Objectives: Mayflies (Insecta: Ephemeroptera) were collected from the Ohio River, Wabash River and White River in Indiana during July and August 2019, with the goals of confirming the continued existence of historic populations of species and discovering previously undocumented populations.
Data Description: Notable new data for Ephoron album (Say) (Polymitarcyidae), Heptagenia elegantula (Eaton) (Heptageniidae), Pentagenia vittigera (Walsh) (Palingeniidae), and Tortopsis primus (McDunnough) (Polymitarcyidae) are reported.

Heavy metal and microplastic pollutions are prevalent in freshwater ecosystems, with many freshwater bodies being contaminated by one or both of these pollutants. Recent studies reported extreme detections of Cd, Pb and Zn, high concentrations of Cr, Pb and Cu and microplastics acting as vectors of pollutants, including heavy metals. Mayflies can serve as bioindicators of heavy metal contamination in freshwater ecosystems because changes in their community structure, physiology, and behaviour can reflect and help predict the concentrations of metals in these environments.

- - The study uses scanning electron microscopy to investigate the egg structures of six species from two subgenera of East Palaearctic insects in the Russian Far East, revealing variations in adhesive layer thickness and micropyle type based on species.
- - Eggs from the subgenus Ephemera possess a notably thick adhesive layer, while those from Sinephemera have thinner, more amorphous layers, with distinct micropyle characteristics observed across species.
- - Chorion structures vary significantly among species, showing different textures like smooth, reticulate, and wrinkled, which proves essential for identifying and classifying the eggs and their corresponding species.
Article Synopsis
- A new species of larvae, Clypeocaenis laosensis sp. nov., was identified in central and southern Laos from various rivers and streams.
- The study also includes the first descriptions of eggs for two other related species, Cl. multisetosa and Cl. oligosetosa, expanding the known diversity of Caenidae in Laos to five species.
- C. laosensis is differentiated from other Clypeocaenis species by specific morphological traits, detailed comparisons are provided, along with a key for identifying nymphs of Oriental Clypeocaenis species.
Isonychia taishunensis Huang, Shen, Zhang & Cheng sp. nov. is described based on larval samples from Taishun County, Zhejiang Province, China.

The male imago of Americabaetis titthion is described for the first time. It can be distinguished from other male imagos of the genus by the following combination of characteristics: turbinate portion of the eyes with upper surface ellipsoidal and separated by approximately the width of a lateral ocellus; costal area of fore wings tinged with reddish-brown; presence of pairs of soft, setose protuberances on the meso- and metasternum; subgenital plate slightly concave; forceps with segment I/II slightly tapering medioapically. Supplementary descriptions for the nymph and female imago are provided, as well as the first description of the eggs of a species of the genus.
