We describe a new species of collected in the High Atlas Mountains of Morocco. appears to be morphologically more similar to the European highly endangered (Müller, 1785) than to the other Maghrebian species, Bojkova & Soldán, 2015. A gene tree including the few available barcode sequences of Palearctic specimens is provided.

Baetidae (Baetidae, Ephemeroptera) in the Maghreb: state of the art, key, and perspectives.

Among mayflies, Baetidae are often considered as easy to recognise at the family level, but difficult to identify at lower level. In several faunistic or ecological studies, the identification remains at the family level; Baetidae are generally considered as widespread and ubiquitous, therefore as poorly informative for ecological studies or bioassessments. Here, a straightforward identification key is offered to larvae of the ten genera of Baetidae reported from Maghreb based on easily observable and understandable characters.

 sp. nov., a new species of mayfly (Ephemeroptera, Ephemerellidae) from Thailand.

This new species is classified in the complex of the genus based on morphological and COI phylogeny evidence. The new species is closely related to (Uéno, 1928) and Martynov, Selvakumar, Palatov & Vasanth, 2021 based on body colour pattern.

Critical morphological diagnostic characters distinguishing the new species are presented, together with molecular affinities as well as notes on the biology and distribution of the species.

What Ecological Factors Favor Parthenogenesis over Sexual Reproduction? A Study on the Facultatively Parthenogenetic Mayfly in Natural Populations.

AbstractDifferent reproductive modes are characterized by costs and benefits that depend on ecological contexts. For example, sex can provide benefits under complex biotic interactions, while its costs increase under mate limitation. Furthermore, ecological contexts often vary along abiotic gradients.

A new species of Traver, 1938 from Hispaniola (Ephemeroptera, Leptophlebiidae, Hagenulinae, Hagenulini).

Here, I report a new species of the genus Traver, 1938 from the Dominican Republic. The genus was believed to be endemic to Puerto Rico until now. is described at the nymphal stage.

Contribution to knowledge of the Trichoptera of northwestern Algeria: New species records for the Algerian fauna and taxonomic remarks for the Maghreb fauna.

The caddisfly fauna of Algeria is far from complete. In this study, we present data from Trichoptera sampling in northwestern Algeria (Tafna and Ghazouana River basins) during 20142019, enhancing knowledge of this group in the country. We were able to identify 30 species and 17 genera in the study area.

Behningiidae and Potamanthidae (Insecta, Ephemeroptera) in Thailand.

The aim of this study is to review the family Behningiidae and Potamanthidae in Thailand. Two genera and three species of Behningiidae are recognised: Peters & Gillies, 1991, McCafferty & Jacobus, 2006, and Zhou & Bisset, 2019, which is newly reported from Thailand. The egg structure of is described for the first time using scanning electron microscopy.

First record of Eaton, 1881 (Ephemeroptera, Heptageniidae) from Thailand with description of a new species.

A new species of Heptageniidae, , is described based on larvae, subimagos, eggs, and COI data. The mayfly genus Eaton, 1881 is reported for the first time from Thailand. The larva of the new species can be distinguished from other known species by i) lamellae of gill I ca 1/4 of fibrilliform portion and ii) mandibles and basal segment of maxillary palp without dense setae on margin.

Larval Taxonomy and Distribution of Genus Hydropsyche (Trichoptera:Â Hydropsychidae) in Northwestern Algeria.

The main purpose of our paper is to document genus Hydropsyche (Trichoptera: Hydropsychidae) in northwestern Algeria and to provide the larval descriptions of the species set. Larvae, pupae, and imagines were collected from 14 sampling sites over a five-year period (2014-2019). Eight Hydropsyche species have been identified, with Hydropsyche siltalai being a new record for Algeria and North Africa, and Hydropsyche pellucidula a new record for Algeria.

A reassessment of the genus Crass, 1947 (Ephemeroptera, Oligoneuriidae, Oligoneuriellini).

The distinction between the two closely related genera Ulmer, 1924 and Crass, 1947 has been much debated. First described from South Africa, seemed to be a clearly defined genus. However, as the known distribution of the genus widened and knowledge on it expanded, species delimitation based on morphology became less clear due to overlap in several apparently defining morphological characters, especially in the nymphs.

Stylogomphus thongphaphumensis (Odonata: Anisoptera: Gomphidae), a new gomphid dragonfly and the first record of S. malayanus Sasamoto, 2001 from Thailand.

Stylogomphus thongphaphumensis sp. nov. is described from a type series of specimens reared from larvae (holotype ♂, Huai Khayeng, Thong Pha Phum district, Kanchanaburi Province; 14°36'20″N 98°34'38″E, 206 m a.

Extremely Widespread Parthenogenesis and a Trade-Off Between Alternative Forms of Reproduction in Mayflies (Ephemeroptera).

Studying alternative forms of reproduction in natural populations is of fundamental importance for understanding the costs and benefits of sex. Mayflies are one of the few animal groups where sexual reproduction co-occurs with different types of parthenogenesis, providing ideal conditions for identifying benefits of sex in natural populations. Here, we establish a catalog of all known mayfly species capable of reproducing by parthenogenesis, as well as species unable to do so.

Reports of Baetidae (Ephemeroptera) species from Tafna Basin, Algeria and biogeographic affinities revealed by DNA barcoding.

Background: The Mediterranean basin is known to be the cradle of many endemic species. Within mayflies (Insecta, Ephemeroptera), North African species belonging to the family Baetidae remain poorly known and, traditionally, affinities to European fauna were proposed. Recent studies, based on molecular reconstructions, showed closer relationships to Mediterranean islands fauna.
