A newly discovered representative of Leptophlebiidae is described and illustrated from Thailand as Sangpradubina thailandica, gen. nov. sp. nov., based on larvae reared adults. This new species presents an interesting transitional position, being close to Choroterpes s.l. in the winged stages, but closer Thraulus nymphal stage. Nymphs are differentiated those all genera lineage by combination gill I consisting only a single slender lamella, gills II-VII fimbriate distal half, each mandible...

A new species belonging to the speciose genus Electrogena Zurwerra & Tomka, 1985 is described based on all stages from material collected in Switzerland, northern Italy and Slovenia. brulini Wagner sp. nov. closely related E. gridellii (Grandi, 1953). genetic analysis mitochondrial gene CO1, including 9 specimens 5 populations, reveals a K2P distance of 22% between both species. Our investigations demonstrate that description nymph sensu Belfiore (1996) refers fact Therefore, redescribed...

We present here a new species of Habrophlebia, H. hassainae sp. nov., described at nymphal, imaginal and egg stages obtained by rearing from the Tafna watershed, North western Algeria. The was previously identified as cf. fusca Gagneur & Thomas (1988). is in fact more related to lauta McLachlan, 1884, but can be separated different characters on male imago nymphs. This third Habrophlebia reported Africa.

Larvae of the Notacanthella Jacobus & McCafferty, 2008 species N. commodema (Allen, 1971) and quadrata (Kluge Zhou, 2004) from Thailand are compared redescribed. Both have serrations on maxillary canines, as does perculta Vietnam, this contributes to synonymizing subgenus Samiocca under s.s. (= n. syn.). The can be differentiated by numbers thoracic abdominal tubercles. In addition, chorionic structure is investigated for first time scanning electron microscopic technique.

A comprehensive revision of the genus Thalerosphyrus in Thailand is assessed. Four species are recognised: T. flowersi, sinuosus, vietnamensis and one new species, thailandensis sp. nov., which described here. morphological comparison provided. Maximum Likelihood (ML) consensus tree based on 658 bp mitochondrial cytochrome oxidase I (COI) gene five was performed. Uncorrected p-distances strongly support identity these originally morphology, show differences 8.4–29.8% between 1.4–6.3% within...

Abstract. This study represents the first formal morphological and combined (morphological molecular) phylogenetic analyses of order Ephemeroptera. Taxonomic sampling comprised 112 species in 107 genera, including 42 recognized families (all major lineages Ephemeroptera). Morphological data consisted 101 characters. Molecular were acquired from DNA sequences 12S, 16S, 18S, 28S H3 genes. The Asian genus Siphluriscus (Siphluriscidae) was supported as sister to all other mayflies. Carapacea,...

Aquatic larvae of many Rhithrogena mayflies (Ephemeroptera) inhabit sensitive Alpine environments. A number species are on the IUCN Red List and recognized have restricted distributions conservation interest. Despite their ecological importance, ambiguous morphological differences among closely related suggest that current taxonomy may not accurately reflect evolutionary diversity group. Here we examined status nearly 50% European using a widespread sampling scheme included 22 type...

Stylogomphus thongphaphumensis sp. nov. is described from a type series of specimens reared larvae (holotype ♂, Huai Khayeng, Thong Pha Phum district, Kanchanaburi Province; 14°36′20″N 98°34′38″E, 206 m a.s.l., larva collected on 14.XII.2014; adult emerged 30.IV.2015). All were the same locality in western Thailand. Description (based preserved exuviae) provided as well. The this species can be distinguished other Fraser, 1922, by morphology male anal appendages, pterothoracic pattern,...

Cloeon perkinsi was described from South Africa in 1932 by Barnard. Despite being relatively common Africa, it mentioned the literature quite rarely, and its known distribution to date includes most of sub-Saharan Africa. Material collected recently Ethiopia, Israel, Saudi Arabia, Yemen extends East Arabian Peninsula Levant. We examined this material, provide a re-description adults (females males) nymphs species. It represents much-needed urge mainly due inconsistencies reports regarding...

Material collected just behind the Cenderawasih University campus in Jayapura, Papua Province, Indonesia, revealed a new species of Labiobaetis claudiae group, which is here described and illustrated based on larvae, subimago, male female imagos. The total number island New Guinea increased to 33, for Indonesia 26, worldwide augmented 147. A key larvae L. group provided. interspecific K2P distances between are 20% 23%.

We investigated the relative importance of dispersal and vicariance in forming Madagascar insect fauna, sequencing approximately 2300 bp from three rRNA gene regions to investigate phylogeny Afrotropical small minnow mayflies (Ephemeroptera: Baetidae). Six lineages contained trans-oceanic sister taxa, variation genetic divergence between taxa revealed relationships that range very recent ancient vicariance. Dispersal was most frequent species spend larval stage standing water, adding...

The main purpose of our paper is to document genus Hydropsyche (Trichoptera: Hydropsychidae) in northwestern Algeria and provide the larval descriptions species set. Larvae, pupae, imagines were collected from 14 sampling sites over a five-year period (2014–2019). Eight have been identified, with siltalai being new record for North Africa, pellucidula Algeria. A comparison checklist those Moroccan Rif Europe provided, as well geographical distribution each species. This Algerian revision...

The effects of deforestation on species richness and abundance tropical freshwater organisms are increasingly well documented, but corresponding functional properties ecosystems, such as productivity growth, largely unknown. Here we investigated the biomass production growth eight mayflies (Ephemeroptera) in streams eastern Madagascar. We compared three study sites primary forest with degraded open canopy area (savoka). All were asynchronous aseasonal. Seven multivoltine (3-4 generations per...

The island nation of Madagascar, an international conservation priority, is now also recognized as a global hotspot for freshwater biodiversity. Three emerging characteristics Madagascar's threatened biota deserve increased attention from the scientific and communities. First, species richness not low, was once assumed both fishes invertebrates. Second, many are restricted to specific region or even single river basins. Often these limited streams rivers draining primary forest habitat....

Summary The Canary Islands and Madeira are reportedly home to seven recognised species of baetid mayflies (Ephemeroptera, Baetidae), two which also occur on the European mainland. Their status remains unsure, loss habitat suggests they conservation concern. We applied morphological characters a general mixed Yule‐coalescent (gmyc) model analysis cytochrome c oxidase subunit 1 ( cox1 ) gene delineate putative within morphologically cryptic groups Baetis Rhodobaetis Cloeon dipterum s.l. used...

The caddisfly fauna of Algeria is far from complete. In this study, we present data Trichoptera sampling in northwestern (Tafna and Ghazouana River basins) during 20142019, enhancing knowledge group the country. We were able to identify 30 species 17 genera study area. Among listed taxa, five (Hydroptila fortunata, Ecnomus deceptor, Tinodes waeneri, Limnephilus lunatus, Setodes argentipunctellus,) are new records for Algeria. An updated checklist Algerian includes 63 species. also provide an...

Mayflies (Ephemeroptera) are known to generally present a high degree of insular endemism: half the 28 species from Corsica and Sardinia considered as endemic. We sequenced DNA barcode (a fragment mitochondrial CO1 gene) 349 specimens 50 localities in Corsica, Sardinia, continental Europe North Africa. reconstructed gene trees eight genera or groups representing main mayfly families. Alternative topologies were built test if our reconstructions suggested single multiple Corsican/ Sardinian...
