Two new species of Oecetis from Maliau Basin, Malaysian Borneo, are described for the first time, O. mesospina sp. nov. and O. apelqvisti sp. nov. These two new species bring the total number of Oecetis found on the island of Borneo up to 16.
Article
Oxyethira Eaton, 1873 is one of the most diverse genera of Hydroptilidae, comprising over 240 species distributed in all biogeographical regions. Here three new species of Oxyethira (Trichoglene) Neboiss, 1977 are described and illustrated from male specimens collected in New Caledonia: O. (Trichoglene) hamus sp. nov., recognized by the hook-shaped...
Article
The overall declining state of the western taxonomy is clearly documented by the present fate of the extremely high valued and huge unidentified caddisfly material collected in India and deposited in the Canadian National Collection. Due to the general lack of both financial and scientific resources in taxonomy, this huge collection remained almost...

New Caledonia has a rich Trichoptera fauna with over 200 known species, most of them endemic. The to- tal diversity has been estimated as high as 300 to 600 species. The endemic genus Agmina Ward & Schefter (Ecnomidae, Trichoptera) includes 28 described species. Based on male genitalia morphology and previ- ously published molecular data another 47...

The poorly known, so called widely distributed and highly varying species of the European Rhyacophila fasciata species complex are revised by fine phenomics of the paramere organisation. In this species complex paramere is the most diverse organ. It is the speciation trait integrating the initial split of speciation by its stimulatory and titillati...

The discovery of the new Agaphylax genus with unique paramere organisation has initiated our lineage sorting of tribes by parameres in the Limnephilinae subfamily applying the principles and procedures of fine phenomics in order to establish transformation series of the polarized plesiomorphy-apomorphy character states for each limnephiline genera....

A total of nine families of Trichoptera were identified from material collected in Malaise and light traps in the western part of Nyungwe National Park, southwestern Rwanda, late October 2018. Included in the material was an undescribed species of Pisuliidae which is described herein as Silvatares laetae Ngirinshuti & Johanson sp. nov. The new spec...
Article
The first Trichoptera recorded from New Caledonia were four species described by Kimmins in 1953, each in a new endemic genus. The diversity was increased to eight species with the publication by Sykora in 1967 of three new species in two new genera and a fourth species in a previously established genus. Today, 239 valid species are known from the...
Article
A considerable number of insect species, including Trichoptera, are described from a single specimen, also known as a 'unique' or a 'singleton'. We ask the question of whether this reflects failure to consider variation and related species, lack of collecting effort, or true rarity. In an attempt to answer this question we examine the available lit...

Abstract. We have recognised significant incongruences among the most commonly used taxonomic characters in the European species of Wormaldia genus of the Philopotamidae caddisfly family. During taxonomical analysis and ranking procedures we have recorded incongruent, discorcordant characters also in the taxa in Rhyacophilidae, Hydropsychidae and L...

Empidoidea represent a large and diverse superfamily of true flies, and to date no stable hypothesis on the phylogeny exists. Previous classifications have been based on morphological data and the relationships among several groups are still unknown. Using the mitochondrial genes cytochrome oxidase c subunit I (COI) and cytochrome β (Cytβ) and the...

The caddisfly materials collected by Hungarian zoologists during 25 collecting trips between the years of 1970 and 2016 in the Korean Peninsula was identified and compared when required with Eastern Palaearctic relatives. The appen-dicular genital terminology was adopted and applied to several representatives of Polyphorae taxa. We identified 95 ca...

We inferred the phylogenetic relationships among 58 genera of Sericostomatoidea, representing all previously accepted families as well as genera that were not placed in established families. The analyses were based on five fragments of the protein coding genes carbamoylphosphate synthetase (CPSase of CAD), isocitrate dehydrogenase (IDH), Elongation...
Article
Today's distributions of faunal groups reflect historic events—geological and evolutionary, as well as dispersals, extinctions and chance events. The extent to which each of these contributed to the hydroptilid faunas of mainland Australia, Tasmania, New Guinea, New Zealand, New Caledonia, Fiji and Vanuatu is explored by comparison of the faunal co...

Based on intensive collecting from various sites in Sweden, the genus Dasyhelea Kieffer, 1911 was reviewed and the number of species now known from the country increased from five to twenty. Among the new species recorded there are two species described as new to science, D. dominiakae sp. nov. and D. gothlandica sp. nov., both in the subgenus Dicr...

The phylogeny of Chimarra has previously been examined using morphological characters for a smaller subset of taxa and geographical representativeness. Here molecular data from three genes (COI, CAD and POL-II) are used to reconstruct the phylogeny of the genus. The results show Chimarra to be monophyletic, and that some of the sister groups are pa...

We review the New Caledonian representatives of the Australasian endemic hydroptiline genus Acritoptila, based on examination of a considerable collection of material in the Swedish Museum of Natural History and of types of previously established species. A key for identification of males is given and includes 3 species newly described here: A. par...
Article
The insect order Trichoptera (caddisflies) forms the second most species‐rich monophyletic group of animals in freshwater. So far, several attempts have been made to elucidate its evolutionary history with both morphological and molecular data. However, none have attempted to analyse the time frame for its diversification. The order is divided into...
