A new classification of genus Neoperla and systematic studies of other Perlinae (Plecoptera: Perlidae).

A new formal classification for the largest genus of Perlinae, Neoperla, is introduced to replace the artificial split of the genus into two informal groups. Globally, there are close to 300 named species, with the number rising all the time. The monophyletic clymene-group is assigned to Neoperla (Neoperla) with ~ 140 species in North America, Africa and parts of Asia; its seven main subgroups are briefly characterized.

Revision of the African Neoperla Needham, 1905 (Plecoptera: Perlidae: Perlinae) based on morphological and molecular data.

Adults of the African species of the genus Neoperla Needham, 1905 (Plecoptera: Perlidae: Perlinae) are revised, and 82 valid species are recognised. Of the original 29 named species, 14 valid ones are redescribed from types, nine lectotypes are designated, and nine new synonymies are proposed. Sixty-two new species are named, and several additional new species only known from material insufficient for formal description are listed.

Notes on Perlodinella Klaplek, 1912 (Plecoptera: Perlodidae) with a new species and a new synonym.

After reexamining the syntype series of Perlodinella kozlovi Klaplek, 1912, a new species of Perlodinella, P. tibetensis Huo Du sp. nov.

Catalogue of the Diptera (Insecta) of Morocco- an annotated checklist, with distributions and a bibliography.

The faunistic knowledge of the Diptera of Morocco recorded from 1787 to 2021 is summarized and updated in this first catalogue of Moroccan Diptera species. A total of 3057 species, classified into 948 genera and 93 families (21 Nematocera and 72 Brachycera), are listed. Taxa (superfamily, family, genus and species) have been updated according to current interpretations, based on reviews in the literature, the expertise of authors and contributors, and recently conducted fieldwork.

Australian Marsh Beetles (Coleoptera: Scirtidae). 9. The relations of Australasian Ypsiloncyphon species to their Asian congeners, additions, mainly to Petrocyphon and Prionocyphon, and a key to Australian genera of Scirtinae.

The endemic Australasian species of Ypsiloncyphon are the sister group of the combined Asian species groups 1, 2, and 4. The description of the type species, Y. chlorizans (Klausnitzer), is supplemented by details of male and female genitalia.

Notes on Madagascan Stoneflies (Plecoptera: Notonemouridae).

Madagascar is inhabited by the single stonefly genus, Madenemura Paulian (= Tsaranemura Paulian, new synonymy). The original material of R. Paulian and the types of all nominal species proposed by him are lost.

Australian Marsh Beetles (Coleoptera: Scirtidae). 8. The new genera Cygnocyphon, Eximiocyphon, Paracyphon, Leptocyphon, Tectocyphon, and additions to Contacyphon de Gozis, Nanocyphon Zwick and Eurycyphon Watts.

New monotypic genera proposed are: Cygnocyphon ibex n. gen., n.

Australian Marsh Beetles (Coleoptera: Scirtidae). 7. Genus Nothocyphon, new genus.

The new genus Nothocyphon (type species: Helodes (Cyphon ?) lindensis Blackburn, 1892) is proposed for small Contacyphon-like Australian beetles. The included species exhibit a generalized body structure, lacking the derived character expressions of related genera. Male tergite 9 is very weakly developed, membranous and bare.

Australian marsh beetles (Coleoptera: Scirtidae). 6. Genera Calvarium Pic, Papuacyphon Zwick, and Ypsiloncyphon Klausnitzer.

The genus Calvarium Pic, 1918 is for the first time recorded from Australia. Six new Australian species are named and described. Calvarium australiense n.

Australian marsh beetles (Coleoptera: Scirtidae). 2. Pachycyphon, a new genus of presumably terrestrial Australian Scirtidae.

The genus Pachycyphon is erected for marsh beetles (Coleoptera: Scirtidae) from tropical rainforests in Queensland, Australia. The following species are included: P. corpulentus sp.

Australian Marsh Beetles (Coleoptera: Scirtidae) 4. Two new genera, Austrocyphon and Tasmanocyphon.

The related new genera Austrocyphon and Tasmanocyphon are erected for 42 small Australian marsh beetles resembling members of the genus Cyphon Paykull in habitus. They are distinguished from Cyphon. Only males are known of most species but for two of them larvae and pupae are also available.

Effects of intraspecific competition on the life cycle of the stonefly, Nemurella pictetii (Plecoptera: Nemouridae).

Background: Considerable variation of life cycle duration in given insect species has been frequently recorded. Splitting of populations into cohorts with different life cycle lengths may occur, sometimes even between siblings from the same batch. Larval populations of the stonefly Nemurella pictetii in central Europe regularly split into a very fast developing and a normal univoltine cohort, leading to partial multivoltinism.

Plurimodal emergence and plurivoltinism of Central European populations of Nemurella pictetii (Plecoptera: Nemouridae).

Nemurella pictetii Klapálek, 1900 (Plecoptera: Nemouridae) has bi-or trimodal emergence patterns in Central Europe. The emergence threshold temperature is about 8°C. Egg development is direct.
