Caddisflies (Trichoptera) of the protected territories of Belarus

The caddisfly fauna of 13 protected areas in Belarus is studied. A total of 97 species from the following 12 families are recorded: Hydroptilidae (6 species), Ecnomidae (1), Polycentropodidae (11), Pshychomyidae (1), Hydropsychidae (5), Phryganeidae (12), Brachycentridae (1), Limnephilidae (41), Sericostomatidae (1), Molannidae (1), Beraeidae (3), and Leptoceridae (14). Polycentropus kingi McLachlan, 1881; Agrypnia picta Kolenati, 1848; Limnephilus sericeus (Say, 1824); L. dispar McLachlan, 1875; L. elegans Curtis, 1834, and Hagenella clathrata (Kolenati, 1848) are rare in Europe. Some of the revealed species are critically endangered in several countries of western Europe. The studied protected areas play an important role in conservation of species diversity and in the distribution of several rare species.     

A dragonet (Perciformes: Callionymidae) from the Middle Miocene of southern Russia

From the Middle Miocene (Konkian) deposits in the Taman Peninsula, a new genus and species of dragonets Protonymus gontsharovae gen. et sp. nov. are described, differing from all known recent and fossil members of the family in the structure of the preopercular spine, radialia of pectoral fins, and of otolith (sagitta). The history of dispersal of dragonets in the Paleogene-Neogene is discussed.     

Toxorhina (Ceratocheilus) caucasiensis,a new species from the Middle Miocene of Stavropol (northern Caucasus,USSR) (Diptera,Limoniidae)

Phylogeny of caddisflies (Insecta, Trichoptera)

Trichoptera are holometabolous insects with aquatic larvae that, together with the Lepidoptera, comprise the Amphiesmenoptera. Previous phylogenetic hypotheses and progress on our ongoing data collection are summarized. Fragments of the large and small subunit nuclear ribosomal RNAs (D1, D3, V4–5), the nuclear elongation factor 1 alpha gene and a fragment of mitochondrial cytochrome oxidase 1 (COI) were sequenced, and molecular data were combined with previously published morphological data. Equally and differentially weighted parsimony analyses were conducted in order to present a phylogeny of Trichoptera, including 43 of 45 families. Our phylogeny closely resembles that proposed by Herbert Ross with respect to the relationships among suborders, with a monophyletic Annulipalpia at the base of the tree, and a clade consisting of Spicipalpia plus a monophyletic Integripalpia. The monophyly of Spicipalpia is weakly supported in the combined equally weighted analysis, and Spicipalpia is paraphyletic in the differentially weighted analysis. Within Integripalpia, our phylogeny recovered monophyletic Plenitentoria, Brevitentoria and Sericostomatoidea. Leptoceroidea was unresolved in the equally weighted analysis and monophyletic in the differentially weighted analysis. Within Annulipalpia, we recovered a basal but paraphyletic Philopotamoidea and a monophyletic Hydropsychoidea.     

Phylogeny of the Ecnomidae (Insecta: Trichoptera)

Ecnomidae are a family of seven previously accepted extant genera having a typical Gondwanan distribution, except one genus ( Ecnomus ) being widely distributed also in the Oriental and Palearctic regions. We analysed a molecular data set of 3379 characters representing the sum of four different protein-coding genes (COI, CAD, EF-1a and POL-II). Six equally most parsimonious trees were generated from the combined data set, distributed into two distinct islands. In all maximum parsimony (MP) trees the Ecnomidae is monophyletic when the genus Zelandoptila (Psychomyiidae) is included. The sister group to Ecnomidae including Zelandoptila is Pseudoneureclipsis , previously classified in the other families. This sister-group relationship contradicts earlier findings that the Polycentropodidae are the sister group to Ecnomidae. A Bayesian analysis resulted in a monophyletic Ecnomidae when accepting inclusion of Pseudoneureclipsis , which contradicts the results from the MP analysis by leaving Zelandoptila as the sister group to Ecnomidae including Pseudoneureclipsis . In the majority rule tree from this analysis Polycentropodidae form the sister group to Ecnomidae. We were not able to obtain a monophyletic Ecnomus due to the inclusion of Psychomyillodes . We conclude that the genus Zelandoptila or Pseudoneureclipsis probably belongs to the Ecnomidae, and that Psychomyiellodes and Ecnomus are synonyms. Three additional, as yet undescribed monotypic genera from Australia and New Caledonia remain to be erected in Ecnomidae.

New Insects (Insecta: Trichoptera,Reculida, Eoblattida) from the Mesozoic of Asia

New caddisflies, reculid and eoblattid insects from the Mesozoic of Asia are described. Caddisflies of the families Philopotamidae (Mesoviatrix paradoxa gen. et sp. nov. and Kempia piotri gen. et sp. nov.) and Polycentropodidae (Polylongevus eskovi gen. et sp. nov.) from the Upper Jurassic–Lower Cretaceous of the Kempendyai locality in Yakutia are described. A short review and comparison of fossil members in these families are provided. New Gryllones insects, Shurabia tanga sp. nov., Sauk batkenicus gen. et sp. nov. from the Sauk Tan’ga locality (Lower Jurassic of Kyrgyzstan), Say kirgizicus gen. et sp. nov. from the Shurab III locality (Reculida: Geinitziidae; Lower or Middle Jurassic of Kyrgyzstan) Griphopteron iya sp. nov. (Eoblattida: Blattogryllidae) from Iya locality (Middle Jurassic of Russia) are described.     

Larvae of caddisflies (Insecta: Trichoptera) from the Mesozoic of Siberia

Body fossils of caddisfly larvae are described for the first time based on material from the Lower Cretaceous of Siberia (Baissa locality, Neocomian). The material includes a fully grown larva of Baissoplectrum separatum gen. et sp. nov. (Brachycentridae), Creterotesis coprolithica gen. et sp. nov. (Leptoceridae), and Cretolype minuta gen. et sp. nov., a tiny larva probably belonging to an uncertain family of the suborder Annulipalpia (Hydropsychina). C. coprolithica built unusually soft larval cases of pellets; these cases are described as a separate new indusigenus and indusispecies Coprindusia pallida gen. et sp. nov. Bionomics, taxonomy, and evolution of the Mesozoic larvae of Trichoptera are discussed.     

New records of polycentropodid caddisflies from Korea (Insecta: Trichoptera)

Four species of the family Polycentropodidae –Plectrocnemia baculifera, P. kusnezovi, Paranyctiophylax hjangsanchonus and Polyplectropus nocturnus– are recorded from Korea. Polyplectropus nocturnus is newly recorded from the Korean peninsula. The other three species are recorded from the Republic of Korea for the first time.     

Two New Species of Caddisflies of the Genus Lepidostoma Rambur (Trichoptera: Lepidostomatidae) from the Great Basin

Two new species of Caddisflies from the Great Basin region in California and Nevada are described. Lepidostoma castalianum sp. nov., collected at a spring in the White Mts. of Mono Co., California, is closely related to L. verodum Ross. L. ojanum sp. nov., collected at three separate springs in the White Mts. of Inyo Co., California, and one spring in Mineral Co., Nevada, is a member of the unicolor species group, similar to L. frosti (Milne) and L. unicolor (Banks).     

Biological diversity of the Minnesota caddisflies (Insecta, Trichoptera)

The caddisfly fauna of Minnesota contains at least 277 species within 21 families and 75 genera. These species are based on examination of 312,884 specimens from 2,166 collections of 937 Minnesota aquatic habitats from 1890 to 2007. Included in these totals is my own quantitative sampling of 4 representative habitat types: small streams, medium rivers, large rivers, and lakes, from each of the 58 major Minnesota watersheds from June through September during 1999-2001. All species are illustrated herein, and their known Minnesota abundances, distributions, adult flight periodicities, and habitat affinities presented. Four species: Lepidostoma griseum (Lepidostomatidae), Psilotreta indecisa (Odontoceridae), and Phryganea sayi and Ptilostomis angustipennis (Phryganeidae) are added to the known fauna. An additional 31 dubious species records are removed for various reasons. Of the 5 determined caddisfly regions of the state, species richness per watershed was highest in the Lake Superior and Northern Regions, intermediate in the Southeastern, and lowest in the Northwestern and Southern. Of the 48 individual collections that yielded >40 species, all but 1 were from the Northern Region. Many species, especially within the families Limnephilidae and Phryganeidae, have appeared to decrease in distribution and abundance during the past 75 years, particularly those once common within the Northwestern and Southern Regions. Many species now appear regionally extirpated, and a few have disappeared from the entire state. The loss of species in the Northwestern and Southern Regions, and probably elsewhere, is almost certainly related to the conversion of many habitats to large-scale agriculture during the mid-20th century.     

A new family of the order Grylloblattida (Insecta) from the Middle Permian of Russia

A new family, Ivapteridae fam. nov. (Insecta; Grylloblattida), is described from the Middle Permian locality of Soyana (Arkhangelsk Region; Kazanian Stage). It is most similar to Sojanoraphidiidae O. Martynova, 1952, differing from it in the subcostal field being traversed in the basal half of the wing by long, curved, and strongly oblique crossveins that form a double row of cells, the base of CuA being free, and CuA₁ thin compared to CuA₂. The new family is represented by a single species, Ivaptera sharovi, gen. et sp. nov. An overview of the modern system of the order Grylloblattida is included.
