Chironomidae (Diptera) of the Šventoji and Žeimena sub-basins in Lithuania.

Background: Chironomidae, commonly known as non-biting midges, are key indicators of the health and biodiversity of freshwater ecosystems. They are also one of the most abundant and diverse groups of aquatic invertebrates. Although Chironomidae are ecologically important, abundant and diverse, there has been limited focused research on this group in Lithuania.

Once upon a fly: The biogeographical odyssey of Labrundinia (Chironomidae, Tanypodinae), an aquatic non-biting midge towards diversification.

Labrundinia is a highly recognizable lineage in the Pentaneurini tribe (Diptera, Chironomidae). The distinct predatory free-swimming larvae of this genus are typically present in unpolluted aquatic environments, such as small streams, ponds, lakes, and bays. They can be found on the bottom mud, clinging to rocks and wood, and dwelling among aquatic vegetation.

Connecting the dots: DNA barcoding and lectotype designation shedding light on Labrundinia longipalpis (Goetghebuer, 1921), an intriguing non-biting midge (Chironomidae, Tanypodinae).

Accurate taxonomic classification is deemed paramount for gaining an understanding of the diversity and distribution of insect species. In this study, an essential stride was made towards advancing the taxonomy of the non-biting midge Labrundinia longipalpis (Chironomidae, Tanypodinae), which serves as the type species of the genus. The distribution of L.

DNA barcodes provide insights into the diversity and biogeography of the non-biting midge (Diptera, Chironomidae) in South America.

South America, particularly within its tropical belt, is renowned for its unparalleled high levels of species richness, surpassing other major biomes. Certain neotropical areas harbor fragmented knowledge of insect diversity and face imminent threats from biodiversity loss and climate change. Hence, there is an urgent need for rapid estimation methods to complement slower traditional taxonomic approaches.

Fittkau & Murray (Chironomidae, Tanypodinae): redescription and phylogenetic position.

The monotypic genus Fittkau & Murray was originally described based on larvae, pupal exuviae and pharate males. The latter prevented the observation of key features, such as wing dimensions, abdominal coloration pattern, and hypopygial apodemes (sternapodeme and phallapodeme), and the description of the adult male was considered incomplete by the authors. Herein, the adult female of is described for the first time, and the adult male, pupa and larva are redescribed and figured based on specimens recently collected in Germany and Norway.

Procladius travassosi (Oliveira, Messias Silva-Vasconcelos, 1992) regarded as a new junior synonym of Procladius stroudi Roback 1982 (Diptera: Chironomidae: Tanypodinae).

Although recent years have seen increased activity regarding chironomid systematics in the Neotropical region (e.g. Oliveira et al.

One new species of the genus Oleia Andersen et Mendes, 2007 (Diptera: Chironomidae: Orthocladiinae), O. fieldsi sp. n.

Chironomus rishii sp. n., an enigmatic non-biting midge (Diptera: Chironomidae: Chironominae) from Neotropical region.

A new species of Chironomus Meigen, C. rishii (Diptera: Chironomidae: Chironominae) from Brazil, is described and figured as adults male and female, pupa and larva. Adults of C.

Sub-fossil Chironomidae (Diptera) from lake sediments in Central America: a preliminary inventory.

The chironomid diversity of Central America is virtually underestimated and there is almost no knowledge on the chironomid remains accumulated in surface sediments of lakes. Thus, in the present study we provide information on the larval sub-fossil chironomid fauna from surface sediments in Central American lakes for the first time. Samples from 27 lakes analysed from Guatemala, El Salvador and Honduras yielded a total of 1,109 remains of four subfamilies.

Tanypus urszulae, a new Tanypodinae (Diptera: Chironomidae) from the Neotropical Region.

A new species of Tanypus Meigen, T. urszulae sp. nov.

Diplosmittia caribensis, a new Orthocladiinae (Diptera: Chironomidae) from the Dominican Republic.

The genus Diplosmittia was erected by Sæther (1981) based on Diplosmittia harrisoni from St. Lucia and St. Vincent in the British West Indies.

Amazonimyia gigantea gen. n., sp. n., a new Tanypodinae (Diptera: Chironomidae) from the Neotropical Region.

A new genus, Amazonimyia, is established for a species of the tribe Pentaneurini (Diptera, Chironomidae, Tanypodinae) from the Amazon Rainforest in northern Brazil. Generic diagnoses for adult male and pupa are provided together with descriptions of a new species, Amazonimyia gigantea.

A taxonomic revision of genus Labrundinia Fittkau, 1962 (Diptera: Chironomidae: Tanypodinae).

The species of the genus Labrundinia (Diptera: Chironomidae: Tanypodinae: Pentaneurini) are revised, described and figured. Keys to known adult males, pupae and larvae are provided. Fourteen previously known species are redescribed, and 25 species from Neotropical region are diagnosed and described as new to science.
