New species of Tanytarsus van der Wulp (Diptera: Chironomidae: Tanytarsini) from Brazil

Abstract

Five new species of Tanytarsus van der Wulp (Diptera: Chironomidae: Tanytarsini) from Brazil are described and illustrated. T. longitubuli sp. n. and T. pseudocurvicristatus sp. n., are described as larva, pupa and male; T. hirsutus sp. n., as male and pupa, and T. corumba sp. n. and T. jatai sp. n. as males. Except for one species from Pantanal (western central Brazil), most species were collected in southeast Brazil, from lowland streams and lakes. New occurrences of known species of Tanytarsus in Brazil, Mato Grosso do Sul and Mato Grosso states, are also given.

Molecular phylogeny and temporal diversification of Tanytarsus van der Wulp (Diptera: Chironomidae) support generic synonymies, a new classification and centre of origin

“…giovannii Sanseverino & Trivinho‐Strixino and T . pseudocurvicristatus Trivinho‐Strixino, Wiedenbrug & da Silva (Sanseverino & Trivinho‐Strixino, ; Trivinho‐Strixino et al ., ), and also in the Australian species Tanytarsus liepae Glover (Glover, ). The broad lateral comb on the pupal abdominal segment VIII is also present in Tanytarsus edwardi Glover and T .…”

“…Specimens were identified morphologically using relevant taxonomic revisions and species descriptions (e.g. Lindeberg, , ; Reiss & Fittkau, ; Glover, ; Sasa, ; Sasa & Kawai, ; Sublette & Sasa, ; Cranston, ; Ekrem, , ; Ekrem et al ., ; Sanseverino, ; Cranston, ; Vinogradova et al ., ; Trivinho‐Strixino, , Trivinho‐Strixino et al ., ; Dantas & Giłka, ).…”

“…(). The Neotropical fauna has also been described quite extensively (Sublette & Sasa, ; Ekrem & Reiss, ; Sanseverino & Wiedenbrug, ; Sanseverino et al ., ; Sanseverino, ; Sanseverino & Fittkau, ; Cranston, ; Trivinho‐Strixino & Strixino, ; Vinogradova et al ., ; Sanseverino & Trivinho‐Strixino, ; Giłka & Zakrzewska, ; Trivinho‐Strixino et al ., ; Dantas & Giłka, ; Trivinho‐Strixino & Shimabukuro, ), and Sanseverino et al . () suggested the synonymy of the New World genus Nimbocera Reiss with Tanytarsus .…”

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

“…The latter was represented by five species, Tanytarsus types A-E. This genus is one of the most species rich genera of Chironomidae in the Neotropical region, and the immature stages occur in several different aquatic ecosystems (Trivinho-Strixino et al 2015). The identification of adults of Tanytarsus is problematical due to the large interspecific variation in the genitalic morphology (Ekrem & Reiss 1999).…”

“…The identification of adults of Tanytarsus is problematical due to the large interspecific variation in the genitalic morphology (Ekrem & Reiss 1999). In spite of this drawback, recent years have seen increased interest concerning the taxonomy of the group in the Neotropical region Trivinho-Strixino et al 2015).…”
