Caddisflies (Insecta: Trichoptera) from Maranhão State, Northeast Region, Brazil: A new species, checklist, and new geographical records

Abstract

In order to improve knowledge of Trichoptera diversity in Northeast Region, Brazil, we present here the first checklist of caddisflies from Maranhão State with a description of a new species and geographical records for the Northeast Region and for all of Brazil. Collections were made in 16 sites distributed in three municipalities of Maranhão State. A total of 54 caddisflies species, 26 genera and 10 families were recorded, including one new species of Leptoceridae, Triplectides maranhensis sp. nov., which is described and illustrated. All species listed here are recorded for the first time for the state, 23 of which are new records for the Northeast Region, as well as five new species for Brazil. These results increase the number of species reported from the Northeast Region from 167 to 221.

Caddisflies (Trichoptera) checklist and a new species of Helicopsyche von Siebold, 1856, from the Brejo de Altitude de Triunfo, a relict rainforest within the Caatinga domain, Northeast Brazil

“… Smicridea ( Smicridea ) palifera presents a wide distribution in Brazil, except in the south of the country ( Santos et al 2022 ). In the Northeast region it has been registered in four states (altitude range of 53 m and 814 m) ( Souza et al 2013a ; Desidério et al 2017 ; Desidério et al 2020 ). It was recorded in the Caatinga domain, Pernambuco state ( Souza et al 2013a ) and later the Cerrado and Atlantic Forest domains ( Desidério et al 2017 ; Desidério et al 2020 ).…”

“…Amazonas] Remarks. In the Northeast of Brazil, the occurrence of this species was recorded for the Caatinga and Cerrado domains (altitude range 60-448 m) (Souza et al 2013a;Desidério et al 2017;Moreno et al 2020). This study expands its occurrence for rainforest islands of higher elevations (altitude range 580-940 m) on Brejo de Altitude.…”

Triplectides Kolenati (Trichoptera: Leptoceridae) from Brazil: A new species, new records and an identification key

“…Its highest diversity occurs in the Australian Region, with 15 species recorded from New Caledonia and 25 from Australia (Malm & Johanson 2008). In the Neotropical Region there are 17 species described, distributed from southern Mexico to southern Chile (Holzenthal & Calor 2017;Desidério et al 2017). So far, eight species have been recorded from Brazil: T. cipo Henriques-Oliveira & Dumas, 2015, T. egleri Sattler, 1963, T. gracilis (Burmeister, 1839, T. itatiaia Dumas & Nessimian, 2010, T. maranhensis Desidério, Barcelos-Silva & Pes, 2017, T. misionensis Holzenthal, 1988, T. neotropicus Holzenthal, 1988and T. ultimus Holzenthal, 1988(Santos et al 2019.…”

An overview of the ant fauna (Hymenoptera: Formicidae) of the state of Maranhão, Brazil

“…The biodiversity of Maranhão is extremely diverse (Chaves et al, 2016;Desidério et al, 2017). Compared to other Brazilian states, however, the ant diversity is poorly known.…”
