Smicridea (Smicridea) nigripennis species group (Trichoptera: Hydropsychidae) from Brazil: new species, new distributional records and an identification key

Abstract

Three new species in the Smicridea (Smicridea) nigripennis species group are described and illustrated based on specimens collected in Serra da Mocidade National Park and Serra do Tepequém in the northern mountain range of Brazilian Amazonia, Roraima State, and in Rio Formosinho located in Cerrado biome of midwestern Brazil, Mato Grosso do Sul State. Smicridea (Smicridea) mocidade Desidério & Rázuri‐Gonzales, sp. nov., Smicridea (Smicridea) santosi Desidério & Rázuri‐Gonzales, sp. nov. and Smicridea (Smicridea) tepequensis Desidério & Rázuri‐Gonzales, sp. nov. can be recognised mainly by the morphology of the phallic apparatus. New distributional records are provided for Smicridea (Smicridea) caatinga Alves et al., 2018, Smicridea (Smicridea) franciscana Rocha et al., 2016, Smicridea (Smicridea) mirnae Almeida & Flint, 2002 and Smicridea (Smicridea) palifera Flint, 1981. Smicridea (Smicridea) cornuta Flint, 1974 is recorded for the first time from Brazil. Additionally, a key to identify males of the 10 species in the Smicridea (Smicridea) nigripennis species group known from Brazil is provided.

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

“…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). This is the first record in Brejo de Altitude.…”

“…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).…”

The Smicridea (Smicridea) fasciatella species group (Trichoptera: Hydropsychidae) in Brazil: six new species and new distributional records

“…Although Smicridea is highly diverse and widely distributed in Brazil, its geographic distribution is poorly known, and its diversity may be underestimated because some Brazilian states, regions, and biomes have not been sampled yet. Some recent contributions have been made to reduce the biodiversity shortfalls regarding the Brazilian Smicridea fauna (Rocha et al 2016;Alves et al 2018;Vilarino et al 2019;Desiderio et al 2020Desiderio et al , 2021. In this paper, we describe six new species of S. (Smicridea), significantly increasing the number of species of this subgenus in Brazil from 21 to 27.…”

“…Species descriptions were made using the DELTA (Description Language for Taxonomy) software (Dallwitz et al 1999) to promote consistency and standardization in descriptive taxonomy. The style of descriptions follows Desiderio et al (2020).…”
