Prof. Dr. Claudio Gilberto Froehlich, a naturalistic legacy overcoming the biodiversity knowledge shortfalls

ABSTRACT The limited knowledge of biodiversity constrains conservation strategies in a wide range of questions. Overcoming and recognizing these knowledge deficits require integrated efforts by current researchers and constitute crucial challenges for the next generations. Prof. Dr. Claudio Froehlich was a pioneer in implementing a research program integrating ecology and taxonomy, especially in aquatic insects, in Brazil. This special issue was conceptualized to honor his prolific scientific career and constitutes a tribute to the pioneering in Brazilian aquatic entomology. A brief biography of Prof. Dr. Claudio Froehlich was presented as well as 13 papers facing the biodiversity knowledge shortfalls from five insect orders (Diptera, Ephemeroptera, Neuroptera, Plecoptera, Trichoptera), with behavior reports (Eltonian shortfall), 23 new species described (Linnean shortfall), and distribution records for several taxa (Wallacean shortfall).

New species of Claudiotendipes Andersen, Mendes & Pinho and Tapajos Trivinho-Strixino, Silva & Oliveira from Brazil (Diptera, Chironomidae, Chironominae)

ABSTRACT Two recently revealed genera, Claudiotendipes, consisting of three distinct species, and the monotypic Tapajos, have new species described. We describe and figure Claudiotendipes gilbertoi sp. n., based on male adult specimens collected in the southern Atlantic Forest of Rio Grande do Sul State. Additionally, we describe and figure Tapajos froehlichi sp. n., from male adults collected in the Amazon Forest from Amazonas and Rondônia States. In order to place the newly described T. froehlichi sp. n., minor emendations have been made to the diagnosis and description of Tapajos.

Not just a taxonomist, but a naturalist! The foundations of "Froehlich's Autonomous Stonefly Republic"

ABSTRACT Prof. Dr. Claudio Gilberto Froehlich's career is presented here using numbers and actions guided by a genuine way to study biodiversity, especially aquatic ecosystems. An extensive number of publications is accompanied by an investment in human resources training and establishing a vast network of collaborators and friendships. Dr. Peter Zwick mentioned the Southeast Region of Brazil as "Froehlich's Autonomous Stonefly Republic", to express the magnitude of Prof. Froehlich's scientific production on Neotropical Plecoptera. In this special volume in honor of Prof. Froehlich, the numbers of his career support Zwick's affirmation. Thirty-nine students graduated in MSc and/or PhD courses, two books, and 20 book chapters were published, as well as 95 articles on geoplanids, onychophorans, cnidarians, mayflies, coleopterans, caddisflies, and especially stoneflies. Froehlich's legacy includes different ways to observe nature, from taxonomy to ecology, from flatworms to stoneflies.

A new species of Saetherocryptus Andersen et Mendes, 2007 from Brazil (Diptera: Chironomidae, Orthocladiinae) / Uma nova especie de Saetherocryptus Andersen et Mendes, 2007 para o Brasil (Diptera: Chironomidae, Orthocladiinae)

Saetherocryptus Andersen et Mendes, 2007 was described as monotypic, based on S. clavatus Andersen et Mendes, 2007 from Mata Atlântica in south and southeast Brazil. A second species, S. temimino sp. n., is described and figured below based on an adult male from São Paulo State.

Saetherocryptus Andersen et Mendes, 2007, até então monotípico, foi descrito com base em S. clavatus Andersen et Mendes, 2007 da Mata Atlântica do sul e sudeste do Brasil. Uma segunda espécie, S. temimino sp. n., é descrita e ilustrada abaixo com base em um macho adulto do Estado de São Paulo.
