Comparative anatomy of the larvae of argid sawflies (Hymenoptera: Argidae): a phylogenetic approachOrganisms Diversity and Evolution - Tập 21 - Trang 361-392 - 2021

The larval stage remains unknown for many sawflies, making it difficult to explore the phylogenetic significance of larval morphology. Here, we assemble a data set from the larval anatomy of 22 genera of Argidae and Zenargidae. We scored 85 characters for 48 terminal taxa and use a maximum parsimony approach applying equal (EW) and implied weights (IW) for phylogenetic reconstruction. We describe ...... hiện toàn bộ
Two tribes hidden in one genus: the case of Agaedioxenis Villeneuve (Diptera: Tachinidae: Exoristinae)Organisms Diversity and Evolution - Tập 15 - Trang 489-512 - 2015

The Afrotropical tachinid “genus” Agaedioxenis Villeneuve is taken here as an example of the challenges faced by dipterists in classifying one of the most diverse and species rich families of organisms on Earth. Our study has revealed “two tribes hidden in one genus”, with one lineage representing a genus belonging to the tribe Goniini (Agaedioxenis) and the other representing a genus belonging to...... hiện toàn bộ
Cryptic and pseudo-cryptic diversity in the world’s most common bark beetle—Hypothenemus eruditusOrganisms Diversity and Evolution - Tập 17 - Trang 633-652 - 2017

Hypothenemus eruditus is regarded as the world’s most common bark beetle, collected from numerous host plants on all forested continents. Previous taxonomic treatments remark that the species is morphologically variable and difficult to identify, but to date, no study has analyzed molecular data to investigate possible cryptic or seemingly cryptic (pseudo-cryptic) diversit...... hiện toàn bộ
Ecomorphology of a generalist freshwater gastropod: complex relations of shell morphology, habitat, and fecundityOrganisms Diversity and Evolution - Tập 18 - Trang 425-441 - 2018

Evolutionary and ecological situations in a species’ native and invasive ranges can be drastically different. This is the case for Potamopyrgus antipodarum Gray (1843) a morphologically highly variable freshwater snail native to New Zealand, where sexual and asexual individuals coexist and experience selective pressure by sterilizing endoparasites. By contrast, only a few asexual lineages have bee...... hiện toàn bộ
Cryptic diversity, sympatry, and other integrative taxonomy scenarios in the Mexican Ceratozamia miqueliana complex (Zamiaceae)Organisms Diversity and Evolution - Tập 17 - Trang 727-752 - 2017

According to the integrative taxonomy (IT) framework, delimitation of taxonomic specimens into bona fide species requires the incorporation of multiple sources of biological evidence that jointly perform a role as systematic criteria. Here, we collected a combination of geographic, morphological (qualitative and quantitative), and molecular data sets from a group of specimens in the Ceratozamia mi...... hiện toàn bộ
