Introduction
Acquiring more knowledge about the patterns and processes shaping life on earth is of great importance during a time when biodiversity in many regions is seriously threatened. My research attempts to contribute to the knowledge and understanding of the great diversity of Lepidoptera and Trichoptera, and combines studies on systematics, biogeography and diversification with genomics and museomics.

Article
Butterflies (Papilionoidea), with over 18,000 described species [1], have captivated naturalists and scientists for centuries. They play a central role in the study of speciation, community ecology, biogeography, climate change, and plant-insect interactions and include many model organisms and pest species [2, 3]. However, a robust higher-level ph...

Butterflies and moths (Lepidoptera) are one of the major super-radiations of insects, comprising nearly 160,000 described extant species. As herbivores, pollinators, and prey, Lepidoptera play a fundamental role in almost every terrestrial ecosystem. Lepidoptera are also indicators of environmental change and serve as models for research on mimicry...

Museum collections around the world contain billions of specimens, including rare and extinct species. If their genetic information could be retrieved at a large scale, this would dramatically increase our knowledge of genetic and taxonomic diversity information, and support evolutionary, ecological and systematic studies. We here present a target...

Full-text available
Parapatrically distributed taxa pose a challenge for species delimitation due to the presence of gene flow and inherent arbitrariness of exactly defining the species boundaries in such systems. We tackled the problem of species delimitation in a parapatric species pair of Melitaea butterflies using two popular genomic methods—double digest restrict...
Preprint
Butterflies are a diverse and charismatic insect group that are thought to have diversified via coevolution with plants and in response to dispersals following key geological events. These hypotheses have been poorly tested at the macroevolutionary scale because a comprehensive phylogenetic framework and datasets on global distributions and larval...

It is shown that Catochrysops trifracta Butler, 1884, currently a synonym of the widespread old world Euchrysops cnejus (Fabricius, 1798) is a junior subjective synonym of the neotropical species Hemiargus hanno (Stoll [1790]). To fix the taxonomic identity of the name Catochrysops trifracta Butler, 1884, I designate a lectotype.

New methods in taxonomy and systematics can influence the overall practice of formally naming and describing biodiversity. DNA barcoding has been controversial since its emergence, but now, large scale species descriptions exclusively based on barcodes have created what can be called a 'new quality of performance'. Its limitations are discussed fro...
Article
A new species of Taydebis Freitas, 2003 from south Brazil is described using comparative morphology and species distributions. Also, based on morphology, we transfer Neonympha melobosis Capronnier, 1874 (formerly placed in Paryphthimoides Forster, 1964) to Taydebis, and recognize Euptychia peculiaris Butler, 1874 as its junior synonym (syn. nov.)....

Species are the fundamental units of life and their recognition is essential for science and society. DNA barcoding, the use of a single and often mitochondrial gene, has been increasingly employed as a universal approach for the identification of animal species. However, this approach faces several challenges. Here, we demonstrate with empirical d...

Billions of specimens can be found in natural history museum collections around the world, holding potential molecular secrets to be unveiled. Among them are intriguing specimens of rare families of moths that, while represented in morphology-based works, are only beginning to be included in genomic studies: Pseudobistonidae, Sematuridae, and Epico...
Article
DNA ‘barcoding’ has contributed greatly to resolving species limits in rapidly diverging tropical insect groups. Here, we explored species diversity in the widespread, cryptic Neotropical butterfly genus Hermeuptychia by generating 601 new sequences of the cytochrome c oxidase I (COI) barcode, tripling available information. Our dataset focused in...

Diversification rates and evolutionary trajectories are known to be influenced by phenotypic traits and the geographic history of the landscapes that organisms inhabit. One of the most conspicuous traits in butterflies is their wing color pattern, which has been shown to be important in speciation. The evolution of many taxa in the Neotropics has a...
Article
Vareuptychia Forster, 1964 stat. rest. is revalidated and comprises two species, V. similis (Butler, 1867) comb. rest. and V. themis (Butler, 1867) comb. nov. Vanima Zacca, Casagrande Mielke gen. nov. is described to contain Euptychia labe Butler, 1870 (the type species), E. palladia Butler, 1867 and E. lesbia Staudinger, [1886]. The taxonomy of th...
Article
The butterfly tribe Candalidini is geographically restricted to Australia and mainland New Guinea and its adjacent islands. With 60 species and subspecies, it represents a large radiation of Papilionoidea in the Australian region. Although the species‐level taxonomy is relatively well understood, the number of genera is uncertain, varying from two...

Full-text available
Three new fossil species from Burmese amber are described, one clearly in family Calamoceratidae, the other two in the highly variable family Odontoceridae. The family Odontoceridae contains 18 disparate genera, but there are no good diagnostic characters, which makes it difficult to place fossil taxa in this family. We here offer a revised diagnos...
Article
Peronia J. Fleming, 1822 is an eupulmonate slug genus with a wide distribution in the Indo-Pacific Ocean. Currently, nine species are considered as valid. However, molecular data indicate cryptic speciation and more species involved. Here, we present results on a new species found in the Persian Gulf, a subtropical region with harsh conditions such...
Article
A systematic revision of Paryphthimoides , a satyrine genus widely distributed in Central and South America, is presented based on an integrative approach. Molecular phylogeny inferred using multiple methods with nuclear (GAPDH, RpS5) and mitochondrial (COI) genes indicates that Paryphthimoides , as currently circumscribed, is polyphyletic. A new t...

Background: Butterflies (Papilionoidea) are perhaps the most charismatic insect lineage, yet phylogenetic relationships among them remain incompletely studied and controversial. This is especially true for skippers (Hesperiidae), one of the most species-rich and poorly studied butterfly families. Methods: To infer a robust phylogenomic hypothesi...
Article
Relationships within satyrine butterflies have been notoriously difficult to resolve using both morphology and Sanger sequencing methods, and this is particularly true for the mainly Neotropical subtribe Euptychiina, which contains about 400 described species. Known larvae of Euptychiina feed on grasses and sedges, with the exception of the genus E...

A new Lepidochrysops species is described and figured from Western Zambia, Lepidochrysops ella sp. n. and a diagnosis for its separation from other similar Lepidochrysops is provided.
Article
The role of specialization in diversification can be explored along two geological axes in the butterfly family Lycaenidae. In addition to variation in host-plant specialization normally exhibited by butterflies, the caterpillars of most Lycaenidae have symbioses with ants ranging from no interactions through to obligate and specific associations,...
