Stark contrasts in clade species diversity are reported across the tree of life and especially conspicuous when observed closely related lineages. The explanation for such disparity has often been attributed to evolution key innovations that facilitate colonization new ecological niches. factors underlying diversification bees remain poorly explored. Bees thought have originated from apoid wasps during Mid-Cretaceous, a period coincides with appearance angiosperm eudicot pollen grains fossil...
A new species of Fidelia Friese, 1899 is described from southern Africa: (Fideliopsis) whiteheadi Litman & Kuhlmann sp. nov. Diagnostic characters are provided to distinguish this others in the genus, particularly closely related F. hessei; an updated description for hessei also given. The host plant preferences and seasonal activity discussed. Finally, a revised, illustrated key genus presented.
At a time when nature conservation has become essential to ensure the long-term sustainability of our environment, it is widely acknowledged that actions must be implemented within solid taxonomic framework. In preparation for upcoming update IUCN Red List, we here European checklist wild bees (sensu geographical framework). The original checklist, published in 2014, was revised first 2017. present revision, add one genus, four subgenera and 67 species recently described, 40 newly recorded...
Abstract Pollinators play a crucial role in ecosystems globally, ensuring the seed production of most flowering plants. They are threatened by global changes and knowledge their distribution at national continental levels is needed to implement efficient conservation actions, but this still fragmented and/or difficult access. As step forward, we provide an updated list around 3000 European bee hoverfly species, reflecting current distributional status level (in form present, absent,...
We present a supermatrix approach to the phylogeny of Insecta that stemmed from talk given at 2nd Dresden Meeting on Insect Phylogeny (2005). The data included fragment 28S (D1–D8) and complete sequences for 18S, histone (H3), EF-1α, COI, COII, 12S 16S plus intervening tRNA, 170 morphological characters. Ribosomal RNA were manually aligned secondary structure. Two separate Bayesian likelihood analyses performed, as well weighted parsimony analysis, combined data. Partitioned datasets also...
Abstract Dictyoptera, comprising Blattaria, Isoptera, and Mantodea, are diverse in appearance life history, strongly supported as monophyletic. We downloaded COII, 16S, 18S, 28S sequences of 39 dictyopteran species from GenBank. Ribosomal RNA were aligned manually with reference to secondary structure. included morphological data (maximum 175 characters) for 12 these taxa an additional 15 (for which we had only data). two datasets, a 59‐taxon dataset five outgroup taxa, Phasmatodea (2 taxa),...
Abstract The Palaearctic complex of anthidiine bees closely related to Pseudoanthidium scapulare has long been a source unresolved taxonomic and systematic issues. Until now, the number species in their geographical distributions were largely unclear, thus complicating compilation accurate checklists hindering conservation efforts. In order address these issues, we use morphology mitochondrial cytochrome c oxidase subunit I (COI) sequences, combined with thorough examination relevant...
The evolution of parasitic behavior may catalyze the exploitation new ecological niches yet also binds fate a parasite to that its host. It is thus not clear whether evolutionary transitions from free-living organism lead increased or decreased rates diversification. We explore brood parasitism in long-tongued bees and find diversification eight 10 clades. propose pathway for strategy which closed host nest cell parasitized offspring killed by adult represents an obligate first step...
Butterfly monitoring and Red List programs in Switzerland rely on a combination of observations collection records to document changes species distributions through time. While most butterflies can be identified using morphology, some taxa remain challenging, making it difficult accurately map their develop appropriate conservation measures. In this paper, we explore the use DNA barcode (a fragment mitochondrial gene COI) as tool for identification Swiss forester moths (Rhopalocera...
Abstract Fideliine bees are an archaic group with a disjunct distribution mostly restricted to deserts of S outh A merica and frica. This was previously thought be more diverse in frica than merica, where only one genus ( N eofidelia ) comprising five species is known. Here we describe belonging second merican genus: X enofidelia colorada P acker gen. et sp.n. , from northern C hile. The illustrated its phylogenetic position within M egachilidae assessed using morphological, molecular...
Recent field surveys in the eastern Canary Islands (Spain), followed by contributions of new occurrence records through citizen science platform iNaturalist.com and social media photo repository Flickr.com have revealed presence an overlooked small carder bee species (genus Pseudoanthidium Friese (Megachilidae: Anthidiini)) on islands Lanzarote Fuerteventura. Here, we combined morphology, DNA barcodes (mitochondrial cytochrome c oxidase subunit I, COI ) ecological data (distribution,...
