“…S924 ). If we compare the number of species and the number of patterns, we identify an expected positive slope, but with a low fit of the model (R 2 = 0.23), although the interpretation is limited by the present state of the biodiversity inventory 84 , 85 , 127 , 128 . If we consider the real number of species identified in New Guinea (~ 1300 spp., unpublished data), the R 2 value doubles.…”

Biologists have reported on the chemical defences and the phenetic similarity of net-winged beetles (Coleoptera: Lycidae) and their co-mimics. Nevertheless, our knowledge has remained fragmental, and the evolution of mimetic patterns has not been studied in the phylogenetic context. We illustrate the general appearance of ~ 600 lycid species and ~ 200 co-mimics and their distribution. Further, we assemble the phylogeny using the transcriptomic backbone and ~ 570 species. Using phylogenetic information, we closely scrutinise the relationships among aposematically coloured species, the worldwide diversity, and the distribution of aposematic patterns. The emitted visual signals differ in conspicuousness. The uniform coloured dorsum is ancestral and was followed by the evolution of bicoloured forms. The mottled patterns, i.e. fasciate, striate, punctate, and reticulate, originated later in the course of evolution. The highest number of sympatrically occurring patterns was recovered in New Guinea and the Andean mountain ecosystems (the areas of the highest abundance), and in continental South East Asia (an area of moderate abundance but high in phylogenetic diversity). Consequently, a large number of co-existing aposematic patterns in a single region and/or locality is the rule, in contrast with the theoretical prediction, and predators do not face a simple model-like choice but cope with complex mimetic communities. Lycids display an ancestral aposematic signal even though they sympatrically occur with differently coloured unprofitable relatives. We show that the highly conspicuous patterns evolve within communities predominantly formed by less conspicuous Müllerian mimics and, and often only a single species displays a novel pattern. Our work is a forerunner to the detailed research into the aposematic signalling of net-winged beetles.

“…Calochrominae is cosmopolitan, with its origin in Southeast Asia (Motyka et al ., 2017), and Conderini is mainly Oriental, with a few species in the Palearctic region. The Lycini (2 spp., Figs 2D, 3) has been identified as a Neotropic group dispersing to Asia via the Beringia route and, later, to Africa, eventually western Asia (Kusy et al ., 2021). Several highly diversified tribes are absent in the WPR, and they belong to groups of presumed Neotropical/Mesoamerican (Lycinae: Platerodini) or Australian (Metriorrhynchini: Cautirina) origins (Bocakova 2001; Sklenarova et al ., 2013; Masek et al ., 2018).…”

Only twenty-two net-winged beetle species (Elateroidea: Lycidae) are known from the Western Palearctic region (WPR), i.e., less than 0.5% of the global lycid diversity and much fewer than from the similar latitudes of East Asia or Northern America. We use the comprehensive distribution data and the molecular phylogeny of ~400 world lycids, including fourteen European species, to provide a new perspective for understanding the structure and evolution of this group in the WPR. All Mediterranean species represent deeply rooted lineages with relatives in Eastern Asia. These species occur in relictual ranges close to the family's Pleistocene refugial edge. The phylogeny points to the loss of biological connection with East Asia since the Mid Miocene. A third of WPR species is widespread in Central and Northern Europe, reaching Eastern Asia, some of them possibly younger elements of the European fauna. Unlike relatively high diversity in the Eocene amber, the extant net-winged beetles represent a small fraction of elateroid diversity in the WPR and are generally rare. Therefore, we assume that most WPR species are relics trapped in Mediterranean refugia since the onset of the Plio-Pleistocene cooling and are critically endangered by the ongoing loss of suitable habitats.

“…To build the species list of Colombian Lycidae, information was compiled from the taxonomic catalogs of Kleine (1933) and Blackwelder (1945), and complemented with subsequent taxonomic works involving Colombian Lycidae (Nascimento and Bocakova 2009, Kazantsev 2011, Bocakova et al 2012, Ferreira 2016, Ferreira and Ivie 2016, considering strictly the taxa formally described from the country, published by Nascimento (2021), using nomenclature and classification according to Bouchard et al (2011), Motyka et al (2017), Masek et al (2018), Kusy et al (2020), andMotyka (2023).…”

A checklist of the genera and species of Lycidae occurring in Colombia is presented. After studying nine Colombian entomological collections, in addition to the information from the literature, 152 species and 27 genera are recorded from the country, of which four genera are newly recorded from Colombia: Brasilycus, Ceratopriomorphus, Lycoplateros, and Teroplas. The genus Calopteron presented the widest distribution (29 departments), the only genus occurring in Arauca, Córdoba, La Guajira, and Vaupés. Most genera in Colombia occur from lowland habitats (~500 m) up to 2000 m, whereas Idiopteron Bourgeois, 1905, showed the widest altitudinal range, from about 30 m to 3900 m. An illustrated key to identify the Colombian genera is provided.
