“…S1), we calculated the net rate of diversification using the method-of-moments (MoM) estimator (Magallón & Sanderson 2001), implemented in the function bd.ms in the R package geiger (Harmon et al 2008). This function allows estimating the net diversification rate conditioning it to the crown-age of the clade (retrieved from the BEAST MCC tree generated above), the number of extant species (obtained from Pinto & Bologna 1999; Bologna & Pinto 2002; Campos-Soldini et al 2018), and the relative extinction rate; the latter was fixed to the value estimated by TreePar for the backbone phylogeny.…”

Changes in life history traits, including reproductive strategies or host shifts, are often considered triggers of speciation, affecting diversification rates. Subsequently, these shifts can have dramatic effects on the evolutionary history of a lineage. In this study, we examine the consequences of changes in life history traits, in particular host-type and phoresy, within the hypermetamorphic clade of blister beetles (Meloidae). This clade exhibits a complex life cycle involving multiple metamorphoses and parasitoidism. Most tribes within the clade are bee-parasitoids, phoretic or non-phoretic, while two tribes feed on grasshopper eggs. Species richness differs greatly between bee and grasshopper specialist clades, and between phoretic and non-phoretic genera. We generated a mitogenomic phylogeny of the hypermetamorphic clade of Meloidae, including 21 newly generated complete mitogenomes. The phylogeny and estimated lineage divergence times were used to explore the association between diversification rates and changes in host specificity and phoresy, using State-Dependent Speciation and Extinction (SSE) models, while accounting for hidden factors and phylogenetic uncertainty within a Bayesian framework. The ancestor of the hypermetamorphic Meloidae was a non-phoretic bee-parasitoid, and independent transitions towards phoretic bee-parasitoidism or grasshopper specialization occurred multiple times. Bee-parasitoid lineages that are non-phoretic have significantly higher relative extinction rates and lower diversification rates than grasshopper specialists or phoretic bee-parasitoids, while no significant differences were found between the latter two strategies. This suggests that these two life strategies contributed independently to the evolutionary success of Nemognathinae and Meloinae, allowing them to escape from the evolutionary constraints imposed by their hypermetamorphic life-cycle, and that the “bee-by-crawling” strategy may be an evolutionary “dead end”. We show how SSE models can be used not only for testing diversification dependence in relation to the focal character but to identify hidden traits contributing to the diversification dynamics. The ability of blister beetles to explore new evolutionary scenarios including the development of homoplastic life strategies, are extraordinary outcomes along the evolution of a single lineage: the hypermetamorphic Meloidae.

An Overview of the Taxonomy and Geographic Distribution of Venezuelan Epicauta (Coleoptera: Meloidae)

et al. 2022

The incomplete knowledge of the species distribution ranges represents a serious barrier for many areas of study in Biology that goes from Systematics to conservation of Biodiversity. One of the most important available resources to deal with the lack of geographic information are scientific collections. Epicauta with more than 366 species described is one of the most speciose lineages within Meloidae. Almost 73% of its diversity occurs in America. In Venezuela, the tenth richest country in biodiversity of the world, only nine species of Epicauta have been recorded and most of them are known from one or two localities. The revision of the specimens of Epicauta held at the entomological collection of the Museo del Instituto de Zoología Agrícola "Francisco Fernandez Yépez" (MIZA) of the Universidad Central de Venezuela at Maracay, with additional data from other American and European collections allowed us to improve significantly the knowledge of the geographic distribution of the Venezuelan taxa. Besides, the morphological study of the specimens resulted in the addition of some species not previously recorded in Venezuela, the description of a new species, and the redescription of the almost unknown and forgotten species E. subvittata (Erichson 1848).

“…The nominate subgenus is widespread throughout much of the world (Pinto and Bologna 1999), and its 102 North American species have been studied in some detail (Pinto 1991). The subgenus Macrobasis LeConte, with 73 species distributed from southern Canada to northern South America (Pinto 1991;Campos-Soldini et al 2018), has never been adequately studied. The group is most diverse in southern Mexico.…”
