“…We tried to sample all the known distribution of Lanthanomelissa , including high and lowland grasslands. The genera Chalepogenus, Arhysoceble , and Trigonopedia were used as outgroups, since they are the closest relatives to Lanthanomelissa , according to the comprehensive analysis for the Tapinotaspidini tribe by (Aguiar et al 2020). We used specimens preserved in 95% EtOH, but also included pinned specimens collected less than 10 years ago for DNA extraction (Table S2).…”

“…Since there is no known fossil for Tapinotaspidini we used a secondary calibration point from the widely sampled phylogeny of Tapinotaspidini tribe (Aguiar et al 2020). The age of most recent common ancestor of Lanthanomelissa + Arhysoceble + Chalepogenus is 28 Ma (95% HPD 22.98-34.89).…”

“…Lanthanomelissa bees are endemic to the Campos of southern Brazil, Argentina, and Paraguay, including the Pampa and Subtropical Highland Grasslands. The tribe where it belongs – the Tapinotaspidini – originated in early Palaeocene savannas and diversified in open vegetation environments until conquering forests in Eocene (Aguiar et al 2020). Tapinotaspidini bees nest in the soil, as many other groups of bees who are intimately associated to open arid regions (Michener 1979), but they overcome the risks offered by humidity by the use of floral oils in nest lining (Aguiar et al 2004).…”

“…The species in this genus are widely distributed in Neotropical Region, always in open vegetation environments, but its highest diversity is found around Parana Basin in Southern South America, overlapping with the distribution of Lanthanomelissa bees, their main pollinators (Cocucci and Vogel 2001; Chauveau et al 2011; Chauveau et al 2012). The closest relatives of Lanthanomelissa are part of the genus Chalepogenus (Aguiar et al 2020) that explore plant species from the Nierembergia (Solanaceae) genus for oil and pollen (Cocucci 1991). The origin of Sisyrinchium and Nierembergia stem groups are close and estimated at about 13-20 Ma (Martins et al 2015).…”

Lanthanomelissa is a controversial taxonomic group of bees that was treated as subgenus of Chalepogenus or an independent genus. All of its species are endemic to the south-eastern grasslands of South America, an endangered and still poorly known environment. We aimed to understand the origin of this group of bees in time and space as well as the influence of Quaternary climatic fluctuations on its current distribution and possible link to the history of the Southern Grasslands. We inferred phylogenetic relationships of Lanthanomelissa species using 37 terminals and 3430 nucleotides of three mitochondrial and two nuclear markers and estimated divergence times and ancestral geographic range. We performed an ensemble with the algorithms SVM, Maxent, and Random Forest in a dataset of 192 georeferenced occurrence points using 19 WorldClim bioclimatic variables to analyse species distribution during the current and two past climatic scenarios (LIG, ∼120 kya and LGM, ∼21 kya). The results support the monophyly of the genus and taxonomic changes including the species Lanthanomelissa parva n. comb. on Lanthanomelissa, and the treatment of the goeldianus group of Chalepogenus as the genus Lanthanella. The genus originated at the Oligocene-Miocene border in the Chacoan-Pampean region, and the glacial-interglacial models indicated expansion in Last Glacial Maximum and retraction in Last Interglacial. Expansion and retraction of Lanthanomelissa distribution in the last glacial-interglacial indicated grasslands distributional shifts during periods of climate cooling and warming. The diversification of Lanthanomelissa supported the estimated expansion of southern grasslands in South America concurrently with the origin of Cerrado during the late Miocene. Their origin was approximately synchronized with their exclusive floral host, Sisyrinchium (Iridaceae).

A trait‐based approach to determining principles of plant biogeography

Lineage-specific traits determine how plants interact with their surrounding environment. Unrelated species may evolve similar phenotypic characteristics to tolerate, persist in, and invade environments with certain characteristics, resulting in some traits becoming relatively more common in certain types of habitats. Analyses of these general patterns of geographical trait distribution have led to the proposal of general principles to explain how plants diversify in space over time. Trait-environment correlation analyses quantify to what extent unrelated lineages have similar evolutionary responses to a given type of habitat. In this synthesis, I give a short historical overview on trait-environment correlation analyses, from some key observations from classic naturalists to modern approaches using trait evolution models, large phylogenies, and massive data sets of traits and distributions. I discuss some limitations of modern approaches, including the need for more realistic models, the lack of data from tropical areas, and the necessary focus on trait scoring that goes beyond macromorphology. Overcoming these limitations will allow the field to explore new questions related to trait lability and niche evolution and to better identify generalities and exceptions in how plants diversify in space over time.
