The Ecuadorian territory is divided into four natural regions: the coastal lowlands, the Andean highlands, the Amazon basin, and the Galapagos Islands. Each of these regions has its own ecosystems and specific vegetation. The purpose of this work is to compile an updated catalog of the Scarabaeinae (Coleoptera: Scarabaeidae) of Ecuador that includes distributional data and several nomenclatural acts. We compiled data from 25 scientific collections, with the examination of 13,550 scarabaeines; additionally, 390 bibliographic references were reviewed for their taxonomic histories. The Scarabaeinae fauna from Ecuador is represented by 33 genera and 223 species, with 45 range-restricted species; 27 species were erroneously recorded from the country. The following nomenclatural acts are made: (A) two new status as valid species: Canthon (Glaphyrocanthon) ohausi Balthasar, 1939,stat. n., and Deltochilum (Calhyboma) arrowi Paulian, 1939stat. n.; (B) one new synonym:UroxysmagnusBalthasar, 1940 =UroxyslatesulcatusBates, 1891,syn. n.; (C) two revalidated names: Canthidium (Canthidium) orbiculatum (Lucas, 1857) and Dichotomius (Luederwaldtinia) fortepunctatus (Luederwaldt, 1923); and (D) ten lectotypes designated for:ChoeridiumorbiculatumLucas, 1857;ChoeridiumcupreumBlanchard, 1846;CanthidiumcoerulescensBalthasar, 1939;CanthonangustatusHarold, 1867;CanthonangustatusohausiBalthasar, 1939;DeltochilumtessellatumBates, 1870;PinotusfortepunctatusLuederwaldt, 1923;PinotusglobulusFelsche, 1901;UroxyslatesulcatusBates, 1891; andUroxysmagnusBalthasar, 1940. The type specimens related to the new nomenclatural acts are illustrated and the maps of the geographical distribution of all species are provided.

“…Research on reptiles, amphibians and freshwater fish has shown varying levels of agreement with currently defined biogeographical boundaries in the Mexican Neotropics (Mateos et al, 2002; Suárez‐Atilano et al, 2014; Zarza et al, 2008). Although arthropods such as beetles played an important role in hypotheses concerning the origin and diversification of the Mexican biota (Morrone & Márquez, 2001), few studies have investigated the phylogeography or molecular phylogeny of arthropod taxa inhabiting the tropical deciduous forests of the Balsas Depression and the Pacific Lowlands provinces (Nolasco‐Soto et al, 2017; Pringle et al, 2012; Rengifo‐Correa et al, 2021).…”

Volcanism and palaeoclimate change drive diversification of the world's largest whip spider (Amblypygi)

The tropics contain many of the most biodiverse regions on Earth but the processes responsible for generating this diversity remain poorly understood. This study investigated the drivers of diversification in arthropods with stenotopic ecological requirements and limited dispersal capability using as a model the monotypic whip spider (Amblypygi) genus Acanthophrynus, widespread in the tropical deciduous forests of Mexico. We hypothesized that for these organisms, the tropical deciduous forests serve as a conduit for dispersal, with their disappearance imposing barriers. Given that these forests are located in a region of complex geological history and that they fluctuated in extent during the Pliocene–Pleistocene glacial/interglacial cycles we combine molecular divergence dating, palaeoclimatic niche modelling and ancestral area reconstruction to test if and when habitat fragmentation promoted diversification in Acanthophrynus. Concomitant with the expected role of landscape change, we demonstrate that orogeny of the Trans‐Mexican Volcanic Belt, in the Late Miocene or Early Pliocene (6.95–5.21 million years ago), drove the earliest divergence of Acanthophrynus by vicariance. Similarly, as expected, the later onset of glaciations strongly impacted diversification. Whereas a more stable climate in the southern part of the distribution enabled further diversification, a marked loss of suitable habitat during the glaciations only allowed dispersal and diversification in the north to occur later, resulting in a lower overall diversity in this region. Barriers and diversification patterns identified in Acanthophrynus are reflected in the phylogeography of codistributed vertebrates and arthropods, emphasizing the profound impact of Trans‐Mexican Volcanic Belt orogeny and glacial/interglacial cycles as drivers of diversification in the Mexican Neotropics.

“…Phylogeographic studies based on one nuclear (ITS2) and two mitochondrial (COI and 16S) loci resolved the Canthon cyanellus genealogy into seven clades from tropical regions of Mexico and one clade from Colombia [23,24]. Five of such clades were well supported while the remaining ones were not.…”

BackgroundWe used Illumina paired-end-sequencing to isolate and characterize microsatellites of Canthon cyanellus, a Neotropical roller dung beetle encompassing several lineages within its distribution range. Methods and ResultsWe examined C. cyanellus specimens collected at eight different localities in Mexico (two or three specimens per locality). We initially made ampli cation tests with 16 loci, but two of these showed ampli cation problems; thus, we evaluated 14 loci. The 14 microsatellites were polymorphic, with 2-16 alleles each. The expected and observed heterozygosity ranged from 0.11 to 0.76 and from 0.20 to 0.78, respectively. ConclusionsThese microsatellites will help to assess structure at the population and lineage levels, identify zones of potential hybridization between lineages, and draw a more precise geographic delimitation of Canthon cyanellus lineages.
