Systematic revision of the arboreal Neotropical ‘Thorellii’ clade of Centruroides Marx, 1890 bark scorpions (Buthidae c.l. Koch, 1837) with descriptions of six new species

Aaron Goodman, Lorenzo Prendini, Oscar Francke & Lauren Esposito
The arboreal Neotropical ‘thorellii’ clade of Centruroides Marx, 1890 bark scorpions (Buthidae C.L. Koch, 1837) is revised, using a novel approach to species delimitation. A phylogenetic analysis, based on 112 morphological characters and 1078 aligned DNA nucleotides from the mitochondrial Cytochrome c Oxidase Subunit I (COI) gene, provided the framework for placing singletons from geographically disparate localities (and often with suboptimal preservation) using COI minibarcodes, thereby enlarging the taxon sample for diagnosis and delimitation of...

Aposematic patterns shift continuously through the life of poison frogs

Michael Yuan, Catherine Jung, Rayna Bell & Jessica Nelson
Color and pattern are often dynamic traits that change throughout an individual’s lifetime. Still, long-term shifts in coloration have received limited attention. Dendrobatid poison frogs are a classical system in the study of color and pattern evolution in which both sexual selection and predation avoidance are thought to drive the evolution of color and pattern at the population and species level. Here, we highlight an overlooked axis of pattern diversity, within individual variation, using three...

Endemism, invasion, and overseas dispersal: The phylogeographic history of the Lesser Antillean frog, Eleutherodactylus johnstonei

Michael Yuan, Jeffrey Frederick, Jimmy McGuire, Rayna Bell, Struan Smith, Calvin Fenton, Jourdan Cassius, Rudell Williams, Ian Wang, Robert Powell & S. Blair Hedges
Cryptogenic species, those whose native and introduced ranges are unknown, pose a challenge not only to conservation but also to studies of ecology, biogeography, and evolution. One such species is the Lesser Antillean frog, Eleutherodactylus johnstonei, which is broadly distributed through the Caribbean and mainland South America. The Lesser Antilles pose a particular challenge with regard to cryptogenic species because these islands have been anthropogenically connected since before recorded history. We combined genetic (available on...
