“…A third example is provided by C. chanae, in which divergence was evident between specimens separated by the Balsas Depression, an arid basin covering part of southwestern Guerrero and most of northwestern Michoacán in southern Mexico, which represents a barrier for other arachnid species [54][55][56][57]. Future studies should sample the entire ranges of C. chanae, C. hoffmanni, and C. schmidti to better understand the population structure within these species and investigate the possibility of additional cryptic species.…”

Systematics of the Arboreal Neotropical ‘thorellii’ Clade of Centruroides Bark Scorpions (Buthidae) and the Efficacy of Mini-Barcodes for Museum Specimens

Fragmented and degraded DNA is pervasive among museum specimens, hindering molecular phylogenetics and species identification. Mini-barcodes, 200–300-base-pair (bp) fragments of barcoding genes, have proven effective for species-level identification of specimens from which complete barcodes cannot be obtained in many groups, but have yet to be tested in arachnids. The present study investigated the efficacy of mini-barcodes combined with longer sequences of the Cytochrome c Oxidase Subunit I (COI) gene in the systematics of the arboreal Neotropical ‘thorellii’ clade of Centruroides Marx, 1890 bark scorpions (Buthidae, C.L. Koch 1837), the species of which have proven to be difficult to identify and delimit due to their similar morphology. The phylogeny of 53 terminals, representing all nine species of the clade and representative species belonging to related clades of Centruroides, rooted on Heteroctenus junceus (Herbst, 1800) and based on up to 1078 base pairs of COI and 112 morphological characters, is presented to test the monophyly of the clade and the limits of its component species. The results support the recognition of nine species of the ‘thorellii’ clade, in accordance with a recent taxonomic revision, and highlight the efficacy of mini-barcodes for identifying morphologically similar cryptic species using specimens of variable age and preservation.

“…Buthid scorpions of the genus Centruroides Marx, 1890 (Buthidae) are widely distributed in Mexican territory, from which 45 nominal species and two subspecies have been recognized (Ponce-Saavedra and Francke 2019), some of them with medical importance (Ponce-Saavedra and Moreno-Barajas 2005, Ponce-Saavedra and Francke 2013a, b, Ponce-Saavedra et al 2016, Quijano-Ravell and Ponce-Saavedra 2016).…”

“…Centruroideselegans (Thorell, 1876) and C.pallidiceps Pocock, 1902 were mentioned from Michoacán by Beutelspacher-Baigts (2000), but those records were seemingly based on misidentified specimens. The first one is only known from Jalisco and Nayarit; whereas the second species seems to be restricted to Sinaloa and Sonora (Ponce-Saavedra and Francke 2013a, b; Santibañez-Lopez et al 2016).…”

A new species of scorpion belonging to the genus Centruroides Marx, 1890 is described from the Coalcomán mountain range, western Michoacán State, Mexico. Its general aspect resembles Centruroidesruana Quijano-Ravell & Ponce-Saavedra, 2016, and C.infamatus (C. L. Koch, 1844), but it is a smaller species having lower pectinal tooth counts; also, males of C.ruana have the pedipalp chelae slightly thicker, whereas C.infamatus has a subaculear tubercle nearer to the base of the aculeus. Another species with similar aspect is Centruroidesornatus Pocock, 1902; however, a preliminary molecular analysis of the mitochondrial gene mRNA 16S showed genetic divergence (measured as p-distance) near to 10% between these species, and lower differences between the new species with respect to C.infamatus (4.63%) and C.ruana (5.07%). The molecular evidence together with the morphological characters (integrative taxonomy) are sufficient for recognizing the Coalcomán population as a separate and valid species.

“…Its Mexican representatives are a heterogeneous assemblage that has been repeatedly divided into discrete groups, subgroups and/or complexes of species, see e.g., Hoffmann (1932), Ponce-Saavedra & Moreno- Barajas (2005), and Ponce-Saavedra & Francke (2013). One of them is the "gracilis" species-group, represented in Mexico by four species: Centruroides fulvipes (Pocock, 1898), Centruroides gracilis (Latreille, 1804), Centruroides nigrescens (Pocock, 1898) and Centruroides nigrimanus (Pocock, 1898).…”

Herein we describe a new species of the Buthidae scorpion genus Centruroides Marx, 1890. It occurs at least in two small offshore islands of the southwestern Caribbean: Cozumel in Mexico and Guanaja in Honduras, based upon type specimens from the former and photographic evidence from the latter. It belongs in the "gracilis" species-group and is most closely related to both Centruroides gracilis (Latreille, 1805) and Centruroides nigrescens (Pocock, 1898).
