Centruroides franckei, n. sp. and Centruroides rodolfoi, n. sp. are described from Oaxaca, Mexico. These species belong to the(striped) group within the genus. Thirteen species of the genus are reported for the state, six of them belonging to the (striped)group (infamatus-nigrovariatus subgroup). Both new species are compared to their most morphological similar species. A map with the six (striped) (infamatus-nigrovariatus subgroup) species in the state is also provided.

Species Delimitation and Morphological Divergence in the Scorpion Centruroides vittatus (Say, 1821): Insights from Phylogeography.
Scorpion systematics and taxonomy have recently shown a need for revision, partially due to insights from molecular techniques. Scorpion taxonomy has been difficult with morphological characters as disagreement exists among researchers with character choice for adequate species delimitation in taxonomic studies. Within the family Buthidae, species identification and delimitation is particularly difficult due to the morphological similarity among species and extensive intraspecific morphological diversity. The genus Centruroides in the western hemisphere is a prime example of the difficulty in untangling the taxonomic complexity within buthid scorpions. In this paper, we present phylogeographic, Ecological Niche Modeling, and morphometric analyses to further understand how population diversification may have produced morphological diversity in Centruroides vittatus (Say, 1821). We show that C. vittatus populations in the Big Bend and Trans-Pecos region of Texas, USA are phylogeographically distinct and may predate the Last Glacial Maximum (LGM). In addition, we suggest the extended isolation of Big Bend region populations may have created the C. vittatus variant once known as C. pantheriensis.

I received an email (04.21.10) with photos for confirmation of species from Matt L. in Alb. NM. We confirmed his pictures to Centruroides sculpturatus (gertschi form) from Sierra County, New Mexico. We compared the various characters between Centruroides sculpturatus and Centruroides vittatus.
Matt was gracious to allow his pictures on the blog.

Pseudouroctonus savvasi, n.sp., is described from specimens collected in two separate caves in the state of Coahuila, México,
though it does not exhibit any marked troglomorphies. It is most closely related to Pseudouroctonus apacheanus (Gertsch and Soleglad), from which it is clearly differentiated by size, the number of teeth on the movable finger of the chelicerae, hemispermatophore morphology and pedipalp chela morphometrics.

Pseudouroctonus sprousei sp. nov., from El Abra cave, in Coahuila, México, is described from a
single adult male. It is most similar to Pseudouroctonus reddelli (Gertsch and Soleglad), a well known
troglophile from Texas and Coahuila, which is also the type species for the genus
