Genus Catalinia, gen. nov. (Scorpiones: Vaejovidae) is described from southern California, USA and Baja California, Mexico. The genus is composed of four species formerly placed in Pseudouroctonus: Catalinia minima (Kraepelin, 1911), comb. nov. (type species), C. andreas (Gertsch et Soleglad, 1972), comb. nov., C. castanea (Gertsch et Soleglad, 1972), comb. nov., and C. thompsoni, comb. nov. (Gertsch et Soleglad, 1972). Major diagnostic characters of Catalinia include a carapace with a very weak anterior indentation, a very stout metasoma with little or no tapering from segment I to V, and a mating plug with two partial bases. Evidence is presented suggesting …

A new vaejovid genus from Mexico, Franckeus, gen. nov., is described based on unique neobothriotaxy. Species placed in this genus are from the Vaejovis “nigrescens” group (previously called the “nitidulus” group). Six species comprise this new genus, distributed throughout Mexico (mainland as well as Baja California Sur): Franckeus nitidulus, F. rubrimanus, F. platnicki, F. minckleyi, F. kochi and F. peninsularis. A new species of the Vaejovis “nigrescens” group, Vaejovis davidi, sp. nov., is also described.

Hermaphroditism, Gynandromorphism, And Four Pectines: An Extreme Case Of Developmental Anomaly In Scorpions (Scorpiones: Vaejovidae), Rolando Teruel, José Guadalupe Baldazo-Monsivaiz
Euscorpius
In the present note, we describe in detail an aberrant anomalous specimen of the scorpion Mesomexovis punctatus (Karsch, 1879) (Vaejovidae). This strange individual is an adult and exhibits a combination of hermaphroditism, gynandromorphism, and pectinal duplication (i.e., presence of four pectines); the latter represents the first report ever made of such teratology. It was collected by the authors in northeastern Guerrero State, Mexico.

Name-Bearing Types Of Scorpions Deposited At The Institute Of Ecology And Systematics, Havana, Cuba (Arachnida: Scorpiones), Luis F. De Armas
Euscorpius
In the Institute of Ecology and Systematics, Havana, there are deposited 76 name-bearing types (holotypes, lectotypes, and syntypes) of scorpions belonging to 10 genera of the families Buthidae (Alayotityus, Centruroides, Microtityus, Rhopalurus, Tityopsis, Tityus) and Scorpionidae: Diplocentrinae (Cazierius, Didymocentrus, Diplocentrus, Heteronebo). Most of these materials are from the West Indies, mainly the Greater Antilles (Cuba, Hispaniola, Navassa, Jamaica, Puerto Rico), but several are from Mexico. The collection includes species described mostly by P. Franganillo Balboa (1930–1936), A. Moreno Bonilla (1938–1940), and L. F. de Armas and his collaborators …

Euscorpius
The Mexican scorpion Centruroides hoffmanni Armas, 1996 is redescribed, based on adults of both sexes. It is readily diagnosed by its medium size, dark brown two-banded tergites and brown marbling on carapace, appendages and metasoma, pectinal tooth counts, the shape of the female basal plate of the pectines, development of metasomal carinae, and shape of the telson and subaculear tubercle. The geographical distribution of this species ranges from southeastern Oaxaca to southwestern Chiapas, Mexico. It was originally compared with Centruroides thorelli (Kraepelin, 1891), but actually it seems to be closely related to C. infamatus (C. L. Koch, 1845) and C. …
Historical Diversification Of Montane Herpetofauna Within And Between The Sierras Of Mexico, Robert William Bryson Jr.
Historical Diversification Of Montane Herpetofauna Within And Between The Sierras Of Mexico, Robert William Bryson Jr.
UNLV Theses, Dissertations, Professional Papers, and Capstones
The Mexican highlands consist of four major mountain ranges spanning most of mainland Mexico. The evolutionary history of the Mexican highlands has been shaped by various geological and climatic events over the past several million years. The relative impacts of these historical events on diversification in montane taxa, however, remains uncertain. I used mitochondrial DNA data from three widely distributed species complexes of lizards as a model system to exemplify the potential roles of Neogene mountain formation and Quaternary climate change on timing and tempo of diversification across the Mexican highlands. My results suggested strong geographic partitioning of genetic variation …
