On the Tityus stigmurus complex (Scorpiones, Buthidae)
Zootaxa, 2009The species included in the Tityus stigmurus complex as established by Lourenço are revised. The male of Tityus serrulatus Lutz & Mello, 1922 is redescribed. New diagnostic characters are given for T. kuryi Lourenço 1997, T. melici Lourenço 2003, T. serrulatus and T. stigmurus Thorell, 1876. Tityus lamottei Lourenço 1981 and T.

Journal of Proteomics, 2013
The scorpion family Chaerilidae is phylogenetically differentiated from Buthidae. Their venom components are not known, and the evolution of the venom components is not well understood. Here, we performed a transcriptome analysis of the venom glands from two scorpion species, Chaerilus tricostatus and Chaerilus tryznai. Fourteen types of venom peptides

Cost of venom regeneration in Parabuthus transvaalicus (Arachnida: Buthidae)
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2007Scorpion venom has many components, but is mainly made up of water, salts, small molecules, peptides, and proteins. One can reasonably assume that the production and storage of this complex secretion is an expensive metabolic investment. However, to date, no study has addressed the costs associated with the regeneration of venom by scorpions.

The Genus Centruroides (Buthidae) and Its Venom [PDF]
, 1978 In North America scorpions of medical importance belong to the genus Centruroides Marx (1889) of the family Buthidae (Simon, 1879) and the superfamily Buthoidea (Birula, 1917). The name Centururus is a synonym for Centruroides but the latter is correct as explained by Pocock (1920f), who is also quoted by Stahnke (1971).

Exploration of Refuge Preference in the Arizona Bark Scorpion (Scorpiones: Buthidae) [PDF]
Environmental Entomology, 2014 The ongoing difficulty in understanding how Centruroides sculpturatus (Ewing) uses the built environment has prompted this study in exploring refuge choices in a school environment and in laboratory behavioral assays. Radio telemetry tags were used at an urban site heavily populated with C. sculpturatus to track scorpions for a period of 21 d from 1 to

The Chromosomes ofRhopalurus(Scorpiones-Buthidae)
The Canadian Entomologist, 1957In a series of papers it has been shown thatTityuschromosomes are provided with one centromere at each end (2, 4, 5 and 6). Proofs of such a view were found in the behaviour of the chromosomes in the course of spermatogenesis in the widely distributed Brasilian speciesT. bahiensis(Perty).

Dated phylogenetic studies of the southernmost American buthids (Scorpiones; Buthidae)
Molecular Phylogenetics and Evolution, 2017A dated molecular phylogeny of the southernmost American species of the family Buthidae, based on two nuclear and two mitochondrial genes, is presented. Based on this study, analyzed species of the subgenus Tityus (Archaeotityus) are neither sister to the remaining species of the genus Tityus, nor are they closely related to the New World microbuthids ...

Notes on Tityus confluens Borelli, 1899 (Scorpiones: Buthidae) in Brazil
Zootaxa, 2005Records for Tityus confluens from nine localities in three Brazilian States are given. Although showing a wide geographic distribution in Argentina, Bolivia, Paraguay and Brazil, the species is infrequently sampled. Tityus confluens normally inhabits dry environments, Chaco in Argentina, Bolivia and Paraguay, and Cerrado and Pantanal Matogrossense in ...

Venom-spraying behavior of the scorpion Parabuthus transvaalicus (Arachnida: Buthidae)
Behavioural Processes, 2015Many animals use chemical squirting or spraying behavior as a defensive response. Some members of the scorpion genus Parabuthus (family Buthidae) can spray their venom. We examined the stimulus control and characteristics of venom spraying by Parabuthus transvaalicus to better understand the behavioral context for its use.

A new species of Ananteris Thorell (Scorpiones: Buthidae) from Colombia [PDF]
Zootaxa, 2007 Ananteris myriamae sp. nov. is described from the department of Meta, Colombia. This species is characterized, among other features, by the presence of two concavities in the anterior margin of the carapace, and six carinae in metasomal segment IV. With its description, the number of known species of Ananteris is raised to 59, five of which are present
