Brachistosternus paposo n. sp. and Brachistosternus barrigai n. sp. are described from Paposo, in the coastal transitional desert of northern Chile. Brachistosternus paposo n. sp. is closely related to Brachistosternus roigalsinai Ojanguren-Affilastro 2002, and B. barrigai n. sp. is closely related with Brachistosternus kamanchaca Ojanguren-Affilastro, Mattoni & Prendini 2007.

Background Scorpions are one of the most important medical arthropods in Iran. This study aimed to determine the fauna, spatial distribution and some morphological characteristics of these venomous arthropods in the study area. Methods Scorpions were collected using Ultra Violet light, rock rolling and digging methods in West Azerbaijan, East Azerbaijan, and Ardabil Provinces during 2015-2016...

Spiders can sense sounds in a frequency range between approximately 40 and 600 Hz by the use of hairs; they can detect e.g. the puff of wind of buzzing flies. On the contrary, scorpions use hairs as tactile sensors for obstacle avoidance. To integrate the advantages of both types of sensoric hairs, this article presents an artificial auditory-tactile sensor system, which combines the principles...

A key feature of the ancient body plan of scorpions is the pincer or chela. These multifunctional structures vary considerably in size and shape between different scorpion species. Here we provide the first comparative data on the pinching performance of the chelae of seven species of scorpions exemplifying the extremes of the shape range from slender to robust; Leiurus quinquestriatus, Androct...

A preliminary study on fossil scorpions found in amber, from the Lower Cretaceous through the Palaeocene and up to the Miocene is proposed. Scorpions remain rare among the arthropods found trapped in amber. Only 24 specimens are known from Cretaceous amber, representing eight families and subfamilies, ten genera and 21 species; in parallel, 10 specimens have been recorded from Baltic amber repr...

Molecular analysis of gut content is one the widest used methods to investigate diet in arthropods. Stomach some arthropods particularly difficult, e.g., arachnids, because they have external digestion and a low foraging frequency. Scorpions feeding frequency, their information scarce. In this work we explore DNA metabarcoding approach detect prey Vietnamese forest scorpions (Heterometrus laoti...

In this study, the epidemiology and clinical findings of scorpion stings in the Sanliurfa province of Turkey was evaluated between May and September 2003. Data obtained from questionnaires was evaluated and the identification of scorpions collected from the region was carried out in the laboratory. It was determined that of the species of scorpions only Androctonus crassicauda was collected. Th...

Information on the scorpions' fauna of Iraq is limited especially in Thi Qar Province. The scorpion specimens present study were collected from desert area which located between provinces and Al-Muthana (Al-Kata'a region). Scorpio kruglovi (Birula, 1910) redescribed this was found area.The diagnostic characters are given important features figured.

Scorpions represent an iconic lineage of arthropods, historically renowned for their unique bauplan, ancient fossil record and venom potency. Yet, higher level relationships of scorpions, based exclusively on morphology, remain virtually untested, and no multilocus molecular phylogeny has been deployed heretofore towards assessing the basal tree topology. We applied a phylogenomic assessment to...
