A new scorpion species is described from the Spring Mountain Range near Las Vegas, Nevada. The new species appears to be geographically isolated from other closely related species of Uroctonites Williams & Savaryand Pseudouroctonus Stahnke. We tentatively place the new species in Pseudouroctonus and provide detailed descriptions and illustrations of type material. We compare the new species to ...

many reports have indicated the medical importance of animal poisons in iran. the significance numbers of iranians are injured from high endemic to sporadic, by venomous snakes, scorpions, wasps, bees, fire and velvet ants, spiders and backswimmer bugs, so their nuisance prevention is an important task.

Animal venoms have evolved many times. Venomous species are especially common in three of the four main groups of arthropods (Chelicerata, Myriapoda, and Hexapoda), which together represent tens of thousands of species of venomous spiders, scorpions, centipedes, and hymenopterans. Surprisingly, despite their great diversity of body plans, there is no unambiguous evidence that any crustacean is ...

Background Scorpions are among the world's venomous arthropods, they sting humans every year, suffering painful symptoms or losing their lives because of the venom. Odontobuthus doriae Thorell 1876 (Arachnida: Scorpionida: Buthidae) is a scorpion of medical importance and therefore its geographical distribution in Isfahan Province has been studied. Methods This descriptive cross-sectional stu...

The male of Megacormusgranosus is described for the first time and the female redescribed. A homology scheme proposed recently is applied to hemispermatophore structures. The specimens were collected in an oak forest from Pico de Orizaba Volcano at an average altitude of 2340 m. All adult males were collected by pitfall traps, whereas all adult females and both sex immatures were collected usin...

After about 3 hours, exhausted by crying and probably relieved...

The structure of the median and lateral eyes of the scorpion and the nature of the electroretinogram (ERG) have been described elsewhere, as has been the basic arrangement of apparatus used in the electrophysiological aspects of this study (Machan, 1966, 1967). The position of the shielding pigment in scorpion eyes has been shown to play a role in the general sensitivity of the eye (Machan, 196...
