Scorpions are nocturnal arthropods that inject their venom through the victims' skin by stingers. By the envenomation, clinical manifestations in a wide spectrum may occur, including pain at one side and death because of severe cardiopulmonary or neurological abnormalities. Sometimes the victim cannot describe the insect or does not remember even being stung after the event. We present two case...

A new species of Tityus, subgenus Atreus (Scorpiones: Buthidae) is described from the Province of Pichincha in the Ecuadorian Andes. Ecuadorian scorpion fauna remains one of the less well studied among those of South America. Nevertheless, some comments are addressed about its remarkable diversity and high level of endemic elements.

Rhythmicities of acetylcholine (ACh) and acetylcholinesterase (AChE) were studied in the mouse, Mus booduga (Gray), following intramuscular injection of scorpion, Heterometrus fulvipes (C. Koch) venom. Envenomation inhibited the activity levels of ACh and AChE in all the tissues selected for experimentation. Control animals exhibited diel rhythmicity in ACh and AChE while envenomated animals sh...

Up to now, microtubules have been described in the spermatids of all the species studied. In annelids (Webster and Richards, 1977), insects (Friedlander, 1976 ; Godula, 1979), whip scorpions (Phillips, 1976), fishes (Zirkin, 1975), amphibians (Picheral, 1972 ; Sandoz, 1974), sauropsidae (Nagano, 1962 ; Nicander, 1967 ; McIntosh and Porter, 1967 ; Marchand, 1977 ; Maretta, 1977) and such mammals...
