  Acute gonadal toxicity induced by Bothrops atrox venom in mice Abstract Bothrops atrox is responsible for most snakebite incidents in the Amazon region. Its venom is recognized for causing significant tissue damage and systemic effects. However, its effect on reproductive organs remains poorly explored. This study aimed to investigate the acute effects of B. atrox venom on testes and ovaries of adult mice. Male and female mice were exposed to B. atrox venom (½ LD 50 ) via four administration routes subcutaneous (SC), intramuscular (IM), intravenous (IV), and intraperitoneal (IP), followed by comprehensive assessment of gonadal histology, sperm function, oxidative stress biomarkers, antioxidant enzyme activities, and mRNA expression of inflammatory and apoptotic markers. Following B. atrox venom exposure, ovarian histological architecture remained preserved across all routes, whereas testicular tissue exhibited route-dependent injury ranging from moderate luminal apoptosis aft...

Isometrus wenjieae sp. n., a new species of the subgenus Reddyanus from China (Scorpiones: Buthidae)

Abstract. – Isometrus (Reddyanus) wenjieae sp. n. from Guangdong Province (China), is described and properly illustrated. The new species shows a combination of distinctive morphological characters: (i) a total length ranging from 30.6 mm to 43.9 mm, (ii) pectinal teeth count 13 to 16 in males and 14 to 15 in females, (iii) fulcra present (iv) legs with markings, (v) ventral side of the subaculear tooth with two granules. A distribution map for the members of subgenus Reddyanus in China is equally provided.
