  Distinct pathophysiological mechanisms of Heterometrus laoticus and Lychas mucronatus scorpion venoms on cardiovascular and renal functions Abstract Background:    Heterometrus laoticus and Lychas mucronatus are widely distributed in Southeast Asia, yet their pathophysiological effects of both venoms remain poorly characterized due to low human fatality rates. This study compared their venom compositions and acute cardiovascular and renal effects. Methods:   Anesthetized male New Zealand White rabbits were monitored for blood pressure (BP), heart rate (HR), and renal clearance following intravenous administration of crude venom (0.5 mg/kg). Venom components were identified via LC-MS/MS, and hematological/biochemical parameters were assessed. Results:    H. laoticus venom induced a rapid, transient hypotension ( p < 0.05), followed by a mild, prolonged hypotensive phase (up to 120 min). Conversely, L. mucronatus venom elicited a biphasic response: ...

A New Species Description in the Genus Amaurobius C. L. Koch, 1837 from Türkıye (Araneae: Amaurobiidae)

Abstract

A new species in the genus Amaurobius C. L. Koch, 1837, Amaurobius izmirensis sp. n., is described based on the male sex from Türkiye. A detailed description, including characteristic features with photographs of the general appearance and male copulatory organ, are provided. Additionally, the distribution of the species within Türkiye is mapped.
