  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: ...

Two new species of Dysdera from Turkey (Araneae: Dysderidae)

Abstract

Two new species of Dysdera, D. metingurui sp. n. and D. turanguveni sp. n., are described based on male specimens from Kayseri (Central Anatolian Region) and Kahramanmaraş (Mediterranean Region) provinces of Turkey. Based on their somatic characteristics, both new species have mastidia on their chelicerae and belong to the ‘asiatica’ species group.
