A pseudoscorpion clinging to a cave salamander: phoresy or failed predation?

  A pseudoscorpion clinging to a cave salamander: phoresy or failed predation? Abstract Pseudoscorpions are well known for phoretic associations with arthropods, but interactions with amphibians are rarely documented. Here we report a pseudoscorpion attached to the left palpebral region of an adult male Italian cave salamander, Speleomantes italicus , observed during a visual survey in a karst cave in Tuscany, Italy. The pseudoscorpion, assigned on the basis of visible morphology and locality to Chthonius cf. elongatus , was grasping a minute cutaneous fold on the lower margin of the left upper eyelid with one chela while the salamander moved slowly over the rock surface. No handling was performed and the initial contact between the two animals was not observed. The event therefore cannot be interpreted unambiguously, but may represent opportunistic phoresy or defensive attachment following a failed predation attempt. To our knowledge, this is the first published observation of a ...

A New Species of the Medically Important Scorpion Genus Hemiscorpius Peters, 1861 (Hemiscorpiidae Pocock, 1893) from Kurdistan, Iraq

Abstract

The scorpion genus Hemiscorpius Peters, 1861 is renowned for its medically important species, particularly Hemiscorpius lepturus Peters, 1861, the type species of the genus and only species previously recorded in Iraq. However, the scorpion diversity of the rugged, arid landscapes of the Kurdistan Region, especially Erbil Governorate, in northern Iraq, remains largely unknown. Extensive fieldwork in Erbil Province in 2024 resulted in the discovery of a previously unknown species, described herein as Hemiscorpius kurdistanus sp. n. The Halgurd-Sakran Mountains in the Bradost Region, to which it appears to be endemic, probably played a role in its speciation, providing a barrier that contributed to geographical isolation. The new discovery supports the hypothesis that Kurdistan represents an area of endemism for arthropods due to its isolation and unique environmental conditions. The addition of a new, potentially medically important scorpion species to the Iraqi fauna emphasizes the need for continued studies on the systematics of Hemiscorpius and other scorpion taxa as well as updated public health awareness and envenomation management strategies across the Middle East.
