Discovery of Cyrtodactylus ziegleri Nazarov, Orlov, Nguyen Ho, 2008
During explorations conducted in lava caves within Dak Nong UNESCO Global Geopark, Dak Nong Province, Vietnam, from 2020 to 2023, we collected five specimens belonging to the genus Cyrtodactylus. Morphological and molecular analyses identified the population as C. ziegleri. This finding represents an important step in documenting the herpetofauna of Vietnam's lava caves.

Correction: Independent Transitions between Monsoonal and Arid Biomes Revealed by Systematic Revison of a Complex of Australian Geckos (Diplodactylus; Diplodactylidae)
How the widespread expansion and intensification of aridity through the Neogene has shaped the Austral biota is a major question in Antipodean biogeography.Lineages distributed across wide aridity gradients provide opportunities to examine the timing, frequency, and direction of transitions between arid and mesic regions.Here, we use molecular genetics and morphological data to investigate the systematics and biogeography of a nominal Australian gecko species(Diplodactylus conspicillatus sensu lato) with a wide distribution spanning most of the Australian Arid Zone (AAZ) and Monsoonal Tropics (AMT). Our data support a minimum of seven genetically distinct and morphologically diagnosable taxa; we thus redefine the type species, ressurrect three names from synonymy, and describe three new species. Our inferred phylogeny suggests the history and diversification of lineages in the AAZ and AMT are intimately linked, with evidence of multiple independent interchanges since the late Miocene. However, despite this shared history, related lineages in these two regions also show evidence of broadly contrasting intra-regional responses to aridification; vicarance and speciation in older and increasingly attenuated mesic regions, versus a more dynamic history including independent colonisations and recent range expansions in the younger AAZ.

Vertebrate-eating jumping spiders
In this paper, vertebrate predalion by jumping spiders (Salticidae) was revisited, taking into account incidents of this kind recently published in the scientific literature or on the internet. Our study revealed that vertebrate predation by salticids is more widespread than previously thought, geographically and laxonomically. Roughly ninety percent of all reported cases refer to predation on anurans (Hylidae and Ranixalidac) and lizards (Dactyloidae and Gckkonidae) by salticids from the subfamily Salticinac (Hyllus spp.. Phidippus spp.. and an unidentified species presumably related to Hasarius Simon. 1871). In the remaining cases, salticids from the subfamily Salticinac Paraphidippus cf. aurantius (Lucas. 1833) and Phidippus audax (Hcntz. 1845)) were observed attacking bird hatchlings (families Paridac and Trochilidae). weighing =4 6 times more than the spiders. In two instances, the spiders were observed biting the hatchlings, but only in one single case, a salticid was seen feeding on a hatchling.

Controllable load sharing for soft adhesive interfaces on three-dimensional surfaces
For adhering to three-dimensional (3D) surfaces or objects, current adhesion systems are limited by a fundamental trade-off between 3D surface conformability and high adhesion strength. This limitation arises from the need for a soft, mechanically compliant interface, which enables conformability to nonflat and irregularly shaped surfaces but significantly reduces the interfacial fracture strength. In this work, we overcome this trade-off with an adhesion-based soft-gripping system that exhibits enhanced fracture strength without sacrificing conformability to nonplanar 3D surfaces. Composed of a gecko-inspired elastomeric microfibrillar adhesive membrane supported by a pressure-controlled deformable gripper body, the proposed soft-gripping system controls the bonding strength by changing its internal pressure and exploiting the mechanics of interfacial equal load sharing. The soft adhesion system can use up to ∼26% of the maximum adhesion of the fibrillar membrane, which is 14× higher than the adhering membrane without load sharing. Our proposed load-sharing method suggests a paradigm for soft adhesion-based gripping and transfer-printing systems that achieves area scaling similar to that of a natural gecko footpad.

A new species of thick-toed gecko
Several specimens of Pachydactylus angolensis, a poorly known Angolan endemic gecko, have recently been collected in southern Angola, considerably increasing its known distribution range. Previous observations led to the hypothesis that two different morphological forms exist in the country-a coastal form and an inland form. Based on the morphological examination of historical and recently collected specimens, as well as on newly generated molecular data, we conducted a taxonomic revision of this putative species complex. The results support the separation of these two forms as two different species. The coastal form belongs to the nominotypic population, while the inland form is here described as a new species, Pachydactylus maiatoi sp. nov.. A brief comment on the biogeographical implications of this discovery is also provided. Keywords: Africa, biogeography, integrative taxonomy, reptiles, type specimens
