  Blinking without eyelids: first video-documented evidence of a blink-like reflex in Ophisops elegans (Reptilia: Lacertidae)

  Eyelids play a crucial role in protecting the eyes of vertebrates; however, certain reptile species, such as Ophisops elegans, completely lack movable eyelids. In this study, we present the first video-documented evidence of a blink-like reflex in O. elegans, captured through endoscopic field observations and corroborated by laboratory video analysis. The observed movement consisted of a brief convex deformation of the ocular surface, lasting approximately 0.3 s and resembling a blink despite the presence of a fixed transparent brille. This behavior was observed once in the field and twice under controlled laboratory conditions. We propose that O. elegans may employ subtle contractions of the ocular musculature to mimic the protective function of blinking. These findings indicate a novel compensatory mechanism in eyelidless lizards and underscore the need for further research into ocular adaptations among reptiles.

  A contribution to the biogeography and taxonomy of two anatolian mountain brook newts, neurergus barani and n. Strauchii (amphibia: Salamandridae) using ecological niche modeling

  Kurnaz, Muammer; Şahin, Mehmet Kürşat

  The Anatolian newt, Neurergus strauchii, is an endemic Anatolian species. Until recently, N. strauchii was represented by three subspecies. It has been discussed within a recent phylogenetic study in which the subspecies N. s. barani is recommended to be evaluated as a cryptic but distinct species. To address this subject, we aimed to discuss the niche differentiation between N. barani and N. strauchii using geographical and bioclimatic aspects. All georeferenced data of N. barani and N. strauchii were used to estimate the potential distributions of these species in the Anatolian Peninsula. To evaluate their ecological niche differentiation, point-based analysis and niche similarity tests were done. Ecological niche modeling outcomes demonstrated a significant niche differentiation between N. barani and N. strauchii. Moreover, since these species are distributed in the east and west of the Euphrates Basin, this river might be considered as a geographic barrier that can cause isolation for these species. Lastly, we demonstrated their potential distributions for future with several scenarios. Our findings strengthened the results of the recent phylogenetic study and indicated the necessity of handling “barani” taxa at the species level. Moreover, these results contribute, as a piece of evidence, to the biodiversity of Anatolia where another endemic species lives.

  Mediostoma izmirica sp. nov.: A new harvestman species (Arachnida, Opiliones, Nemastomatidae) from Turkey

  Snegovaya, Nataly Yu.; Kurt, Kemal; Yağmur, Ersen A.

  A new harvestman species of the genus Mediostoma Kratochvil, 1958, Mediostoma izmirica sp. nov., is described and illustrated based on males and females from İzmir Province, Turkey. Differences between the new species and other species of the genus Mediostoma are indicated. Scanning electron microscope photographs of its characteristic structures are also given.
