We provide the first diversity assessment of Iranian species of the genus Asaccus based on COI DNA-barcoding. We analyzed 53 samples of Iranian Asaccus representing nine OTU corresponding to 10 currently recognzied nominal species, and evaluated both morphological and genetic data to support the recognition of a new species from Bandar-e Jask, Hormozgan Province, southern Iran-Asaccus authenticus sp. nov.

- Researchers have identified a new species named Cyrtodactylus thalang sp. nov. from Phuket Island, Thailand, within the Cyrtodactylus brevipalmatus group.
- The new species shows significant genetic and morphological differences from closely related species, indicated by a 14.7% to 15.1% variation in mitochondrial gene ND2 and distinct physical traits.
- The geographical analysis suggests that the brevipalmatus group originated in western Indochina, with speciation events occurring along the Tenasserim Mountains and subsequent dispersal across parts of northern Thailand, Laos, and Vietnam.
An integrative taxonomic analysis recovers a distinctive new species of the gekkonid genus Cyrtodactylus Gray, 1827 from Satun Province in extreme southern Thailand as the sister species to the Cyrtodactylus intermedius group of southern Indochina, approximately 600 km to the northeast across the Gulf of Thailand. Based on 1449 base pairs of the mitochondrial gene NADH dehydrogenase subunit 2 (ND2) and its flanking tRNAs, the new species, C. disjunctus sp.

We analyzed 93 genetic samples from the entire distribution of the Eremias fasciata species complex in Iran and surrounding regions, along with morphological data to support the description of two new species from Central Iran. We hypothesize that the diversification of the Eremias fasciata species complex was largely influenced by the fragmentation of sand massifs in the region.

- The Fergana Valley exhibits a high level of endemism, with 45 endemic plant species, 5 endemic insect species, and 5 endemic reptile species identified.
- Researchers discovered two new species of gecko in this area and conducted phylogenetic analyses to determine their evolutionary relationships.
- The survival of these unique species is threatened by agricultural development, highlighting the need for state protection in the form of designated conservation areas to safeguard the valley's ecosystems.
