“…Based on a relaxed molecular clock model, this species diverged from mainland populations during the late Miocene (~7 mya), and shows the highest genetic isolation of the species in the saxatilis clade (Ramírez-Reyes et al unpublished data). The recovered species tree allows us to propose a more stable taxonomy for this clade, with a clear separation of P. homolepidurus and P. nolascoensis (as was recently proposed by Lemos-Espinal et al 2019), and some non-monophyletic lineages that were considered part of P. t. saxatilis (Phyllodactylus sp. in this study).…”

We describe a new species of leaf-toed gecko of the genus Phyllodactylus from María Cleofas Island, the smallest island of Tres Marías Archipelago, Nayarit, México. Genomic, phylogenomic, and morphological evidence support that the new species presents a unique combination of diagnostic characters. Morphologically, the new species has a high number of tubercles, head to tail (mean 47), longitudinal ventral scales (mean 61), and third labial–snout scales (mean 26). Gene flow tests revealed the genetic isolation of insular populations from mainland counterparts. In addition, we confirmed the non-monophyly of P. homolepidurus and P. nolascoensis, and we show that the taxon P. t. saxatilis is a complex; therefore, we propose taxonomic changes within the saxatilis clade. The discovery of this new insular endemic species highlights the urgency of continued exploration of the biological diversity of island faunas of Mexico.

“…The non‐sister positions of the mainland and insular lineages of P. homolepidurus despite their geographic proximity (Figure 1) suggest the occurrence of cryptic diversity in continental populations with respect to geckos on San Pedro Nolasco Island, Sonora. Currently, insular and continental populations are still considered P. homolepidurus (Rorabaugh, 2008; Enderson et al, 2009; Uetz et al., 2019), but see ( P. nolascoensis ; Lemos‐Espinal et al., 2019).…”

Genomic assessment of the Phyllodactylus tuberculosus complex (Reptilia: Phyllodactylidae) in America

Leaf‐toed geckos (Phyllodactylus) exhibit much cryptic diversity, at least in North America. However, the origins of Central American taxa and their relationships with North American congeners remain unknown. The P. tuberculosus species complex is ideal for evolutionary and biogeographic studies because its geographic distribution extends from northern Mexico to Costa Rica. We analyse ~2,500 nuclear loci obtained by the GBS genomic technique to test hypotheses of genetic isolation among taxa and estimate times of divergence using a relaxed molecular clock model, which constitutes the first hypothesis for the diversification of North and Central American phyllodactylids. Phylogenetic analysis recovers three main clades within polyphyletic P. tuberculosus: tuberculosus, magnus and saxatilis. ABBA‐BABA tests show moderate to low levels of gene flow within the latter two clades and yet genetic isolation in Central American lineages. The relaxed molecular clock model dates the age of the MRCA between the Central American and North American lineages to the beginning of the Paleocene (65 mya), suggesting an ancestral distribution in the proto‐Mexican region and the Chortis Block.

“…We determined the conservation status of each species from the IUCN Red List 2019-2 ( IUCN 2019 ), SEMARNAT (2010) , and Environmental Vulnerability Scores ( Wilson et al 2013a , b ; Johnson et al 2015 ). We determined the number of species found in Sinaloa that were shared with the four neighboring states using recent herpetofaunal check lists for Sonora ( Lemos-Espinal et al, 2019a ), Chihuahua ( Lemos-Espinal et al 2017 ), Durango ( Lemos-Espinal et al 2019b ), and Nayarit ( Woolrich-Piña et al 2016 ). We also included the Baja California Peninsula in this comparison, using Grismer (2002) and Hollingsworth et al (2015) as species lists, since it used to be contiguous with the states of Sinaloa and Sonora .…”

Sinaloa possesses a rich biota with unique characteristics due to its proximity to the northern deserts, the tropical lowlands of the south, and the temperate environments of the western slopes of the Sierra Madre Occidental in Mexico. However, threats to its environment makes understanding the biological diversity of Sinaloa crucial. A checklist of the amphibians and reptiles has been generated, and the conservation status of Sinaloa’s herpetofauna summarized with the aim of understanding the potential conservation or management needs. Sinaloa has 159 species of amphibians and reptiles, including 39 species of amphibians and 120 species of reptiles. The herpetofauna of Sinaloa has relatively few species of conservation concern at a global and national scale (IUCN and SEMARNAT lists), but Environmental Vulnerability Scores suggest that there might be greater conservation concerns for the Sinaloa herpetofauna. Families of particular conservation concern include Craugastoridae, Eleutherodactylidae, Ambystomatidae, Crocodylidae, Dactyloidae, Eublepharidae, Helodermatidae, Iguanidae, Phrynosomatidae, Phyllodactylidae, Colubridae, Natricidae, Viperidae, Cheloniidae, and Dermochelyidae.
