Cyrtodactylus consobrinus species complex

On the Southeast Asian island of Borneo, there has been a recent renewed focus on reptile taxonomy, as genetic data have demonstrated a high amount of unrecognized biodiversity. We herein advance this taxonomic trend by delimiting three distinct species within the Cyrtodactylus consobrinus species complex: C. consobrinus, C. kapitensis sp. nov., and C. hutan sp. nov. To do so, we use a combination of ddRADseq and single-locus data, and morphological data. Using genomic data, we test species and population boundaries within the consobrinus species complex and show minimal population structure but high species level diversity. Despite not finding uniquely diagnostic morphological characters to delimit the new species, we suggest a combination of characters that can be used to identify each lineage. Lastly, we use our data to comment on the status of C. malayanus, with indications that this lineage is also better considered a species complex. These data highlight the prevalence of unrecognized lineages on Borneo, many of which face threats due to increasing deforestation and other anthropogenic pressures.
