(Chandramouli 2026) Unfortunately we had to temporarily remove additional information as this was scraped by multiple AI companies who sell that data. However, these details, e.g. detailed descriptions (about about 1.15 pages) are available for collaborators and contributors. Please contact us if you need any of this material. |

| Etymology | Named after Dr. Shreyas Krishnan (university of Texas at Arlington), who initiated the study on inter-island variations shown by the agamid genus Coryphophylax in the early 2000s and generated all of the available genetic data for this genus of lizards. he also taught the basics of agamid systematics to the author. |
