New Gecko Species Discovered After 8-Year Search
New Gecko Species Discovered in Angola After Eight-Year Search
Table of Contents
A unique brown gecko observed on Angolan granite has led to the revelation of three previously unknown species of day gecko. Researchers, led by Javier Lobón-Rovira, identified Rhoptropus megocellus, R. White Dan R. Cryptic, following extensive field expeditions from 2018 to early 2025. This finding underscores Angola’s significant biodiversity,notably within its herpetofauna.
Why Angola is a Hotspot for Gecko Diversity
Improved field access combined with advanced genetic analysis has revealed species previously obscured by superficial similarities. Angola’s southwestern region, specifically the coastal area of Namibe and its escarpments, presents a mosaic of microhabitats - granite, gravel, dried riverbeds – fostering the evolution of endemic lineages and allowing closely related species to coexist with minimal competition.
Meet the New Species
-
Rhoptropus megocellus – The “Eye Spot” Gecko
Characterized by dark, eye-like spots (ocelli) arranged along its back, sometimes fusing into a collar on the neck. Its gray to brown skin with orange reticulation provides camouflage on granite surfaces.This species is strongly associated with large, flat granite formations.
-
Rhoptropus least – The Smallest Namib Gecko
The smallest of the Namib geckos, featuring granite-like back spots.Males possess four precocal pores, and exhibit a more muscular build compared to related species like R. biporosus.
-
Rhoptropus crypticus – The Cliff Dweller
Found on steep, rocky cliffs along the north coast of Namibe, this gecko is distinguished by its unique tail and back scale patterns, including distinctive black markings. Males have more precocal pores than R. biporosus.
rigorous Identification Process
The team analyzed 14 museum specimens and newly collected samples, comparing physical characteristics like size, scale count, and color patterns. These observations were then validated through DNA analysis, utilizing both mitochondrial and core DNA, confirming that the three geckos represent distinct genetic groups. This ensures the observed differences are not merely variations but reflect basic genetic divergence.
