After Eight Years of Exploration: Exciting Discovery of Three New Gecko Species!

A recently discovered lizard has made waves in scientific circles. This tan-brown day gecko, native to Angola, is part of a group of species that have never been formally described before. The new species includes the large-spotted Namib day gecko, Rhoptropus megocellus, along with R. minimus and R. crypticus. These findings emerged from years of research in Angola’s southwestern deserts.

Javier Lobón-Rovira, a researcher from the Universidade do Porto, led the study with a team of experts. They looked closely at the reptiles in Angola as access to these areas increased. Lobón-Rovira noted, “Angola has recently emerged as one of the most gecko-diverse countries in mainland Africa.” Much of this progress is thanks to improved access and modern genetic techniques that have revealed previously hidden species.

Discoveries About the Geckos

From 2018 to early 2025, the research team collected samples and documented 14 new gecko specimens. They examined body shapes, scale counts, and color patterns, confirming differences that pointed to the presence of new species. Genetic analysis revealed these species form distinct groups, showing no shared genetic markers with their closest relatives.

The large-spotted gecko stands out due to its unique eye-like dark spots along its back, which help it blend into its rocky environment. This species prefers large granite boulders where it can quickly hide from predators. Its ability to thrive in this habitat is closely tied to its physical structure, which enhances its speed and agility.

Why This Matters

Understanding the habitat of these geckos is crucial. The ecosystems in southwestern Angola are diverse, with various microhabitats. This complexity allows different species to coexist without competing directly. For instance, R. minimus, a smaller gecko, has distinct physical traits that separate it from its companions.

The research highlights the importance of preserving museum specimens. These samples allow future researchers to verify species classifications. They also help track potential changes in populations over time.

The Bigger Picture

Recent findings indicate that Angola’s southwestern region may be a hotspot for small reptile diversity. In 2025, another team described a new species, Rhoptropus nivimontanus, further emphasizing the area’s significance. This ongoing research reflects the need for clear species names, which is essential for conservation efforts.

As more species are identified, the focus remains on understanding their specific habitats and how to protect them from threats like mining and tourism. Each discovery in this region sheds light on the unique adaptations of these geckos.

Looking Ahead

Expect more research into the boundaries of these species, particularly where different groups overlap. The potential for new discoveries is vast, as past records can now be revisited with advanced DNA techniques. Angola’s diverse terrains hold many secrets, and the stories of its day geckos are far from finished.
