Deep within the enchanting woodlands of Uganda, a peculiar and seemingly “dwarf”-like creature made its presence known. This enigmatic, expectant animal was found perched on a tree trunk, illuminated by the moonlight as it waited through the night – or at least, it tried to.
The pregnant creature, however, did not go unnoticed. Passing scientists, their curiosity piqued, stumbled upon this extraordinary find, ultimately leading to the revelation of a truly “cryptic” new species.
The fascinating journey to this discovery unfolded in the Karamoja region of central Africa, where a dedicated team of researchers embarked on multiple fieldwork expeditions in 2015. Their collective efforts culminated in a groundbreaking study published on September 23 in the Zoological Journal of the Linnean Society, shedding light on the remarkable Lygodactylus karamoja, affectionately known as the Karamoja dwarf gecko.
This remarkable species stands out among its gecko counterparts, earning the distinction of being “large” with a size of approximately 3 inches, as detailed in the study. It boasts a “slender” physique, marked by a “rounded” snout and adorned with several distinct “chevrons” adorning its throat.
Photographs capturing the essence of the Karamoja dwarf gecko reveal a creature with a brown body adorned with white spots running along its back. A lighter-colored variation of this gecko exhibits an almost marbled pattern of scales, a true testament to the marvel of nature. The gecko’s eyes are a deep brown, featuring a striking black circular pupil.
Beneath its body, the Karamoja dwarf gecko displays a mesmerizing array of yellow hues across its belly and groin. Notably, a pattern of U and V-shaped stripes decorates its throat, adding to its captivating appearance.
Researchers have aptly described the Karamoja dwarf gecko as possessing a “cryptic nature.” These elusive creatures have a strong affinity for trees, consistently found perched on their branches. They are most active during daylight hours, marking them as diurnal beings, although a unique discovery of a pregnant gecko was made during a night expedition.
The habitat of this newfound species is nestled within the woodland landscapes of “mid-elevation savannahs” within the Karamoja region. It is here that researchers chose to honor the local people and their culture by naming the species after the region it calls home—the Karamoja dwarf gecko, Lygodactylus karamoja.
Situated in northeastern Uganda, the Karamoja region shares its borders with South Sudan to the north and Kenya to the east, making it a vital area for biodiversity research.
Identification of the Karamoja dwarf gecko involved a comprehensive analysis of its size, color patterns, scale patterns, and other subtle physical characteristics, as elucidated in the study. Additionally, DNA analysis revealed that this new species exhibits a genetic divergence ranging between approximately 6% and 16% from other dwarf gecko species.
The research team, composed of scientists including Javier Lobón-Rovira, Aaron Bauer, Pedro Vaz Pinto, Jean-Francois Trape, Werner Conradie, Chifundera Kusamba, Timóteo Júlio, Garin Cael, Edward Stanley, Daniel Hughes, Mathias Behangana, Franck Masudi, Olivier Pauwels, and Eli Greenbaum, has not only unveiled the Karamoja dwarf gecko but also made the captivating discovery of four additional new species of dwarf geckos. These include a “large” mountain-dwelling gecko, a gecko boasting a striking “leopard-like” pattern, a gecko residing in a “unique” habitat, and a “large” forest-dwelling gecko.
In a world where the secrets of nature continue to unfold, the Karamoja dwarf gecko stands as a testament to the wonders that remain hidden within the heart of our planet.
