Fluorescent Spider and Predatory Cricket Among Dozens of New Species Found in Angola

An expedition to Angola's remote Lisima Plateau has led to the discovery of dozens of new animal species previously unknown to science. Researchers from The Wilderness Project, focused on protecting Africa's large freshwater systems, explored the vast high-altitude region, which is a vital source for major African rivers like the Congo, Okavango, Zambezi, and Cuanza.

The Lisima Plateau, often called the 'water tower' of southern Africa, has seen limited scientific research due to decades of civil war and lingering landmines. However, previous studies indicated its significant ecological importance. The 'Cassai Life Atlas' project aims to meticulously document the biodiversity within the Cassai River basin and the plateau through macro photography and extensive fieldwork.

During a February expedition, a team of 16 international experts identified numerous new species. These include eight types of dragonflies and damselflies, three species of grasshoppers, and approximately 60 species of moths and butterflies. Notably, they found a new species of crab spider, tentatively named Smodicinus sp. nov., which exhibits fluorescence under ultraviolet light. While the exact function of this fluorescence is still under investigation, it is likely related to reproduction, hunting, or predator defense.

Further discoveries include a new species of orb-weaver spider, Paraplectana sp. nov., distinguished by its striking blood-orange color, which mimics ladybugs as a defense mechanism against predators. The team also identified a new species of armored predatory cricket. Expedition leader Rob Taylor expressed excitement about the discovery of armored crickets, describing them as "very cool."

Armored crickets are very cool.
