A team of scientists has identified a new species of frog in the forests of southeastern Madagascar, according to a study published September 1 in the journal SPIXIANA. The discovery was made during field surveys conducted in 2004 and 2023, where researchers were studying local reptiles and amphibians.
The newly discovered frog has been named Mantidactylus lovei, or Love’s giant stream frog. The species is notable for its size, measuring about three inches long, and its “stout” body with slightly textured skin. Researchers described its snout as “blunt” and noted that its mouth contains “small and sharp tooth serrations.” The frog’s brown coloring features darker spots on its back, line-like markings on its limbs and lips, and a pinkish-white stomach.
According to the study, these frogs have so far only been found near clear forest streams within low-elevation rainforests in the extreme southeast of Madagascar. “Love’s giant stream frogs have ‘exclusively been found in clear forest streams in intact or degraded low-elevation rainforest,’” the authors wrote. They observed the animals at night either sitting in or next to water.
Much about the new species’ lifestyle remains unknown. The researchers emphasized that further work is needed to better understand these frogs and encouraged additional efforts to find and classify other giant stream frogs in Madagascar.
The species was named after Bill Love, who is recognized for his work as a reptile enthusiast, photographer, and author focused on Madagascar’s amphibians and reptiles. “Researchers said they named the new species after Bill Love, a ‘reptile enthusiast, photographer and author,’ for ‘his contributions to the knowledge of natural history and herpetoculture of Madagascar’s amphibians and reptiles.'”
Identification of Mantidactylus lovei was based on DNA analysis along with specific physical characteristics such as glands, body proportions, coloring, and size. The research team responsible for this discovery included Miguel Vences, Jean-Baptiste Ramanamanjato, Aurélien Miralles, and Frank Glaw.
