"Despite her great work for natural science, she is poorly recognized when compared with male naturalists of that time," Fukushima explained. merianae, found only in Peru, was given its name in honor of the naturalist Merian. lynnae, can be found in Ecuador and Peru. The researchers also named three new species of spider in the Avicularia genus. rickwesti wrote in the journal Zoologia at the time that the species was quite different, anatomically, from other Avicularia spiders, but noted that it didn't fit in any other genus, either. Ybyrapora diversipes was once considered to be in the Avicularia genus, but new research establishes a new genus for this iridescent specimen from the Brazilian Atlantic rainforest. The spider is large and mostly reddish, with a distinctive red "oak leaf" pattern on its black abdomen. Finally, the scientists established a new genus called Antillena for a species of Dominican Republic tarantula identified in 2013 as Avicularia rickwesti. Researchers also moved two species of Caribbean spider that were previously in the Avicularia genus to a new genus called Caribena. Untangling the mess of Avicularia required creating a new genus, Ybyrapora, to encompass certain Brazilian spiders that dwell in rainforest trees, the scientists said. The scientists compared the anatomical characteristics of these old identifications with those of spiders from modern zoos and museums. The researchers had to track down ancient specimens from museums around the world, puzzling out original descriptions in Latin, French, Dutch, Portuguese and German. "The reasons to do this work were the necessity of solving the many problems of the genus (which were causing confusion to other genera, too), but also the chance to do something hard, big, important and new regarding tarantula taxonomy," Fukushima wrote.Īnd hard it was. Most Avicularia species grow around 5 or 6 inches (12 to 15 centimeters) in length, and many are popular pets for tarantula enthusiasts. Over the years, other scientists added more and more spiders to the genus, but no one ever had a good sense of what made a tarantula an Avicularia, other than that they are large and fuzzy, and live in trees, feasting on everything from insects to bats to small birds. He included three species in his grouping. In 1818, French naturalist Jean-Baptiste Lamarck, another influential name in early biology, took the first stab at describing Avicularia as a genus. The first Avicularia spider species was described in 1758 by Carl Linnaeus, the father of modern taxonomy himself. Merian's observation was disbelieved at the time, but Avicularia tarantulas really do eat birds, bats and other small vertebrates. A 1705 illustration by naturalist Maria Sibylla Merian shows a tarantula eating a bird.
