Typhochlaena costae.
A new brazilian tarantula
Much species exploration is undertaken out of pure curiosity about the living world, so it is easy to understand why progress in some obscure taxa has been slow. Other groups, however, are so significant that neglect of their taxonomy is inexplicable. Theraphosidae is one such taxon.
The theraphosids include about one-third of the 2,693 documented species of mygalomorphs – tarantulas and funnel web spiders. In the intricate sub-webs of invertebrate animals in many terrestrial ecosystems these are "top" predators, making them of special interest to ecology. They have been used as model organisms in such diverse studies as molecular biology, biochemistry, pharmacology, ethology and biogeography, and they have a large and devoted following in the international pet trade. Yet their taxonomy, natural history and phylogeny remain incompletely studied.
Professor Rogério Bertani, of the Instituto Butantan, São Paulo, recently revised three theraphosid genera, improving our knowledge of their species diversity, phylogeny, and geographic and natural histories, and describing nine species as new. Although there were more interesting natural history stories attached to some of his other new species, I could not get past the sheer beauty of one, Typhochlaena costae. Its spectacular colouration, long golden setae (hairs) over the chelicerae (jaws), carapace and abdomen are chelicerae-dropping gorgeous.
