[‚mig·ə·lō′mȯr‚fē]Mygalomorphae
a suborder of large spiders. The trunk and legs are hairy; each chelicera is subchelate and has an opening for the poison gland at the tip. The spiders, which are distributed in the tropics, hunt at night for insects, small frogs and lizards, and, sometimes, small birds. The most characteristic species are A vicularia avicularia, which is black and reaches a length of 5 cm, and Selenocosmia javanensis, which is reddish brown and reaches a length of 10 cm.
