摘要：The subfamily Micromygalinae is established for a new genus and species (Micromygale diblemma) from Panama that contains the world's smallest known mygalomorph spider, and the only one known to have only two eyes, a complete dorsal scutum in males, and no lungs. Cladistic analysis indicates that the species belongs to the Microstigmatidae but represents the sister group of all other known microstigmatids. The two previously recognized subfamilies of that group are therefore relegated to tribal status within the Microstigmatidae'--P. [1].
