Remarks
|
|
A rare species. The full synonymy of Pyramica mutica was given by Wilson & Brown (1965) and Bolton (2000). Imai et al. (1985) reported this species from Indonesia. Its full distribution could extend widely in tropical Asia. P. mutica is found at forest margins extending to more open situations, nesting in soil or decaying wood.
