ABSTRACT-Four new species of myobiid mitcs are described from mammals from the Philippines:
Ugandobia saccolaimis sp. n., from Saccolaimz asasccolaimtts (Emballonuri dMeateab)i;nuncus obscuris
sp, n., from Hipposidero sobscurus (Hippesideri Pdtaeera)c;aru skervouli ssp. n,, from Kerivouta
hardwicki (iVespertili oannd i ldl(ayeeb)i ;aapomyos sp. n,, from Aporrry stittora (liMsurida eO)n,e new
subspecies, Ugtutdobi abalionycter libsyteens isssp, n., from Emballonura alecto (Emballonuri disae),
also describcd ,Apparent sexual dimorphism and precociou sdevelopment of female genita sltructures
were observed in the immature stages of the two Ugandobia mites.
