Geographic variation and sexual differences in the external and skull dimensions and the ratios between some variables were studied in 477 bats (218_??_ _??_, 229_??_ _??_, 30 sex-unknown) from 19 regional populations of<I>Miniopterus australis</I>TOMES, 1858, <I>M. paululus</I>HOLLISTER, 1913 and<I>M. solomonensis</I>MAEDA, 1982. The forearm length of the dried specimens tended to be a little shorter than that of the alcoholpreserved ones. The males were larger than the females in respect to the TL, GL, CBL, IL, CL, BW and TL/FL in<I>M. australis</I>, and in the TL and TL/FL in<I>M. paululus</I>. On the other hand, the males were smaller than the females in the FL/G, and UW/CBL in<I>M. australis. M. solomonensis</I>was significantly different from those of all the populations of the other species in most dimensions and the MW/IL.<I>M. paululus</I>had significantly smaller length measurements of the skull than the other populations. Geographic variation was observed in all of the characters examined in<I>M. australis</I>and<I>M. paululus</I>, except the MW/GL in the latter species.
