If oceanic isl<strong>and</strong>s have been in isolati<strong>on</strong> l<strong>on</strong>g<br />

enough, some ancient col<strong>on</strong>ists have had opportunity<br />

to evolve into genera which are endemic (limited)<br />

to <str<strong>on</strong>g>the</str<strong>on</strong>g> isl<strong>and</strong>. Table 6 is a list <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g> 18 genera<br />

presently thought to be <str<strong>on</strong>g>Cuba</str<strong>on</strong>g>n endemics. However,<br />

most beetle genera in <str<strong>on</strong>g>Cuba</str<strong>on</strong>g> also occur elsewhere.<br />

Most <str<strong>on</strong>g>of</str<strong>on</strong>g> <str<strong>on</strong>g>the</str<strong>on</strong>g>se genera arrived at some time in <str<strong>on</strong>g>the</str<strong>on</strong>g><br />

past, <strong>and</strong> if <str<strong>on</strong>g>the</str<strong>on</strong>g> col<strong>on</strong>izati<strong>on</strong> was sufficiently l<strong>on</strong>g<br />

ago, <strong>on</strong>e or more col<strong>on</strong>izing species <str<strong>on</strong>g>of</str<strong>on</strong>g> each genus<br />

developed species level differences <str<strong>on</strong>g>of</str<strong>on</strong>g> its own, producing<br />

<strong>on</strong>e or more species endemic to <str<strong>on</strong>g>Cuba</str<strong>on</strong>g>.<br />

Additi<strong>on</strong>ally, some genera, possibly <strong>on</strong>es which<br />
