Figure 95. Biogeographical provinces of Mexico following the scheme of Morrone (2004, 2005), showing the distribution of the genus Ixchela. Red background colour indicates the Mexican Montane biotic component and its provinces: 1, Sierra Madre Occidental (no records of Ixchela); 2, Transmexican Volcanic Belt (species recorded in green); 3, Sierra Madre Oriental (species recorded in yellow); 4, Cuenca del Balsas (no records of Ixchela); 5, Sierra Madre del Sur (species recorded in dark blue). Yellow background colour indicates the Province of Chiapas (species recorded in light blue) which belongs to the Mesoamerican biotic component and is extended toward mountainous zones of Central America (Guatemala, Honduras, El Salvador and Nicaragua).
