FIGURE 172. Hypotyzed dispersion routes to current gryllacridines distribution. Fuchsia arrow, Gondwana connection (200-146 Ma.). Light brown arrow, transatlantic route (separation of South America and Australia), and black line show the first early connection with Oceanic mainland and its islands, the same arrow but punctuated give the possible Oceanic and Antartida connection (120-110 Ma.). Yellow arrow, transindian route, separation of Madagascar and Indian subcontinent (100- 90 Ma) and India subcontinent migration to north and introduction to Asia (95-30 Ma). Green arrows, colonization from South America to Central America and the Caribe Islands. Orange arrows, colonization from Indian subcontinent to Southeast Asia, China, Japan and adjacent territories. Blue arrows, colonization from Asia to Oceanic mainland and Island and vice-versa (the green, orange and blue colonization occur during the last maximum glacial 1 Ma. ago). The red punctuated line represents the Wallace line.
