Figure 1 in Re-discovery of the type series of the Indian freshwater mussel Parreysia corrugata (O. F. Müller, 1774) with the designation of the lectotype (Bivalvia: Unionidae: Parreysiinae)

Figure 1. Map of the Indian subcontinent (India and surrounding countries). The light green shading shows the Coromandel Coast, representing the vague type locality of Parreysia corrugata. The red star indicates Tranquebar (now Tharangambadi town), a former Danish colony on the Coromandel Coast, the name of which is written on the old (nineteenth century) labels of the type specimens. The map was created using ESRI ArcGIS 10 software (https://www.esri.com/arcgis); its topographic base was compiled with Natural Earth Free Vector and Raster Map Data (https://www.naturalearthdata.com) and Global Self-consistent Hierarchical High-resolution Geography (https://www.soest.hawaii.edu/ wessel/gshhg).
