Importance and distribution

Polyschema comprises 20 species known on wide range of plants such as Platanus occidentalis (Platanaceae), Protea cynaroides (Proteaceae), Bruguiera gymnorhiza (Rhizophoraceae), Bruguiera parviflora (Rhizophoraceae), Kandelia candel (Rhizophoraceae), Sonneratia alba (Lythraceae), Schoenoplectus triqueter (Cyperaceae), Saccharum officinarum (Poaceae) and Acacia confusa (Fabaceae). Polyschema has also been reported from humans. Polyschema is distributed in Asia (China (Taiwan), Hong Kong), Caribbean (Cuba), South Africa, South America (Brazil) and the United States (Illinois, Texas). More collections of Polyschema are needed as molecular data is available for only four species.
