Morphological and biological information are provided including photographs of the adult, genitalia, nymphs and host plants.

Among them, only three described reported respectively the genus from Myanmar, China, Taiwan species, Geisha distinctissima (Walker), Mimophantia maritima and Malaysia. So far, nine species were described in the genus Matsumura and Metcalfa pruinosa (Say) have previously been Salurnis, i.e., bipunctata (Walker, 1862), dilina Medler, 1992, recorded in Korea (Kwon and Huh, 2001; Lee and Wilson, dulitana Lallemand, 1939, estora Medler, 1992, granulosa 2010).
