Nothing is known about the biology of Discothyrea yueshen.
Identification
Terayama (2009) - It is easily separated from Discothyrea sauteri described by Forel in 1912 from Pilam (=Taitung Pref.) by the 9-segmented antenna (8-segmented in sauteri). Rather it is resembling Discothyrea kamiteta from Okinawa island, the Ryukyus, Japan. However it is separated from the latter by the small eyes, short frontal lobe, weakly punctuated 1st gastral tergum, and a little smaller body.
