Cryptophaea, a new euphaeid genus and three new species of Caloptera damselflies from Thailand (Odonata: Euphaeidae, Calopterygidae)

The euphaeid specimens from Doi Suthep (North Thailand) identified and redescribed by Asahina in 1987 as Schmidtiphaea schmidi are not conspecific with the holotype of S. schmidi Asahina, 1978, from Manipur (North-east India), but represent a distinct new species described as Cryptophaea saukra gen. & spec. nov. Bayadera vietnamensis van Tol & Rozendaal, 1995 and Schmidtiphaea yunnanensis Davies & Yang, 1996, are transferred to the genus Cryptophaea gen. nov. Anisopleura trulla spec. nov. from South Thailand is described and “Caliphaea confusa sensu Asahina, 1985“ from Doi Inthanon (North Thailand) is described as C. angka spec. nov.
