Eleven paralectotypes ( NHRS ): “Bogota // Lindig // Paratypus [print red label] // NHRS-GULI / 000105277” and NHRS-GULI000105278: GULI000105287 with same labels. Comments: Ennya notata was synonymized with E. dorsalis by Funkhouser (1927 , 1951 ), Goding (1929) , transferred to the genus Gelastogonia and included Oxygonia accuminata Buckton, 1903 as junior synonym, and lastly the species status was revalidated by Sakakibara (1996a) and transferred O. accuminata to synonymy under E. conica . The type locality is ambiguous (see comments under E. conspersa ). Ennya notata differs from E. dorsalis in having a blunt dorsal process and the central carina concolorous to the pronotum instead of acute and black respectively. It closely resembles E. conspersa (check the comments of E. conspersa ).
