Four paralectotypes ( NHRS ): “Bogota // Lindig // Paratypus [print red label] // NHRS-GULI / 000105273” and NHRS-GULI000105274: GULI000105276 with same labels. Comments: Ennya nutans was considered a synonym of E. conica by Funkhouser (1927 , 1951 ). However, this species is significantly different: E. nutans has a blunt dorsal process directed forward while the dorsal process of E. conica is acute and directed upward. Ennya nutans resembles E. maculicornis in having an oblique dorsal process, but that process is considerably more slender in E. maculicornis than in E. nutans .
