Comments: This species was formerly described in the genus Heliria Stål, 1867 and then transferred to Telamona Fitch, 1851 ( Funkhouser 1927 ). Later, Goding moved it to Gelastogonia (1929) and lastly it was referred to Ennya by Metcalf & Wade (1965) . It does not belong to the genus Ennya based on the pronotum not concealing the forewings and the absence of carination. Instead, it presents the diagnostic characteristics of the subfamily Centronodinae Deitz, 1975 based the scutellum being concealed medially and forewing vein M with more than three branches reaching the margin ( Dietrich et al. 2001 ). However, the species does not have reticulate venation which is frequently present in Centronodinae . It is placed in the genus Centronodus Funkhouser, 1930 based on the produced suprahumeral angles ( Barreira & Sakakibara 2001 ). Metcalf & Wade (1965) only reported the species from Brazil , although Funkhouser (1951) also reported it from Ecuador .
