E. tropica Ummerkutty, 1970 Pseudechinolaophonte minuta Cottarelli & Forniz, 1991, mordoganensis Kuru, Sönmez Karaytug, 2019 veniliae Cottarelli, Forniz Bascherini, 1992. longantennata Apostolov, 1990 had excluded analysis, due fragmentary imprecise description. Accordingly, ten remaining are clarified. is described as musa sp. Furthermore, subspecies armiger f. briani Lang, 1965 elevated rank 1965. A discussion provided key given.
