DIAGNOSIS: Cerci of Taenionema adults have multiple segments ( Fig. 369) which are characteristically short. The male genitalia is outlined with a sclerotized triangle ( Fig. 369). Male sternum 9 is long, surrounding the genitalia and cerci ( Fig. 369). The female subgenital plate extends over sternum 9 and over half of sternum 10 ( Fig. 370). Taenionema nymphs have a ventral triangular plate which reaches the abdomen apex ( Fig. 365). The nymphs lack coxal gills and dorsal abdominal processes, both characters of which are present in Taeniopteryx .
