Ecdyogymnurus
Figure: 146, 224
In addition to the Ecdyonurinae characteristics, the following combination of characteristics will identify the genus:
Larval Diagnosis
Larvae of Edcyogymnurus differ from all other genera of Ecdyonurinae except Leucrocuta by the combination of having fimbriate setae on the ventral surface of the maxillae (as in Fig. 51) and no interfacing setae on the caudal filaments (as in Fig. 101). Female larvae of Edcyogymnurus and Leucrocuta cannot be differentiated morphologically, but mature male larvae of Edcyogymnurus have well-developed eyes, separated by a distance less than the width of the median ocellus, whereas male larvae of Leucrocuta have small eyes that are widely separated. Also, Leucrocuta is exclusively Nearctic, whereas Edcyogymnurus is only found in the eastern Palearctic.
Adult Diagnosis
In males the combination of ventral spines, well-developed dorsolateral spines on the penes (Fig. 146), and eyes separated by a distance less than the width of the median ocellus will differentiate Edcyogymnurus from all other Ecdyonurinae genera.
Distribution
Eastern Palaearctic (Fig. 224).
