Remarks

Mycotretus episcaphoides resembles M. floriger ( Fig. 29F ) in body shape and morphology of male genitalia. The penile flagellum of M. episcaphoides is less sclerotized than that of M. floriger . Male genitalia of both species have a sinuosity at the anterior one-third of the flagellum virga. That sinuosity is strongly sclerotized in M. floriger and desclerotized in the examined M. episcaphoides . This morphology of the penile flagellum resembles that observed in M. chilensis Crotch ( Fig. 4F ) and M. trifasciatus Guérin ( Fig. 22A ) ( Pecci-Maddalena & Lopes-Andrade 2017).
