D i a g n o s i s: The genus Ampleris OPITZ and its 7 previously described species were made available in 2016 (OPITZ 2016). This work included a key to species. Ampleris cacuminis specimens key out to A. cava OPITZ, from which A. cacuminis specimens differ in characteristics of the male genitalia. In A. cacuminis, the phallic plates are longer and the phallic apex is more acuminate. D e s c r i p t i o n: Size: Length 4.5 mm; width 1.3 mm. Form: As in Fig. 317.
