Key to Known Males of Myzomorphus

Galileo (1987) provided a key to males of M. gounellei , M. sparsimflabellatus , M. quadripunctatus , and M. scutellatus . At that time, males of M. herteli Gilmour, 1960 , M. amabilis ( Tippmann, 1960) , and M. flavipes Galileo, 1987 were unknown, and the male of M. poultoni was not examined. Later, Galileo and Monné (2003) figured and described the male of M. flavipes . Wappes et al. (2013) figured the male of M. amabilis without description.

Based on the examination of the holotype of M. poultoni , and figure of the male of M. amabilis in Wappes et al. (2013), we can now provide an updated key to males of the genus [males of M. herteli and M. n. sp. Bezark et al. in press, remain unknown]:
