A CLADISTIC-ANALYSIS OF PROTODICTYA-MALLOCH (DIPTERA, SCIOMYZIDAE)

A cladistic analysis of the Neotropical genus Protodictya Malloch, 1993 was done using HENNIG 86. The genus Dictyodes Malloch, 1933 was used as the outgroup. The monophyly of Protodictya is supported by the medio-apical process of the fifth sternite of the male. Resulting from this analysis Protodictya is divided into two main clades. The first monophyletic clade includes P. chilensis Malloch, 19 33 and P. guttularis (Wiedemann 1830). The second clade consists of P. lilloana Steyskal, 1953, P. apicalis Steyskal, 1950, P. iguassu Steyskal, 1950, P. nubilipennis (Wulp 1897), P. brasiliensis (Schiner 1868), and P. bidentata (Marinoni and Knutson 1992).
