(Figs 9–31, 111)

Type species. Teratomyza neozelandica Malloch, 1933: 113, orig. des.

Diagnosis. Vertical callus not developed on head. One pair of katepisternal setae. Wing unicolorous. Vein R2+3 not approximated to costa (not even its middle section). Male subepandrial sclerite (Figs 10, 12) consists of two parts: the more ventral part is rather membranous broad U-shaped structure below epandrium, between caudal edges of surstyli, touching also bases of cerci; the more dorsal part is broadly bifid. Surstylus (Figs 11, 13) long with less broad base and without short thick blunt black teeth (pegs). Female sternite 8 (Figs 28, 30) broader than long with 2 pairs of long lateral caudal setae. Sclerotised duct of spermatheca thin and at least as long as spermatheca (Figs 29, 31).
