Pettya Kirkaldy, 1906

Pettya Kirkaldy, 1906: 343 ; Evans, 1966: 272. Type species: Pettya anemolua Kirkaldy, 1906

Eutambourina Evans, 1942: 27

Description. Body large and robust, upper part of face, pronotum and scutum distinctly punctate, but pits much sparser than those in Musbrnoia Dworakowska, 1972 and Variolosa Cao & Zhang, 2013 . Head broad, as wide as or slightly narrower than pronotum, crown fore margin subparallel to hind margin. Ocelli consisting of elongated, crescent-shaped vestiges continuous with lateral frontal sutures. Face strongly convex in profile, anteclypeus ovoid, lorum large. Forewing with first and third apical cell broad, second apical cell narrowest, fourth apical cell almost as long as third, AA and AP present. Hind wing venation usual for Erythroneurini , RA vein present.

Abdomen with numerous pits, 2S abdominal apodemes very small in examined species. Without anal tube ap- pendage.

Pygofer well sclerotized, with some rounded membranous areas of different sizes, setosity rudimentary; without dorsal and ventral appendages. Subgenital plate surpassing hind margin of pygofer side, base fused with sternite IX, broadened subbasally and narrowing towards apex, with about 2 macrosetae subbasally near outer margin, with some rigid setae on distal half of ventral side, without marginal microsetae. Style with apical part club-like, basal part elongated, preapical lobe shifted apically, well protruded. Connective U-shaped, manubrium short but broad, central lobe absent. Aedeagal shaft tubular, usually with asymmetric processes; preatrium short.

Diagnosis. Male genitalia characters were described based on the new species and the drawing of the genital capsule of P. punctata ( Evans, 1942) . The male genitalia of the type species and the other previously included species, P. taedea ( Kirkaldy, 1906) , have not been studied. This genus is similar to Eldama Dworakowska, 1972 externally, but the pits on pronotum are larger and sparser, the subgenital plate is not pointed apically and has macrosetae subbsasally, and the preapical lobe of the style is much larger.

Distribution. Australia.
