Zinga Dworakowska, 1972

Zinga Dworakowska, 1972: 398 . Type species: Zinga novembris Dworakowska, 1972

Description. Body size, shape and coloration similar to those of Baya Dworakowska , but face lighter, coronal suture indistinct, and without dark stripe on forewing. Ocelli vestigial, represented by pair of indistinct pits mesad of dorsal end of lateral frontal sutures; dorsal margin of face with pair of large, pale translucent areas. Pronotum with reticulate pattern as in Baya . Forewing venation as in Baya , hind wing venation usual for Erythroneurini , RA vein present.

Male 2S abdominal apodemes narrow, extended to sternite IV–V. Anal tube without appendages.

Pygofer side with two pigmented processes on dorso-caudal and ventro-caudal angles, arising from either outer or inner lobe, usually slim, hind margin membranous. Subgenital plate surpassing hind margin of pygofer side, base fused with sternite IX, widened subbasally, with about 2–4 small macrosetae near central outer margin, microsetae in row along outer margin and scattered on ventral side. Style slim, pointed apically, forming an angle subapically. Connective lamellate or U-shaped, manubrium short but broad, central lobe small to large. Aedeagal shaft tubular, apex with pair of lateral branches, each one bearing slim process, merged with each other subapically or not; dorsal apodeme narrow and long in lateral view, slightly expanded in caudal view; preatrium rudimentary to short; gonopore subapical on ventral side.

Diagnosis. In the original description of this genus, a significant character is the merged apical processes of the aedeagal shaft which form a closed ring. This condition also exists in Z. mayensis Dworakowska, 2011 , but the area of distal fusion of the processes is much shorter than in the type species. The new species described here has the aedeagal processes free distally and is otherwise very similar to the two previously described species of Zinga . Therefore, the distal fusion of the aedeagal processes does not consistently distinguish this genus from Baya Dowrakowska. More stable differences between these two genera are listed in the diagnosis of Baya .

Distribution. Australia; Papua New Guinea.
