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
.
