Type species: Baya dymczata Dworakowska, 1972 Description. Body large and slim. Crown fore margin subparallel to hind margin, head narrower than or as wide as pronotum. Face convex in profile, anteclypeus broad. 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. Forewing with first and third apical cell broad, second apical cell narrowest, fourth apical cell almost as long as third. Hind wing venation similar to that of Elbelus Mahmood , submarginal vein reduced, terminated at the connection with CuA, CuA’’ absent, RA vein present. Anal tube sclerotized, without appendage. Pygofer well sclerotized, caudal margin very short, ventral margin oblique and with short lamellate processes or protrusions from both outer and inner sides; setosity poorly developed. Subgenital plate surpassing hind margin of pygofer side, outer margin slightly widened subbasally then gradually narrowing towards apex, apical part pigmented, with 1–2 macrosetae near inner basal angle, with or without macrosetae near central outer margin, marginal microsetae reduced, with some microsetae scattered on ventral side. Style with apical part slender, bent in right angle, preapical lobe small. Connective U-shaped, manubrium short but very broad. Aedeagus almost horizontal, shaft provided with very wide lateral lamella which extended ventrad, with pair of well-developed branched apical processes; dorsal apodeme narrow and long in lateral view; preatrium very short; gonopore central or subapical on ventral side. Diagnosis. This genus is similar to Zinga Dworakowska , but the forewing has a brown longitudinal stripe, the hind wing has a reduced submarginal vein and lacks CuA’’, the subgenital plate has 1–2 macrosetae near the inner basal angle and the aedeagal shaft has a pair of wide lateral lamellas. Both genera also have a pair of large, pale translucent areas on the anterior margin of the head at the transition between crown and face. Distribution. Papua New Guinea .
