Ground color stramineous, heavily marked with brown; dorsum including crown and mesonotum mostly brown; head with genae, median area of frontoclypeus, and lateral margin of crown pale; forewing brown, veins pale. Male pygofer ( Fig. 4G) with dorsal appendage arising near base, nearly straight, tapered, apex bifid, not extended to apex of pygofer; ventral appendage arising preapically, short, extended dorsomesad. Aedeagus ( Figs. 4H, I) with preatrium absent; shaft tubular, in lateral view sinuate; paired subbasal processes extended nearly to apex, approximately paralleling shaft in posterior view, divergent from shaft in lateral view; distal processes arising laterad of gonopore, moderately short, slender, extended ventrolaterad; apex emarginate, with median dorsal spine extended dorsolaterad to left; gonopore apical.

Material examined. Holotype male, PERU: Madre de Dios, Rio Tambopata Res. , 30 km (air) SW Pto. Maldonado, 290m, 12°50’S, 069°17’W, 14 September 1984 (Smithsonian Institution Canopy Fogging Project, T. E. Erwin, et al., 01/02/54) [ USNM].

Notes. This species differs from other South American Neozygina in having the dorsal pygofer appendage bifid and the aedeagus with an asymmetrical unpaired distal spine. The specific name refers to the asymmetrical aedeagus.
