Key to Species of Neozealides

1. Color of scutellar disc a continuation of scutal coloration, densely microtomentose; mesofrons with lateral gray stripe adjacent to golden brown ocellar triangle. Mesonotum ( Fig. 5 ) lacking dark brown longitudinal vittae but with 4 short, linear whitish gray marks, 3 medial of dorsocentral track and 1 laterad of dorsocentral track just anterior of level of postalar seta; 1 row of very short acrostichal setulae; wing ( Fig. 3 ) with 1 hyaline spot in cell R 1, 2 spots in cell R 2+3, cell R 4+5 with 2 spots, smaller spot basal, larger spot apical.............................................. N. irroratus (Tonnoir & Malloch) , n. comb.

- Color of scutellar disc distinctly darker brown than scutal coloration, often subshiny; mesofrons unicolorous, completely brown, with some faint golden brown microtomentum, lacking gray stripes laterad of ocellar triangle; mesonotum ( Fig. 6 ) with 3 longitudinal dark brown vittae, lacking gray marks adjacent to dorsocentral track; lacking row of acrostichal setulae; wing ( Fig. 16 ) with cell R 1 completely infuscate, 1 hyaline spot in cell R 2+3, cell R 4+5 with 3 spots, 2 small more basal spots and 1 larger apical spot................................................. N. obscurifrons (Tonnoir & Malloch) , n. comb.
