Dietrich, C. H. & Dmitriev, D. A., 2007, Revision of the New World leafhopper genus Neozygina Dietrich & Dmitriev (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini), Zootaxa 1475, pp. 27-42 : 36

Neozygina obsoleta n. sp.

( Figs. 1M, 3M–N)

Diagnosis. Length of male 3.1 mm (approximate; forewings of holotype missing). Coloration and markings as in N. chiapensis . Pygofer ( Fig. 3M) with dorsal appendage obsolete, reduced to heavily sclerotized ridge that extends half distance to apex; ventral appendage arising near apex, short, slender, extended posterad the abruptly bent dorsad; distal lobe narrow, weakly sclerotized dorsally. Aedeagus ( Fig. 3N) with preatrium short; shaft in lateral view relatively broad and compressed basally with small dorsal teeth, gradually narrowed to midlength, distal half slender, tubular, strongly arcuate, with slender unpaired ventral preapical process; gonopore apical; apex with large unpaired distal spine extended ventrad.

Material examined. Holotype male, MEXICO: Guerrero, Iguala , 11 September 1939 (D. M. DeLong) [ INHS].

Notes. Placement of this species in Neozygina , despite the absence of a dorsal appendage on the male pygofer, is justified by the presence of macrosetae on the dorsal margin of the pygofer and by the coloration, which is indistinguishable from that of many other members of the genus. The aedeagus is unique among known species of the genus in having upaired apical and preapical posterior spines. The specific name refers to the obsolete dorsal pygofer appendage.
