Neozygina mandibulata   n. sp.

( Figs. 1L, 3J–L)

Diagnosis. Length of male 3.8 mm. Ground color stramineous infused with brown; face and sternum pale; mesonotal triangles and abdominal terga brown. Male pygofer ( Fig. 3J) with dorsal appendage arising near midlength, bifid, arms divergent at right angle, dorsal arm short and relatively wide, ventral arm elongate and serrate dorsally, extended beyond pygofer apex and curved mesad; ventral appendage arising preapically, very large, slender, areolate, curved dorsomesad; lobe between appendages rounded, weakly sclerotized. Aedeagus ( Figs. 3K, L) with preatrium well developed, shorter than shaft; shaft compressed, in lateral view broadly Ushaped, with pair of short retrorse preapical spines and pair of long basolateral processes slightly divergent from shaft distally, not extended to shaft apex; apex bluntly rounded; gonopore arising preapically on posterior margin.

Material examined. Holotype male, MEXICO: Guerrero, Chilpancingo , 25 October 1941 (DeLong, Good, Caldwell, Plummer) [ INHS].  

Note. This species has a branched dorsal pygofer appendage similar to that of N. quadricornis   , but differs in having the aedeagal shaft evenly recurved in lateral view and the distal processes very short. The specific name refers to the jawlike dorsal pygofer appendage.
