Length of male 2.9–3.5 mm , female 3.5 mm . Dull yellow mottled with brown, without areas of red pigmentation. Pygofer (as in Fig. 3X ) with dorsal appendage arising near midlength, bifid with arms widely divergent in lateral view, dorsal arm extended posterodorsad, ventral arm longer and more slender, extended along pygofer margin, not reaching apex; ventral appendage arising preapically, long, slender, curved dorsomesad; lobe between appendages broadly rounded, weakly sclerotized near apex. Aedeagus ( Fig. 3 AA) with preatrium short; shaft strongly compressed, in lateral view very broad, rectangular, gonoduct extended along posterior margin throughout length; apex broadly humped; distal processes arising adjacent to gonopore, extended ventrolaterad and curved mesad; paired ventral processes extended posterodorsad, weakly divergent from shaft and each other, apices overlapping those of distal processes. Material examined. Holotype male, MEXICO : Guerrero , Iguala , 25 October 1941 (DeLong, Good, Caldwell, Plummer) [ INHS ] . Paratypes : 1 male , MEXICO : Oaxaca , rt. 190 km #180, La Reforma , 800m , 16°23’56”N , 95°46’29”W , 7 November 2001 ( C.H. Dietrich , sweeping, 01-056-03) ; 1 male , 2 females , MEX- ICO: Durango , El Salto , 9 June 1964 ( L. A. Kelton ) [ CNC ] . Note. This species resembles N. quadricornis in having a similarly bifurcated dorsal pygofer appendage, but differs in the shape of the aedeagus, which is much broader, lacks an anteroapical lobe, and has the distal processes curved ventromesad rather than ventrolaterad.
