Figures 23-24

Material. 6♂, 1♀, upper Rio Mavaca (S of Base Camp) .

Female. So far undescribed. Head brown with black markings ( Fig. 23 ); rear of head chiefly black with four brown spots in the vicinity of foramen, and a broad pale margin along compound eyes. Pronotum brown with black markings on anterior and posterior lobes; shape of posterior lobe as in Fig. 24 . Color pattern of pterothorax similar to N. luz marina DeMarmels ( DEMARMELS, 1989a: Fig. 76). Legs pale except for outer side of femora and tarsi which are dark brown. Wings hyaline, pterostigma yellow. Venational characters as in male. Abdomen brown, segment 1 with a brown laterobasal spot; segments 2-6 with a dark brown transverse band close to distal end of tergum and with an additional dark spot latetally at the ventral distal angle; segments 8 and 9 with an incomplete black longitudinal line laterally parallel to ventral carina of tergite; segment 9 with three dark spots dorsally. Ovipositor (not including styli) reaching to distal end of segment 10.

Measurements. Total length 28.0; hind wing 16.5.

Remarks. The female was taken in tandem with a male. Many more specimens were seen flying under overhanging trees along the river bank. Tandems were ovipositing there into masses of small floating sticks. This is the first Venezuelan record of this species.
