Emended diagnosis

Males of N. tsere resemble those of N. samonellaacademy sp. nov. by having an embolus with an acute angulation to palpal organ axis, intermediate keel without undulation, presence of a median dorsal granular area, and absence of an apical keel. Nonetheless, N. tsere differ from N. samonellaacademy by having a comparatively more elongated distal to medial extension of the embolus, prolateral superior keel well developed, prolateral inferior keel developed, elongated, and slightly serrated apically, intermediate keel slightly serrated apically and disjunct, intermediate keel emerging between spermatic pore keels, and median dorsal granular area composed of spiky spicules extending only over prolatero-dorsal surface of bulb (distal to medial extension of the embolus comparatively shorter, prolateral superior keel developed, prolateral inferior keel well developed, short, and smooth, intermediate keel smooth and continuous, intermediate keel emerging below spermatic pore keels, and median dorsal granular area composed of rounded spicules extending only over dorsal surface of bulb in N. samonellaacademy ).

Type material

Holotype

REPUBLIC OF ECUADOR – Provincia de Morona Santiago • ♂; Parroquia de Morona, Río Blanco ; 2.35463° S, 78.15171° W; elev. 922 m; 4 Jul. 2019; J. Falcón-Reibán and A. Recalde leg.; MECN-AR, MECN-AR-450 .

Remarks

Peñaherrera-R. et al. (2023) identified the presence of an apical keel on N. tsere as the inferior border of the apical section of the prolateral embolus surface. Nonetheless, after a second examination, we can confirm the absence of this keel.
