Type material.

Holotype: ♂, Panama: Darién Province: Cuenca 156, Pinogana District, Darién NP, Río Pirre, Estacion de MiAmbiente en Rancho Frio; 8.09081°N, 77.74043°W; 73 m a.s.l.; 9-12.ii.2018; Malaise trap; A. Thurman leg.; MUPADI-005-T-2023 (in alcohol).

Diagnosis.

This new species, with a pair of apical phallic spines, would appear to be another member of the N. collata group of Keth et al. (2015), with similarity to N. anahua (Mosely, 1937) from Mexico, and N. kurtika Oláh & Johanson, 2011 from French Guiana. Unlike these species, N. embera sp. nov. Harris, Armitage & Ríos has a posterolateral process from segment IX and bifid inferior appendages.

Description.

Male. Total length 1.2 mm (n = 1), 17 antennal segments, wings and body brown in alcohol. Genitalia (Fig. 5 ). Abdominal segment VIII annular. Segment IX in lateral view anteriorly tapering to short upturned apodeme, posteriorly with medial lobe, distally rounded with posterolateral triangular process; ventrally with anterior and posterior margins incised mesally, posteriorly with thin lateral processes; dorsally truncate posteriorly. Segment X elongate, triangular in lateral view; in dorsal view tapering distally to rounded apex. Subgenital plate in lateral view narrow basally, ventral margin sinuate with lobes and points, apex with stout seta, upper margin straight; in ventral view rectangular, widening posteriorly with stout setae on distal margins, rounded laterally. Bracteole in lateral view narrow basally, widening distally to rounded apex; in ventral and dorsal views straight, narrow over length. Inferior appendage bifid, ventral arm narrowly triangular, dorsal arm ovate and same length as lower arm; in ventral view divergent and separated, lateral arms narrow over length, inner arms slightly triangular, rounded apically. Phallus in dorsal view tubular, wide basally and distally, bearing pair of stout spines apically, short paramere encircling shaft at midlength.

Distribution.

Panama: Darién Province ( Darién National Park).

Etymology.

This species is named for the indigenous Embera people of Darién Province, where the species was collected. The name is a noun in the genitive case.
