Rettenmey- er [printed and handwritten on rectangular white label] // From over swarm / raid of Eciton / burchelli // Paratype [printed on rectangular green label] // PARATYPE / Nephochaetopteryx / marianae / Dodge [printed and handwritten on rectangular white label bordered with red].

Additional material examined. Panama. Panama: Canal Zone, Barro Colorado Island, 28.III.1967, leg. R. G. Akre (1 ♁, WSU).
Redescription. Male. Length = 4.0– 5.6 mm (n = 2).
Head. Fronto-orbital and parafacial plates, gena and postgena with golden microtomentum. Postocular strip with silvery microtomentum. Frontal vitta reddish-brown. Six frontal setae. Palpus brown.
Thorax. Chaetotaxy: dorsocentrals 3+4 (first two weak); intra-alars 2+4; supra-alars 2+3, notopleurals 1 subprimary; anepisternals 5; merals 5. Mid femur with two median setae and without a posteroventral differentiated seta. Ctenidium consisting of three spines. Wing hyaline, with dark brown spot beginning in the terminal portion of vein R 1, filling the distal third of cell r 1 and the upper half of the distal half of cell r 2+3; vein R 4+5 setulose dorsally to crossvein r-m.
Abdomen. Tergites brown with a band of golden microtomentum on anterior 4/5 of dorsal and lateral surfaces. Sternites 1 to 2 light brown and sternites 3 to 4 dark brown; sternites with yellowish setulae and with marginal setae. Sternite 4 with a median patch of thick setae on posterior margin.
Terminalia. Sternite 5 brown with long and short slender setae; shallow cleft not surpassing the anterior margin of lobe; lobe rounded and with a tuft of short setulae; arm wider than long with rounded apex (Fig. 18E). Cercus elongate, slightly bent posteriorly and with a preapical rounded protuberance dorsally (Fig. 18A). Cercal prongs convergent (Fig. 18B). Surstylus triangular, slightly curved anteriorly, with rounded apex; setulae restricted to a band basally and setae concentrated on distal half (Fig. 18A). Pregonite with widened base and distal half perpendicular to base, with anterior margin bearing granulations and with grooves, posterior margin with a row of setae (Fig. 18C). Postgonite almost straight, short (shorter than pregonite) with pointed apex curved anteriorly and a long seta and some small pointed setae on anterior margin (Fig. 18D). Basiphallus shorter than distiphallus, gently curved dorsally (Fig. 18F). Distiphallus club-shaped, with a sinuous ventral margin bearing a small claw-like projection (Fig. 18F). Vesica angled with a triangular projection basally and a rounded protuberance distally in lateral view (Fig. 18F). Apex of vesica with a rounded projection covered with microtrichia (Fig. 18F). Inner process of vesica longer than wide (Fig. 18F). Lateral and median styli short, of about one-fourth width as the widest portion lateral wall of distiphallus, and both inserted medially in distiphallus (Fig. 18F). Median stylus with a basal projection (Fig. 18F).
Female. Unknown.
Distribution. NEOTROPICAL—Panama (Panama).
Remarks. This species is similar to N. utinguensis since it has pregonite with grooves and with granulations on anterior margin, apex of vesica rounded, covered with microtrichia, and arm of sternite 5 widened. However, it differs from N. utinguensis in having a brown palpus and distal half of vesica with a large, rounded projection. In N. utinguensis the palpus is brown and the projection of the vesica is small and triangular.
