( Fig. 18 View FIGURE 18 )

Nephochaetopteryx marianae Dodge, 1968b: 423 View in CoL (key), 436 (description of male). Type locality: Panama, Canal Zone, Barro Colorado Island. Other references: Pape (1996: 261; catalog).

Type material examined. PARATYPE. ♁ ( SEMC): Barro Colo. Is., C.Z. / 12.II.1955 No. 834 / Carl W. 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]. [Paratype stored in a pinned plastic microvial.]

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 View FIGURE 18 ). Cercus elongate, slightly bent posteriorly and with a preapical rounded protuberance dorsally ( Fig. 18A View FIGURE 18 ). Cercal prongs convergent ( Fig. 18B View FIGURE 18 ). Surstylus triangular, slightly curved anteriorly, with rounded apex; setulae restricted to a band basally and setae concentrated on distal half ( Fig. 18A View FIGURE 18 ). 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 View FIGURE 18 ). 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 View FIGURE 18 ). Basiphallus shorter than distiphallus, gently curved dorsally ( Fig. 18F View FIGURE 18 ). Distiphallus club-shaped, with a sinuous ventral margin bearing a small claw-like projection ( Fig. 18F View FIGURE 18 ). Vesica angled with a triangular projection basally and a rounded protuberance distally in lateral view ( Fig. 18F View FIGURE 18 ). Apex of vesica with a rounded projection covered with microtrichia ( Fig. 18F View FIGURE 18 ). Inner process of vesica longer than wide ( Fig. 18F View FIGURE 18 ). 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 View FIGURE 18 ). Median stylus with a basal projection ( Fig. 18F View FIGURE 18 ).

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.
