Figures: 7A–7D

Diagnosis. This species belongs to the Neotrichia esmalda Species Group of Keth (2002). The male of Neotrichia makunaima sp. nov. is similar to that of Neotrichia feolai Santos & Nessimian 2009 , resembling this species mainly by tergum X, dorsally, with deeply incised and sclerotized apex; and subgenital plate posterior margin, in lateral view, bearing long patch of sclerotized spines on a membranous margin. However, in the new species, segment X, in lateral view, is not emarginate and has a hooked and slender apex, while in N. feolai the apex of tergum X, in lateral view, is deeply emarginate and has a rounded apex.

Description. Male (in alcohol): Dark brown species with length of each forewing 1.4 mm (holotype). Postoccipital setal warts pronounced, large, ovoid. Antennae each with 18 articles; scape normal, cylindrical, slightly longer than pedicel; flagellomeres of pedicel size, long, cylindrical. Maxillary palp formula I-II-IV-III-V (shortest to longest), first two articles extremely short, shorter than wide. Mesoscutellum anterior margin convex; metascutellum convexly subtriangular. Sternum VII without apicomesal process.

Male genitalia. Segment IX in lateral view subtriangular, anterolateral margins tapered, withdrawn into segment VIII; posteromesal margins slightly produced, each with membranous and oblong process bearing long posterior seta. Segment X membranous, bearing minute dorsal setae, with deep incision apicodorsally, two lateral lobes each narrowing to hooked and sclerotized apex. Subgenital plate, in lateral view, tongue shape, its posterior margin bearing pair of dorsal setae, a pair of ventral setae, and long patch of tiny sclerotized spines on membranous margin. Bracteoles spatulate, extending parallel with inferior appendages in ventral view and subequal in length. Inferior appendages setose, laterally narrow and rod-like. Phallus long with slight median constriction; slender, round, and posteriorly extending paramere; long process arising beyond base of paramere, darkening and tapering toward apex; phallic apex long and tubular, with membranous tip; ejaculatory duct long, apically protruding.

Female, larva, pupa, and egg. Unknown.

Holotype male. BRAZIL: Roraima: Mucajai municipality, RR-325, Vicinal Apiaú, Igarapé Serrinha (Sítio Vaca), 02°33’7.78”N / 61°18’45.06”W, 74 m a.s.l., 15 Dec. 2017, Pennsylvania light trap, J.L. Gama Neto leg. (alcohol; MPEG).

Paratype. 7 males, same data as holotype (alcohol; INPA) .

Distribution: Brazil (Roraima, type locality only).

Etymology. The epithet “makunaima”, a noun used in apposition, from the word Makunaimî in the Macuxi language, refers to a mythological figure of the indigenous peoples of Roraima.
