Type material examined
“VENEZUELA: T. F. AMAZ. [Amazonas State]; Cerro de la Neblina; Camp XI 1450 m; 00°52'N, 65°58'W” “at stream; 26–27 February 5 l985; P. J. and P. M. Spangler, R. A. Faitoute; collector”. (1 Holotype MIZA, 15 Paratypes). “VENEZUELA: T. F. AMAZ.; Cerro de la Neblina; Camp X, 00°54'N, 60°2'W, 1690m, 12–13 February l985, W. Steiner” (16 paratypes). “VENEZ., T.F.A. [Amazonas State];C.d.l. [Cerro de la] Neblina; Base camp; 26–31 Jan. 1985; Flite [sic] intercept Pan; Trap” (1 paratype). “VENEZUELA: T. F. AMAZ. [Amazonas State]; Cerro de la Neblina; Camp X, 1690m; 00°54'N, 60°2'W; 12 February l985” “Small sunlit stream; leaf packs in falls; between boulders; W. E. Steiner; collector” (3 paratypes).
This species can be distinguished from all other described laraines by the following combination of characters: small size (ca. 4.5 mm), the presence of a shallow, wide, V-shaped groove across apical third of the pronotum (Fig. 53), and pronotum 1.3 mm long, and 1.5 mm wide, with posterolateral angles obtuse.
This species exhibits only minor variations in length, which ranges from 4.2 to 4.5 mm, and varies from a medium brown to light brown in color. Additionally, the parameres can be straight to slightly curved.
Distribution and habitat
This species is known only from the type locality at Cerro de Neblina, Amazonas State, Venezuela (Fig. 2), see genus description for detailed habitat information.
The Cerro de Neblina endemic species Neblinagena prima was the only laraine elmid species collected in association with Hypsilara royi.
