Fig. 62–66, 90
The species is unique in America in having the gonocoxite wide, straight, apically rounded, and parallel­sided along its length. Other species, such as H. guadeloupensis Malicky, H. hageni Banks, H. linabena, new species, and H. rentzi Denning & Blickle also have wide, nearly parallel­sided gonocoxites, but these are bent posteriad. Tergum X is undivided apically as in H. cubana, H. guadeloupensis, H. molesta, H. ramosi, H. sigillata, and H. tachira, but can be distinguished from these species by the hidden basimesal lobe of its gonocoxite when viewed laterally.
Male. Head: Antennal scape slightly shorter than eye diameter. Maxillary palp segments equally long, each segment as long as eye diameter. Cephalic warts rounded, strongly convex, about 2/3 as long as eye diameter, with dark golden­brown setae. Forewing golden­brown, length 4.0 mm. Sternum VI process absent.
Male genitalia (Fig. 62–66). Segment IX, in lateral view (Fig. 62), with anterior lobe triangular, oriented anterodorsad and located midlaterally on segment; anterodorsal margin nearly straight, anteroventral margin shallowly concave; in dorsal view (Fig. 63), with inner margin widely ellipsoid; in ventral view (Fig. 64), with small posterior process; apodemes apparently absent. Segment X, in lateral view (Fig. 62), oriented posteroventrad, nearly straight; proximal half with dorsal and ventral margins parallel, distal half slightly tapering toward narrowly rounded apex; in dorsal view (Fig. 63), proximally parallelsided, distally narrowing toward apex; apex without notch (Fig. 63); with about 10 pairs of about equally long megasetae in longitudinal group starting at midlength of segment; and 2 pairs of very long megasetae in longitudinal line starting at proximal half (Fig. 62). Superior appendage (Fig. 62) club­shaped in dorsal view, tubular in lateral view (Fig. 62, 63); curving posteriorly in dorsal view (Fig. 62). Primary branch of gonocoxite, in lateral view (Fig. 62), generally nearly straight and with parallel dorsal and ventral margins along its length; apex rounded in lateral view, slightly hooked in dorsal view (Fig. 62, 63); central part of primary branch about 1.3x as wide as height of central part of tergum X (Fig. 62); anterodorsal margin nearly straight, smooth; posteroventral margin nearly straight, slightly undulated; basimesal lobe minute, not visible in lateral view, triangular in ventral view (Fig. 64), and armed with about 9 dorsal megasetae (Fig. 64); with slightly undulating median margins; basal plate, in lateral view (Fig. 62), nearly straight, apex clubshaped; in ventral view, (Fig. 64) strongly pointing anteriorly. Phallus, in lateral view (Fig. 65), nearly straight along its length; ventral margin gently concave; anterior 1/5 nearly 1.5x broader than its central part (Fig. 65); in ventral view (Fig. 66), tapering toward midlength; phallobase apparently absent; endotheca strongly produced into dorsodistal lobe (Fig. 65); sperm channel divided into thick posterior and slender anterior parts; sclerotized posteroventral part wide (Fig. 65).
Holotype male: VENEZUELA: T.F.A. [Territorio Federal Amazonas = Estado Amazonas]: Camp VII, Cerro de la Neblina, 0°51'N, 65°58'W, 1800 m, 30.i–10.ii.1985, P.J. & P.M. Spangler, & R.A. Faitoute (NMNH, pinned).
Distribution. Venezuela (Amazonas).
Etymology. laneblina, derived from the type locality, Cerro de la Neblina. The name is to be treated as a noun in apposition.
