Coloration: Head: pale yellow to orange; eyes black, silver, golden or black with silver areas; antennal segment I orange or brown; II, brown or orange basally and brown distally; III, pale yellow or pale yellow basally and reddish or brownish distally; IV, pale yellow or reddish basally and brown distally. Torax: pronotum orange or collar and calli paler and posterior lobe darker; mesoscutum and scutellum pale yellow to reddish; pleura pale yellow to orange. Hemelytron: yellow to reddish, in some specimens cuneus orange and reddish; membrane translucent; veins yellow to reddish. Legs: coxae pale yellow to orange; femora yellow or orange, in some specimens bicoloured; tibiae orange, apex yellow or brown; tarsi pale yellow; claws orange to brown. Abdomen: pale yellow to reddish, in some specimens with more than one colour. Surface: Shiny, posterior pronotal lobe evenly punctate; head, pronotum, and hemelytra with recumbent setae; labium with semierect setae; antennal segment I with abundant recumbent setae, II with recumbent and scattered semierect setae, III and IV with recumbent and semierect setae; veins with minute and recumbent setae; pleura and abdomen with longer semierect setae than dorsum; coxae, trochanters, femora, and tarsi with short, semierect setae; femora with dorsal setae as long as ventral setae; tibiae with abundant recumbent setae. Structure: Head: more than 2× as wide as long; clypeus not prominent, rounded in lateral view; frons rounded in lateral view; vertex flat, slightly longer than width of head; eyes large, stylate, more than half head height, upper margin attaining or overcoming dorsal margin of head, inner margin at level with lateral margins of collar; maxillary plates rectangular, medium to large; gula not visible to short; labium at least extending to mesocoxae; antennal segment I straight or slightly tapering towards apex; II, slightly widened towards apex, at least 2× as long as I; III, tapering towards apex, thinner than II; IV, straight. Torax: anterior margin of collar concave medially and posterior margin straight or convex; wider than antennal segment I; calli not evident to evident, separated, not ataining or ataining lateral margins of pronotum; posterior pronotal lobe with shallow depression separating humeral angles; posterior margin straight; mesoscutum exposed or not; scutellum in some species with a basal depression. Hemelytron with lateral margins slightly convex from apex of scutellum; embolium flat, in one species not bent upwards; medial fracture shorter than half of corium, anterior half adjacent to R + M vein, posterior half separated from R + M vein; R + M ataining or not cuneal fracture; cuneus longer than wide, inner margin concave; cell angled before apex of cuneus, inner and posterior margins straight. Legs: profemora widened basally, meso- and metafemora straight, metafemora slightly curved; protibiae with apex flatened, meso- and metatibiae straight. Male genitalia: Genital capsule wider than long; right wall shorter or longer than lef; dorsal wall well developed or reduced medially, posterior margin concave, with a large projection in lef margin; posterior margin of ventral wall sinuate or straight; subgenital plate in two species with two processes, lef one smaller and straight, and right longer and curved, with central depression. Lef paramere smaller than right, curved to strongly curved; with a distal concavity. Right paremere body flat and widened medially. Aedeagus small and simple; phallotheca membranous, some areas sclerotized; seminal duct sclerotized, folded initially, extending to half of phallotheca length; endosoma membranous.

Distribution: Brazil, Ecuador, Peru ( Fig. 9).

Etomologo: Te generic name is an anagram of Neella , a genus in which two of the species included in this new genus were originally described. Te gender is feminine.

Discussion: Naelle gen. nov. is recovered as the sister-group of Proneella and includes two species transferred from Neella , Neella itacoaiensis and Neella ecuatoriana , and a new as yet undescribed species. In our analysis this genus is recovered as monophyletic supported by four synapomorphies. Tree continuous characters: the relations, eyes height/head height (1: 0.055 –0.058), vertex width/eye width (5: 0.194 –0.204), and labial segment II/ total labial length (9:0.3); and one discrete synapomorphic character: lef paramere with a concavity at distal extreme (139:1). Te GC frequencies indicate a low support due to high contradictory information ( Fig. 7).

Naelle gen. nov. runs to the couplet 8 in the key to the Neotropical eccritotarsine genera ( Carvalho and Ferreira 1995) in which Hesperolabops and Aztecarina are identified. Hesperolabops includes species with the head with long eye stalks and hemelytra red or fuscous, and Aztecarina species have strongly stylate eyes, the pronotum narrowed and constricted anteriorly with the posterior margin strongly arcuate at middle, and the hemelytra punctate. Naelle gen. nov. has slightly stylate eyes, pronotum not strongly narrowed or constricted anteriorly and with its posterior margin straight, and yellow to reddish impunctate hemelytra.

Nine Neotropical genera are absent in the Carvalho and Ferreira (1995) 's key (see discussion under Globicephalomiris gen. nov.). Te combination of characters given in the diagnosis distinguishes Naelle gen. nov. from all other eccritotarsines.
