Figures 2 View FIGURE 2 c, 4 c, 19, 20, 30, 31b.

Diagnoses. NYMPH. A) Small body size (<5.0 mm); B) Body color pattern almost uniform, except for tergum I, bright yellow, and terga IX and X, blackish ( Fig. 2 View FIGURE 2 c); C) Labrum, medially, with single long seta ( Fig. 19 View FIGURE 19 a); D) Maxillary palp as long as length of galea-lacinia ( Fig. 19 View FIGURE 19 d); E) Inner margin of labial palp segment III distinctly shorter than outer margin ( Fig. 19 View FIGURE 19 e); F) Distal projection of fore femur short (not exceeding apex of femur, Figs. 20 View FIGURE 20 a, 20 b); G) Gills without medial rib, pointed at apex ( Fig. 20 View FIGURE 20 e).

Nymph. Lengths. Body: 4.4 mm; cerci: 2.2 mm; terminal filament: 2.2 mm; antenna: 2.2 mm.

Coloration ( Figs. 2 View FIGURE 2 c, 4 c). General coloration gray. Head yellowish-white, slightly washed with gray. Legs whitish. Terga. Segment I bright yellow; segments IX and X blackish. Sterna whitish; segments VI–VIII slightly washed with gray; segment IX heavily washed with gray. Filaments whitish.

Head. Labrum ( Fig. 19 View FIGURE 19 a). Length about 0.7 × maximum width; dorsal arc with single medial seta; ventrally with 8–9 spine-like setae near lateral margin.

Mandibles ( Figs. 19 View FIGURE 19 b, 19 c). Denticles of left mola not constricted.

Maxilla ( Fig. 19 View FIGURE 19 d). Medially with 1 spine-like seta + 6 apically pointed setae. Maxillary palp reaching apex of galea-lacinia; palp segment II 2.3 × length of segment I.

Labium ( Fig. 19 View FIGURE 19 e). Base of glossa poorly expanded (reaching less than 1 / 3 of paraglossa); inner and outer margin respectively with around 20 and 18 spine-like setae increasing in length apically; ventral surface scattered with apically pointed, fine, simple setae at base. Paraglossa dorsally with arc of 5 setae close to inner margin; ventrally with arc of 8–10 setae close to inner margin. Labial palp with segment I 0.8 × length of segments II and III combined; segment II dorsally with oblique row of 5–6 setae; segment III with distal margin slightly truncate; inner margin distinctly shorter than outer margin; ventrally covered with around 15 long setae ( Fig. 19 View FIGURE 19 e); setae on inner margin simple.

Thorax. Hind wing pad. Present.

Fore leg ( Fig. 20 View FIGURE 20 a). Ratio 1.7: 1 (0.7mm): 1.1: 0.3. Femur. Length about 5.5 × maximum width; outer margin with row of 12–14 clavate setae (length of setae about 0.1 × maximum width of femur); submarginal setae absent; anterior surface and inner margin with around 20 spine-like setae; posterior surface with around 5 scattered setae near inner margin; apex slightly projected ( Fig. 20 View FIGURE 20 b), apically with 2 clavate setae. Tibia. Outer margin with few simple setae; inner margin with two serrate setae on apex; subtending bristle blunt, extending apex of tibia ( Fig. 20 View FIGURE 20 c). Tarsus. Inner margin with row of 20 spine-like setae. Tarsal claw. 0.4 × length of tarsus.

Mid and hind legs. Similar to fore leg, except for the lower number of setae on anterior surface of femur.

Abdomen. Terga ( Fig. 20 View FIGURE 20 d). With spines present on posterior margin of segments II–X; larger spines on posterior margin 2.4 × longer than wide.

Sterna . With spines present on posterior margin of segments V–IX.

Gills ( Fig. 20 View FIGURE 20 e). Outer margin smooth; inner margin smooth; medial rib absent; tracheae extending from main trunk to inner and outer margins. Gill I reaching apex of segment III, asymmetrically lanceolate. Gill IV reaching distal margin of segment V, asymmetric, broad at middle, pointed at apex. Gill VII extending apex of segment X.

Paraproct ( Fig. 20 View FIGURE 20 f). With around 18 spines.

Cercus . With large spines on every four segments.

Terminal filament. Without large spines.

Male and female imago. Unknown.

Etymology. Lucifer , light-bringing in Latin. An allusion to the bright yellow coloration of abdominal terga I, which seems to be lighten.

Distribution ( Fig. 30 View FIGURE 30 ). Northeastern Brazil, Bahia State, Chapada Diamantina (part of Serra do Espinhaço), Parque Nacional da Chapada Diamantina.
