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 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 b, 19 c). Denticles of left mola not constricted. Maxilla (Fig. 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 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 e); setae on inner margin simple. Thorax. Hind wing pad. Present. Fore leg (Fig. 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 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 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 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 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 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).
