Figures 1 View FIGURE 1 d, 13, 14, 30.

Diagnoses. NYMPH. A) Large body size (> 7.0 mm); B) Body color pattern with distinct darker marks on abdominal terga ( Fig. 1 View FIGURE 1 d); C) Labrum, medially, with single long seta ( Fig. 13 View FIGURE 13 a); D) Maxillary palp short (around ¾ length of galea-lacinia, Fig. 13 View FIGURE 13 d); E) Inner margin of labial palp segment III subequal to outer margin ( Fig. 13 View FIGURE 13 e); F) Distal projection of fore femur long (distinctly exceeding apex of femur, Figs. 14 View FIGURE 14 a, 14b); G) Gills with medial rib ( Fig. 14 View FIGURE 14 e)

Nymph. Lengths. Body: 9.0– 9.5 mm; cerci: 4.0 mm; terminal filament: 4.5 mm; antenna: 3.5 mm.

Coloration ( Fig. 1 View FIGURE 1 d). General coloration yellowish-white profusely washed with dark brown. Head uniformly washed with brown, except below median ocellus. Legs yellowish-brown; tarsus darker. Terga. Segments IV and VIII less pigmented; segment IX with medial less pigmented area; segments II, III and VII sometimes less pigmented, but never as in segments IV and VIII; segments I–IX medially with a longitudinal unpigmented stripe. Sterna as in terga. Filaments yellowish-brown with a subdistal yellowish band.

Head. Labrum ( Fig. 13 View FIGURE 13 a). Length about 0.7 × maximum width; dorsal arc with single medial seta; ventrally with 8–10 spine-like setae near lateral margin.

Mandibles ( Figs. 13 View FIGURE 13 b, 13c). Denticles of left mola constricted at base (as in fig. 6f).

Maxilla ( Fig. 13 View FIGURE 13 d). Medially with 1 spine-like seta + 9–10 apically pointed setae. Maxillary palp 3/4 length of galea-lacinia; palp segment II 1.3 × length of segment I.

Labium ( Fig. 13 View FIGURE 13 e). Base of glossa expanded (reaching at least half of paraglossa); inner and outer margin respectively with around 20 and 15 spine-like setae increasing in length apically; ventral surface scattered with few short setae at base. Paraglossa dorsally with arc of 4 setae close to inner margin; ventrally with arc of 11 setae close to inner margin. Labial palp with segment I 1.0 × length of segments II and III combined; segment II dorsally with oblique row of 6–7 setae; segment III with distal margin slightly truncate; inner margin subequal to outer margin outer margin; ventrally covered with around 60 long setae; setae on inner margin serrate.

Thorax. Hind wing pad. Present

Fore leg ( Fig. 14 View FIGURE 14 a). Ratio 1.8:1(1.0mm):1.0:0.2. Femur. Length about 5 × maximum width; outer margin with row of 11–12 clavate setae (length of setae about 0.1 × maximum width of femur); submarginal setae absent; anterior surface and inner margin with around 35 spine-like setae; posterior surface with around 25 minute scattered setae near inner margin; distal projection exceeding apex of femur ( Fig. 14 View FIGURE 14 b), 0.2 × width of femur, apically with 4 clavate setae. Tibia. Outer margin with many simple setae; inner margin with two serrate setae on apex; subtending bristle blunt, not extending apex of tibia ( Fig. 14 View FIGURE 14 c). Tarsus ventrally with row of 16+1 spine-like setae. Tarsal claw. 0.2 × length of tarsus.

Mid and hind legs. Similar to fore leg, except for the lower number of setae on anterior surface of femur, subapical projections of femur less developed length of femoral projection and type of setae on inner apex of tibia (simple instead of serrate).

Abdomen. Terga ( Fig. 14 View FIGURE 14 d). With spines present on posterior margin of segments II–X; larger spines on posterior margin 3.0 × longer than wide.

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

Gills ( Fig. 14 View FIGURE 14 e). Outer margin serrated on distal 1/4; medial rib present; tracheae extending from main trunk to inner and outer margins. Gill I subequal in length to segment II, oval. Gill IV 1 1/2 length of segment V, asymmetric, broad at middle. Gill VII 1 1/2 length of segment VIII.

Paraproct ( Fig. 14 View FIGURE 14 f). With around 15 spines.

Cercus . With large spines on every two-segments.

Terminal filament. With spines on every four segments.

Male and female imago. Unknown.

Etymology. In honor of Dr. Rafael Boldrini, collector of the material from Santa Catarina (including that new species), friend and mayfly specialist.

Distribution ( Fig. 30 View FIGURE 30 ). Southern Brazil, Santa Catarina State, Serra Geral.
