Diagnosis (adapted from Cruz 2020)

NYMPH. Characterized by a combination of the following characters: 1) labrum rectangular, distal medial margin without shallow emargination, dorsal surface with 3 to 4 elongated and blunt medial setae near distal margin (Cruz 2020: fig. 4a); 2) hypopharynx with lingua subquadrangular, one medial protuberance, apical tuft of setae, length subequal to superlingua (Cruz 2020: fig. 4d); 3) maxillary palp long 1.5× length of galea-lacinia, segment II without apical constriction (Cruz 2020: fig. 4e); 4) labial palp with segment II with pointed triangular distomedial projection, laterally directed; segment III rectangular, distal margin almost straight (Cruz 2020: fig. 4f); 5) foreleg with dorsal margin of femur with one row of 11 short concave and blunt setae; claw 0.6–0.8 × length of tarsus, without row of denticles (Cruz 2020: fig. 5a); 6) posterior margin of the tergum IV with triangular and pointed spines in regular sizes (Cruz 2020: fig. 5b); 7) paraproct with marginal spines, posterolateral extension with triangular and pointed spines (Cruz 2020: fig. 5c).

Intraspecific variation of Apobaetis fiuzai

Nymph

THORAX. Light yellow, with short brown marks (Fig. 2A, I); lateral brown mark on pronotum; sublateral brown mark on mesonotum; basal half brown on forewing pads (Fig. 2G); brown mark partially covering the thorax (Fig. 2L); femur without mark (Fig. 2F, H).

ABDOMEN. Tergum V with lateral brown mark (Fig. 2A, C, G, I, L); terga I–X with light brown spots (Fig. 2A, C, E, L N); terga II and VI with medial brown mark, III–V and VII, VIII with brown spots (Fig. 2I); terga I–IX brown (Fig. 2L); terga I, II, VI, VII with medial brown mark, tergum VIII almost brown completely, tergum IX with lateral brown mark (Fig. 2G); sternum IX with brown mark on anterior margin (Fig. 2B, D); sternum VIII light brown, sterna VIII and IX with lateral brown mark (Fig. 2H); sternum X light brown (Fig. 2M).

Morphological variation

LENGTH. Claws 0.6–0.8× length of tarsus; body 2.1–2.9 mm.

Comments

Based on the study of the type material, records from Amazonas (Cruz et al. 2011), Roraima (Falcão et al. 2011), Rondônia (Boldrini & Cruz 2014) and Maranhão (Boldrini et al. 2012), are not A. fiuzai . In the type material of A. fiuzai the hypopharynx has lingua subquadrangular, with medial protuberance; maxillary palp 1.5 × length of galea-lacinia and posterolateral extension of paraproct with pointed spines. The specimens recorded as A. fiuzai from Amazonas, Roraima and Maranhão (described here as Apobaetis pasternakae sp. nov.) have lingua subcircular, without medial protuberance; maxillary palp 2.0 × or longer than galea-lacinia and posterolateral extension of paraproct without spines. The specimen assigned to A. fiuzai from Rondônia (described here as Apobaetis jaquelinae sp. nov.) has lingua subcircular, posterolateral extension of paraproct with blunt spines, and has claws with two row of denticles.
