Diagnosis (adapted from Nieto 2006)

NYMPH. Characterized by a combination of the following characters: 1) labrum rectangular, distal medial margin without emargination; dorsal surface with 4 to 5 bifid medial spine-like setae near distal margin ( Nieto 2006: fig. 19); 2) hypopharynx with lingua subcircular, apical tuft of setae, length subequal to superlingua ( Nieto 2006: fig. 22); 3) maxillary palp short, length subequal to galea-lacinia; segment II without apical constriction ( Nieto 2006: fig. 23); 4) labial palp with segment II with slender triangular distomedial projection, apically directed; segment III triangular ( Nieto 2006: fig. 25); 5) foreleg with dorsal margin, anterior and posterior surface of femur without setae; claw I 0.7× length of tarsus I, with tow row of denticles ( Nieto 2006: figs 26–27); 6) posterior margin of the tergum IV with apex rounded spines ( Nieto 2006: fig. 28); 7) paraproct with marginal spines, posterolateral extension with apex rounded spines ( Nieto 2006: fig. 30).

Material examined

None, analysis based on literature and consultation of Dr Carolina Nieto.

Comments

Fundamental differences were found between the original description of A. kallawaya and the Brazilian specimen ( Boldrini & Cruz 2014). In the original description the labrum has dorsal surface with 4 to 5 bifid medial spine-like setae near distal margin; maxillary palp short, length subequal to galea-lacinia, and paraproct with posterolateral extension with apex rounded spines. The specimen of A. kallawaya from Rondônia (described here as Apobaetis luanae sp. nov.) has labrum with 4 simple medial spine-like setae near distal margin; maxillary palp long 2.0× length of galea-lacinia and paraproct with posterolateral extension without spines.

Distribution

Bolívia – Acheral, San Matías.
