Elattoneura tarbotonorum Dijkstra, 2015
- scientific: E. frenulata sensu ??? nec (Hagen in Selys, 1860)
- vernacular: Angola Threadtail
Type locality: Lubango, Humpata, Angola
Male recalls E. cellularis and E. frenulata by (a) much of the body including the frons and most of the thorax, legs and abdomen being pruinose with maturity; and (b) the ventral process of the cerci ending in a single tip. However, (1) is notably more stout, Hw has 57-59 % length of entire body and reaches to base of S7, rather than 51-53 % and halfway S6; (2) the ventral portion, including metepisternum and metepimeron, is the blackest and most densely pruinose part of the thorax with a bold yellow stripe spared out down the full length of the metepisternum, running through the metastigma; (3) Fw and Hw Pt have rather acute distal corners, with the anterior and distal borders of similar length and distinctly longer than the posterior and proximal borders respectively, rather than the anterior and posterior borders being more similar and typically longer than the proximal and distal borders; and (4) the cerci have a more slender apex and an abruptly narrowed ventral process with a blunt rather than sharp tip.
Recorded from an open stream, but possibly also in gallery forest. Often with rocks. From 2000 to 2300 m above sea level, but possibly down to 700.
