Elattoneura lliba Legrand, 1985
Eastern Stream Threadtail

Type locality: Makokou, Mezalé River, Gabon

Diagnosis

Male is similar to widely sympatric E. morini by (a) found at shaded rainforest streams and swamps; (b) body becomes black and/or pruinose with maturity; (c) frons black, not pruinose; (d) eyes largely dark in life; (e) pruinosity extends over full width of mesepisternum and concentrated on S9-10, sometimes extending to S7; (f) apical process of paraprocts short, paraprocts therefore distinctly shorter than high. However, differs by (1) pruinosity concentrated on anterior 2/3 of mesepisternum; (2) only dorsum of S9-10 pruinose; (3) penis without distinct apical lobes; (4) ventral process of cerci with 2 closely placed apical teeth (best seen in caudal view).
