Elattoneura morini Legrand, 1985
Mealy Threadtail

Type locality: Djoumouna, DRC

Diagnosis

Male is similar to widely sympatric E. lliba 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 from (1) thorax largely pruinose; (2) dorsum of S8-10 and apex of S7 pruinose, rather than only dorsum of S9-10 being pruinose; (3) penis with drawn-out and pointed apical lobes; (4) ventral process of cerci with 1 tooth, rather than 2 apical teeth.

Habitat description

Mostly seeps and springs, but also (headwater) streams and possibly standing waters, shaded by forest. Often with coarse detritus and a soft (like muddy) bottom, probably especially calmer sections (like pools). From 0 to 800 m above sea level, but possibly up to 1500.
