Diagnosis
Very similar to the above-described T. dodola sp. nov. and T. adaba sp. nov., but base of pronotum distinctly broader than apical margin, and aedeagal median lobe larger and distinctly slenderer. The new species differs additionally from T. adaba sp. nov. by the lighter body colour and less iridescent elytra, and by the more markedly sclerotized endophallus. For comparison with the likewise similar species T. harenna sp. nov., see description of the latter below.
Etymology
Dedicated to Mr. Ingmar Harry, Freiburg, who kindly provided us with Trechus specimens for study, and who indicated to us the occurrence of this new species in the Harenna Forest near Rira.
