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.

Description BODY LENGTH. 2.5–2.8 mm (Ø = 2.65 mm , n = 15). PROPORTIONS (n = 10). PW/HW = 1.43–1.50 (Ø = 1.46); PW/PL = 1.42–1.51 (Ø = 1.48); PW/PBW = 1.20–1.26 (Ø = 1.24); EW/PW = 1.37–1.49 (Ø = 1.44); EL/EW = 1.30–1.37 (Ø = 1.33). COLOUR. As described in T. dodola sp. nov. HEAD. Tempora 0.5–0.6 times as long as eyes. In all other characters as described in T. dodola sp. nov. PROTHORAX. Pronotal base distinctly wider than apical margin, sides evenly rounded throughout, laterobasal foveae formed as tiny pits near basal margin. In all other characters as described in T. dodola sp. nov. PTEROTHORAX. First elytral stria indistinct but present on disc. In all other characters as described in T. dodola sp. nov. LEGS. As described in T. dodola sp. nov. MALE GENITALIA. EL/AL = 3.03–3.22 (Ø = 3.13; n = 6). Aedeagal median lobe moderately small, rather slender, in lateral view more markedly bent in basal half, ventral margin almost straight towards apex; apical lamella moderately long, very faintly bent upward at tip. Basal bulb and sagittal aileron moderately large. Endophallus with copulatory piece indistinctly delimited, in lateral view more markedly sclerotized on dorsal side near ostium. Distribution Known only from the southern slope of the Bale Mts, south, east and west of the village Rira, at altitudes of 2070–2690 m .
