In addition, T. bombi sp. nov. differs from latter and similar species mentioned above by the male protarsi with two basal protarsomeres dilated. Etymology The name is derived from “ bombi ”, the Oromic term for beetle. Material examined Holotype ETHIOPIA : ³, Bale Mts , Harenna Forest , E Rira, alt. 3150 m , 06°44′51″ N , 39°46′40″ E , Feb. 2007 ( CSCHM , registration number ZSM _COL_2018_008). Paratypes ETHIOPIA : 1 ♀ , same data as for holotype ( CSCHM ). Description BODY LENGTH. 3.2–3.3 mm . PROPORTIONS (n = 2). PW/HW = 1.42–1.43; PW/PL = 1.45–1.47; PW/PBW = 1.24–1.25; EW/PW = 1.60–1.61; EL/EW = 1.24. COLOUR AND MICROSCULPTURE. As described in T. iridescens sp. nov. HEAD. Eyes moderately small, tempora 0.7–0.8 times as long as eyes. Antennae moderately short, proportions of the first four antennomeres as follows: 1/0.93/0.93/0.8; antennomeres 7–9 approx. 1.8 times as long as broad. In all other characters as described in T. iridescens sp. nov. PROTHORAX. As described in T. iridescens sp. nov. PTEROTHORAX. Elytra markedly broad. In all other characters as described in T. iridescens sp. nov. LEGS. Short and comparatively thin; protibia slightly dilated towards apex, almost straight, finely but distinctly grooved on external surface. Two basal protarsomeres of male dilated, dentoid at the inner apical border. MALE GENITALIA. EL/AL = 2.76 (n = 1). Aedeagal median lobe slender, in lateral view more markedly bent in basal half, almost straight near apical lamella, and shortly bent upward at apex; basal bulb and sagittal aileron moderately large. Endophallus with copulatory piece elongated, indistinctly limited ventrally, more strongly sclerotized dorsally. Distribution Known only from the type location, on the southern slope of the Bale Mts, in the Harenna Forest east of the village Rira, at an altitude of 3150 m .
