Trechus bastianinii Magrini & Sciaky, 2006: 183 ; locus typicus: Prov. Bale, Monte Batu, alt. 3100– 3600 m.

Trechus bastianinii – Ortuño & Novoa 2011: 136.

Type material

Not studied. Identification is based on the detailed description including figures of habitus and genital characters, and on additional material collected at the type locality.

Material examined

ETHIOPIA: 4 ³³, Oromia, Bale Mts, river valley above Goba, alt. 2990 m, 06°56′08″ N, 39°57′20″ E, Feb. 2007 ( CAF, CSCHM).

Identification

Similar to the sympatric and syntopic species T. oromiensis , however, easy to distinguish due to presence of two discal setae on each elytron. Other species of that region differ by having smaller eyes ( T. clarkeianus ), smaller body size and only one protarsomere of male dilated ( T. relictus ), or outer quarter of pronotal base more markedly bent anteriorly ( T. baleensis , T. batuensis , T. ericalis , T. fisehai sp. nov., T. wiersbowskyi sp. nov.). For comparison with the very similar allopatric species T. colobus sp. nov. and T. hagenia sp. nov., see descriptions of the latter species below.

Distribution

Known only from the northern slope of the Bale Mts, south of Goba city. The species was found at altitudes of approximately 2990 m to 3200 m (see also Magrini & Sciaky 2006).
