Trechus culminicola Jeannel, 1936

Trechus (s. str.) culminicola Jeannel, 1936: 207 ; locus typicus: Mt Chillalo, alt. approx. 4000 m.

Trechus culminicola – Ortuño & Novoa 2011: 137.

Type material

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

Material examined

ETHIOPIA: 1 ³, 1 ♀, Oromia, Mt Chillalo, alt. 3500–3800 m, Dec. 2006, 07°54′ N, 39°13′ E ( CAF, CSCHM).

Identification

The smallest Trechus species known to occur at Mt Chillalo (body length 3.0– 3.5 mm). Within the Trechus fauna of this volcanic massif, T. culminicola is most similar to T. gallorites ; for identification see key to species. Trechus culminicola can be easily distinguished from all species known from the Bale Mts and Mt Enkuolo with body size smaller than 3.5 mm based on the following combination of characters: two protarsomeres of male dilated; elytra moderately convex, slightly flattened on disc; micro-meshes on elytra rather large, more deeply engraved, almost isodiametric.

Distribution

Probably endemic to Mt Chillalo. The species has been found at altitudes of 3500–4000 m.
