Trechus patrizii Jeannel, 1960

Trechus (s. str.) patrizii Jeannel, 1960: 265 ; locus typicus: “mont Chillálo”.

Trechus patrizii – Ortuño & Novoa 2011: 135.

Type material

Not studied. Identification of this distinctive species is based on its detailed description including figures of habitus and genital characters.

Type locality

The description is based on two specimens collected on Mt Chillalo by S. Patrizii on April, 27 th, 1936, one from “Torre Asciaba, alt. 2500 m env.”, the other from “pays Aselle, alt. 2600 m env.” ( Jeannel 1960: 266). However, Jeannel (1960) gave no information about the details of the label data of the holotype specimen.

Identification

Within the Trechus fauna of the Oromia region this species is unique due to the absence of the laterobasal setae of pronotum. Additional diagnostic features are: medium body length (approx. 3.6 mm), two protarsomeres of male dilated, each elytron with a single seta on disc (posterior discal seta lacking).

Distribution

Known only from two localities at the western slope of Mt Chillalo at altitudes of 2500 m and 2600 m ( Jeannel 1960).
