Examined material: Holotype: Ethiopia, Oromia prov., Mt Enkuolo , NE slope, 3100-3200 m, 07°24'41"N,

39°22'26"E, J. Schmidt 5-7.XII.2016 ( NME) .

Description: Length of body 10 mm, from anterior margin of head to posterior margin of elytra: 5.4 mm. Head and pronotum black, elytra black with more than back half red, abdomen reddish brown with reddish paratergites; antennae and legs brown black. Similar to G. aethiopicus sp. n. but smaller, narrower, with different color; head very similar but with less dense punctation, absent on a median stripe and very superficial at the inner side of the eyes; lateral portion of head without punctation, shiny; eyes smaller; pronotum narrower, less dilated anteriad, with more rounded anterior angles and finer punctation; dorsal series of 3-4 anterior punctures and 5-6 posterior punctures; elytra shorter and narrower, less dilated posteriad, with more marked humeral angles; abdomen shiny.

Sixth visible abdominal tergite with a median, rectangular protrusion.

Male unknown.

Etymology: The specific epithet refers to Oromia province.

Distribution: The species is known only from the type locality.

Remarks: In Ethiopia occurs two species of this genus, G. remotu s, also known from Kenya and Congo ( BORDONI, 2016) and G. rougemonti , endemic taxon (Arussi prov.). To this last species G. oromianus spec. nov. differs by the following characters: longer and narrower body, different color; head anteriad more narrow, with sparser punctation; eyes smaller and in a more lateral position; more protruding epistoma; narrower pronotum, with different punctation; smaller elytra.

G. remotus is a very smaller species (7 mm long), brown black with reddish pronotum, visible abdominal segments 5 th and 6 th and genital segment; different punctation on pronotum and elytra. The new species in fact is immediately distinguished from congeners for coloring.
