( Figs 12–14 )

Description: Length of body 11.5 mm, from anterior margin of head to posterior margin of elytra: 6 mm. Body black; antennae and legs brown. Head sub-rectangular, narrowed anteriad, with moderately rounded sides and narrowly rounded posterior angles. Eyes small and almost flat. Surface of head with deep, very dense punctation, apart a narrow median stripe. Some setiferous punctures near the eyes and the posterior angles. Pronotum dilated anteriad, as long as head, slightly narrower than it, with oblique anterior margins, rounded anterior angles and sinuate sides. Surface shiny, with dorsal series of 10-11 very irregular punctures and lateral, oblique series of 8-9 punctures; other punctures near the anterior angles. Elytra dilated posteriad, longer and wider than pronotum, with sub-rectilinear sides and rounded humeral angles. Surface with numerous, very fine, dense punctures, arranged in numerous series. Abdomen partially wrinkled, with evident punctation, arranged in numerous series on each segment.

Tergite and sternite of the male genital segment as in Figs 12-13 . Aedeagus ( Fig. 14 ) 2.6 mm long, large, subrectangular, with characteristic distal portion; parameres short, broad, provided with evident setae; inner sac tapelike, long and narrow, folded on itself one time, covered with very fine, longitudinal spinulae.

Etymology: The specific epithet refers to Ethiopia.

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

Remarks: The genus Gyrohypnus LEACH, 1819 is represented in Africa south of Sahara by 8 species, especially in the central regions ( Congo, Uganda, Kenya), apart from the aforementioned G. rougemonti , probably endemic to Ethiopia ( BORDONI, 2016).
