( Figs 4B View Fig , 7B View Fig )

Type material. HOLOTYPE: J, KENYA: COAST: Kasigau Mtn., 3.82080°S 38.64178°E, 737 m, bottom of forest, woodland with grass, Malaise trap, 7–21.ix.2011, R. Copeland leg. ( NMKE). GoogleMaps

Diagnosis. Male with scutum strongly reticulate rugose; notauli incomplete, reaching approximately 0.5 length of scutum; posterior surface dull, with two complete longitudinal keels, median area crossed by numerous transverse keels and lateral areas rugose.

Description. Male. Fully winged; length 2.5 mm. Head black, except mandible testaceous; antenna brown, except segments 1–2 and ventral side of 3–5 testaceous; mesosoma and metasoma black; legs brown, except articulations, tarsi and protibiae testaceous.Antenna filiform; antennal segments in following proportions: 11: 7: 9: 9: 8: 8: 8: 8: 7: 9; antennal segment 8 less than three times as long as broad (8:3). Head convex, dull, covered with short hairs, completely strongly reticulate rugose; frontal line complete, weakly convex between antennal toruli; occipital carina complete; POL = 7; OL = 3; OOL = 9; OPL = 4; TL = 6; greatest breadth of posterior ocelli about as long as OL. Scutum dull, completely strongly reticulate rugose. Notauli incomplete, reaching approximately 0.5 length of scutum. Scutellum dull, with anterior half granulated and posterior half rugose. Metanotum rugose. Mesopleuron dull, strongly reticulate rugose. Metapleuron dull, sculptured by numerous strong transverse keels. Propodeum with strong transverse keel between dorsal and posterior surface; dorsal surface dull, reticulate rugose; posterior surface dull, with two complete longitudinal keels, median area crossed by numerous transverse keels and lateral areas rugose. Forewing hyaline, without dark transverse bands; distal part of stigmal vein shorter than proximal part (8: 15); marginal cell open. Genitalia in Fig. 4B View Fig . Tibial spurs 1/1/2.

Female. Unknown.

Differential diagnosis. Based on the characters summarized in the above diagnosis, in the Afrotropical Region the new species is similar to Bocchus fynbosensis Olmi, 2006 and B. incompletus Olmi, 2005a . The main difference among these species regards the sculpture of the scutum: strongly reticulate rugose in B. johanssoni ; completely granulated or granulated and sculptured by weak or strong irregular keels or areolae in B. fynbosensis and B. incompletus . In addition, the median area of the posterior surface of the propodeum is crossed by transverse keels in B. johanssoni , reticulate rugose in the other two species.

Etymology. This species is named after Tino Johansson, director of the CHIESA project, funded by the people of Finland, that is examining the effects of climate change on agro-ecosystems in the Taita Hills, Kenya, of which Kasigau Mountain is an outlier.

Hosts. Unknown.

Distribution. Only known from the type locality.
