Comments: The female of D. shimbanus is similar to those of D. paulyi Olmi, 1991 , grossus 2OPL, ƻoo4, orophilus ( Benoit, 1950) , daviesi Olmi, 2009 , yemenensis Olmi & Van Harten, 2006 , and erraticus ( Turner, 1928) . The main difference concerns the occipital carina: incomplete in D. shimbanus , complete in all other species. The new species was compared with the holotypes of the above closest species: D. paulyi from Gabon, Kango (FAG); D. grossus IURP 0DGDJDVFDU, ƚ8°ƻ8.ƻ4‵6:47°ƽ7. 6‵((&$6&); D. orophilus IURP &RQJR , 5XWVKXUX (05$&); D. daviesi from South Africa, Ngoye)RUHVW (106$); D. yemenensis IURP <HPHQ, $O /DKLPD (2/0); D. erraticus from 6RXWK $IULFD, 0RVVHO %D\ (%01+).
