Hist., ser. 7, 10:314 . TYPE LOCALITY: Kenya , west slope of Mt. Kenya , 3000 m . DISTRIBUTION: Irregular highland distribution in W Kenya , Uganda , Rwanda , Burundi , and bordering Zaire ; outlying populations on Mount Cameroon . SYNONYMS: burtoni , dollmani , elgonis, faradjius, ghigii, nubilus, ruberculus, vivax , vulcanicus. COMMENTS: Regarded as conspecific with O. irroratus by Bohmann (1952) and accordingly recognized in regional treatments ( Delany, 1975 ; Kingdon, 1974); however, others have maintained the southern African form irroratus as specifically distinct from eastern African tropicalis ( De Graaff, 1981 ; Meester et al., 1986 ; Misonne, 1974 ). Even so, the taxa herein assembled under tropicalis (after Misonne, 1974 ) remain a composite of two or more species, whose definition and range will require careful revisionary work, involving simultaneous attention to possible relationships with species-group taxa now lumped under O. typus (see next account).
