Affinities unclear; probably an old endemic species of Solomon Is. Hitherto treated as conspecific with Z. hamlini (which see). Sometimes listed as “Z. ugiensis”, as name rendovae has erroneously been applied to Rendova form of Z. kulambangrae, with much resultant confusion#R#R#R#R down to present. Species originally described by E. P. Ramsay in 1881 as Tephras olivaceus, from “Solomon Islands”; when transferred to present genus, name became preoccupied by Z. olivaceus of Reunion I (see that species). Consequently, it was explicitly given substitute name (rendovae) in 1882 by Tristram, who simultaneously adjoined a description of the Rendova form, thus effectively applying his name to two species at once; under ICZN Code (Article 72.7; see also 49), status as replacement name takes precedence, so olivaceus and rendovae are objective synonyms, with same type specimen (of San Cristobal form). Later in 1882, Ramsay himself renamed the species ugiensis, but name rendovae already had priority, thus ugiensis merely a third objective synonym. Emanating from ensuing confusion of names, forms and localities, ramsayi is fourth objective synonym and anyway preoccupied by a name currently included within synonymy of Z. lateralis vegetus (see Z. lateralis account); salomonensis is a fifth; alberti is a junior subjective synonym of rendovae. In past, name olivaceus also erroneously applied to birds of Rendova. Apparently on basis purely of name, form ugiensis [= rendovae] was wrongly claimed to occur on Ugi. Two subspecies recognized.
