isotype: K e! [ K000069295 , K000069296 ] , RB [ RB00145735 ], US [ US 00516843] ).

Distribution and habitat: — Brazil ( Bahia , with a disjunct distribution in the serras of the Chapada Diamantina and the lowland rainforests). Campo rupestre, seldom in restinga coastal forest; 450–1300 m.

Taxonomic Notes: —An uncommon species, distinct in the oblanceolate leaves with cuneate base and often broadly recurved margins and capitula entirely connate. Similar to Paralychnophora harleyi ( Robinson 1997: 90) Hind (2000a: 370) , but the latter has elliptic to obovate leaves and 5–12-flowered capitula (vs. 2–3). Resembling also to P. patriciana Hind (2000a: 371) , which has 25-flowered capitula concrescent only at the base. Application of the name P. bicolor has been reviewed by Loeuille et al. (2012c). As pointed out for Lychnophora uniflora , the type material of this species indicates Minas Gerais, whereas all further known collections come from Bahia State. It is probable that the information in the type label is erroneous.
