| Two additional species of Lessingianthus (Vernonieae, Asteraceae) from the Brazilian highlands are described and illustrated. One of the new species, Lessingianthus barrosoanus, is characterized by the presence of solitary heads disposed in relatively long, flexuous branches. It has certain resemblance to L. ligulifolius (Mart. ex DC.) H. Rob., which has short, commonly erect branches of the inflorescence, and capitula geminate or disposed in groups. Lessingianthus minimus is closely related to L. reitzianus (Cabrera) H. Rob., but differs in having acuminate phyllaries, glabrous corolla lobes and lanceolate leaves, cuneate at the base. |

| ABSTRACT In the state of Rio Grande do Sul, there are few records of geographical distribution and host plants to species of Tomoplagia Coquillett, as well as other genera of Tephritidae, especially those associated with plants of the family Asteraceae. Here, we report the first occurrence of Tomoplagia rudolphi (Lutz & Lima, 1918) in the state of Rio Grande do Sul, inducing stem galls in Vernonanthura tweediana (Baker) H. Rob. (Asteraceae, Vernonieae), whose plant becomes a new host record for this species. In this way, is increased to nine species of Tomoplagia recorded for Rio Grande do Sul. Biological and morphological data and photos of gall, larvae, pupae at new host and distribution map of the species in Brazil are provided. |

| O presente estudo abrange o gênero Piptocarpha R.Br. (Vernonieae: Asteraceae) no Estado do Paraná, Brasil. A metodologia consistiu no levantamento bibliográfico, coleta de material e observação de campo, estudos morfológicos e taxonômicos do material vivo e herborizado. Foram confirmadas para o Estado do Paraná nove espécies, sendo quatro escandentes: Piptocarpha leprosa (Less.) Baker, P. oblonga (Gardner) Baker, P. quadrangularis (Vell.) Baker e P. sellowii (Sch.Bip.) Baker; e cinco arbóreas: Piptocarpha angustifolia Dusén ex Malme, P. axillaris (Less.) Baker, P. densifolia Dusén ex G.L. Smith, P. macropoda (DC.) Baker e P. regnellii (Sch.Bip.) Cabrera. São apresentadas chave de identificação, descrições morfológicas, época de floração e frutificação,... |
