A New Species

AbstractMichaelshaffera gen. n. is comprised of two species, M. maidoa (Schaus), new combination, the type species, described from French Guiana, and a new species, M. beckeri, here described from South America. The assignment of taxa to the Pyraloidea is based primarily on characters of the tympanal organs and immature stages. Michaelshaffera lacks a tympanal organ and the immatures are unknown. The rationale for the placement of this genus in the Pyraloidea and lower hierarchical ranks is discussed based on other morphological characters.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

A New Species

Paspalum chilense, a new species from Chile belonging to the informal Notata group, is described and illustrated on the basis of morphological, cytological and molecular evidence. Our evidence supports its affinity with P. barretoi and P. nummularium, from Brazil, from which it probably diverged by vicariant speciation. The limited available material of the new species was previously identified as P. pumilum or P. minus. A new key to the species of the core Notata group is provided.
