AbstractThe first-instar (triungulin), second-instar, and third-instar larvae of the South American monotypic genus Epispasta Selander, 1960 are described and figured. The triungulin of E. abbreviata (Klug, 1825) is highly adapted for phoresy on bees and resembles the triungulins of several other phoretic genera in the subfamily Meloinae. The second- and third-instar larvae of Epispasta are unique in that they retain the campodeiform phenotype of the first instar. These instars in other meloid genera are scarabaeiform. A discussion is provided on the similarity of the triungulin of Epispasta to that of other phoretic meloines. We argue that this similarity is a result of morphological convergence correlated with phoretic behavior and is not evidence of a relationship. The position of Epispasta in Meloinae remains questionable, as none of its larval or adult features ally it to any other genus.

The South American monotypic genus Notobothrus Parent (Diptera: Dolichopodidae), previously known only from its type locality in lowland Amazonian Peru, is newly recorded from the northwestern Brazilian Acre State. The single included species, N. longilamellatus Parent, is redescribed in detail, including the associated female for the first time. The genus is excluded from the subfamily Peloropeodinae and provisionally left incertae sedis within the Dolichopodidae. Key words: Taxonomy, Neotropical, Brazil, Neurigoninae, Peloropeodinae

AbstractA new monotypic genus, Bolbothyreus, is proposed for the South American species Stenaspidius ruficollis (Bruch). The new genus seems most closely related to Bolbapium Boucomont from South America and less so to Stenaspidius Westwood from Australia.

Nomina Dubia

A review of the original descriptions and available types of the South American freshwater stingrays Trygon aiereba Müller & Henle, 1841, Trygon strogylopterus Schomburgk, 1843 and Disceus thayeri Garman, 1913 indicates that these three nominal species are synonymous. The senior name, placed in the monotypic genus Paratrygon Duméril, 1865, established for Trygon aiereba, is available and valid. Based on its description, T. aiereba is a freshwater stingray. Therefore, this taxon is not the same as Raja ajereba Walbaum and Raja orbicularis Schneider, both names established for the marine "Aiereba" of Marcgrave, and which preferably should be treated as nomina dubia. Paratrygon does not replace Potamotrygon Garman, 1877 as the type genus, because the family name Potamotrygonidae Garman, 1877 has priority over Paratrygonidade Gill, 1893.

Six new species of Paracloeodes are described: four from Brazil (P. assu, P. atroari, P. peri and P. waimiri), one from Argentina (P. yuto) and one from Bolivia (P. pacawara), based on nymphs. Three other species from South America: P. binodulus, P. eurybranchus and P. ibicui are revised. A cladistic analysis including most of the South American species of Paracloeodes and the monotypic genus Iguaira is presented. A key for all South American species is included.

Molecular Characters

Generic boundaries of the South American species Panicum longipedicellatum Swallen are explored and compared with allied genera of the tribe Paniceae. On the basis of morphological, anatomical, and molecular characters a new genus, Cnidochloa Zuloaga, is proposed. The phylogenetic position of the new genus within the Paniceae is evaluated.
