摘要:

The taxonomy of the Neotropical genusSampsoniusEggers is reviewed. Fourteen species (2 new) are included in the genus. The genus is redescribed, a key to all species is included and each species is redescribed. All available data on distribution is included. New species are:alvarengai(Brazil) andmexicanus(Mexico). Illustrations of most species are included.

摘要:

Three cases of hybridization obtained in laboratory conditions betweenCentruroides gracilisandCentruroides margaritatusbring some evidence on the genetic relationship between these two species. The experiments were done with specimens collected in Florida (USA), Mexico and Colombia.

摘要:

Neosanfilippia zoiai, new species of terrestrial Isopod from Ecuador is described. The diagnostic characters between the new species and the only current species of the genus,Neosanfilippia venezuelanaBrian, 1957, are discussed. The relationships between the genusNeosanfilippiaand the genusAmazoniscusLemos de Castro, 1967, are discussed. For scanning electron miscroscopy, specimens were fixed in 70% ethanol, dried by air, coated with gold, and studied in a Cambridge Stereoscan 200.

摘要:

Leptodactylus latinasusJiménez de la Espada, 1875 at Punta Lara, Province of Buenos Aires, Argentina, was assigned to cohorts on the basis of snout‐vent length, development, and reproductive condition. Frogs were sampled by pitfall traps during December 1985 to November 1986. Two age‐classes were observed during this period. Bertalanffy's model was applied for the study of growth, which showed an effective fitness to the data obtained from the samples.

摘要:

The tadpoles ofHyla armata(Hylidae)and Bufo veraguensis(Bufonidae) from the Amazonian slopes of the Andes in southern Peru and Bolivia are described. These tadpoles, collected from streams draining the Cordillera Oriental in southern Peru, have modifications reflecting adaptations to stream life. These include, inHyla armata, an enlarged oral disc with numerous labial tooth rows and complete marginal papillae and, inBufo veraguensis, a belly sucker, unique within the genus but similar to the more fully‐developed sucker ofAtelopustadpoles. In addition,Bufo veraguensistadpoles are unusual forBufoin having a dextral vent, high density of labial teeth with no unbroken rows, and small external nares. The morphology of the tadpoles ofHyla armataandBufo veraguensisis as yet uninformative regarding the relationships to these two unusual frogs. The advertisement call ofHyla armataconsists of a single, high‐pitched note with a dominant frequency of 4.7 KHz.
