El traslado del Congreso anfictiónico de Panamá al poblado de Tacubaya (1826-1828)

El artículo estudia el traslado del Congreso anfictiónico de Panamá a Tacubaya y los diversos intentos de instalación de la 'Asamblea americana' en México entre 1826 y 1828. Su propósito es escalonado: primero identifica los significados decisionales relevantes para comprender el fracaso del proyecto y, enseguida, delimita la autonomía analítica del episodio mexicano del Congreso de Bolívar.

The formative platform of the Congress of Panama (1810-1826): the Pan-American conjecture revisited

This article examines the formative platform of the Congress of Panama of 1826. It seeks to support the hypothesis that the nature and scope of the first test of integration in the Western Hemisphere depended critically on the platform created by Simón Bolívar and other Latin American Independence heroes from the Declaration of Independence of Venezuela in 1810 until the last bilateral agreement of 1826. In that respect, it corroborates the Latin American Identity of the initiative.

Quatro especies nuevas de nematodos del sur del Perú y redescripción de Hedruris Orestiae Moniez, 1889

En el estudio helmintológico de anfibios del género Telmatobius Wiegmann, 1834, y del pez Orestias luteus Valenciennes, 1839, de las zonas de Arequipa, Puno y del Lago Titicaca, se han encontrado nematodes de los géneros Hedruris Nitzsch, 1821 y Falcaustra Lane, 1915. Se redescribe Hedruris orestiae Moniez, 1889 y se describen cuatro especies nuevas: Hedruris moniezi sp. n., Falcaustra condorcanquii sp. n., Falcaustra pumacahuai sp. n. y Falcaustra tiahuanaquensis sp. n.

Estudo comparativo da genitália externa masculina de duas espécies de Zelurus Hahn, 1826 (Hemiptera, Reduviidae, Reduviianae)

Objetivando estabelecer novos parâmetros taxonômicos para o gênero Zelurus Hahn, 1826, foi feito um estudo detalhado e comparativo da genitália externa dos machos de duas espécies: Z. circumcinctus (Hahn, 1835) lepeletierianus (Kirdaldy, 1909). Foram evidenciadas como mais representativas as seguintes estruturas fálicas: processo do pigóforo, parâmetro, falosoma, suporte do falosoma e processo 2 do endosoma.

Description of the adult form of Nybelinia (Syngenes) rougetcampanae Dollfus, 1960 and some new data on n. (n.) bisculata (Linton, 1889) (Trypanorhyncha: Tentaculariidae)

The adult form of Nybelinia (Syngenes) rougetcampanae Dollfus, 1960 is described, parasitizing one specimen of Sphyrna lewni (Griffith & Smith, 1834) out of the five ones necropsied and one out of six Nothorhynchus pectorosus (Garman, 1884) was found harbouring N. (N.) bisculata (Linton, 1889). The finding of these cestodes under Trypanorhyncha in sharks captured off the coast of Rio Grande do Sul State, Brazil, amplifies their known geographical distribution and adds new host records for these parasites.

First report of Temnocephala brevicornis Monticelli 1889 (Temnocephalidae: Platyhelminthes) in Argentina

Temnocephala brevicornis Monticelli 1889, ectosymbiont of Hydromedusa tectifera Cope 1869, is reported for the first time for Argentina. Numerous temnocephalans from Arroyo Villoldo in the locality of Magdalena, Buenos Aires, Argentina were stained in toto to be studied. This commensal species in turtles was originally cited in association with Hydromedusa maximiliani (Mikan) and Hydraspis radiolata Mikan in Brazil. Afterwards, it was found on other fresh water turtle species in Brazil and Uruguay.
