Clinical Syndromes

Isozyme analysis (12 enzymes: 14 loci) was conducted on 99 isolates of Trypanosoma cruzi: 77 from Guatemala, 5 from Mexico and 17 from South American countries. Analyses of 4 population-genetic indices were undertaken to assess the possibility of genetic exchange occurring among Guatemalan isolates. The results provide evidence for a degree of genetic exchange occurring among isolates from this relatively small geographical area. Previous studies of population genetics on T. cruzi might have failed to detect this phenomenon because they tended to use isolates originating far from one another, rendering gene exchange unlikely for geographical reasons. Phylogenetic data, presented here, show considerable differences in genetic structure between Central and South American isolates, suggesting that different biological and clinical properties might be expected. For example, there are differences in clinical syndromes between Central and South America, a situation discussed further here.

Geological Formation

A new genus, Tikuna, is described based on recent collections of adults and nymphs of Choroterpes atramentum Traver from western Costa Rica. All recent collections are from streams on or near the Nicoya Complex, the oldest geological formation in Lower Central America. Tikuna belongs to a lineage of South American Atalophlebiinae (Leptophlebiidae: Ephemeroptera) whose origin is hypothesized to have been in the late Cretaceous–early Tertiary. Some implications of the distribution of Tikuna for theories on the origin of Costa Rica’s biota are discussed.

New Diagnosis

Hoplonannus McAtee & Maloch, 1925 comprises three species described from Central America. Females of all these species are known only from brachypterous specimens. This paper describes the first South American species of the genus, Hoplonannus australis sp. nov. The new species differs from its congeners, in females, by the submacroptery, presence of ocelli and a basal bulge in the seventh sternite; in males, it differs by the presence of a process in the eighth tergite and the right paramere bifurcate apically, with branches subparallel. These traits entail a new diagnosis for the genus.

Taxonomic Order

New and unusual host records for 133 species and subspecies of Pompilidae predominantly from the southwestern United States, Mexico, Central America, and South America are presented in modified taxonomic order. First-time species host records are given for Calopompilus Ashmead, Pepsis Fabricius, Hemipepsis Dahlbom, Priocnessus Banks, Entypus Dahlbom, Pompilocalus Roig-Alsina, Sphictostethus Kohl, Auplopus Spinola, Ageniella Banks, Eragenia Banks, Aporus Spinola, Poecilopompilus Ashmead, Tachypompilus Ashmead, Anoplius Dufour, Priochilus (Fabricius) and Notocyphus Smith. New host spider families are introduced for Calopompilus, Pepsis, Hemipepsis, Priocnessus, Entypus, Cryptocheilus Panzer, Priocnemis Schiødte, Auplopus, Ageniella, Eragenia, Aporus, Tachypompilus, Anoplius, Priochilus and Notocyphus. Eight host spider families are reported from the Western Hemisphere for the first time: Halonoproctidae (Notocyphus dorsalis dorsalis Cresson); Dipluridae (Pepsis pretiosa Dahlbom, P. montezuma Smith, P. infuscate Spinola, P. atripennis Fabricius, P. martini Vardy, Priocnessus vancei Waichert and Pitts); Nemesiidae (Pepsis pallidolimbata Lucas, P. viridis Lepeletier, P. spp., Pompilocalus hirticeps (Guérin), Sphictostethus gravesii (Haliday), S. striatulus Roig-Alsina, Priocnemis oregona Banks); Barychelidae (Eragenia sp.); Paratropididae (Pepsis stella Montet); Trechaleidae (Hemipepsis toussainti (Banks), Entypus unifasciatus cressoni (Banks), Tachypompilus ferrugineus (Say), Tachypompilus unicolor cerinus Evans, Priochilus gloriosum (Cresson); Desidae (Ageniella accepta (Cresson), Sphictostethus isodontus Roig-Alsina) and Selenopidae (Priochilus scrupulum (Fox), Tachypompilus erubescens (Taschenberg) or xanthopterus (Rohwer)). The first known host records for the rare South American pompilid genera Chirodamus (Lycosidae: Lycosa sp.) and Herbstellus (Nemesiidae: Diplothelopsis cf bonariensis Mello-Leitão) are presented.

Major Pest

Gnamptogenys triangularis(Mayr), native to the forests of South and Central America, is a predatory ant that feeds on millipedes. In its native range, this species is known from Buenos Aires, Argentina (38.1°S) in the south to Costa Rica (10.4°N) in the north, with records from eight countries in South America (all except Chile, French Guiana, and Paraguay), and the two southernmost countries of Central America (Panama and Costa Rica). The first records ofG. triangularisoutside its native range came from Florida beginning in 1985 (six sites: 25.5°–30.4°N) and Alabama in 1996 (one site: 30.4°N). Here we present the first records ofG. triangularisfrom Mississippi, dating from 2002–2010 (five sites: 30.5°–31.2°N). Based on its South American range, it appears thatG. triangularishas the potential to spread to forests throughout much of the southeastern USA. There are no documented impacts ofG. triangularis,and it seems unlikely that this species will ever become a major pest.
