Appendix 2. A listing of the Pseudacteon associated with
Solenopsis saevissima fire ants with the countries and
secondary order administrative areas where each has been identifed, as well as
host information. Host data provided is based only on field associations since
the majority of species have not been reared.
| Pseudacteon associated with the Solenopsis saevissima complex. |
|---|
| Pseudacteon affinis is a Brazilian endemic found in the states of Goiás, Mato Grosso, Rio de Janeiro and São Paulo. Host: S. saevissima. (Map 2) |
| Pseudacteon borgmeieri has been found in Argentina (Buenos Aires, Chaco, Corrientes, Entre Ríos, and Santiago del Estero) and Brazil (Goiás, Paraná, Rio de Janeiro, São Paulo and Santa Catarina). Hosts: S. interrupta, S. invicta, S.macdonaghi, S. richteri, S. saevissima. (Map 3). |
| Pseudacteon bulbosus is found only in the province of Santiago del Estero in western Argentina. Hosts: S. interrupta, S. nr. electra. (Map 4). |
| Pseudacteon calderensis is known from Jujuy and Salta in Argentina. Along with P. bulbosus, it is one of two species endemic to the northwestern part of Argentina. Host: Solenopsis interrupta. (Map 4) |
| Pseudacteon comatus is found in Argentina (Buenos Aires, Chaco, Santa Fé, Santiago del Estero provinces) and Brazil (Paraná and Rio de Janeiro states). Hosts: S. interrupta, S. invicta, S. richteri, S. saevissima. (Map 5). |
| Pseudacteon conicornis is another Brazilian native narrowly limited to the Atlantic coast in the states of Espiritu Santo, Rio de Janeiro, Santa Catarina and São Paulo. Host: S. saevissima. (Map 6). |
| Pseudacteon cultellatus is found in Argentina (Buenos Aires, Chaco, Corrientes, Santa Fé and Santiago del Estero) and Brazil (Goiás, Mato Grosso, Paraná and São Paulo). Hosts: S. interrupta, S. invicta, S. macdonaghi, S. richteri, S. saevissima. (Map 7). |
| Pseudacteon curvatus is widely distributed in Argentina (Buenos Aires, Catamarca, Chaco, Córdoba, Corrientes, Entre Ríos, Formosa, Jujuy, Misiones, Río Negro, Salta, Santa Fé, Santiago del Estero and Tucumán), Bolivia (Tarija), Brazil (Mato Grosso, Mato Grosso Sur, Paraná, São Paulo, Santa Catarina) and Paraguay (Concepción, San Pedro). Hosts: S. interrupta, S. invicta, S. macdonaghi, S. quinquecuspis, S. richteri, S. saevissima. (Map 8). |
| Pseudacteon dentiger is found broadly over Brazil and has the second widest geographical range of species associated with the Solenopsis saevissima complex. It has been found in the states of Amazonas, Bahia, Goiás, Mato Grosso Sur, Paraná, Pernambuco and São Paulo. Hosts: S. invicta, S. saevissima. (Map 9). |
| Pseudacteon disneyi is found in Brazil (Goiás, Mato Grosso Sur and São Paulo) and was recently collected in northwest Argentina (Jujuy, Salta, Tucumán) and Bolivia (Tarija). The collected material from Argentina are somewhat intermediate between P. pradei and P. disneyi. This paper is not the place to resolve this taxonomic issue, but it is possible that with more collecting, these species will eventually be lumped, remain the same, or be split into two or more species. Hosts: S. invicta, S. saevissima. (Map 10). |
| Pseudacteon fowleri is known from Brazil (Goiás, São Paulo) and Guyana. Host: S. saevissima. (Map 11) |
| Pseudacteon lenkoi is another Brazilian endemic known from Goiás and São Paulo. Hosts: S. invicta, S. saevissima. (Map 12). |
| Pseudacteon litoralis is a wide ranging species known from Argentina (Buenos Aires, Chaco, Corrientes, Entre Ríos, Formosa, Jujuy, Misiones, Río Negro, Salta, Santa Fé, Santiago del Estero), Bolivia (Tarija), Brazil (Mato Grosso, Mato Grosso do Sur, Paraná, São Paulo) and Paraguay (Itapúa). Hosts: S. interrupta, S. invicta, S. quinquecuspis, S. richteri, S. saevissima. (Map 13). |
| Pseudacteon nocens is found in Argentina (Buenos Aires, Chaco, Córdoba, Corrientes, Entre Ríos, Formosa, Neuquén, Salta, Santa Fé, Río Negro and Santiago del Estero) Brazil (Mato Grosso do Sur) and Paraguay (Caaguazú). Hosts: S. interrupta, S. invicta, S. macdonaghi, S. quinquecuspis, S. richteri, S. saevissima. (Map 14). |
| Pseudacteon nudicornis is widely distributed in Argentina (Buenos Aires, Catamarca, Chaco, Corrientes, Formosa, Jujuy, Santa Fé, Santiago del Estero and Tucumán), Bolivia (Tarija) and Brazil (Mato Grosso, Mato Grosso do Sur, Paraná, Santa Catarina and São Paulo). Hosts: S. interrupta, S. invicta, S. richteri, S. saevissima. (Map 15). |
| Pseudacteon obtusus has the greatest geographical range by all estimates for any of the Pseudacteon associated with the S. saevissima complex. Its recognized distribution contains populations that extend to the all directional limits, including the northern and southern limits, of the S. saevissima complex. It is the only Pseudacteon known from Chile (Concepción). Broadly dispersed in Argentina (Buenos Aires, Chaco, Corrientes, Entre Ríos, Formosa, La Pampa, Mendoza, Río Negro, Salta, Santa Fé, Santiago del Estero and Tucumán), it is also known from Brazil (Mato Grosso, Para, Paraná, Santa Catarina) and Paraguay (Alto Paraná and Itapúa). Hosts: S. gayi, S. interrupta, S. invicta, S. quinquecuspis, S. richteri, S. saevissima. (Map 16). |
| Pseudacteon nr. obtusus is an undescribed species that was recently determined to be genetically different from the nominal P. obtusus. This taxon has been recognized in Argentina (Buenos Aires, Chaco, Corrientes, Entre Ríos, Formosa, Santa Fé and Santiago del Estero), Brazil (São Paulo) and Paraguay (Itapúa). Hosts: S. interrupta, S. invicta, S. saevissima. (Map 17). |
| Pseudacteon pradei is distributed primarily in the eastern Brazilian states of Minas Gerais, Rio de Janeiro, Santa Catarina and São Paulo but has been found in the more western states Mato Grosso do Sul and Mato Grosso. One specimen was labeled from the Canal Zone in Panamá. Hosts: S. invicta, S. saevissima. (Map 18) |
| Pseudacteon solenopsidis is unusual it that it has a radically different attack behaviour than all other Pseudacteon, particularily its tendency to fly backwards while facing a potential host ant (Orr et al. 1997). It is found in Argentina (Corrientes, Entre Ríos, Formosa, Misiones, Santa Fé and Santiago del Estero) and Brazil (Goiás, Mato Grosso Sur, Rio de Janeiro, Rio Grande do Sul and São Paulo). Hosts: S. interrupta, S. invicta, S. megergates, S. saevissima. (Map 19). |
| Pseudacteon tricuspis is one of the most common species in sites all across its range in South America. It is found in Argentina (Buenos Aires, Catamarca, Chaco, Corrientes, Entre Ríos, Formosa, Jujuy, Mendoza, Misiones, Neuquén, Río Negro, Salta, Santa Fé, Santiago del Estero), Bolivia (Tarija), Brazil (Goiás, Mato Grosso, Mato Grosso do Sur, Paraná, Rio de Janeiro, São Paulo) and Paraguay (Alto Paraná, Concepción, Itapúa). Hosts: S. interrupta, S. invicta, S. quinquecuspis, S. richteri, S. saevissima. (Map 20). |
| Pseudacteon wasmanni is a Brazilian endemic primarily found along the southern Atlantic coast, though its range extends into the interior of the country (Espiritu Santo, Mato Grosso, Minas Gerais, Rio de Janeiro, Santa Catarina and São Paulo). Hosts: S. invicta, S. saevissima. (Map 21). |
