“…2). Since Hennings original description of C. locustiphila, most of the records have originated from western Amazon (Hennings 1904, Petch 1933, Evans 1982, the center of the distribution of Romaleidae (Amegdanato and Descamps 1982).…”

“…It is hypothesized that its high endemism could be the product of ancient age and proximity to the Andean foothills (Morrone 2000). Region 2, located in Western Amazon, which is defined as west of the Madeira River in Brazil, east of the Andes and south of the Guyana Shield, is an area significantly influenced by the Amazon floodplain (Amedegnato and Descamps 1982). Finally, region 3 is the Guyana Shield, which dates to the Cretaceous and is considered the most ancient terrestrial landscape of South America (Morrone 2000).…”

In the Amazon the only described species of Cordyceps sensu stricto (Hypocreales, Cordycipitaceae) that parasitize insects of Orthopterida (orders Orthoptera and Phasmida) are Cordyceps locustiphila and C. uleana. However, the type specimens for both taxa have been lost and the concepts of these species are uncertain. To achieve a more comprehensive understanding of the systematics of these species, collections of Cordyceps from the Amazon regions of Colombia, Ecuador and Guyana were subjected to morphological, ecological and molecular phylogenetic studies. Phylogenetic analyses were conducted on partial sequences of SSU, LSU, TEF, RPB1 and RPB2 nuclear loci. Two new species are proposed including C. diapheromeriphila, a parasite of Phasmida, and C. acridophila, a parasite of the superfamily Acridomorpha (Orthoptera), which is broadly distributed across the Amazon. For C. locustiphila a lectotypification and an epitypification are made. Cordyceps locustiphila is host specific with Colpolopha (Acridomorpha: Romaleidae), and its distribution coincides with that of its host. The phylogenetic placement of these three species was resolved with strong support in the Beauveria clade of Cordyceps s. str. (Cordycipitaceae). This relationship and the morphological similarity of their yellow stromata with known teleomorphs of the clade, suggest that the holomorphs of these species may include Beauveria or Beauveria-like anamorphs. The varying host specificity of the beauverioid Cordyceps species suggest the potential importance of identifying the natural host taxon before future consideration of strains for use in biological control of pest locusts.

Most members of the superfamily Acridoidea (Orthoptera) oviposit in the soil, but some species oviposit directly on or in tissue of host plants. Oviposition in association with host plants has been reported for only 6% of acridoid species for which oviposition behaviour is known, h u t the behaviour is systematically and geographically widespread, including members of two families and seven acridid subfamilies on three continents. 'This distribution suggests that host plant oviposition by grasshoppers has evolved independently at least eleven times in the world's grasshopprr fauna. A comparative approach to investigating oviposition on host plants shows that it tends to occur in species ofinundated habitats and tropical forests, in species with narrow diets, and is correlated with a reduction in clutch size.
