The psyllid genus Ciriacremum (Hemiptera, Psyllidae) in Brazil
Ciriacremum is a genus of Ciriacreminae (Hemiptera, Sternorrhyncha, Psylloidea, Psyllidae) comprising 26 validly described species in the Afrotropical realm and only one in the Neotropics. Here we add four new species from Brazil, which are named and diagnosed, including illustrations and an identification key for adults: Ciriacremum lanceolatum sp. nov. (from Mato Grosso), C. maederae sp. nov. (from Amazonas), C. pollicigerum sp. nov. (from Amazonas) and C. roraima sp. nov. (from Roraima). Two other species are reported from Brazil (Amazonas and Pará) but not formally named due to insufficient material. Apart from C. setosum (from Nicaragua) and the Brazilian species treated in this paper, there are at least four additional undescribed species from the Neotropics (Colombia, Guyana, Panama, Suriname, and Venezuela), which are briefly discussed. Little is known about the immatures and host plants of the Neotropical species. The only confirmed host is Hymenaea sp. (Fabaceae) of C. maederae sp. nov. Adults were collected also on other fabaceous genera that are possible hosts. In the Neotropics, Ciriacremum is restricted to the tropics between Nicaragua in the north and Brazil (Mato Grosso) in the south.
