| Abstract | |
This work has a detailed study of the morphology of Ceraeochrysa, distribution maps for the species of the genus, lists of occurrences in crops of the Brazilian species and a phylogenetic analysis of the relationships between the species of the genus. The phylogenetic study included 62 species of Ceraeochrysa, with four outgroup species and 50 morphological characters. A total of 11 species for which there is missing data for males were included in the matrix one by one and analysed independently, so negative effect of missing data in the analysis could be reduced. The monophyly of the genus was recovered, but no uniquely derived characters were found. Of the features often considered synapomorphies of Ceraeochrysathe presence of an elongated spermatheca and the presence of a gonapsisthe former of spermatheca is plesiomorphic for C. placita and C. intacta (which have pill-box format), recovered as sister species for the remaining of the genus, while a gonapsis was seen to also occur in Criptochrysa. The detailed morphological study resulted in a lot of information that can be used in robust phylogenetic studies of the Chrysopidae. Most of the Brazilian species of Ceraeochrysa are known from the Amazon, the Atlantic Forest and the Cerrado, but there is not information enough for a biogeographic study of the genus. Among the Brazilian species, C. cincta, C. cubana, and C. claveri are those that have most widely distributed and occur in great variety of agricultural crops. (AU) | |
