Abstract:

Growth patterns of Rheumatobates crassifemur crassifemur Esaki and R. bonariensis (Berg) were compared in a multivariate framework. Study of allometric coefficients in R. bonariensis showed sexual differences biased towards males in antennal and foreleg segments and biased towards females in body length and middle-leg segments. Multivariate allometric analysis of female growth patterns detected variation among species in those characters that are strongly modified in males of R. c. crassifemur. We show that sexual morphology diverges as of nymph V in R. c. crassifemur but only in the adults of R. bonariensis. © 2008 Entomological Society of Canada.
