Growth-pattern variation in two species of Rheumatobates (Heteroptera: Gerridae) with different degrees of sexual dimorphism

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 le...
