Última Adaptations of two specialist herbivores to movement on the hairy leaf surface of their host, Solanum guaraniticum Hassl (Solanaceae) Rev. Bras. entomol. Medeiros,Lenice; Boligon,Danessa S.. Plant trichomes can difficult the attachment and movement of small insects. Here, we examine the hypothesis that the success on the use of densely haired hosts by two cassidine species is determined by differential morphology and behavior. Larvae of Gratiana graminea (Klug, 1829) and Gratiana conformis (Boheman, 1854) move on the leaf surface of their host, Solanum guaraniticum Hassl by anchoring their tarsungulus on the trichome rays or by inserting the tarsungulus tip directly into epidermis. This kind of movement is only possible due to a similar tarsungulus shape among the species. Tarsungulus growth pattern is also similar between species, being relatively small on the posterior aperture, matching the diameter of the host plant trichome rays. The...

Gratiana boliviana Spaeth, 1926 is redescribed, compared with G. conformis (Boheman, 1854), G. graminea (Klug, 1829), G. insculpta (Boheman, 1855), G. inurbana Weise, 1921, G. lutescens (Boheman, 1854), G. pallidula (Boheman, 1854) and G. spadicea (Klug, 1829). The host plant of G. boliviana is Solanum viarum Dun (Solanaceae). Tipo: Info:eu-repo/semantics/article Palavras-chave: Coleoptera; Chrysomelidae; Cassidinae; Gratiana; Neotropical. Ano: 1995 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0101-81751995000200012 Morphometrical aspects of adults of Gratiana spadicea (Klug) Coleoptera, Chrysomelidae) from Southern Uruguay BJB PONCE DE LEÓN,R.; FAILLA,G.; MORELLI,E.. Morphometrical data of pronotum, elytra, and total length of adult males and females of a Gratiana spadicea population from southern Uruguay are given. Descriptions and illustrations of aedeagus and spermatheca are provided for the first time. Females were significatively larger than males in total length. The coefficient of variation of the aedeagus measures ranged from 3.7% to 7.7%, and those of the spermatheca from 4.1% to 11.2%. The best value for the coefficient of determination was obtained for the reciprocal regression (1/Y = a + bX) of the total length of the aedeagus versus the length from the apex to the basal region of the median lobe.
