Résumé
ABSTRACT The external morphology of immature stages of Zaretis strigosus (Gmelin, [1790]) and Siderone galanthis catarina Dottax and Pierre, 2009 comb. nov. from southern Brazil are described. Additionally, morphology of the adults and sequences of the mitochondrial gene cytochrome oxidase, subunit I, were analyzed in order to evaluate the taxonomy of Siderone galanthis Hübner, [1823]. Immatures were collected on Casearia sylvestris (Salicaceae) in Curitiba, Paraná, and Balneário Barra do Sul, Santa Catarina, Brazil, and reared at the laboratory. Morphological descriptions and illustrations are provided, based on observations through stereoscopic and optic microscopes attached to camera lucida; results are compared and discussed and immature stages of some other species of Charaxinae. The results indicates that the morphology of the immature stages of the studied species differ greatly from other Anaeini, representing a distinct lineage of leafwings butterflies. Morphology and molecular evidence indicate that S. nemesis mexicana Dottax and Pierre, 2009 and S. nemesis catarina Dottax and Pierre, 2009 are conspecific with S. galanthis (Cramer, 1775); additionally, S. thebais C. Felder and R. Felder 1862, S. nemesis var. confluens Staudinger, 1887, S. nemesis f. leonora Bargmann, 1928 and S. nemesis f. exacta Bargmann, 1929 are synonymized with S. galanthis galanthis (Cramer, 1775).
Résumé
Immature stages of Memphis moruus stheno (Prittwittz) were subject of a behavior, biological and morphological study. The morphological study was carried out through observation by stereoscopic microscopy with camera lucida and micrometric lens attached for illustrations and measurements, respectively; and scanning electron microscopy for ultrastructural analysis. Behavioral data were obtained through direct observation in the field and laboratory. Eggs were laid on the underside of leaves of two Lauraceae species. The first to third instars build frass chains, the fourth and the fifth instars build a conical shelter using a single leaf of the host plant. Before pupation, larvae bend its body ventrally and the pupae are incapable of movement. Descriptions, illustrations and photographs of egg, all five instars and pupa are given. The cephalic morphology and chaetotaxy of first instar were described and illustrated. Results are compared with other Charaxinae immature stages.

O presente trabalho visa fornecer subsídios para estudos morfológicos comparativos de Charaxinae neotropicais. Memphis moruus stheno (Prittwitz, 1865) é a segunda espécie neotropical de Anaeini e a primeira do gênero Memphis a ter sua morfologia detalhada. A morfologia externa é apresentada com descrições, ilustrações e imagens de microscopia eletrônica de varredura de estruturas da cabeça e apêndices cefálicos, região cervical, tórax e apêndices torácicos, abdome e genitálias masculina e feminina. A morfologia de M. moruus stheno é comparada com uma espécie do gênero proximamente relacionado Zaretis Hübner, [1819].
This study is intended to allow further comparative morphological studies on the Neotropical Charaxinae. Memphis moruus stheno (Prittwitz, 1865) is the second species of Anaeini and the first in the genus Memphis to have its morphology published in detail. The external morphology is presented with descriptions, line drawings and scan electron microscopy of the head and its appendages, cervix, thorax and its appendages, abdomen and both male and female genital armatures. Memphis moruus stheno is compared with a species of its closely related genus Zaretis Hübner, [1819].
