Navicordulia aemulatrix sp. nov. (Odonata, Corduliidae) from northeastern Santa Catarina State, Brazil

Navicordulia aemulatrix sp. nov. (holotype male deposited in MZSP: Brazil, Santa Catarina State, [São Bento do Sul municipality, 26°14'58"S, 49°22'59"W], [railroad station] Rio Vermelho, II.1952) is described and illustrated based on three males. The long cercus (2.9-3.2 mm) places this species in the longistyla-group together with N. kiautai, N. longistyla and N. nitens but it differs from them mainly by the shape of cercus, with carinated part occupying 0.33 of cercus total length, and also by dorsal, ventro-medial and ventro-lateral tubercles developed. An unusual process on tergal portion of prothorax is reported for the first time in Navicordulia. The rate of description of new species of South American 'Corduliidae' is discussed. A map with records of Atlantic Forest Navicordulia species and a list of Brazilian corduliids by state are also presented.

External morphology of immature stages of Zaretis strigosus (Gmelin) and Siderone galanthis catarina Dottax and Pierre comb. nov., with taxonomic notes on Siderone (Lepidoptera: Nymphalidae: Charaxinae)

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).

Saccamoeba lacustris, sp. nov. (Amoebozoa: Lobosea: Hartmannellidae), a new lobose amoeba, parasitized by the novel chlamydia 'Candidatus Metachlamydia lacustris' (Chlamydiae: Parachlamydiaceae).

An amoeba isolated from an aquatic biotope, identified morphologically as Saccamoeba limax, was found harbouring mutualistic rod-shaped gram-negative bacteria. During their cultivation on agar plates, a coinfection also by lysis-inducing chlamydia-like organisms was found in some subpopulations of that amoeba. .Here we provide a molecular-based identification of both the amoeba host and the two bacterial endosymbionts. Analysis of the 18S rRNA gene revealed that this strain is the sister-group to Glaeseria, for which we proposed the name Saccamoeba lacustris. The rod-shaped endosymbiont was identified as a member of Variovorax paradoxus group (Comamonadaceae, Beta-Proteobacteria). No growth on bacteriological agars was recorded, hence this symbiont might be strictly intracellular. The chlamydia-like parasite was unable to infect Acanthamoeba and other amoebae in coculture, showing high host specificity. Phylogenetic analysis based on the 16S rDNA indicated that it is a new member of the family Parachlamydiaceae (order Chlamydiales), for which we proposed the name 'Candidatus Metachlamydia lacustris'.
