Triumfetta semitriloba Jacq. (Tiliaceae) is a tropical weedy species with floral nectaries and glands located at the margins of the leaves. The objectives of this work were to describe the anatomy of these secretory structures and to analyze their exudates. Sucrose, glucose, and fructose were identified in the product released by these secretory structures, characterizing them as nectaries. The nectaries of T. semitriloba are of a specialized type; a secretory epidermis comprised of pluricellular and multiserial nectariferous trichomes covers a nectariferous parenchyma, vascularized by phloem and xylem. A mass of phenolic compounds occurs in the head cells of the nectariferous trichomes of the foliar and bract nectaries; however, it is absent in trichomes of the floral nectary. The leaf and bract nectaries differed from those from flowers in their length and diameter. Structural features of the nectaries of T. semitriloba are typical of other taxa of the Malvales.Key words: foliar anatomy, histochemistry, Malvales, nectaries, Tiliaceae, Triumfetta semitriloba.

An update for the New World Croton sect. Lasiogyne is presented here. The names Croton subcompressus and C. rufo-argenteus are recognized as synonyms of C. compressus and C. tricolor, respectively. An issue between the names C. macrocalyx and C. janeirensis is resolved. In addition, lectotypes for 11 names are designated.

A New Species

A new amphipod species of the genus Elasmopus Costa, 1853 is described based on material collected from intertidal rocky shore, near the Suape Harbor, coast of the Brazilian state of Pernambuco. The new species may be recognized by the propodus of gnathopod 2 suboval, slightly tapering distally, palmar margin not defined by a stout seta, spine, or palmar corner, with a subdistal blunt tubercle, posterior margin covered by a dense fringe of plumose setae, and posterior margin of basis of pereopod 7 castelloserrate. This is the ninety-fifth species of the genus Elasmopus described worldwide, the most diverse genus in the family Maeridae Krapp-Schickel, 2008, and the eighth species recorded from Brazilian waters. An identification key to Brazilian species of Elasmopusis also provided.

Taxonomic Revision ◽  
Brazilian Species

A recent molecular based phylogeny (Borchsenius et al. 2012) redefined the genus Goeppertia Nees (1831: 337) to include all the subgenera of Calathea Meyer (1818: 6) proposed by Schumann (1902) with the exception of C. subgenus Calathea Körnicke (1862: 112). As a result, several species of Calathea recently described were transferred to Goeppertia (Braga 2014). Similarly, a taxonomic revision of the Brazilian species, currently carried out by the first author, led to the conclusion that Calathea polytricha Baker (1894: 497) should be combined in Goeppertia. This species features the synapomorphies of Goeppertia, such as simple inflorescences and corolla lobes straight to spreading, and belongs to Schumann’s subgenus Pseudophrynium Körnicke (1862: 113). During the taxonomic revision, other names have been considered synonyms and are typified here.

The Brazilian species of Bittacus Latreille (Mecoptera: Bittacidae) are reviewed and one new synonym is proposed (Thyridates willmanni Collucci & Amorin syn. n. of Bittacus diversinervis Souza Lopes & Mangabeira). Three new species are herein described: Bittacus cruzi sp. n. from Amazonas, Presidente Figueiredo and Manaus, B. ferreirai sp. n. from Bahia, Aracatu and B. varzeanus sp. n. from Amazonas, Tefé, bringing the current number of Bittacus species in Brazil to 18. Illustrations, comments, and distribution maps of each species are presented. An identification key to the Brazilian genera of Mecoptera and Bittacus species is also presented.

All life stages of Stenochironomus atlanticus Pinho & Mendes sp. n. are described and figured. The larva mines decaying leaves held in the water of several bromeliad species (Canistrum lindenii (Regel) Mez, Neoregelia laevis (Mez) L.B. Smith, Nidularium innocentii Lemaire, Vriesea philippocoburgii Wawra, and Vriesea vagans (L.B. Smith) L.B. Smith.) in the Atlantic Rain Forest in southern Brazil [Desterro Environmental Conservation Unit (Unidade de Conservação Ambiental Desterro – UCAD), Santa Catarina Island]. Stenochironomus atlanticus is the only species in the genus found in the phytotelmata habitat, and it apparently is restricted to this environment.
