Atopogyrodactylus n. gen. (Gyrodactylidae) is proposed for Atopogyrodactylus praecipuus n. sp. (type species by monotypy), a protandrous and oviparous gyrodactylid from the external surfaces of an unidentified bristlenose catfish Ancistrus sp. (Siluriformes: Loricariidae) from the head waters of the Rio Candeias in the State of Rondônia, Brazil. The new genus contains species morphologically similar to those of Nothogyrodactylus Kritsky & Boeger, 1991 as shown by members of both genera having accessory copulatory sclerites associated with the male copulatory organ (MCO). Atopogyrodactylus differs from Nothogyrodactylus by its species lacking haptoral bars and having a sclerotized haptoral plate overlying the ventral anchors. The new species most closely resembles Nothogyrodactylus amazonicus Kritsky & Boeger, 1991 by possessing a flared proximal filament on the egg and a single morphologically similar accessory copulatory sclerite associated with an allantoid MCO.

Telemiades Hübner, [1819] is currently comprised of 22 species and 14 subspecies distributed exclusively in the neotropics. The genus is defined by the morphological pattern of the uncus, apiculus, labial palpi and venation. However, some species have a uniform pattern of coloration making it difficult to establish their correct identity in some cases. The aims of the present study were to present a taxonomic revision of Telemiades Hübner, [1819] in order to provide a stable taxonomic hypothesis for the group, to describe the new species and to present diagnoses to help in species identification. According to the present study, Telemiades is now composed of 41 species. Fourteen new species are recognized and described. Three subspecies are here treated as valid species: T. marpesus (Hewitson, 1876) stat. rest., T. misitheus Mabille, 1888 stat. rest. and T. pekahia (Hewitson, 1868) stat. rest. Two synonyms are treated as valid species: T. insulsus (Draudt, 1922), stat. rev. and T. xantho Hayward, 1939 stat. rev. Five new synonyms are proposed: Plesioneura lamus Mabille, 1888 syn. nov. and Telemiades antiope tosca Evans, 1953 syn. nov. of T. antiope (Plötz, 1882), Echelatus punctatus Mabille & Boullet, 1917 syn. nov. of T. epicalus Hübner, [1819], Proteides nicola Plötz, 1882 syn. nov. of T. laogonus (Hewitson, 1876) and Eudamus phlius Plötz, 1881 syn. nov. of T. nicomedes (Möschler, 1879). To provide stability for existing names, six neotypes were designated for: Proteides amphion Geyer, 1832, Plesioneura compressa Möschler, 1877, Papilio avitus Stoll, 1781, Telegonus mygdon Möschler, 1877, Proteides aesopus Plötz, 1882 and Papilio corbulo Stoll, 1781; and 19 lectotypes for: Aethilla buffumi Weeks, 1906, Eudamus marpesus Hewitson, 1876, Telemiades misitheus Mabille, 1888, Pterygospidea pekahia Hewitson, 1868, Telemiades lurideolus Mabille, 1877, Eudamus laogonus Hewitson, 1876, Eudamus penidas Hewitson, 1867, Telemiades ceramina Herrich–Schäffer, 1869, Telemiades megalloides Schaus, 1902, Pythonides hoyti Weeks, 1906, Eudamus praestes Hewitson, 1876, Telemiades epicalus Hübner, [1819], Eudamus phasias Hewitson, 1867, Telemiades arcturus Herrich–Schäffer, 1869, Echelatus punctatus Mabille & Boullet, 1917, Eudamus centrites Hewitson, 1870, Telegonus gallius Mabille, 1888, Telegonus nicomedes Möschler, 1879, and Arteurotia meris Plötz, 1886.

Thraulodes marianoi sp. nov. is described, illustrated and diagnosed based on a single male imago from a subtropical forest at Pico do Marumbi State Park, in the protected area of Mananciais da Serra, state of Paraná, Brazil. Based on the dark coloration of legs and the large dark spot at base of forewing, T. marianoi sp. nov. is similar to species of the niger -group (Peruvian Amazonia) and to T. basimaculatus Giordano & Domínguez, 2005, a species endemic to Bolivia. The new species can be distinguished from all other species in the genus Thraulodes Ulmer, by the combination of following characteristics: (1) four cross-veins basal to bulla in forewing; (2) brown area covering about of proximal half of the forewing; (3) pleura violet; (4) middle and posterior femora yellowish washed with dark brown; (5) terga and sterna I–IV white washed with dark brown on posterior and lateral margin terga and sterna V–X dark brown; (6) penes short and wide with distolateral area, “ear-like” and poorly developed lateral pouch; (7) styliger plate triangular, median projection short and rounded on the apex. This new species represents the first record of the genus from the state of Paraná, Brazil.

This study aimed at evaluating effective methods for breaking the hard and insoluble spores of Ganoderma lucidum to recover functional biomolecules. Rupture techniques were evaluated such as manual maceration (RM), maceration with spheres of various materials (BR), and microwave exposure plus maceration with steel/chrome spheres (MBR1). Spore rupture was evaluated using UV-Vis spectroscopy, which showed vibrations of 2955, 1642, 1240, 1080 and 1746 cm-1 corresponding to changes in spore walls. The MBR1 extract contained the largest amounts of carbohydrates (19.80 mg.g-1 spores) and polyphenols (2.21 mg.g-1 spores), whereas the BR extract had higher antioxidant activity (57.22%Inb DPPH). The MBR1 and BR extracts contained 62.2 and 73.5% glucose, respectively. Both methods also involved significant extraction of carbohydrates and proteins. The best way to extract biomolecules from spore walls is to perform a microwave heat treatment and break the walls with steel/chrome spheres; this produces large quantities of carbohydrates with antioxidant properties.

El objetivo de este estudio fue evaluar varios métodos de ruptura de las esporas de Ganoderma lucidum y extraer sus propiedades bioactivas. Para este propósito se evaluaron diferentes técnicas de rompimiento como: la maceración manual (RM), la maceración con esferas de diversos materiales (BR) y la exposición a microondas junto la maceración de las esporas con esferas de acero/cromo (MBR1). La ruptura de las esporas fue evaluada por espectroscopia UV-Vis, la cual mostró que las vibraciones 2955, 1642, 1240, 1080 y 1746 cm-1 correspondieron a cambios estructurales en las paredes de las esporas. El extracto MBR1 presento el mayor contenido de carbohidratos (19,80 mg.g-1) y polifenoles (2,21 mg.g-1), mientras que el extracto BR tuvo una mayor actividad antioxidante (57,22% Inb DPPH). Los extractos MBR1 y BR también presentaron en el análisis de monosacáridos un 62,2 y 73,5% de contenido glucosa. Como conclusión la mejor metodología para extraer biomoléculas de las paredes de las esporas de G. lucidum fueron el tratamiento térmico con microondas y la ruptura de las paredes con esferas de acero/cromo, porque este proceso permitió la extracción de una mayor cantidad de carbohidratos con posibles propiedades antioxidantes.

Loricalepis has been known from only three collections from the upper Rio Negro, in Amazonas, Brazil, and the Río Guainía basin, in Colombia, all belonging to a single species, L. duckei. Its capsular fruits and cochleate, tuberculate seeds suggest its relation to pantropical “core Melastomeae”, but it does not have a particularly close morphological connection with any other genus of the tribe. Here we describe and illustrate a second species in the genus, Loricalepis atlantica, recently collected in white sand vegetation near the coast of Bahia. Although we have not been able to sequence DNA from the new species, we place it in Loricalepis due to a long list of characters that it shares with L. duckei. Both are shrubs or small trees with scalariform indumentum on the stems and leaves; thick-cartilaginous, crenulate-serrulate and paleaceous-ciliate leaf margins; persistent acute and seta-tipped sepals; glandulose-ciliate petal margins; glabrous and subisomorphic stamens, these with the connective not at all or only shortly prolonged and ventrally bilobed; and the ovary apex with a crown of scales surrounding the style. lightface differs from L. duckei by 5-merous flowers (vs. 4-merous in L. duckei), the hypanthium covered with minute scalariform trichomes (vs. glabrous), light-pink petals (vs. white), purple anthers (vs. white), and 5-celled ovary (vs. 4-celled). The new species is known from only one locality, in an extremely endangered vegetation type. Its discovery highlights the need for sustained floristic studies of forest remnants in northeastern Brazil.
