ABSTRACT
The genus Praepedaliodes Forster, 1964, the only representative of the mega-diverse mostly Andean Pedaliodes complex lineage in the Brazilian Atlantic Forest, is revised. Prior to this study, four species were known, P. phanias (Hewitson, 1862), P. granulata (Butler, 1868), P. amussis (Thieme, 1905) and P. exul (Thieme, 1905). Here, a further six are described, all from SE Brazil, expanding to 10 the number of species in this genus. Lectotypes are designated for P. phanias, P. granulata and P. amussis. The genus is most diverse in the Serra da Mantiqueira (São Paulo, Rio de Janeiro, Minas Gerais) and in the Serra Geral (Paraná, Santa Catarina) with seven species occurring in both ranges. Praepedaliodes phanias is the most widespread species and the only one found in the western part of the Atlantic Forest; only this species and P. duartei Dias, Dolibaina & Pyrcz n. sp. occurring to near sea level. Other species, P. zaccae Dolibaina, Dias & Pyrcz n. sp., P. francinii Freitas & Pyrcz n. sp., P. sequeirae Pyrcz, Dias & Dolbaina n. sp., P. landryi Pyrcz & Freitas n. sp. and P. pawlaki Pyrcz & Boyer n. sp. are strictly montane and the highest species richness is reached at 1400-1800 m. One species, P. sequeirae n. sp., is a narrow endemic found only at timberline in the Agulhas Negras massif above 2300 m. Immature stages are described for two species, P. phanias and P. landryi n. sp. Molecular data (barcode region of cytochrome oxidase, subunit I) and adult morphology, including male and female genitalia, support the genus as monophyletic, belonging to a predominantly Andean clade of the Pedaliodes Butler, 1867 complex. Morphological evidences, in particular female genitalia comparative analysis, indicate the genera Physcopedaliodes Forster, 1964 and Panyapedaliodes Forster, 1964 as possibly the closest relatives to Praepedaliodes. Molecular data are inconclusive in this respect.

A new satyrine species in the subtribe Euptychiina, Euptychia atlantica Nakahara & Freitas sp. nov., is described from the Atlantic coastal forest of Brazil. Based on the existing museum specimens, E. atlantica sp. nov. is known from the coastal montane forests of Rio de Janeiro to south Bahia, a unique biogeographical region which is undergoing rapid degradation. Illustrations of adults and their genitalia, as well as a distribution map, are provided herein, in addition to a discussion of the relationships and conservation status of the new species.

A new genus is described for Neonympha griphe C. Felder & R. Felder, 1867, to contribute toward a revision of the polyphyletic genus Euptychoides Forster, 1964. Based on DNA sequence data, Graphita Nakahara, Marín & Barbosa, gen. nov. is strongly supported as a member of a clade of predominantly southeastern Brazilian taxa, in which it is weakly supported as sister to a well-supported clade containing Pharneuptychia Forster, 1964, Moneuptychia Forster, 1964 and the E. castrensis (Schaus, 1902) species complex. The data show that Graphita griphe comb. nov. is not related to other Euptychoides and not very closely related to any other sampled euptychiines, and thus support the description of this new genus. In addition, we provide morphological illustrations and a distribution map for this taxon based on museum specimens.

We provide the first information on the morphology of the immature stages (egg, larva, and pupa), oviposition and larval behavior, and host plant, for the Brazilian crescent butterfly Ortilia liriope (Cramer), based on material from Santarém Municipality, Pará State, Northern Brazil. Females of O. liriope lay eggs in clusters. After hatching, larvae eat the exochorion and remain gregarious in all but the final instar. The host plant recorded in the study site is Justicia sp. (Acanthaceae). Despite the scarcity of data on the immature stages of Neotropical Melitaeini, we can already say that some morphological and behavioral traits observed in the immature stages of O. liriope are also present in all known genera in this tribe.

The pierid Charonias theano (Boisduval), an endangered butterfly species, has been rarely observed in nature, and has not been recorded in the state of São Paulo in the last 50 years despite numerous efforts to locate extant colonies. Based on museum specimens and personal information, C. theano was known from 26 sites in southeastern and southern Brazil. Recently, an apparently viable population was recorded in a new locality, at Serra do Japi, Jundiaí, São Paulo, with several individuals observed during two weeks in April, 2011. The existence of this population at Serra do Japi is an important finding, since this site represents one of the few large forested protected areas where the species could potentially persist not only in the state of São Paulo, but within its entire historical distribution.

A strain of Aspergillus fumigatus isolated from soil was able to produce biomass and high amylase activities in media containing alpha-methyl-D-glucoside (alphaMG), a synthetic analogue of maltose, as the only carbon source. alphaMG was a more effective inducer than starch and maltose at the same concentration: alphaMG cultures produced about 3 times more alpha-amylase and glucoamylase activity than starch cultures. Maximum production of alpha-amylase (60 U/mg) and glucoamylase (130 U/mg) was obtained in 8-10 days alphaMG cultures.
