AIM: This study aimed at to evaluate the influence of habitat heterogeneity on the attributes of richness, abundance, diversity and equitability of Chironomidae assemblage and also the biological differences in faunistic composition related to each microhabitat. METHODS: The sampling was performed in summer (February) and winter (August) 2010, with Surber sampler, in three headwaters streams at Atlantic Forest, in southern Brazil. RESULTS: In the total 6,429 Chironomidae larvae were identified and classified into 96 taxa belonging to Chironominae, Tanypodinae and Ortocladiinae subfamilies. Among the microhabitats, the highest richness was observed in the deposits of litter, and the highest number of exclusive species took place in the pool regions. CONCLUSIONS: Thus, the composition and structure of the Chironomidae assemblage are directly related to the availability and heterogeneity of habitats in streams.

A New Species

A new species of Paratelmatobius is described from the Brazilian Atlantic Forest in the state of Paraná in southern Brazil. Adults, tadpoles, and vocalizations are described. Morphological traits and phylogenetic analysis place the new species within the P. cardosoi group. The new species can be readily distinguished from its congeners by its advertisement call being composed of two note types and comprised of a series of 2–4 notes. The new species is classified as an explosive breeder, having reproductive activity strongly associated with heavy rainfall. This discovery highlights the importance of intensifying survey efforts in the Atlantic Forest, a domain with high levels of species richness and endemism.

The feeding strategy of Characidium lanei and C. pterostictum was studied in the "Cabral" stream, a coastal stream of the Atlantic Forest, in southern Brazil. The samples were taken using electric fishing between March/95 and February/96. We studied about 15 stomach contents for each species in each season of the year. The stomach contents of the studied species were composed of 39 different food items, 28 in C. lanei and 24 in C. pterostictum. Chironomidae larvae and Ephemeroptera nymph were the most important items for C. lanei, except in the summer when Acarina and not identified Arthropoda were the most important items. Chironomidae and Simulidae larvae were the most important items in C. pterostictum. These results indicated an insectivorous habits and opportunist feeding strategy to C. lanei and C. pterostictum with several items rare or not very frequent.

Abstract:Isolated pioneer trees have been shown to increase the deposition of animal-dispersed seeds. The effect of gender on seed rain has not yet been investigated, and this study aimed to evaluate whether female and male plants of a pioneer dioecious zoochoric tree differ with respect to the seed rain under their canopies. Seed rain was evaluated for 13 mo, from October 2009 to October 2010, in secondary vegetation of the Atlantic forest in southern Brazil. We used 60 seed traps (0.5 m2): 40 traps under the crowns of 40 Myrsine coriacea (Primulaceae) trees (20 male and 20 female individuals) and 20 at sites without trees. We found 365071 diaspores belonging to 115 morphospecies from 37 families, and 38.3% of the morphospecies were trees, most of them zoochoric. The female trees accumulated a greater number of diaspores and species richness than male trees. The male trees accumulated a higher number of seeds and species than areas without trees. This study shows that sites containing female and male trees of M. coriacea and sites without trees differed significantly in terms of seed rain, and there is a gender effect in this dioecious, pioneer tree species because female plants promote an increase in the richness and abundance of diaspores.

A total of 286 male specimens of Manota from 38 different collecting sites in the Brazilian Atlantic Forest were analysed. They belong to 32 different species, including 20 described as new to science and 12 recognized as previously described species. The new species are M. abbreviata sp. n., M. atlantica sp. n., M. carioca sp. n., M. cavata sp. n., M. hirta sp. n., M. lamasi sp. n., M. lanei sp. n., M. nordestina sp. n., M. oliveirai sp. n., M. paniculata sp. n., M. papaveroi sp. n., M. periotoi sp. n., M. perparva sp. n., M. pseudoiota sp. n., M. rostrata sp. n., M. sanctavirginae sp. n., M. securiculata sp.n., M. silvai sp. n., M. tavaresi sp. n. and M. unispinata sp. n. The taxonomic context of the newly described species is discussed. Manota palpalis Lane, 1948, the type of which is considered lost, is redescribed and discussed, based on the original description, the original illustrations, and the type-locality. Our specimens of the previously described species belong to M. aligera Hippa, Kurina & Sääksjärvi, 2017, M. anfracta Hippa & Kurina, 2013, M. appendiculata Hippa & Kurina, 2013, M. caribica Jaschhof & Hippa, 2005, M. diversiseta Jaschhof & Hippa, 2005, M. micula Hippa & Kurina, 2013, M. panda Hippa & Kurina, 2013, M. pustulosa Hippa, Kurina & Sääksjärvi, 2017, M. quantula Hippa & Kurina, 2013, M. serrulata Hippa, Kurina & Sääksjärvi, 2017 and M. subaristata Kurina, Hippa & Amorim, 2017. Among the species dealt with here, ten have a wide distribution in South America or the Neotropics, six are known from only a single site, nine are widespread along the Atlantic Forest, and seven are known only from southern Brazil/northwestern Argentina. A discrepancy between the distribution patterns of Manota species and the general areas of endemism known for flies in the Atlantic Forest is discussed, and a non-destructive sequencing reverse workflow protocol for Manota specimens proposed.        Including the species described here, the Neotropical region closely approaches the Oriental region in terms of the number of described species (92 and 102, respectively), while the genus now includes 300 species worldwide.

Occurrence of chironomid larvae living inside fallen-fruits in Atlantic Forest streams, Brazil - The Chironomidae larvae explore a wide variety of habitats and kinds of food. In this study we reported the use of fallen-fruits by chironomid larvae in low order streams in the Brazilian Atlantic Forest. We found chironomid larvae mining fruit tissue of 12 tree species. Seven morphospecies of Endotribelos were identified, including the species E. albatum and E. grodhaus found for the first time in Brazil. Our results suggest that larvae of Endotribelos are the commonest insect group living inside fallen-fruits in streams.

Two New Species

Two new species of the genus Austroleptis Hardy, so far known only from Australia and Chile, are described from the Brazilian Atlantic Forest—A. longirostris nov. sp. and A. papaveroi nov. sp. The species share clear apomorphic features of the genus, as the subdivision of female tergite 8. Both new species share a distinctive wing pattern, and a flagellomere 1 that is as wide as the more distal flagellomeres, features that clearly differentiate them from the Chilean and Australian species. It is likely that the Brazilian species compose a small clade apart from the Chilean species of the genus. A. longirostris nov. sp. has a particular long proboscis, even for the standards of non-tabanid tabanomorphs, while A. papaveroi nov. sp. has a stump on M3. The scutum coloration also helps to discriminate between both species. This is an additional example of a group in southern Brazil with southern temperate connections, i.e., involving southern Chile and Argentina and either Australia, New Zealand or both. Additional records and illustrations of Austroleptis atriceps Malloch and           A. penai Nagatomi & Nagatomi from Chile are provided.
