The saccoderm desmids Spirotaenia endospira and Spirotaenia closteridia, species thus far unknown from the southern hemisphere, are described from Serra da Jiboia, northeast Brazil. Spirotaenia filiformis sp. nov. was also recorded in this area and described as new species. In the present study, Spirotaenia species were collected from Alcantarea nahoumii tanks, an endangered Brazilian bromeliad species. The newly described S. filiformis is primarily characterized by a high cell length to breadth ratio (17–31) and a parietal chloroplast with 3.5–8.5 turns. All three species were discussed for possible affiliations with other Spirotaenia taxa. From this study, the knowledge on genus Spirotaenia in Brazil has been expanded to four species currently confirmed: Spirotaenia closteridia, S. condensata, S. endospira, and S. filiformis.

A New Species

Some regions, such as the Northeast Region of Brazil, are still severely understudied and the trichopteran fauna of this region is not entirely known, mainly in areas from Cerrado and Caatinga biomes. Currently, 25 species have been reported from Piauí State, but most of these records are concentrated from one locality. This study aimed to update the knowledge of Trichoptera diversity in this state, including the description of a new species and new geographic records for the Northeast region and Brazil. The samples were collected in seven municipalities, using various traps. Specimens were also received from the municipality of Bom Jesus. Thirty-two species were added for Trichoptera fauna of Piauí, 14 of these represent new records for Northeast Brazil; furthermore, Neotrichia palma Flint 1982 is a new record for Brazil. Additionally, a new species, Cernotina longa sp. nov., is describe and illustrate, being the third nominal record of the genus for the Caatinga biome. Thus, with the contribution of this study, 57 species, 20 genera and seven families of caddisflies are known for Piauí State.

AbstractTwo new corticolous lichen species are described, Lepraria nothofagi Elix & Kukwa (atranorin, strepsilin, porphyrilic acid) from Argentina and L. stephaniana Elix, Flakus & Kukwa (4-O-methylleprolomin, zeorin, salazinic acid, unknown terpenoid) from pre-Andean Amazon forest of Bolivia. In addition, the paper presents new records of 16 species of Lepraria from South America. Lepraria adhaerens, and L. diffusa are new to the Southern Hemisphere; L. borealis is new to South America; L. alpina is new to Chile, Colombia, Peru and Venezuela; L. caesioalba (chemotype I) is new to Venezuela, L. lobificans new to Argentina, L. pallida new to Peru, and L. sipmaniana new to Bolivia and Chile. The Chilean records of L. membranacea appeared to belong to L. sipmaniana. Therefore, the number of Lepraria spp. known at present from South America is enlarged to 27 species. 4-O-methylleprolomin is reported for the second time from lichens.

First Time

The present study reviews the taxonomy of the marine gastropods belonging to the family Eulimidae Philippi, 1853 from the continental slope off Northeast Brazil. The genera Abyssoaclis Barros, Mello, Barros, Lima, Santos, Cabral & Padovan, 2003 and Aclis Lovén, 1846 were not treated here. A total of 20 taxa were identified in this region, excluding Eulima hebes Watson, 1883, a species with a doubtful classification in Eulimidae. The species were assigned to the following genera: Costaclis Bartsch, 1947, Eulima Risso, 1826, Fusceulima Laseron, 1955, Melanella Bowdich, 1822, Ophieulima Warén & Sibuet, 1981, Sticteulima Laseron, 1955, Thaleia Warén, 1979, and Umbilibalcis Bouchet & Warén, 1986. The genera Sticteulima, Ophieulima and Umbilibalcis are reported for the first time in the southwestern Atlantic. Four species represent new records for the southwestern Atlantic. A redescription of the shell morphology is provided for: Costaclis egregia (Dall, 1889b), Melanella doederleini (Brusina, 1886), and Umbilibalcis lata (Dall, 1889b). Additional information to the original description are reported for other species. Melanella sarissa is considered as a synonym of Melanella cinca Dall, 1927. Six new species are described: Eulima cracentis sp. nov., Melanella paraabida sp. nov., M. adiastalta sp. nov., M. anapetes sp. nov., Sticteulima cabrali sp. nov. and S. canopusensis sp. nov. Lectotypes are designated for: Costaclis hyalina, C. egregia, Eulima ephamilla (Watson, 1883), E. psila and E. (?) hebes. Eulima sp. 1, Melanella sp. 1 and Melanella sp. 2 are potential new species, but the scarcity of material precludes a formal description at this moment.

Abstract:New records of 15 Lepraria species from South America are presented. Two species are newly described from the Bolivian Andes: Lepraria achariana Flakus & Kukwa (major compounds: lecanoric, angardianic/roccellic acids and anthraquinones) and L. neojackii Flakus & Kukwa (major compounds: porphyrilic, angardianic/roccellic, cf. rangiformic acids and anthraquinone). Lepraria impossibilis, L. lecanorica and L. rigidula are reported as new for the Southern Hemisphere, L. alpina, L. aff. caesiella and L. squamatica as new to South America, and other species as new to several countries (Argentina, Bolivia, Brazil, Peru, Uruguay). In addition, two putative, undescribed species are discussed. Chemistry, ecology and general information concerning distribution of the species are presented, and the differentiation of some critical taxa discussed. A provisional key to Lepraria in South America is provided.

Forty-one species in five genera of bitentaculate cirratulids are reported from new collections from South America, the Southern Ocean, and seas around Antarctica. Twenty-seven species are new to science; one new genus is described to deal with some species formerly identified as Chaetozone. New records, synonymies, and new combinations are reported. Previous records are reviewed with type specimens of most species reexamined and redescribed. The sub-Antarctic species Aphelochaeta cincinnata (Ehlers, 1908) does not occur in Antarctica: the numerous published records of this species instead belong to several new species. The types of Tharyx epitocus Monro, 1930, and Tharyx fusiformis Monro, 1939, have spines in posterior setigers and are referred to other genera. Among the 41 species treated in this study, 11 belong to Aphelochaeta, eight are new; eight species belong to Caulleriella, six are new; six species belong to Chaetocirratulus n. gen., three are new; 12 species belong to Chaetozone, seven are new; and four species belong to Tharyx, three are new. Numerous samples come from slope and abyssal depths, expanding our knowledge of the distribution of Southern hemisphere deep-sea cirratulids.

Second Category

The recently proposed order Tethyida is characterized by the presence of megasclere styles, tylostyles or oxeas arranged in tracts ending as bouquets at or near the surface, and microsclere euasters. Two new species are described from the shallow coastal reefs (0–10 m) of Bahia, Brazil. Timea kamasary sp. nov. is represented by thin sciaphylous specimens with three categories of spicules: tylostyles, spined spheroxyasters and spined/smooth oxyasters in varied sizes. This species differs from Timea unistellata (Topsent, 1892) by having a different category of oxyasters. Tethya bitylastra sp. nov. is characterized by having strongyloxeas I and II, spherasters, oxyasters I and II, strongylasters and two categories of tylasters. This new species differs from Tethya maza Selenka, 1879 by having a second category of tylaster. Furthermore, we present taxonomic appointment for Timea berlincki (Leite, Fonseca, Leal & Hajdu, 2015) and Tethya maza and the first record of Timea stenosclera (Hechtel, 1969) for the Southwest Atlantic.

The World

The family Hormathiidae Carlgren, 1932 is one of the largest families of sea anemones with ca. 130 species around the world, mostly in the deep sea. In Brazilian waters, only six species have been reported so far. Herein we record four hormathiids from deep-sea sites at the Potiguar Basin continental slope at Northeast Brazil. Monactis vestita (Gravier, 1918) and Phelliactis robusta Carlgren, 1928 represent the first records of both genera for the Brazilian coast. The new species Paraphelliactis labiata n. sp. is described. We also found another species of the genus, Phelliactis sp. The new species possesses fourth and fifth cycles of incomplete mesenteries, unlike all other Paraphelliactis species. These results increase the total number of hormathiid sea anemones in Brazil to nine and contribute to the knowledge of the Brazilian deep sea, still little explored.

Malaise Traps

The objectives of this study were to carry out a survey of families of Hymenoptera, with emphasis on Ichneumonidae, in an area of Caatinga, and register the occurrence of new species, if any, for the biome. Samples were taken with Malaise traps between September and November 2008 in a native area of vegetation of Serra do Lima, municipality of Patu, Rio Grande do Norte, Brazil. 7,562 hymenopterans, from 11 superfamilies and 31 families, were collected. The most abundant superfamilies were: Chalcidoidea (2,887 specimens / 38.33% of the total), Platygastroidea (1,572 / 20.87%) and Vespoidea (1,131 / 15.02%) which constituted more than 70% of the captured hymenopterans. A total of 160 specimens of Ichneumonidae from 17 subfamilies were sampled, of which four are new records for Rio Grande do Norte: (Lycorininae, Nesomesochorinae, Phygadeuontinae and Tryphoninae). Altogether, 26 genera were recognized, with 16 new records for the state. Cryptophion espinozai Gauld & Janzen (Campopleginae) and Labena marginata Szépligeti (Labeninae) were registered for the first time in Caatinga. The obtained data demonstrate a considerable diversity of the studied groups in this area and also affirms the necessity of additional studies to establish the richness of this fauna in a more extensive and conclusive way.
