Crinoid faunas from the Lower Devonian of South America are poorly known. Two new taxa are described from the Emsian Icla Formation at Cerro Kochis in the Cochabamba Department: the rhodocrinitid, Lutocrinus boliviaensis n. gen. n. sp. and Griphocrinus pirovanoi n. sp. Two additional camerates are reported from the Emsian Belèn Formation of the Altiplano region in the La Paz Department, including Ctenocrinus branisai n. sp. and Boliviacrinus isaacsoni McIntosh, 1988. In addition, a specimen of the blastoid, Pachyblastus dicki Bremier and Macurda, 1972, was recovered from the Altiplano region. These crinoids and material previously collected by Leonardo Branisa, including specimens of C. branisai n. sp., Apurocrinus sucrei McIntosh, 1981, B. isaacsoni McIntosh, 1988, and L. boliviaensis n. sp., are described and revised. The specimens give new insights into the Lower Devonian Malvinokaffric Realm of Bolivia, a relatively new frontier in crinoid paleontology.

Review of specimens and names of Faramea Aubl. (Rubiaceae, Coussareeae) has required new nomenclatural combinations, clarified the identities of some previously described species, and discovered some new taxa. Here we transfer two Faramea names, F. suaveolens Duchass. and F. panurensis Müll. Arg., to Coussarea Aubl.; review the identities of F. cuencana Standl., F. multiflora A. Rich., F. oblongifolia Standl., F. parvibractea Steyerm., F. spathacea Müll. Arg. ex Standl., and F. suerrensis (Donn. Sm.) Donn. Sm.; lectotypify F. multiflora and F. panurensis; transfer to Faramea and lectotypify Rudgea scandens K. Krause; and describe 13 new species and two new subspecies: F. camposiana C. M. Taylor of Ecuador and Peru, F. foreroana C. M. Taylor of Colombia, F. fosteri C. M. Taylor of western South America, F. galerasana C. M. Taylor of Ecuador, F. grayumiana C. M. Taylor of Central America, F. kampauicola C. M. Taylor of Ecuador and Peru, F. neilliana C. M. Taylor of western South America, F. premontana C. M. Taylor of Ecuador, F. quijosana C. M. Taylor of Ecuador, F. ramosiana C. M. Taylor of Colombia, F. reyneliana C. M. Taylor of Peru, F. stoneana C. M. Taylor with two subspecies from Central and western South America, F. suerrensis subsp. miryamiae C. M. Taylor from Colombia, and F. vernicosa C. M. Taylor of Ecuador and Peru.

The Body ◽  

In 1952 I had the opportunity of investigating about 70 slab cists in the province of Munecas, Bolivia. Among the vessels found in the graves there were a few goblets provided with a tubular protuberance on one side. As my collections and personal outfit are still detained by the Bolivian authorities, the appearance of these vessels is illustrated here only by a drawing of a vessel taken over by the Museo Nacional “Tihuanacu,” La Paz (Fig. 50). A similar but undecorated vessel from the same region, Tacacacoma, is published by Schmidt (1929: 256, and Fig. 2). On the latter vessel the tubular protuberance is joined to the body of the goblet by two bare. Other minor variations in vessels of this type appear in the shape of the goblets and in the shape and placing of the tubular protuberance. Sometimes, for instance, the tube is longer than on the vessels depicted here and very often a raised human face is found on the outer side opposite the tube.

An extensive study was made on the moss flora of the Bío-Bío Region (VIII Región) in south-central Chile in 2001-2003. Collections were made in all four provinces of the region: Arauco, Bío-Bío, Concepción and Ñuble. Approximately 265 localities in the region were explored with over 6,000 mosses collected in the four provinces. The mosses of this region had not previously been studied to any great extent and with part of the region’s environment being destroyed by the construction of several dams on one of the major rivers, the Bío-Bío, the study of this area seemed of utmost importance. Thus far, a total of 20 taxa were found which are new to Chile, making a total of 877 known for the country, with four new taxa known for South America. An additional 87 taxa are reported new only to the Bío-Bío Region. That number, together with some new records from the recent literature, increases the total for the Region from 190 to 300. It was determined from the 87 new taxa for the Bío-Bío Region that the majority (41) represent northern extensions of taxa, while a much smaller number (10) represent southern extensions. The remainder (36) fill in a gap in the distribution of the taxa between the northern and southern parts of the country. Many difficult species still remain to be identified and the number of species new to science, to Chile and to the Bío-Bío Region, is certain to increase when the remaining specimens are identified.

A new genus of gnaphosid spiders, Almafuerte, gen. nov., is described for seven species from Southern South America. The new genus is diagnosed by a conspicuous retrolateral tegular projection on the male palp, and by having three teeth on the cheliceral retromargin. It comprises six species from Argentina, A. peripampasica sp. nov. (type species), from Central Argentina, also present in Uruguay, A. kuru sp. nov., from Santiago del Estero, A. vigorosa sp. nov., from Corrientes, A. goloboffi sp. nov., from Salta and Jujuy, A. remota sp. nov., from Santiago del Estero and Mendoza, and A. giaii (Gerschman & Schiapelli) comb. nov., here transferred from Echemus, from Santa Fe (the female is here described by the first time); and one species from Bolivia, A. facon sp. nov., from Cochabamba. Hypotheses of relationships of the new taxa are briefly discussed, in the context of the previously proposed groupings: the subfamilies Echeminae and Drassodinae (sensu Platnick 1990) and the “Echemus group” (sensu Murphy 2007).

Twenty-five new species of neotropical Limacodidae, primarily from Central America, are described. The majority of these species (n=15) are from Parasa and Natada generic complexes, both presently known to contain only spiny caterpillars. In the Parasa complex, they include: Parasa figueresi, new species, Parasa joanae, new species, Parasa sandrae, new species, Parasa shirleyae, new species, Euclea mesoamericana, new species, Euclea zurquicola, new species, Euclea microcippus, new species, Euclea costaricana, new species, Euclea gajentaani, new species, Euclea josepsi, new species, Talima beckeri, new species, Talima weissi, new species, and Talima erojasi, new species. In the Natada complex, two new taxa are Natada delgadoi, new species, and Natada varablancana, new species. In a generic complex with hairy caterpillars, the Phobetron complex, six new taxa are: Phobetron guzmanae, new species, Isochaetes dwagsi, new species, Isochaetes kenjii, new species, Isochaetes heevansi, new species, Isochaetes tapantiensis, new species, and Vipsophobetron davisi, new species. In the Prolimacodes and Perola complexes, caterpillars are known to be smooth. New species in the Prolimacodes complex are Prolimacodes montanus, new species, and Dichromapteryx saborioi, new species, while the Perola complex includes Perola aenea, new species, and Epiperola browni, new species. Euclea microcippus, Parasa sandrae and Vipsophobetron davisi are the smallest species known to occur in their genera. Euclea mesoamericana and Parasa figueresi are relatively common in collections but have been mistakenly grouped with Euclea cippus (Cramer) and Parasa schausi Dyar, respectively. Each was reported from both Central and South America, but is now considered to be limited to South America. Talima weissi is closely related to the Mexican species T. assimilis (Dyar), sharing both a detachable clump of hairs on 8 th abdominal segment in males and large ductus seminalis, which hold the hairs, in females. Larval descriptions or hostplants are presented for P. sandrae, P. joanae, E. mesoamericana, E. gajentaani, T. beckeri, T. weissi, I. dwagsi, I. kenjii, I. heevansi, and V. davisi. Euclea zurquicola, E. josepsi, T. erojasi, N. delgadoi, N. varablancana, P. guzmanae, I. tapantiensis, and E. browni are known from only one locality, each in Costa Rica, while the last four are known only from unique specimens.

Two new species of Begonia (Begoniaceae) from Andean South America are described and illustrated. Begonia heliantha Tebbitt is classified in B. sect. Eupetalum and is known from the Puno Region of Peru and has also been tentatively identified from photographs taken in La Paz Department of Bolivia. Begonia urubambensis Tebbitt is affiliated with a group of species currently classified in B. sect. Knesebeckia. This group of species is informally named here the B. acerifolia group. Begonia sect. Knesebeckia is polyphyletic since the B. acerifolia group does not include the type species of the section. Ongoing research aims to recircumscribe this section. Begonia urubambensis is not assigned to a section given the changes needed to the sectional classification system. Begonia urubambensis is a narrow endemic of La Convención Province (Cusco Region) of Peru. Begonia heliantha is assigned the IUCN category of Data Deficient (DD), while B. urubambensis is assigned the IUCN category of Vulnerable (VU-D2).

AbstractA remarkable fossil assemblage composed of five gastropod taxa is described from the Early Miocene of Santa Cruz (Patagonia, Argentina) in southernmost South America. The assemblage includes extinct and living genera South America, and on geographic distributions and represent background new information on spatial and across time distributions as well as identification of new taxa. A new taxon,Patagocharopa enigmatican. gen. n. sp., is tentatively assigned to Charopidae.Gastrocopta patagonican. sp. (Vertiginidae) represents the oldest record ofGastrocoptain Argentina and the southernmost record for the Americas.Punctum patagonicumn. sp. (Punctidae) represents the first record ofPunctumfor continental South America, and characterized by a protoconch with traces of axial costulae and a teleoconch with strong radial ribs.Zilchogyra miocenican. sp. is the first Miocene record of the charopid genusZilchogyra. Fragments of a possibleScolodonta(Scolodontidae) are recorded. Overall, the assemblage represents an important and useful paleoenvironmental tool. This fauna suggests that a more temperate and humid environment than today—with a more dense vegetation cover—was prevalent at this site during the Early Miocene.

In the General Catalogue of the Homoptera (METCALF, 1967)contains 36 genera and 215 Neotropical species, including north ofMexico distributed within 10 tribes (two genera and six species inEuscelini, one genera and one species in Colladonini, one genusand one species in Goniagnathini, four genera and 52 species inAcinopterini, one genus and one species in Cicadulini, four generaand 80 species in Scaphytopiini, five genera and 32 species inBalcluthini, one genus and one species in Macrostelini, three   genera and five species in Platymetopiini and 14 genera and 82 species in Scaphoideini). However, since 1967 many papers on Neotropical Deltocephalinae have been published including classification and nomenclatorial alterations, new taxa and geographical distribution. The complete bibliography of the leafhopper literature up to 1955 can be found in the General Catalogue of the Homoptera, Fascicle VI, Part 10 (METCALF, 1962-1968). OMAN et al. (1990) published a complete list of the world genera of Cicadellidae and the bibliography between 1955-1985. In this work are recorded 21 Neotropical subfamilies, 16 Neotropical tribes and 184 Neotropical genera (one genus in Acinopterini, one genus in Cicadullini, one genus in Cerrillini, six genera in Hecalini, one genus in Luheriini, two genera in  Doraturini, two genera in Stenometopiini, four genera in Scaphytopiini, two genera in Platymetopiini, six genera in Scaphoideini, one genus in Balcluthini, seven genera in Macrostelini, two genera in Opsiini, one genus in Penthimiini, 40 genera in Deltocephalini and 107 genera in Athysanini); eight genera without references about the tribe. Another subfamily and genus were added by GODOY & WEBB (1994). This catalogue is an attempt to offer the names and bibliographic references for taxa of Deltocephalinae (Caribbean, Central America and South America). After each species-group name, the type locality, and anabbreviation of the institution where the type is deposited, are given. The geographical distribution is based upon previously published records. Each species-group name is followed by the informations including of the author (s), publication year and page and when not strictly taxonomical, an abbreviated indication of the matter treated such as: cat. — catalogue, desc. — description, distr. — geographical distribution, ill. — illustration, rev. — revision, syn. — synonymy, tax. — taxonomy.

Four new species of Hisonotus are described from the upper course of the rio Uruguay basin in Brazil: Hisonotus iota from the rio Chapecó drainage; Hisonotus leucophrys from rio Rancho Grande and rio Ariranhas; Hisonotus megaloplax from the rio Passo Fundo drainage; and Hisonotus montanus from the rio Canoas drainage. The species Epactionotus aky, described from the arroyo Yabotí-Guazú drainage in Argentina, is transferred to Hisonotus and rediagnosed. Hisonotus candombe is considered a junior synonym of H. ringueleti. The new taxa, together with H. nigricauda, H. ringueleti, H. charrua, and H. aky represent the genus Hisonotus in the rio Uruguay basin. A taxonomic key for Hisonotus in the rio Uruguay basin is provided. Their distributions are discussed under biogeographic patterns previously proposed for the rio Uruguay basin.
