The purpose of this paper is to document the males of Leioproctus rosellae Gonzalez in Gonzalez & Florez, 2011 (Colletidae, Paracolletini) and Heriades tayrona Gonzalez & Griswold, 2011 (Megachilidae, Osmiini), two solitary bee species recently described based on females from the Caribbean coast of Colombia. Leioproctus rosellae is currently known only from the holotype, while H. tayrona is known from a few specimens from the type locality. The discovery of these species in northern Colombia considerably extended the distribution of Leioproctus Smith (sensu Michener, 2007) and Heriades Spinola in the Western Hemisphere. In the Americas, Leioproctus was known from Chile and Argentina to central Peru and northeastern Brazil, while Heriades was known from southern Canada to Panama and the Greater Antilles (Michener 2007). The discovery of H. tayrona also represented the first record of the tribe Osmiini for South America.

The male terminalia of a non-type Diathoneura longipennis (Malloch 1926) specimen,collected in Peru, were dissected and analyzed. The aedeagus and associated sclerites were found tohave been fixed at a late stage of protrusion, resulting in a different morphology, when compared to thetwo previous publications, which were fixed at earlier stages. Consequently, additional details of certainanatomical parts were observed and a better understanding of the aedeagus protruding process was attained.Diathoneura longipennis has been previously identified in San Mateo, Alajuela, Costa Rica (type locality)and Panama, and this specimen represents the first record of this species in South America.

A New Species

Acanthemblemaria aceroi new species is described from the upwelling region of the Caribbean coasts of Venezuela and Colombia. It differs from its closest relative, Acanthemblemaria rivasi Stephens, 1970, known from Panama and Costa Rica, in the posterior extent of the infraorbitals, details of head spination, and unique COI sequences. The description of Acanthemblemaria johnsonsi Almany & Baldwin, 1996, heretofore known only from Tobago, is expanded based on specimens from islands offshore of eastern Venezuela.

Capsicum chinense is commercially the most important pepper species grown in the Caribbean. It is popularly used to impart pungency and flavor to Caribbean cuisine. However, unlike Capsicum annuum, which is the most commercially exploited domesticated species internationally, C. chinense has not been methodically collected or characterized for systematic improvement through plant breeding. The objectives of the study were to assess the diversity of C. chinense and its structure within the Caribbean basin and to determine its phylogenetic relationship to groups within South America. DNA isolated from 201 accessions of C. chinense, representing geographical regions where the species is found, were amplified using arbitrary primers to generate 138 polymorphic and reproducible random amplification of polymorphic DNA (RAPD) markers. Nei’s and Shannon’s diversity indices for C. chinense (0.28 and 0.419, respectively) were higher in South America compared with Central America or the Caribbean, corresponding to its putative center of diversity. The study showed the existence of three phylogenetic clusters within C. chinense. The largest cluster consisted of accessions from the Upper Amazon region, the Guianas including Venezuela, and the Lesser Antilles of the Caribbean. The other major cluster was represented by accessions principally from the Lower Amazon region. Another distinct but small cluster consisted of samples solely from the Greater Antilles of the Caribbean. The discovery of the three phylogenetic clusters within C. chinense may have potential for exploiting heterosis in breeding. The implications of the findings to the understanding of the phylogenetic origin and distribution of C. chinense are discussed.

Soybean rust (Phakopsora pachyrhizi Sydow) has been known to occur in eastern Asia and Aus-tralia for decades. In recent years, the disease entered Africa and South America and has spread rapidly in these continents. It has become a concern to the U.S. soybean industry. To assess the threat of soybean rust, we used a modeling approach to determine the potential geographical zones where the fungus might overwinter and serve as source areas for seasonal epidemics. Long-term meteorological averages were used to assess the temperature stresses by using CLIMEX, and the dry stress with an algorithm developed in this study. Integration of stresses was used to predict the likelihood of survival of the rust in a defined location. Our results suggest that the new soybean rust invasions in Africa and South America occurred in the areas where the fungus might persist year-round. The main regions where rust has not been reported but might overwinter are located in the western hemisphere, including northern South America, Central America, the Caribbean, Mexico, southern Texas, and Florida. Southeastern China and neighboring areas are suggested as the primary regions where initial spores for soybean rust epidemics in central China are produced. If the disease is to establish in the United States, it is likely to be restricted to parts of Florida and southern Texas during the winter in the frost-free areas or areas where the fungus could overcome short periods of below-freezing temperatures. Occurrence of rust epidemics within the U.S. soybean belt would depend on south-to-north dispersal of uredospores.

Included is a list of the 26 clinid species known from the Colombian Caribbean. Labrisomus sp., L. albigenys, L. bucciferus, Starksia atlantica, Acanthemblemaria rwasi, Coralliozetus sp., Ekemblemaria nigra, Emblemariopsis sp. and Enneanectes sp., are new reports from the northern Caribbean coast of South America. Malacoctenus macropus and Stathmonotus stahli (subespecies tekla) are new reports from the Colombian Caribbean. The richness of species of clinid fishes of the southern Caribbean is demostrated since there are 49 species known, of which 13 are supposed to be exclusive to this zone. This restricted zoogeographical distribution is clearly shown for the chaenopsids, since one fourth of the Caribbean species are known only from the south. The genera Ekemblemaria, Coralliozetus and Protemblemaria have been speciated principally in the American Pacific and in the Caribbean next to the Isthmus of Panama.

The Pipidae family is represented by seven frog species in South America and Panama, strictly linked to aquatic environments. Pipa carvalhoi is currently distributed in the states of Bahia, Ceará, Espírito Santo, Minas Gerais, Paraíba and Pernambuco, in Brazil. We report the first record of Pipa carvalhoi for the state of Sergipe, Brazil, in the Conservation Unity Monumento Natural Grota do Angico, Poço Redondo municipality. This study significantly expands the distribution of the species in northeastern Brazil.

During research in the Tirimbina Biological Reserve, on the Caribbean slope of Costa Rica, we captured adult specimens and reared larvae of the dragonfly Elga leptostyla Ris, 1911, which belongs to the Libellulidae. This species was previously reported only from southern Panama to northern South America. Therefore, this is the first record of the species and genus from Costa Rica, increasing the number of Libellulidae species recorded in the country to 95. This species’ known distribution is northwards.

Notidobiella amazoniana Holzenthal & Blahnik, 2010 was known only from the type locality in Amazonas state, Brazil. Herein, we provide the first record of N. amazoniana for Roraima state, thus extending the geographic range of this species to the northernmost state of Brazil. Its occurrence in Roraima also represents the first record of the family Sericostomatidae for the state and the most northern record of the genus in South America. Information on the holotype of N. amazoniana and a distribution map for all species of Notidobiella are provided.
