Specimen Identification

DNA barcoding is helping in discovering high levels of cryptic species and an underestimation of biodiversity in many groups of organisms. Although mammals are arguably the most studied and one of the least speciose taxonomic classes, the rate of species discovery is increasing and biased for small mammals on islands. An earlier study found bats in the Caribbean as a taxonomic and geographic deficiency in the International Barcode of Life initiative to establish a genetic reference database to enable specimen identification to species. Recent surveys in Dominican Republic, Jamaica, and Martinique have documented and barcoded half of the 58 bat species known from the Caribbean. I analyze all available barcode data of Caribbean bats to investigate biogeography and cryptic species in the Neotropical region. Analysis of the mitochondrial DNA gene cytochrome c oxidase subunit 1 results in a phylogenetic tree with all but one species as well-supported and reciprocally monophyletic. With a broader sampling across the Neotropics, there are also divergent lineages that exhibit biogeographic structuring: (i) a phylogenetic split between northern and southern Dominican Republic in three species, (ii) two taxa with cryptic species associated with higher degree of island endemism, (iii) populations of two widely distributed species with deep divergence between the Caribbean and North and Central America, and (iv) one species in the Caribbean with affinities to taxa in South America.

The Neotropical species of the genus Manota Williston are studied, based on material of 146 specimens from French Guiana, Ecuador, Nicaragua, Dominica and the Dominican Republic. Four new species are described, viz. M. corniculata sp. n. (French Guiana), M. pseudocavata sp. n. (French Guiana), M. truuverki sp. n. (French Guiana) and M. vladi sp. n. (Dominican Republic). Manota defecta Williston, 1896, the type species of the genus, is listed from Dominica, representing the first record since its description more than a century ago from a Southern Caribbean Island, St. Vincent. New records of 13 additional species are provided: M. acutistylus Jaschhof & Hippa, 2005 (Dominica), M. aligera Hippa, Kurina & Sääksjärvi, 2017 (French Guiana), M. digitata Hippa, Kurina & Sääksjärvi, 2017 (French Guiana), M. iota Hippa & Kurina, 2013 (French Guiana), M. micula Hippa & Kurina, 2013 (French Guiana), M. nordestina Kurina, Hippa & Amorim, 2018 (French Guiana), M. parva Jaschhof & Hippa, 2005 (Nicaragua), M. pauloides Hippa, Kurina & Sääksjärvi, 2017 (Ecuador), M. perplexa Kurina, Hippa & Amorim, 2017 (Nicaragua), M. rotundistylus Jaschhof & Hippa, 2005 (Ecuador), M. serrulata Hippa, Kurina & Sääksjärvi, 2017 (French Guiana), M. spinosa Jaschhof & Hippa, 2005 (French Guiana), M. subaristata Kurina, Hippa & Amorim, 2017 (Ecuador). The number of Neotropical Manota species has risen to 96.

Background:Spondyloarthritis (SpA) is a group of interrelated disorders: axial spondyloarthritis (Ankylosing Spondylitis [AS] /Non Radiographic Axial Spondyloarthritis [Nr-AxSpA]), psoriatic arthritis (PsA), reactive arthritis (ReA), inflammatory bowel disease-associated arthritis (IBD), and undifferentiated SpA (USpA).1Objectives:The objectives of this study were: a) to examine the epidemiology, disease subsets, and clinical characteristics of patients with SpA in Central America and the Caribbean region; and b) to describe the natural history of these conditions in their acute and chronic forms, to determine clinical sub-types and severity.Methods:PRECAES is a cross-sectional observational study, including patients from private rheumatology clinics in three Central American countries (Guatemala, Honduras and Panama) and one in the Caribbean (Dominican Republic).Patients were enrolled between April 25th, 2018 and July 31st, 2019. Inclusion criteria: SpA diagnosis fulfilling ASAS classification criteria, age 18 - 45 years, sign informed consent and willing to perform protocol procedures during a single visit. Exclusions: any other rheumatic diseases, malignancy or HIV.Results:Each center identified 50 consecutive patients with SpA. The main reason for exclusion from this analysis was not meeting the age requirement (N=94). Therefore, we analyzed 25 from Dominican Republic (DR), 25 from Guatemala, 32 from Honduras and 24 from Panama.When applying ASAS axial and peripheral SpA definitions, all countries had high number of AS Patients. Subclinical classification by country showed the most frequent diagnosis was AS (64.1%), followed by PsA (16%), ReA (9.4%), Undifferentiated SpA (7.5%), IBD associated arthritis (1.9%) and Nr-AxSpA (0.9%) (p<0.001); characteristics of patient population and sub-clinical classification by country, Table 1. When clinical manifestations were classified as axial or peripheral SpA, 70.7% were axial in the four countries.Table 1.Patient population characteristics and Sub-clinical classification by CountrySD or ± = Standard DeviationUndifferentiated SpA (USpA), Reactive Arthritis (ReA), Nonradiographic Axial SpA (Nr-AxSpa), (AS), Inflammatory Bowel Disease-Associated Arthritis (IBD), Psoriatic Arthritis (PsA)Time from onset symptoms to diagnosis ranged in years, from 3.15 (Guatemala) to 8.2 (Honduras), among the four countries. BASMI scores were higher in Honduras (mean 5.15) and lowest in Panama (mean 1.61). Of note, the time from symptom onset to diagnosis was also longest in Honduras.NSAIDs and DMARDs were used in most countries. Glucocorticoids were rarely used in this population. Biologics are mainly used in Panama (16%), and Honduras (11%); only 8% of the enrolled patients in Dominican Republic and 2% in Guatemala.Conclusion:The most prevalent SpA diagnosis in the region is Ankylosing Spondylitis. Patient diagnosis is delayed up to 8.2 years and only 2 to 16% of the patients receive a proper treatment with a biologic therapy.This data invites to further investigation and brings opportunity to improve patients care.References:[1]Rudwaleit, M. et al.

Different Parts

Of the 65 species of Campylopus known from tropical America, 33 are andine in distribution, 16 are found only in SE Brazil, 8 have wide ranges through Central and South America, 3 species are disjunct in SE-North America and Brazil, 3 are confined to the Caribbean and one species belongs to the circum-pacific and one to the tethyan element. For different parts of the Neotropics, the composition of phytogeographical elements is calculated. For the first time, bryophyte distributions are compared to the Pleistocene forest refuges proposed by zoologist and phanerogamists. The distribution of several rainforest species of Campylopus coincides with the major part of the montane refugia. Using an interpretation of the present-day ranges, a hypothetical survey is given of the origin and evolution of this genus in tropical South and Central America. The ranges of part of the species can be explained only by long distance dispersal, while the ranges of other species seem to be relictual.

Specimen Identification

The use of COI barcodes for specimen identification and species discovery has been a useful molecular approach for the study of Anura. Here, we establish a comprehensive amphibian barcode reference database in a central area of South America, in particular for specimens collected in Mato Grosso do Sul state (Brazil), and to evaluate the applicability of the COI gene for species-level identification. Both distance- and tree-based methods were applied for assessing species boundaries and the accuracy of specimen identification was evaluated. A total of 204 mitochondrial COI barcode sequences were evaluated from 22 genera and 59 species (19 newly barcoded species). Our results indicate that morphological and molecular identifications converge for most species, however, some species may present cryptic species due to high intraspecific variation, and there is a high efficiency of specimen identification. Thus, we show that COI sequencing can be used to identify anuran species present in this region.

The cleptoparasitic bee genus Epeolus Latreille, 1802 is for the first time reviewed for species occurring in the Caribbean, Central America and Mexico, and a single dichotomous identification key to the females and males of species present or likely to be present in these regions is presented. A total of 25 species have been confirmed as present across the region, although another 10 likely occur south of the Mexico–United States border. Three species are newly described—E. hanusiae sp. nov., E. nomadiformis sp. nov. and E. odyneroides sp. nov.—and redescriptions are provided for species occurring exclusively south of the United States of America (species occurring north of Mexico were recently revised elsewhere) except E. danieli (Genaro, 2014) comb. nov., which was recently described. One subspecies is elevated to species level (E. obscuripes Cockerell, 1917 stat. nov.). The following five names are newly synonymized under those of four valid species: Trophocleptria schraderi Michener, 1954 syn. nov. under E. boliviensis Friese, 1908, Tro. odontothorax Michener, 1954 syn. nov. under E. claripennis Friese, 1908, E. rugosus Cockerell, 1949 syn. nov. and E. xanthurus Cockerell, 1917 syn. nov. under E. luteipennis Friese, 1916, and E. schmidti Friese, 1925 syn. nov. under E. obscuripes. A diagnosis is provided for the presumably monophyletic and almost entirely Neotropical species group originally regarded as a separate genus, Trophocleptria Holmberg, 1886. Differential diagnoses accompany the descriptions / redescriptions of Neotropical species of Epeolus, and known collection records and information about their ecology are presented.

The described Neotropical species of the common and speciose fairyfly genus Gonatocerus Nees ab Esenbeck (Hymenoptera: Mymaridae) are reviewed and re-diagnosed. Eighty-four valid species are recognized including 11 newly described ones. Illustrated identification keys are provided to identify the 5 subgenera recognized in Gonatocerus and to females of each subgenus. The keys include 79 of the treated species, the other five species are known from males only. The known distribution ranges of the species, including new records of extralimital specimens examined, are given. Host associations of the treated species are also given, with emphasis on those species that parasitize eggs of proconiine sharpshooters (Hemiptera: Cicadellidae: Cicadellinae: Proconiini), all of which belong to the ater and morrilli subgroups of the ater species group of G. (Cosmocomoidea Howard), stat. rev. The other four recognized subgenera within Gonatocerus are the nominate subgenus, G. (Gonatocerus) (= sulphuripes species group of authors), G. (Lymaenon Walker), stat. rev. (= litoralis and straeleni species groups of authors), G. (Gastrogonatocerus Ogloblin), stat. rev. (= membraciphagus species group of authors), and G. (Gahanopsis Ogloblin), syn. n. & stat. n. (= deficiens species group of authors). Newly treated as synonyms of G. (Lymaenon) are Rachistus Foerster, Oophilus Enock, Agonatocerus Girault, Gonatoceroides Girault, and Decarthrius Debauche, all syn. n. Two species groups are recognized within G. (Cosmocomoidea) in the New World: the ater group, to which most Neotropical species belong (with the ater, bucculentus, morrilli, and the newly defined chusqueicolus subgroups) and the masneri group, with two described species from the Dominican Republic. The 11 new species described are G. (Gahanopsis) arkadak Triapitsyn sp. n. (Colombia), G. (Cosmocomoidea) barbos Triapitsyn sp. n. (Costa Rica and Mexico), G. (Cosmocomoidea) blefuscu Triapitsyn sp. n. (Costa Rica), G. (Cosmocomoidea) cuscus Triapitsyn sp. n. (Peru), G. (Cosmocomoidea) garchamp Triapitsyn sp. n. (Argentina), G. (Cos- mocomoidea) gerasim Triapitsyn sp. n. (Mexico), G. (Cosmocomoidea) hispaniolus Triapitsyn & Huber sp. n. (Dominican Republic), G. (Cosmocomoidea) kiskis Triapitsyn sp. n. (Argentina), G. (Cosmocomoidea) logarzoi Triapitsyn sp. n. (Argentina), G. (Cosmocomoidea) mumu Triapitsyn sp. n. (Argentina), and G. (Cosmocomoidea) rakitovi Triapitsyn sp. n. (Costa Rica). Seven new synonymies are proposed: Gonatocerus h-luteum (Ogloblin) syn. n. under G. (Cosmoco- moidea) nigriflagellum (Girault); G. enicmophilus Huber syn. n. and G. necator (Ogloblin) syn. n. under G. (Cosmoco- moidea) bonariensis (Brèthes); G. dimorphus (Ogloblin) syn. n. and G. monrosi (Ogloblin) syn. n. under G. (Gastrogonatocerus) margiscutum Girault; and G. setulosus (Ogloblin) syn. n. and G. dorsiniger (Ogloblin) syn. n. under G. (Gastrogonatocerus) membraciphagus Ogloblin. Litus maculipennis Ashmead, Gahanopsis deficiens (Ogloblin), and Gahanopsis straeleni (Debauche) are transferred to Gonatocerus as, respectively, G. (Cosmocomoidea) maculipennis (Ashmead) comb. n., G. (Gahanopsis) deficiens (Ogloblin) comb. n., and G. (Lymaenon) straeleni (Debauche) comb. n. Lectotypes are designated for the following 23 species: G. (Gahanopsis) acanophorae (Ogloblin), G. (Gahanopsis) aethalionis (Ogloblin), G. (Cosmocomoidea) annulicornis (Ogloblin), G. (Gastrogonatocerus) anomocerus Crawford, G. (Gonatocerus) appendiculatus (Ogloblin), G. (Gonatocerus) bonaerensis (Ogloblin), G. (Cosmocomoidea) caudatus (Ogloblin), G.

Ten cases of chikungunya were diagnosed in Spanish travellers returning from Haiti (n=2), the Dominican Republic (n=7) or from both countries (n=1) between April and June 2014. These cases remind clinicians to consider chikungunya in European travellers presenting with febrile illness and arthralgia, who are returning from the Caribbean region and Central America, particularly from Haiti and the Dominican Republic. The presence of Aedes albopictus together with viraemic patients could potentially lead to autochthonous transmission of chikungunya virus in southern Europe.

This book is an extended argument about the “coloniality” of power. In a shrinking world where sharp dichotomies, such as East/West and developing/developed, blur and shift, this book points to the inadequacy of current practices in the social sciences and area studies. It explores the crucial notion of “colonial difference” in the study of the modern colonial world and traces the emergence of an epistemic shift, which the book calls “border thinking.” Further, the book expands the horizons of those debates already under way in postcolonial studies of Asia and Africa by dwelling on the genealogy of thoughts of South/Central America, the Caribbean, and Latino/as in the United States. The book's concept of “border gnosis,” or sensing and knowing by dwelling in imperial/colonial borderlands, counters the tendency of occidentalist perspectives to manage, and thus limit, understanding. A new preface discusses this book as a dialogue with Hegel's Philosophy of History.
