“…This is in accord with literature reporting Leucocytozoon to be generally rare in the Neotropical region, which might be related to the absence of suitable vectors in lowland areas of South America [ 1 ]. Simuliidae black flies are present in South American tropical lowland areas [e.g., 109 , 110 ], but the local species might not be susceptible to Leucocytozoon spp. [ 111 ] summarised records of Leucocytozoon spp.…”

Background Haemosporidians (Apicomplexa, Protista) are obligate heteroxenous parasites of vertebrates and blood-sucking dipteran insects. Avian haemosporidians comprise more than 250 species traditionally classified into four genera, Plasmodium, Haemoproteus, Leucocytozoon, and Fallisia. However, analyses of the mitochondrial CytB gene revealed a vast variety of lineages not yet linked to morphospecies. This study aimed to analyse and discuss the data of haemosporidian lineages isolated from birds of the family Turdidae, to visualise host and geographic distribution using DNA haplotype networks and to suggest directions for taxonomy research on parasite species. Methods Haemosporidian CytB sequence data from 350 thrushes were analysed for the present study and complemented with CytB data of avian haemosporidians gathered from Genbank and MalAvi database. Maximum Likelihood trees were calculated to identify clades featuring lineages isolated from Turdidae species. For each clade, DNA haplotype networks were calculated and provided with information on host and geographic distribution. Results In species of the Turdidae, this study identified 82 Plasmodium, 37 Haemoproteus, and 119 Leucocytozoon lineages, 68, 28, and 112 of which are mainly found in this host group. Most of these lineages cluster in the clades, which are shown as DNA haplotype networks. The lineages of the Leucocytozoon clades were almost exclusively isolated from thrushes and usually were restricted to one host genus, whereas the Plasmodium and Haemoproteus networks featured multiple lineages also recovered from other passeriform and non-passeriform birds. Conclusion This study represents the first attempt to summarise information on the haemosporidian parasite lineages of a whole bird family. The analyses allowed the identification of numerous groups of related lineages, which have not been linked to morphologically defined species yet, and they revealed several cases in which CytB lineages were probably assigned to the wrong morphospecies. These taxonomic issues are addressed by comparing distributional patterns of the CytB lineages with data from the original species descriptions and further literature. The authors also discuss the availability of sequence data and emphasise that MalAvi database should be considered an extremely valuable addition to GenBank, but not a replacement.

“…Historically, leucocytozoid parasite transmission has been deemed negligible in the Neotropics outside these highland areas, despite the local presence of Simuliidae black flies (Figueiró et al, 2012;Docile et al, 2015;Coscarón and Coscarón-Arias, 2017;Vieira et al, 2017;Menzel et al, 2019), the Diptera insects that transmit these parasites (Valkiūnas, 2005). Early reports using microscopy alone showed low rates of Leucocytozoon infection in Neotropical areas (Galindo and Sousa, 1966;Forrester et al, 1977;White et al, 1978;Bennett and Lopes, 1980;Woodworth-Lynas et al, 1989).…”

The distribution of avian haemosporidians of the genus Leucocytozoon in the Neotropics remains poorly understood. Recent studies confirmed their presence in the region using molecular techniques alone, but evidence for gametocytes and data on putative competent hosts for Leucocytozoon are still lacking outside highland areas. We combined morphological and molecular data to characterize a new Leucocytozoon species infecting a non-migratory red-legged seriema (Cariama cristata), the first report of a competent host for Leucocytozoon in Brazil. Leucocytozoon cariamae n. sp. is distinguished from the Leucocytozoon fringillinarum group by its microgametocytes that are not strongly appressed to the host cell nucleus. The bird studied was coinfected with Haemoproteus pulcher, and we present a Bayesian phylogenetic analysis based on nearly complete mitochondrial genomes of these 2 parasites. Leucocytozoon cariamae n. sp. morphology is consistent with our phylogenetic analysis indicating that it does not share a recent common ancestor with the L. fringillinarum group. Haemoproteus pulcher and Haemoproteus catharti form a monophyletic group with Haemocystidium parasites of Reptilia, supporting the polyphyly of the genus Haemoproteus. We also discussed the hypothesis that H. pulcher and H. catharti may be avian Haemocystidium, highlighting the need to study non-passerine parasites to untangle the systematics of Haemosporida.

“…A ccording to the last catalogue of Neotropical Tabanidae (Fairchild & Burger 1994), 1172 valid species and subspecies have been described from the Neotropical Region of which larvae are known from only 4.1% (Coscarón 2002). In Ecuador, the study of tabanid fl ies began with the description of three Andean species from Quito: Esenbeckia testaceiventris Macquart 1848, Tabanus peruvianus Macquart 1848, and Dasychela ocellus (Walker) 1848.…”

Worldwide information about Tabanidae is biased toward taxonomical research, which has been the main source of diversity data for this group of fl ies. In Ecuador, studies on horse fl ies have been irregular since the fi rst descriptions of three Andean specimens in 1848. Catalogues, checklists and collections in national museums demonstrate that despite its size, Ecuador is at present the richest country in number of tabanids species in the Neotropics after Brazil, Colombia and Mexico, and has one of the highest numbers of species per unit area. The tabanofauna is predominantly shared with Colombia (62.6%), Peru (47%), Brazil (35.9%), Panama (35.4%), and Venezuela (30.3%) that have biogeographic areas in common with Ecuador. Endemism rate of this group is around 12.6%, with Diachlorus, Dicladocera, Esenbeckia, Eristalotabanus (monotypic), and Leucotabanus genera as the most representatives. We add new records of Tabanidae for the country. The genus Hemichrysops was recorded for fi rst time. The number of species in Ecuador now totals 198. A catalogue of all Ecuadorian species is compiled with a localities-gazetteer. We also present and discuss for the fi rst time, the distribution of well known horse fl ies species (Chrysops varians var. tardus, Dicladocera macula and Fidena rhinophora) using georeferenced localities and niche modelling analyses. Résumé. Diversité et modèles de distribution des taons (Diptera : Tabanidae) de l'Equateur. L'information existante sur les Tabanidae à l'échelle mondiale concerne principalement la recherche taxonomique qui a été la source principale de données concernant la diversité de ce groupe de mouches. En Équateur, les études sur les taons ont été irrégulières depuis les premières descriptions en 1848 de trois spécimens des Andes. Les catalogues, listes et collections d'espèces dans les musées nationaux démontrent qu'en dépit de sa taille restreinte, l'Equateur représente actuellement l'un des pays néotropicaux les plus riches en espèces de Tabanidae après le Brésil, la Colombie et le Mexique. L'Equateur abrite l'une des plus fortes densités d'espèces par unité de surface. Sa faune de Tabanidae est partagée principalement avec la Colombie (62,6% d'espèces en commun), le Pérou (47,0%), le Brésil (35,9%), Panama (35,4%) et le Vénézuela (30,3%). Le taux d'endémisme de ce groupe en Equateur est d'environ 12,6%. Les genres Diachlorus, Dicladocera, Esenbeckia, Eristalotabanus (monotypique) et Leucotabanus sont les plus représentatifs. Dans cette étude, nous présentons de nouveaux données de Tabanidae pour le pays (dont le genre Hemichrysops observé pour la première fois), menant ainsi à une liste de 198 espèces pour le pays. Un catalogue de toutes les espèces équatoriennes est annexé avec toutes les localités. Pour la première fois pour ces insectes, nous présentons et discutons également la distribution de certaines espèces bien connues (Chrysops varians var. tardus, Dicladocera macula et Fidena rhinophora) à l'aide de localités géoréférencées et de modèles de niche.
