A New Species

Papagona Ball, 1935 was originally described based on two species from the USA (Arizona). Both species of Papagona (P. papoosa Ball, 1935, type species of genus, and P. succinea Ball, 1935) are redescribed herein based on type specimens, including their previously unknown internal male genitalia. A new species from Brazil (Roraima) is described herein including the male and female terminalia. A taxonomic key to all included species is provided and additional diagnostic characters for this genus are proposed.

The morphological similarities between five new large Argentinomyia species and Talahua fervida Fluke are characterized and presented. Six new species of Argentinomyia (10–12 mm long) are described: Argentinomyia andina Montoya & Wolff, sp. nov. (Colombia), Argentinomyia choachi Montoya, sp. nov. (Colombia), Argentinomyia quimbaya Montoya & Wolff, sp. nov. (Colombia), Argentinomyia huitepecensis Montoya, sp. nov. (México), Argentinomyia puntarena Montoya, sp. nov. (Costa Rica), and Argentinomyia talamanca Thompson, sp. nov. (Costa Rica). The genus Talahua Fluke is re-diagnosed and, Talahua fervida redescribed. A taxonomic key and a comparison of diagnostic characters are presented. Photographs of head, abdominal and wing maculae patterns, as well as illustrations of male genitalia are provided for species identification.

Hard Ticks

AbstractIn many areas of Africa, recent studies highlighted the great impact of ticks on animal and human health throughout the continent. On the other hand, very limited information on the bacterial endosymbionts of the African ticks and their pattern of co-infections with other bacteria are found in literature, notwithstanding their pivotal role in tick survival and vector efficiency. Thus, we investigated the distribution of selected pathogenic and symbiotic bacteria in hard ticks collected from wild, domestic animals and from vegetation in various ecological zones in Africa and their co-occurrence in the same tick host. Overall, 339 hard ticks were morphologically identified as belonging to the genera Amblyomma, Dermacentor, Hyalomma, Haemaphysalis, Ixodes and Rhipicephalus. Molecular screening provided information on pathogens circulation in Africa, detecting spotted fever group rickettsiae, Anaplasma spp., Ehrlichia ruminantium, Borrelia garinii, Babesia spp., Theileria spp. and Coxiella burnetii. Furthermore, our work provides insights on the African scenario of tick-symbiont associations, revealing the presence of Coxiella, Francisella and Midichloria across multiple tick populations. Coxiella endosymbionts were the most prevalent microorganisms, and that with the broadest spectrum of hosts, being detected in 16 tick species. Francisella was highly prevalent among the Hyalomma species tested and correlated negatively with the presence of Coxiella, showing a potential competitive interaction. Interestingly, we detected a positive association of Francisella with Rickettsia in specimens of Hy. rufipes, suggesting a synergistic interaction between them. Finally, Midichloria was the most prevalent symbiont in Rhipicephalus sanguineus sensu lato from Egypt.

Host Relations

Ticks are important ectoparasites and can transmit a wide variety of pathogens to animals and humans worldwide. These ectoparasites are the most important vectors of diseases causing pathogens in domestic and wild animals, and the second for man. In Brazil, Spotted Fever is the only disease transmitted to humans by ticks, while for animals we can highlight babesiosis, ehrlichiosis and anaplasmosis. Although ticks are found in all of Brazil’s biomes, little is known about its diversity and host-relations in the Amazon biome. The existing gaps and the lack of research indicate that the diversity of ticks and their possible pathogens are underestimated in the Brazilian Amazon. Therefore, in order to guide the next studies in the Amazon biome, we present in this chapter a compilation of the records of hard ticks and soft ticks parasitizing wild and domestic animals, and humans. We present the general list of ticks for this biome, their distribution, hosts and importance for public health and veterinary. Finally, the ixodofauna found in the Brazilian Amazon and presented here does not match the vertebrate diversity of this biome, which is one of the largest on the planet. Therefore, more acarologists and epidemiologists are needed in this region.

Formerly Cnemidophorus was thought to be the most speciose genus of Teiidae. This genus comprised four morphological groups that were later defined as four different genera, Ameivula, Aurivela, Cnemidophorus and Contomastix. The last appears as paraphyletic in a recent phylogenetic reconstruction based on morphology, but monophyletic in a reconstruction using molecular characters. Six species are allocated to Contomastix. One of them, C. lacertoides, having an extensive and disjunct geographic distribution in Argentina, Uruguay and Brazil. Preliminary analyses revealed morphological differences among its populations, suggesting that it is actually a complex of species. Here, we describe a new species corresponding to the Argentinian populations hitherto regarded as C. lacertoides, by integrating morphological and molecular evidence. Furthermore, we demonstrate that the presence of notched proximal margin of the tongue is a character that defines the genus Contomastix.

The article discusses main issues of organizing activities for the treatment of stray and street animals in the city of Novosibirsk. The important role of successful solving the problem of stray animals in ensuring environmental comfort and safety of the urban population is noted. Definitions of the concepts “stray animals” and “street animals” are given, the differences between them are emphasized. The main regulatory and legal documents governing the handling of stray and street animals are listed. The ways in which domestic animals get into a stray state are described briefly. The results of the collection and analysis of information on the activities of shelters for stray animals in Novosibirsk are described. The information on the quantitative indicators of the shelters are given. Conclusions on how to solve the problem of stray animals, relying on the latest regulations are drawn.
