Abstract
We present a field-collected Hyalomma anatolicum gynandromorph in Xinjiang, China. Compared to the normal H. anatolicum, the gynandromorphic tick was a typical bipartite protogynander: half of the tick body displayed normal female traits, whereas the other side showed normal male traits. The engorged gynandromorphic tick laid hundreds of eggs, and the eggs looked normal.

Abstract
The present study reports anomalies in Hyalomma dromedarii and Hyalomma rufipes adults collected from dromedary camels (Camelus dromedarius) in Aswan, Egypt, between January and June 2022. A total of 52 adult ticks displayed one or several local and/or general anomalies. A wide variety of local anomalies was observed including atrophy of one or multiple legs, ectromely, absence of accessory adanal and subanal plates, fusion of adanal and accessory plates, and presence of sclerotized formation in the ventral plate, as well as abnormalities of the spiracle, anal groove, festoon, parma, and posteromedian groove. General anomalies comprised of asymmetries and gynandromorphism. Local anomalies were documented among H. dromedarii and H. rufipes, whereas general anomalies were documented only from H. dromedarii. The present work represents the first report of deuterogynander intrigue gynandromorphism in H. dromedarii, as well as the first report of morphological abnormalities in H. dromedarii and H. rufipes from Egypt.

Abstract
Rhipicephalus haemaphysaloides is endemic in South and Southeast Asia, and it is known to parasitise domestic animals such as cattle, horses, sheep, and dogs. Despite infestation on multiple hosts, little attention has been paid to its morphological and molecular variation. The present study describes local morphological abnormalities for the first time in R. haemaphysaloides from Malaysia, and highlights the presence of three cytochrome c oxidase subunit I (COI) operational taxonomic units with 0.46-9.81% distances within the so-called R. haemaphysaloides in Malaysia, Thailand, and Pakistan.

Rhipicephalus sanguineus Complex in the Americas: Systematic, Genetic Diversity, and Geographic Insights. Pathogens 2021; 10:pathogens10091118. [PMID: 34578151 PMCID: PMC8471700 DOI: 10.3390/pathogens10091118] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 08/24/2021] [Accepted: 08/28/2021] [Indexed: 11/23/2022] Open
Abstract
The Rhipicephalus sanguineus group encompasses at least 12 validated species of Palearctic and Afrotropical hard ticks, which are relevant in veterinary medicine and public health. The taxonomy of R. sanguineus s.s., has been particularly intensely debated, due to its wide geographic distribution, morphological variants, parasite-host associations, and its capacity and vectorial competence for the transmission of several pathogens. By sequencing mitochondrial markers, it was possible to identify the existence of multiple lineages, among which the Tropical and the Temperate lineages stand out, particularly in America. However, the northern limit between these lineages is not clear due to the lack of extensive sampling across Mexico. For this reason, the aim of the present study was to determine the genetic diversity and structure of the R. sanguineus group in Mexico and to compare it with the populations reported in the Americas, in order to propose the northern limit of the R. sanguineus Tropical lineage and the potential regions of sympatry with R. sanguineus s.s. The findings of this study now confirm the presence of R. sanguineus s.s. in Mexico, showing a subtle genetic structure and high genetic diversity throughout its distribution in the Americas. In contrast, the Tropical lineage seems to be genetically less diverse in its overall distribution in the Americas. The genetic diversity of these two independent lineages could have important epidemiological implications in the transmission of tick pathogens.

Abstract
The present report describes morphological anomalies in Rhipicephalus sanguineus s.s. collected from dogs between February 2017 and May 2019 in the steppic region of Djelfa and high plateau area of Bordj-Bou-Arreridj in Algeria. Out of 1043 ticks from 147 infested dogs, four adult ticks (0.38%), collected from four dogs, exhibited local morphological abnormalities. One male displayed ectromely of leg I left, and the other three specimens exhibited multiple associated anomalies in idiosomas and exoskeletons, festoons, stigmas (spiracles), as well as in adanal and accessory plates. This report provides additional exemplars of morphological abnormalities in tick populations of Africa, particularly North Africa.
