Microscopic anatomy of the Haller’s organ of snake ticks

Ticks (Acari: Ixodidae) of three Timor-Leste reptiles: first country record of Amblyomma helvolum, with new interactions and an updated list of host species

“…Ghosh et al (2018) described and illustrated the ticks retrieved from the two snakes as without eyes and Coxa I with internal and external spurs almost equal in size (eyes present, Coxa I with external spur about twice as long as the internal spur in A. helvolum; Anastos, 1950;Robinson, 1926;Voltzit and Keirans, 2002). We therefore follow Guglielmone et al (2015) and consider the records of A. helvolum by Ghosh et al (2017Ghosh et al ( , 2021 as unconfirmed, since it seems that the authors of those reports used the same characteristics as adopted by Ghosh et al (2018), and they are most likely of a type of tick that is not conspecific with A. helvolum. The remaining records of A. helvolum from West Bengal (India) are all from captive hosts (Table 2), and the presence of natural populations of this tick species in West Bengal remains to be confirmed.…”

New host records of the reptile tick Amblyomma helvolum Koch (Ixodida: Ixodidae: Amblyomminae) in Taiwan

“…Amblyomma helvolum is a polyxenous bont tick primarily associated with squamates, particularly snakes, skinks, and varanid lizards. Many reptile species have been reported as hosts of A. helvolum , including representatives of the genera Boiga (Mao et al 2019), Bungarus (Ghosh et al 2021), Carlia (Oda et al 2022), Coelognathus (Sharif 1928; Audy et al 1960; Tanskul et al 1973; Oda et al 2022), Dasia (Auffenberg 1988), Dendrelaphis (Keirans 1984), Elaphe (Chao et al 2013), Eryx (Ghosh et al 2021), Eutropis (Krijgsman & Ponto 1931; Kohls 1950; Audy et al 1960; Kho et al 2019), Fowlea (Sumrandee et al 2014a, b; Sumrandee et al 2015; Kaenkan et al 2020), Gonocephalus (Auffenberg 1988), Gonyosoma (Keirans 1984), Hydrosaurus (Kohls 1950), Lycodon (Tabug & Necesito 2021), Malayopython (Neumann 1901; Schulze 1933; Kohls 1950; Audy et al 1960; Hoogstraal et al 1968; Tansku et al 1983; Kim 2020), Naja (Anastos 1950; Kohls 1957; Audy et al 1960; Kho et al 2015; Ghosh et al 2021), Ophiophagus (Warburton 1926), Otosaurus (Auffenberg 1988), Ptyas (Audy et al 1960; Lazell et al 1991; Sumrandee et al 2014a, b; Sumrandee et al 2015; Kaenkan et al 2020), Python (Sumrandee et al 2014a,b; Sumrandee et al 2015; Ghosh et al 2021), Rhabdophis (Audy et al 1960), Tropidophorus (Auffenberg 1988), Varanus (Neumann 1910; Sharif 1928; Schulze 1933; Kohls 1950; Audy et al 1960; Parrish 1971; Tanskul et al 1983; Keirans 1984; Auffenberg 1988; King & Green 1999; Pianka et al 2004; Kaenkan et al 2020), and Xenochropis (Audy et al 1960) . In addition, A. helvolum has been reported from the freshwater turtle genus Heosemys (family Geoemydidae) (<...…”

Studies on the surface ultrastructure of a snake tick, Amblyomma helvolum (Acari: Ixodidae)

“…SEM study of a snake associated tick, A. gervaisi from natural habitat was undertaken (Ghosh and Misra 2012), where sexual dimorphism of A. gervaisi was established. Later, Ghosh et al (2017) provided a detail microscopic anatomy of the Haller's organ of A. gervaisi and A. helvolum by using SEM and TEM.…”
