Ticks are important vectors of emerging health problems in humans and animals. We conducted several field surveillances to investigate the fauna of hard ticks on domestic animals in seven governorates of Egypt during 2018–2019. A total of 3265 individual tick specimens were collected and identified to the species level; the specimens belong to 11 species within three genera ( Amblyomma , Hyalomma , and Rhipicephalus ). Tick infestation was highest in dromedary camels (70%), followed by dogs (52.5%), cattle (50%), buffaloes (38%), and horses (12%). Ten species were collected from dromedary camels, 2 from cattle, and one species from dogs, buffaloes, and horses. Diagnostic characters with high‐quality photographic images of the 11 tick species were provided. New measurements of the body regions such as spiracles and body grooves were also obtained to provide further details on morphological variations among the diverse tick species. This study provided detailed descriptions of the genital apertures of five Hyalomma species. Morphological variations of male Hyalomma impeltatum , and genital apertures of female Hyalomma dromedarii and Hyalomma excavatum were also examined in this study. Finally, we provided additional details on local geographic distributions, hosts, endemicity status, and disease relationships of the eleven tick species.
