    Abstract Ticks identified as Rhipicephalus sanguineus (Latreille, 1806) have been recorded in Australia since 1896. It is now recognized that ticks identified as R. sanguineus belong to different lineages. Recently, the so‐called temperate lineage has been redescribed as R. sanguineus sensu stricto with a designated neotype. In Australia, the evidence suggests that only R. sanguineus sensu lato tropical lineage exists. We present a genetic evaluation of R. sanguineus sensu Roberts (1965) from museum material that was evaluated or identified by Roberts. We evaluated 12 museum specimens collected between 1913 and 1964, from various locations around Australia at the molecular level. DNA isolation was successful for 4/12 specimens. All four museum specimens were 100% identical to each other and to the reference R. sanguineus s.l. tropical lineage. Measurements of morphologically significant structures for male and female museum and contemporary tick specimens were obtained. The morphologically significant structures revealed there was no significant difference (ANOVA, P > 0.05) between these groups of male and female ticks. This study updates and supplement the comprehensive descriptions provided by Roberts (1965), which genetically belong to R. sanguineus s.l. tropical lineage.

    A systematic study has been carried out on hard ticks from Ankara Province, Turkey. Between April 2010 and July 2012, 1800 tick specimens belonging to 9 species were identified at 31 locations in 9 districts. Tick species are listed as follows: Rhipicephalus sanguineus group (43.44%), Rhipicephalus bursa (36.67%), Hyalomma marginatum (8.83%), Haemaphysalis parva (6%), Hyalomma aegyptium (2.39%), Hyalomma excavatum (1.33%), Dermacentor marginatus (1.06%), Haemaphysalis punctata (0.22%), and Hyalomma detritum (0.06%). Ticks were collected from host animals and from vegetation via the flagging method. The species of the genus Rhipicephalus were present in most of the study areas, the most common being the Rhipicephalus sanguineus group (20/31). Hyalomma species were mostly collected from host animals, with Hyalomma marginatum being the most common species in this genus (8.83%). We also observed seasonal variations in abundance, with the highest number in May. The district with the most abundant ticks was determined to be Kızılcahamam, which had the highest tick abundance rate of 28.6%.
