Ecology and other information.

Ixodes laguri is a tick species which is mainly a nidicolous parasite of rodents and small and medium carnivores, first of all ground squirrels. It is present usually in zonal and mountainous steppes at the altitude of 1500 m a. s. l. This tick species is less common in desert and semi-desert biotopes ( Filippova 1977).

Filippova (1977) states that the tick has four subspecies – I. laguri laguri , I. l. armeniacus, I. l. colchicus and I. l. slovacicus. The differential characters of the female and the male of I. l. slovacicus are based on comparison with characters of the other subspecies in Pomerantsev (1950) but some of them, such as the genital aperture and chaetotaxy of the scutum and the hypostome and the coxa 1, are not characterized precisely enough ( Filippova 1977).

According to Filippova (1977), I. laguri laguri can be found in Moldova, Ukraine, Kazakhstan, as well as in the south of Russia; I. l. armeniacus is distributed in the Caucasus – North Osetia-Alania, Dagestan, Georgia, Armenia and Azerbaijan; I. l. colchicus is known from the western spurs of the Greater Caucasus, the now abandoned rural locality Babuk-Aul; I. l. slovacicus was described from the south-east of Slovakia.

The type specimens of I. laguri are deposited at the Zoological Institute of the Russian Academy of Sciences and include I. l. armeniacus: the lectotype, female; Armenia, Nalband, from Mesocricetus brandti Nehr. , 9. 9. 1936; AL I 558 and the paralectotype, male; AL I 556, description – Filippova 1977: 384 (female, male, nymph; larva unknown). ( Filippova 2008), as well as I. l. colchicus : the lectotype, male; Western Caucasus, near Babuk-Aul, Glis glis L., 30. 9. 1935, coll. V. K. Popov, det. В. Pomerantsev: I. l. colchicus , type; AL I 554 a; paralectotypes: 2 females; AL I 554 a, description – Filippova 1977: 384 (female, male; nymph and larva unknown) ( Filippova 2008).
