We show how combination of chromosomal and molecular markers can be applied for proper species identification in Agrodiaetus Hübner, 1822 blue butterflies. Using this approach we provide first evidence for presence of P. (A.) poseidon (Herrich-Schäffer, [1851]) in Georgia.

The blue butterfly subgenus Agrodiaetus Hübner, 1822 belongs to the genus Polyommatus Latreille, 1804 (
Here we show how combination of chromosomal and molecular markers can be applied for proper species identification in Agrodiaetus. Using this approach we provide first evidence for presence of P. (A.) poseidon (Herrich-Schäffer, [1851]) in Georgia.
The samples used for molecular and chromosomal analysis were collected in Georgia (Akhaltsikhe, 41.60N, 43.06E, 1000 m alt., 18 July 2014, V. Lukhtanov et V. Tikhonov leg., samples 2014VL56, 2014VL57, 2014VL58, 2014VL62, 2014VL63, 2014VL64, 2014VL65, 2014VL68, 2014VL69, 2014VL70). The methods of DNA sequencing, chromosomal analysis and phylogenetic inference were described previously (
The species P. (A.) poseidon (= Lycaena poseidon var. mesopotamica Staudinger, 1892, synonymized with P. poseidon by Schurian et. 1992) is known to be an endemic of the Middle East sporadically distributed from Kütahya in West Turkey to Artvin in North-East Turkey (
The taxon P. (A.) deebi (Larsen, 1974) discovered in Lebanon and Syria is often considered as a subspecies of P. (A.) poseidon (e.g.
Males of P. (A.) poseidon have plesiomorphic (
A population of blue butterflies which were morphologically similar to P. (A.) poseidon (Fig.

Bayesian tree of the species close to Polyommatus (Agrodiaetus) poseidon inferred from COI sequences. Posterior probability values >50% are shown.
The haploid chromosome number n=19 was found in MI and MII cells of three studied individuals (2014VL57, 2014VL58, 2014VL62) (Fig.

Thus, although in the studied case neither the DNA barcodes nor chromosomal numbers are species-specific characters, their combination clearly indicates that the population from Akhaltsikhe should be identified as P. (A.) poseidon. This is the first evidence of P. (A.) poseidon for Georgia and for Caucasus region at whole.
