Genetics.

We obtained a single barcode from the specimen with CaBOL-ID 1020260 (BOLD: AEP4515). Neither the species nor its congeners are present in BOLD as we provide the first COI sequence.

Remarks.

The records of H. livida in the Caucasus region are known from Julfa and Ordubad (Azerbaijan) (Bey-Bienko 1950), and our records from Georgia extend its known distribution range by almost 680 km to the north-east. Originally described from Cyprus (Brunner von Wattenwyl 1865), the species is also known to occur in Greece (Chopard 1929), Iran, Iraq, Syria, and Turkey (Bey-Bienko 1950; Caesar et al. 2015). Due to the hidden lifestyle of H. livida, little is known about its phenology, and there is no information on its reproductive biology, which is likely somewhat similar to that of other congeners. The general appearance of males and females as well as the somatic characteristics correspond well to the descriptions and drawings by Chopard (1929) and Bey-Bienko (1950). Bey-Bienko also mentions the small differences in coloration between specimens from Parnassus (Greece) and Azerbaijan compared to the conspecifics originating from Asia Minor and Central Asia, with the first ones sometimes being more brightly colored with almost no dark spots on elytra. The juveniles strongly resemble the adult females, but with more prominent ornamentation.
