Abstract
Two new species from the subgenus Pleurosticha of the genus Chrysolina are described from the mountains of southern Siberia (Russia): Ch. reshetnikovi sp. nov. (Republic of Altai) and Ch. borisi sp. nov. (Republic of Tyva). Chrysolina reshetnikovi sp. nov. has a slightly convex body, a blue-green coloration of the upper side, regular puncture rows of the elytra and mostly flat elytral intervals, which distinguish this species from all species of the subgenus, except for Ch. shapkini Mikhailov et Gus’kova, 2013. The main distinguishing features of the male of the new species from Ch. shapkini are the strongly broadened tarsomeres 1–3, the pygidium with an impression along its entire length, the last abdominal sternite with a semicircular depression, and the apex of the aedeagus bent at 90°. Chrysolina borisi sp. nov. has a convex small body, black coloration of the upper side, femora and tibiae, regular puncture rows of the elytra and slightly convex elytral intervals, and the aedeagus near the apex with a narrow protrusion of the lateral side directed toward the aedeagus base.
期刊介绍：
Zoosystematica Rossica is an international journal for publication of papers on any aspects of systematic zoology, in all groups of animals, both extant and fossil, from all over the World. The journal is published in English and focuses on the descriptions of new taxa, revisions and reviews, nomenclature, theories and methods of taxonomy and phylogeny, interesting new faunal records, catalogues and checklists, identification keys, phylogenetic relationships and zoogeography. Faunistic articles are published in a limited way and only if they contain new records for large geographical regions and are important for zoogeography or taxonomy.
