摘要

报道了产于西伯利亚南部（俄罗斯）山区的Ch.reshetnikovi sp.nov.（阿尔泰共和国）和Ch.borisi sp.nov..（泰瓦共和国）。Ch.shapkini Mikhailov et Gus'kova，2013年除外，Ch.reshetnikovi sp.nov.有一个略微凸起的身体，上侧呈蓝绿色，鞘翅有规则的刺行和大部分平坦的鞘翅间隔，这将本物种与亚属的所有物种区分开来。来自Ch.shapkini的新物种雄性的主要区别特征是跗节1–3强烈变宽，整个长度上有压痕的肿胀，最后一个腹部胸骨有半圆形凹陷，以及以90°弯曲的aedeagus顶点。borisi Chrysolina sp.nov.有一个凸起的小身体，上侧、股骨和胫骨呈黑色，鞘翅有规则的穿刺行和略微凸起的鞘翅间隔，靠近顶端的耳屏，侧面有一个朝向耳屏基部的狭窄突起。

Two new species of the subgenus Pleurosticha of the genus Chrysolina (Coleoptera: Chrysomelidae) from the mountains of southern Siberia (Altai and Tyva)

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.
