摘要

催吐利莫德罗姆斯。n.（鞘翅目：Carabidae）是从波罗的海琥珀（始新世）中描述和说明的。根据其形态特征，该新种被认为是现存全北极无翅目物种群的姐妹分类单元。此外，这里描述的标本可能代表了一种由压力引发的反流，这将代表甲虫这种过程的第一个化石记录。

A new fossil species of the genus Limodromus Motschulsky, 1850 (Coleoptera: Carabidae: Platynini) from Baltic amber with remarks on its death process

Limodromus emetikos sp. n. (Coleoptera: Carabidae) is described and illustrated from Baltic amber (Eocene). Based on its morphological features, the new species is considered a sister taxon of the extant Holarctic assimilis species group. Furthermore, the specimen described here could represent a case of stress-triggered regurgitation, which would represent the first fossil record of such a process in beetles.

期刊介绍： Insect Systematics & Evolution (ISE) publishes original papers on all aspects of systematic entomology and the evolutionary history of both extant and extinct insects and related groups. Priority is given to taxonomic revisions and phylogenetic studies employing morphological and molecular data. ISE also welcomes reviews and syntheses that can appeal to a wide community of systematic entomologists. Single species descriptions, regional checklists, and phylogenetic studies based on few taxa or single molecular markers will generally not be accepted.
