摘要

本文展示并描述了波兰始新世琥珀（波罗的海琥珀）中的一种新的 Malthodes（鞘翅目，Cantharidae，Malthininae）：Malthodes (s. str.) maximiliani sp.这种新的兵甲虫的特征是体型较小，最后一个tergite和最后一个sthestite与类似类群不同。值得注意的是，该标本具有部分可见的甲状腺，这一特征在名义亚属的 Malthodes 化石中很少见；在该亚属的 3 个化石种中仅观察到过这一特征。

A new species of Eocene fossil Malthodes (Coleoptera: Cantharidae) with a rarely observed aedeagus.

A new Malthodes (Coleoptera, Cantharidae, Malthininae) in Eocene amber from Poland (Baltic amber) is illustrated and described here: Malthodes (s. str.) maximiliani sp. nov. The new species of soldier beetle is characterized by its small body size and last tergites and last sternite distinct from similar taxa. Notably, the specimen has a partially visible aedeagus, a characteristic rarely seen in fossil Malthodes of the nominotypical subgenus; it has been observed in only three fossil species of this subgenus.

期刊介绍： Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
