Abstract

The new monotypic subgenus Stenolassus subgen. nov. of the genus Stenohelops Reitter, 1922 is described for Stenohelops klebsi (Nabozhenko, Perkovsky et Chernei, 2016) comb. nov. (Coleoptera: Tenebrionidae), which was previously described within the genus Nalassus Mulsant, 1856. This species is transferred to Stenohelops Reitter, 1922 based on the structure of the male aedeagus, abdominal ventrite 5, and the protarsi. A key to the subgenera of the genus Stenohelops is provided. The problematic species Isomira (Mucheimira) avula Seidlitz, 1896 is redescribed and its taxonomic placement addressed. A new species, Isomira (Isomira) hoffeinsorum sp. nov. is also described from Baltic amber. This new species possesses a mixture of characters associated with Mucheimira and Isomira, which can be a result of incomplete diversification of the genus Isomira during the Eocene.

波罗的海琥珀始新世Helopini的分类学注释及Isomira Mulsant属述评(鞘翅目:拟甲科)

新的单型亚属Stenolasussubgen。Stenohelops Reitter属的nov.，1922年被描述为Stenoheloops klebsi（Nabozhenko，Perkovsky et Chernei，2016）梳。nov.（鞘翅目：Tenebrionidae），其先前被描述在Nalassus Mulsant属内，1856年。根据雄性aedeagus、腹部腹肌5和前足肌的结构，该物种于1922年被转移到Stenohelops-Reitter。提供了一个狭叶藻属亚属的钥匙。问题物种Isomira（Mucheimira）avulaSeidlitz，1896被重新描述，并解决了其分类学位置。一新种，Isomira（Isomira）hoffeisorumsp。nov.也是从波罗的海琥珀中描述的。这一新物种具有与Mucheimira和Isomira相关的混合特征，这可能是始新世Isomira属不完全多样化的结果。

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.
