利用表型特征和基因特征相结合的方法，对隐甲亚科西部古北区象甲的系统发育进行了研究。这是物种极其丰富的隐甲虫首次使用分子数据(线粒体CO1和16S以及核糖体28S)的系统发育。这项研究的结果表明，在这一形态上神秘的象甲类群中需要分子工具，并提供了一个可以测试属归属的支架。目前的研究主要证实了目前对属的细分(但许多亚属组受到质疑)。记述了三个新属：Montanacalles gen.11月(模式种：Kyklioacalles nevadaens Stuben，2001)，Coloracalles gen.11月(模式种：Aalles humerosus Fairmaire，1862)和Elliptalalles gen.11月(模式种：Aalles long us Desbrocher，1892)。对所讨论的所有分类群的相关外部特征和雄性生殖器进行了图解。三个种被转移到不同的属：Kyklioacalles aube(Boheman，1837)(前身：Aalles)，Ruteria main(Solari A.&F.，1907)和Ruteria minosi(Babr&Bayer，2005)(均前棘形目)。
A phylogeny is presented for the western Palaearctic representatives of the weevil subfamily Cryptorhynchinae using a combination of phenotypic and genotypic characters. This phylogeny is the first for the extremely species-rich Cryptorhynchinae to use molecular data (mitochondrial CO1 and 16S as well as nuclear ribosomal 28S). The results of this study show the need for molecular tools within this morphologically cryptic group of weevils and provide a scaffold based on which genus assignment can be tested. The present study mostly corroborates the current subdivision into genera (but many of the subgeneric groups are questioned). Three new genera are described: Montanacalles gen. nov. (type species: Kyklioacalles nevadaensis Stuben, 2001), Coloracalles gen. nov. (type species: Acalles humerosus Fairmaire, 1862) and Elliptacalles gen. nov. (type species: Acalles longus Desbrochers, 1892). Relevant external characters and the male genitalia of all discussed taxa are illustrated. Three species are transferred to different genera: Kyklioacalles aubei (Boheman, 1837) (formerly: Acalles), Ruteria major (Solari A. & F., 1907) and Ruteria minosi (Bahr & Bayer, 2005) (both formerly Echinodera).
