| Summary: | Hydroporus polaris Fall, 1923 Fall (1923: 92) described this species from two males and one female from Bernard Harbour (Nunavut, Canada, ca. 68.788N 114.82W; square 9 in Fig. 13). In the same work Fall (1923: 93) described Hydroporus subvirescens after specimens collected at Cape Collinson (Alaska, USA, ca. 69.986N 144.861W; square 8 in Fig. 13). He provided for this taxon the following features: "with evident viridi-aeneous surface lustre" on the elytra and a "distinctly alutaceous and dull" upper surface. Additionally, he wrote: "Front tarsi of male moderately dilated, its anterior claw not appreciably different from the posterior." We have studied the male holotype and the female paratype of H. polaris as well as the male holotype of H. subvirescens (all in CNC). To our great surprise, the holotype of H. polaris has a "distinctly alutaceous and dull" upper surface with a well visible metallic sheen on the elytra (sic!), while the holotype of H. subvirescens has a shiny (although reticulate) surface and ... : Published as part of Jia, Fenglong, Zhao, Shuang & Fery, Hans, 2012, Hydroporus sejilashan sp. n., a new diving beetle of the acutangulus - complex from Xizang, China (Qinghai-Tibet Plateau), and notes on other taxa of the genus (Coleoptera, Dytiscidae, Hydroporinae), pp. 55-67 in Zootaxa 3223 (1) on pages 63-64, DOI: 10.11646/zootaxa.3223.1.4, http://zenodo.org/record/210833 ... |
