Cladotanytarsus Kieffer (Diptera: Chironomidae): several distinctive species reviewed on the basis of records from Canada and USA Author Puchalski, Mateusz Author Giłka, Wojciech text Zootaxa 2017 4242 2 344 358 journal article 36303 10.11646/zootaxa.4242.2.7 8632c8ac-22fd-42bc-b95c-820c0c029c20 1175-5326 376427 8511A4B8-D82F-49EE-9132-E941B4C5D2C4 Cladotanytarsus viridiventris (Malloch) Tanytarsus viridiventris Malloch, 1915 : Malloch 1915 : 491 (adult male; USA , Michigan ).? Cladotanytarsus viridiventris ( Malloch, 1915 ) : Oliver et al . 1990 : 56 (in catalogue, distribution); Bilyj & Davies 1989 : 949 (pupa, in key); Giłka 2011b : 24 (remarks). Remarks. The specific name has so far presumably been erroneously and repeatedly ascribed to various species ( Giłka 2011b; J. Sublette, pers. comm. ), and a subgeneric placement for Cladotanytarsus viridiventris cannot not be defined with certainty. For this reason it is not included in the present key. Nevertheless, a male specimen originally illustrated, having an elongate anal point and a long stem of the median volsella ( Malloch 1915, pl. xxxvi, fig. 8 ), couples with C. acornutus , C. bilyji , C. muricatus or C. nigrovittatus . Following Malloch’s figure, the triangular superior volsella separates C. viridiventris from C. bilyji and C. muricatus , and the relatively short digitus and apically rounded inferior volsella from all the species compared.
