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.
