Characters of Leucorhoenanthus of unclear phylogenetic status. (1) Imaginal and subimaginal paracercus is vestigial, consists of several segments. Non-unique apomorphy (see Index of characters [2.3.22]); among Neoephemera/fg1 the same in Potamanthellus/g1; possibly synapomorphy. (2) On fore leg of male imago both claws are blunt (in subimago ephemeropteroid). Non-unique apomorphy (see Index of characters [2.2.77]); among Neoephemera/fg1 the same in Potamanthellus/g1 and Pulchephemera; possibly synapomorphy. Plesiomorphies of Leucorhoenanthus. Larval and adult patella-tibial suture is developed on middle and hind legs (unlike Ochernova). In larva: thoracic terga without protuberances (unlike Neoephemera/fg2); caudalii without secondary swimming setae (unlike Potamanthellus/g1). In imago: gonostyli are not diminished; median incision of penis is small (unlike Potamanthellus/g1). Larval and adult patella-tibial suture is developed on middle and hind legs (Kluge 2004: Fig.83:G) (unlike Ochernova). |
