<p class="Body">First record of the mite genus Denheyernaxoides Smiley (Acari: Bdelloidea: Cunaxidae) for North America and a redescription of D. americanus Rocha et al.

“…Rocha et al (2016) reported differences in the coxal setal count between D. americanus and the Chinese and Ukrainian specimens of D. brevirostris; however, these can be attributed to how propodogastral and hysterogastral setae (see Den Heyer 1981) were treated (i.e., as coxal setae, or not). Illustrations from Lin (2001), Sergeyenko (2011) and Rocha et al (2016), show that D. brevirostris and D. americanus each bear a total of 10 pairs of ventral setae anterior to pregenital setae (including coxal, propodogastral and hysterogastral setae). D. americanus was also recorded as having four setae on femur II by Rocha et al (2016), but examination of the holotype reveals that it has five setae, like D. brevirostris.…”

Furthermore, D. americanus was considered unique in having reticulation on the prodorsal shield and basal segment of the chelicerae in Rocha et al (2016), but reticulation on the prodorsal shield is desclerotized and faint, differing in appearance from the reticulation on the subcapitulum, which is comprised of obvious, sclerotized, external thickenings.…”

In addition, a patch of unsclerotized reticula were noted in Brazilian specimens at lateral margin of prodorsal plate between at and seta mps; however, this patch was not observed in Canadian specimens.…”

“…Three species are presently included in the genus Denheyernaxoides: D. brevirostris (Canestrini 1885), described from trees in Italy and recorded from moss on Quercus pubescens (Fagaceae) in Ukraine (Sergeyenko 2011) and the bark of various tree species in China (Lin 2001); D. martini Smiley 1992, described from an unknown host from New Zealand; and D. americanus Rocha et al 2016, described from lichens and moss on the bark of Ilex paraguariensis (Aquifoliaceae) in Brazil.…”
