The author of this species is Leonora Katherine Doll Gloyd (29 August 1902 near Larned, Kansas - 2 June 1993). She married (1925) Howard K. Gloyd, a herpetologist. Her mentor in odonate studies was Edward Bruce Williamson (1877-1933). Friends called her "Dolly". There are a couple of articles with biographical information, however there is neither a Wikispecies nor Wikipedia article on her. References below, currently both available online.
