Domadracunculus janovyi n. gen., n. sp. (Apicomplexa: Actinocephalidae) from adults of Ischnura verticalis (Odonata: Zygoptera) in Texas.

Domadracunculus janovyi n gen., n. sp. (Apicomplexa: Actinocephalidae) is described from trophozoites, gamonts, and oocysts collected from adult Ischnura verticalis (Odonata: Zygoptera) in Brazos County, Texas. Oocysts of the new species are axially asymmetric, smooth, and crescentic, features that unite the taxon with the Menosporinae. The new genus is distinguished from existing menosporid genera by an epimerite in the form of a distinctly pleated cup or sucker, without the anterior digitations of Hoplorhynchus or the crown of hooks diagnostic of Menospora.
