Ralliaola mystax (Giebel, 1874) 



Nirmus mystax Giebel, 1874. Insecta Epizoa: 301. 

 Type host: Porzana porzana Linnaeus. 

 New England host: 

 Porzana Carolina (Linnaeus) — Sora. 



Head long and slender with a wide hyaline margin. Antennae 

 sexually dimorphic, 1st segment of the male antenna enlarged and 

 elongated with an appendage. Abdominal segment II with tergite some- 

 times divided, the other tergites transversely continuous in both 

 sexes. Abdominal sternites III-VI with 4 long setae on the posterior 

 margins. 



There are 2 species of Ralliaola found on the Sora; thus, all 

 records published before 1957 when the 2nd species was described must 

 be questioned. Emerson (1957) reports this species from Idaho.
