Hecatrishula cryptoleuca (Ansari, 1957)

Brüelia cryptoleucus Ansari, 1957: 164, figs 19, 46, 47, 105–108.

Coahuila: Corvus corax, Las Vacas, no date, R.E.E. & K.C.E. (Williams 1986); Corvus corax sinuatus, Las Vacas, 5 Jul. 1958, C.A. Ely (Gustafsson & Bush 2017).

Note: Williams (1986) identified specimens of Hecatrishula cryptoleuca as “ Brueelia biocellata (Piaget, 1880) ”, but Gustafsson & Bush (2017) argued that Brueelia biocellata (now Hecatrishula biocellata) only parasitises species of the magpie genus Pica Brisson.
