Remarks. This species is believed to have been introduced with agricultural products in 1989 and is presently found in large numbers in La Toma and other streams (Abedrabbo et al. 1993; Gerecke et al. 1995). This species reportedly bites human (Crosskey & Shelley 1994). This blackfly is only permanently established on San Cristóbal, but during the 1998 El Niño event, it became temporarily established on three other islands (Roque-Albelo & Causton 1999).
