Observations on the Subgenus Argas (Ixodoidea, Argasidae, Argas). 4. A. neghmei, New Species, from Poultry Houses and Human Habitations in Northern Chile

Argasid ticks occurring in chicken houses, dovecotes, and human habitations at Calama and Chuquicamata, Province of Antofagasta, in northern Chile, have previously been identified by some workers as Argas persicus (Oken) and by others as probably a local variant of A. reflexus reflexus . Present studies, especially of the larvae, indicate that the Chilean ticks represent a new species of the reflexus (F.) group for which the name A. neghmei is proposed. Adults, nymphs, and larvae are described.
