Phthiracarus nigerrimus Berlese , 1920

Phtiracarus nigerrimus Berlese, 1920a, p. 149; Lombardini, 1936, p. 47.

The type-specimen (slide no. 202/34) from La Plata (The Argentine) is still present in the Collection. It has some resemblance to P. globosus sensu Willmann, but it is larger, the dorsal notogastral hairs are curved to the front, and the anterior anal hair is not curved backwards as in globosus, but erect.
