The original description of the species is founded on specimens from the "Monte Falterona", a mountain in Tuscany. In the Berlese Collection I found indeed two preparations (viz. the nos. 80/9 and 80/10) from this locality; they are designated as type. There is further one slide (no. 146/28) on which "Vallombrosa" (also in the mountains of Tuscany) is recorded as locality.
In
their present state, two slides (nos. 80/9 and 146/28) are not suited for study. No. 80/10 is, however, in a satisfactory condition; it fits in with the description of specimens from the Vosges (Grandjean, 1928). I draw attention to the fact that eyes are distinctly visible in this type-specimen, so that it is certain that Berlese (who did not raention it) overlooked this unique character.
1) In the explanation of the plate, Berlese spells the subgeneric name as
Heterocthonius
