[3] This species was first described in 2019 the biologists Victor C. Calvanese, Antonio D. Brescovit, and Lucio Bonato.

These specimens were found in the first layers of soil, 3 to 5 cm deep, under large stones in a single locality in a park in the municipality of São Roque in the state of São Paulo in Brazil.

The type specimens are deposited in the Instituto Butantan in the city of São Paulo in Brazil.

The antennae are relatively short, only 1.3 to 1.9 times as long as the cephalic plate.

A short sclerite is visible in front of the main sternite of the ultimate leg-bearing segment, and this presternite is apparently divided in the middle.

The main sternite of the ultimate leg-bearing segment is wider than long, with a length/width ratio of about 0.8.

Moreover, the first two denticles on the forcipule are separate in A. intermedius but coalescent at the basal margins in A.
