Differential diagnosis
Among two formerly known species, the new species is morphologically similar to
Anisophyllodes intermedius
. The males of
A. candango
differ from
A. intermedius
by relatively wider idiosoma, with the ratio of length to width about 1.9–2, and by the rounded lateral extensions bearing bases of setae
h2
; the females are distinguished by significantly wider terminal cleft, which is 1.2–1.3 times longer than wide. In the males of
A. intermedius
, the idiosoma is much narrower, 2.5–2.7 times longer than wide, and the lateral extensions of the opisthosoma bearing setae
h2
are acute apically; in the females, the terminal cleft is long and narrow, 3.5–4 times longer than wide.

Etymology
The
specific epithet derives from
candango
(
African
origin), a common name meaning those who live, but were not actually born in
Brasilia
(the capital of
Brazil
), the
type
locality of this mite species; the name is a noun in apposition
.
