Diagnosis. The new species,
Proctophyllodes canora
sp. nov.
, belongs to the
tricetratus
species group. Within this group, the new species is similar to
P. minlae
Atyeo & Braasch, 1966
from
Minla cyanouroptera
Hodgson, 1838
(
Timaliidae
) by having small terminal lamellae and an opisthogastric shield which is split into two pairs of sclerites. The new species can be distinguished from the latter as follows: in male, the terminal lamellae is ovate and with pennate venation; there is a spine-like projection only at the apex of tarsus IV but not ambulacra. In males of
P. minlae
,
the terminal lamellae is rectangular and with radiate venation; and apex of each ambulacra has a spine-like projection except tarsus IV.
Etymology. The specific name,
canora
, is derived from the specific name of the
type
host.
