holotype
is deposited in the collections at
NHMG
; two
paratypes
at
SNMB
; one
paratype

Etymology.
The new species is named in honour of Prof. Dr. Leonila A. Corpuz-Raros (
Philippines
) for her valuable contribution in taxonomy of
Cunaxidae
.
Remarks.
The new species
Cunaxa corpuzrarosae
sp. nov.
is similar to the related species
C. potchensis
Den Heyer, 1979
,
C. mageei
Smiley, 1992
and
C. neogazella
Smiley, 1992
by having basifemora III with 3 sts, basifemora IV with 1 sts, missing median plate and straight (not uncinated) telofemoral palpal apophysis.
C. corpuzrarosae
sp. nov.
differs from
C. potchensis
by having 4 pairs of sts between coxae IV and the genital region and a short stout palpal femoral apophysis (5 pairs of sts in
C. potchensis
and long thin palpal femoral apophysis).
C
.
corpuzrarosae
sp. nov.
differs from
C. mageei
by having much shorter hysterodorsal setae (two times longer in
C. mageei
), and from
C. neogazella
by having much shorter hysterodorsal and also palpal tibiotarsal setae (both these setae are two times longer in
C. neogazella
).
