Remarks.
Cyta leiliae
sp. nov.
closely resembles
C. coerulipes
(
Dugès, 1834
)
in having heavily sclerotized (dark), purple integument and tibiae I, and IV and tarsus III each with a trichobothrium. However, it differs by having: 1) propodosomal striae continuous in
C. leiliae
but sparsely broken in
C. coerulipes
; 2) trochanter I with one seta instead of two; 3) tarsi II with 27ts, 1
w
, 2pe, 1
e
in new species opposed to 19–21ts, 2
w
; 4) tarsi III with 24ts in
C. leiliae
but 20ts in
C. coerulipes
; 5) genu I with three solenidia in
C. leiliae
but two solenidia in
C. coerulipes
.
Etymology.
This species is named in honour of Ms. Leili Eghbalian, daughter of the senior author.
Type
material.
The
holotype
and four
paratype
males were collected from soil and litter under grass and oak trees,
Quercus brantii
Lindl
, (
Fagaceae
),“Sirvan river bank”, located in Palangan village, Kurdistan Province,
Iran
, (
35° 03.7' N
,
46° 35.97' E
, a.s.l.
864 m
),
14.IV.2013
, by Amir Hossein Eghbalian. The
holotype
and three
paratype
females are deposited in the mite Collection of the Acarology Laboratory, University of Bu–Ali
Sina
