Type-material
:
Holotype
female
(No. AM-20130411-1), found in around Siahoo village, vicinity of
Bandar Abbas
City,
Hormozgan Province
, southern
Iran
, (
27.72° N
,
56.33° E
, altitude
578 m
) detached from abdominal tergites, under elytra of
Syntomus
lateralis
(
Motschulsky
)
(
Coleoptera
:
Carabidae
) (type-host), collected by
Abdolazim Mortazavi
,
11 April 2013
, deposited in TMU
.
Paratypes
:
2 adult
females
,
3 males
and 1 larval
females
, with the same collection data as the holotype in TMU;
1 male
and
1 adult
female
UMMZ
. The other paratypes and the beetle host are deposited in TMU

Etymology
: The name of the new species refers to ancient name of the
type
locality, Gombroon (the former name of
Bandar Abbas
City).
