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).
