A.S & AvH, in Malaise traps ( CSE ) . Remark: Parapiagetia arabica was described from a single female from Al Ajban ( Schmid-Egger, 2014 ). Another female collected in Al Wathba agrees with the type specimen, and a male from the same location represents the hitherto undescribed male of P. arabica . Diagnosis of male : The male keys out with P. odontostoma (Kohl) in the key of Pulawski (1977) , couplet 6 (p. 610) and differs by the characters given in Tab. 3 . The species is compared with P. odontostoma males from Algeria , Morocco and Israel . It can be differentiated from other Parapiagetia species in the UAE of the P. odontostoma - group by the long marginal cell (AT shorter than AR). TABLE 3. Comparison of Parapiagetia arabica and P. odontostoma , males.
