Phradonoma nobile (Reitter, 1881) ( Fig. 1 )

Material Examined. USA: A r i z o n a, P i n a l County, Casa Grande, 29.ix. -3.x.2009, W. B. Warner collector, 1 female, voucher specimen in the collection of A. Herrmann. The exact location is at the SW corner of Kleck Road and Evens Road in Casa Grande , Arizona, at 32°54′31″N, 111°38′ 45 ″W, elevation 432 m (1,416 ft) .

Remarks. The single female specimen was collected during the day on flowers of Isocoma acradenia (Green) (Asteraceae) blooming next to a couple of large cattle dairies and a calf facility. It is a scraped over area of desert with some native plants regrowing. Hypothetically, the dairies may have imported feeds infested with the dermestid.

Distribution. The species is known from Cyprus, England (introduced), Greece, Portugal, Spain, Algeria, Egypt, Eritrea, Libya, Morocco, Namibia, Nigeria, South Africa, Sudan, Tanzania, Tunisia, Zimbabwe, Afghanistan, “Caucasus”, India (Madhya Pradesh, Rajastan, Uttar Pradesh), Iran, Iraq, Israel, Jordan, Pakistan, Qatar, Saudi Arabia, Syria, Tadzhikistan, Turkmenistan, United Arab Emirates, and Uzbekistan (Háva 2003, 2011). This is the first report of the species in the USA, where it is likely an introduced species.

Species more or less broadly distributed..................................................16A

16A. Anterior tibiae with spines along shaft......... ................................................ Phradonoma

16A′. Anterior tibiae without spines along shaft......................................................................16

16. Antennal fossa at least partially enclosed behind by knife-like carina. Metasternum without transverse stria near anterior margin. Elytral markings variable.......... Trogoderma
