A new tribe record for the Darkling Beetle fauna of Iran (Coleoptera: Tenebrionidae)

Members of the tribe Scaurini Billberg, 1820, have been systematically studied by Solier (1838), Reitter (1914), Koch (1935, 1958), Peyerimhoff (1948), Español (1954, 1960), Antoine (1953, 1954), Kocher (1958, 1964), Reymond (1956 a, 1956 b) and Labrique (1992, 1995 a, 1995 b, 1995 c, 2001, 2004, 2006). The tribe is recorded from the Mediterranean region, South Africa (Koch 1958), USA: California, Arizona and Texas as well as Mexico (Kaszab, 1982). They are recognized by lack of wings, the keeled eye, conical maxillary palp and hairless antennae with a lengthened last segment and a ridged thorax base (Reitter, 1914). Many species are lapidicolous and myrmecophilous, simulating rigor mortis when disturbed. Some species are troglobite (Antoine 1953).
