The specimens were collected using Malaise traps from March to November of 2010 and 2011. Two species, Homolobus infumator (Lyle, 1914) and Homolobus truncator (Say, 1829) were collected and identified. The former was recorded for the first time in Iran. Diagnostic characters and geographical distribution of the species are briefly discussed. An illustrated key is provided for identification of the Iranian species. The biology of the genus Homolobus species has been cosmopolitan subfamily and a heterogeneous group of et The Homolobinae van Achterberg, 1979 is a small al. et al. 2012).
