Four new species and new records of Thinophilus Wahlberg, 1844 (Diptera: Dolichopodidae) from Iranian mangroves with a key to the species known from Iran

Abstract

Four new long-legged fly species, Thinophilus albihirtus sp. n., Thinophilus albisetosus sp. n., Thinophilus nigrihirtus sp. n., and Thinophilus qeshmensis sp. n., from southern Iran, all collected in or near the mangrove forests, are described and illustrated. Four more species of the genus are collected from the same localities. Polyzonal T. indigenous Becker, 1902 is found in the Fars Province. Three known species are firstly recorded from Iran (T. deemingi Grichanov, 2023, T. gallagheri Grichanov, 2023 and T. ochripalpis Becker, 1910). The Iranian species are considered members of one Oriental (T. murphy group), two Afrotropical species groups (T. gallagheri and T. calopus groups) and T. indigenus lineage distributed widely in the Old World. A check-list and identification key to males of 12 species known from Iran are provided.
