It was described from South Africaand also recorded from the following areas: Afrotropical Region: Kenya, Liberia, Mozambique, Socotra, Tanzania, Transcaucasus in eastern parts of the Afrotropical region down to South Africa(inclusive), United Arab Emirates, Yemenand Zimbabwe( Rhodesia); Palaearctic Region: Afghanistan, Albania, Algeria, Canary Islands, Cyprus, Egypt, southern France(including Corsica), Greece(including Creteand Rhodes), Iran, Israel, Italy(including Serdina, Lampedusa and Sicily), Lebanon, Libya, Morocco, Portugal, Romania, Spain, Syria, Tunisia, Turkeyand Yugoslavia; Oriental Region: northern India, Nepaland parts of Pakistan( Smith & Vockeroth 1980; Peck 1988; Dirickx 1994; Whittington 2003; Birtele et al. 2010; Naderloo et al. 2011; Khosravian et al. 2015; Speight 2020; Smit et al. 2017; Haffaressas et al. 2017; Mebarkia et al. 2020).   Remarks.The larvae of  E. taeniopsare found in standing water containing decaying plant material (e.g. pine needles) or rotting animal carcasses and also in running water contaminated by pig manure ( Haffaressas et al. 2017; Speight 2020). Pérez-Bañóni et al. (2003b) described the larvae and puparia of  E. taeniopsfor the first time, including new morphological characters of the thoracic respiratory process. In addition, they described the morphology of the male genitalia of  E. taeniopsand compared it with that of  E. megacephalus.  Genus  EumerusMeigen The genus  Eumerusis one of the most diverse genera within the Syrphidae, distributed mainly in the arid and semi-arid regions of Eurasia and Africa with approximately 300 described species ( Chroni et al. 2017). There are more than 170 species of  Eumerusin the Palaearctic region and 70 species in the Afrotropical region ( Peck 1988; Kuznetzov 1992; Whittington 2003; Grković et al. 2015; Ricarte et al.2017; Speight 2020; Garcete-Barrett et al. 2020). Most species of  Eumerusare thermophilous and most of them fly quickly near the ground, which makes them difficult to spot ( van Veen2004). The larvae are phytophages and they are considered as pests in commercial bulb plantations attacking pulpy stems and plant organs ( Mutin 2016), causing economic damage to bulbs, stems, roots, or tubers of Amaryllidaceae, Apiaceae, Asteraceae, Iridaceae, Liliaceaeand Solanaceae( Thompson et al.2010; Ohara 2012; Ricarte et al.2017). 3029038335 [415,1318,1616,1643] 2014-05-09 2014-05-30 2014-05-09 CRES H.
