Comment. The taxonomic status of the larvae of H. lobata McLachlan 1884 and H. artax Malicky & Lounaci 1987 is somewhat contentious. Botosaneanu (1999) synonymized H. artax with H. lobata , but Malicky (1999, 2004), Neu et al. (2018) , Tobias & Tobias (2008) , and Samraoui et al . (2020) considered both to be valid Maghrebian species occurring in Algeria . This Ibero-Maghrebian species is reported for the first time in El Harrach Wadi ( Fig. 3 ).
