Diagnosis. Both sexes of H. ferruginea clearly differ from H. ingrica ( figs 5–8 ) by the longer body, 9.0– 13 mm (in H. ingrica , body length 5.5–8.0 mm), and plumose arista ( fig. 3 ), with its branches> 2× as long as the maximum diameter of the arista (in H. ingrica , arista with shorter microtrichia ( fig. 7 ), the longest branches slightly longer than the maximum diameter of the arista). Additionally, H. ferruginea can be separated from H. ingrica by: hind coxae covered with numerous short black setae ( Mutin & Barkalov, 1999) as well as katepisternum with several (8–12) long black setae posteriorly ( fig. 4 ) (in H. ingrica , katepisternum without black setae, and hind coxae mostly with 2–3 long black setae only in outer posterior corner laterally and the same amount at the posterior edge, as on fig. 8 ); female tergite 2 ( fig. 2 ) usually with pale anterolateral part that do not look like separate maculae (in H. ingrica , female tergites 2 and often 3 with pale maculae that look like a separate maculae ( fig. 6 ), especially on tergite 2).

N o t e. The only representative of the genus in Ukraine. In Great Britain, this species is listed under the UK Biodiversity Action Plan and qualifies as Endangered ( Ball & Morris, 2014).
