H. patella, which was considered conspecific with H. patelliformis by Remm & Elberg (1980), varies in details of the male genitalia.

Head profile of H. thalhanuneri. Fig. 4. Head profile of H. patelliformis. species near patella from Israel (Freidberg & Yarom, 1990). H. patella, which was considered conspecific with H. patelliformis by Remm & Elberg (1980), varies in details of the male genitalia. It lacks the bifurcate hypandrial appendage and has much larger cerci. The jowls are wider, about two-fifths the eye height. H. spinidorsum has genitalia resembling H. thalhammeri but with obviously larger cerci and aedeagus. It also has fairly narrow jowls (one-quarter of the eye height) but only four rows of acrostichals. These flies are most frequently encountered by sweeping scrub, isolated shrubs, trees and adjacent tall herbage or coarse grasses, and with practice can be distinguished from other orange-bodied lauxaniids by a combination of colour, size and shape. In my experience, a particular fondness is shown for Salix species, especially sallows, though one Coventry record of//, patelliformis was from beneath an isolated weeping willow Salix babylonica L. and I have taken both species away from sallow. Both species will utilize dry and marshy locations and are clearly not confined to either high quality or older habitat. I am unable to detect any obvious differences in their.
