Thread subject: Diptera.info :: Lispocephala alma?

In Fonseca's 1968 key to Lispocephala, this runs easily to couplet 11/14 but then is not so straightforward.

The hind tibia has setae near the tip stouter on the anterior face than on the posterior, and the apical segment of the fore tarsus black except for a very narrow pale strip at the base, much less than a third: L. pallipalpis

The middle lobe of the genitalia is broad with three longitudinal ridges: L. almi

The lobes on sternite 5 have a large rounded distal extension like Gregor et al. 2002 show (fig. 44r) for L. falculata

I'm opting for alma as the middle lobe of the genitalia looks the least doubtful character but I'd appreciate a second opinion please.
