Genus Stegana Meigen

Meigen, 1830: 79; Grimaldi (1990) revised diagnosis; Bachli et al. (2004) European species; Brake & Bachli (2008) world catalogue. Type species: S. nigra Meigen, 1830; Zetterstedt 1847: 2577 (= S. furta Linneaus, 1766). AF, AU, NE, NT, OR, PA.

Pyrgometopa Kertész, 1901: 419 . Type species: P. penicillata Kertész . Monotypic. New Synonym. NT

Diagnosis: Wing held against side of body at rest (Fig. 2, 7); apex bluntly pointed, veins R 4+5 and M 1 convergent, apices nearly touching, parallel at apex; C with row of minute, thorn-like spinules at apex (Fig. 31–32). Mid tarsomeres 1–4 with 2 ventral rows minute, overlapping, scale-like setulae (Figs. 34); hind tarsomeres 1–4 with one or two such rows (Figs. 33, 34). Hypandrial complex very elaborate; phallapodeme usually long, fused to phallus and postgonites. Phallic guide usually present.

Comments: Pyrgometopa has all the above-mentioned characters, fitting entirely in the definition of Stegana . The latter genus is cosmopolitan and more diverse in the tropical regions of the world. Furthermore, we have some undescribed species with modifications on the frons and ocellar tubercle that also fit entirely within Stegana and it is probable that they all form a clade within the genus.
