Hartop, Emily A., Brown, Brian V. & Disney, R. Henry L., 2015, Opportunity in our Ignorance: Urban Biodiversity Study Reveals 30 New Species and One New Nearctic Record for Megaselia (Diptera: Phoridae) in Los Angeles (California, USA), Zootaxa 3941 (4), pp. 451-484 : 462

Megaselia hoggorum new species (Figs. 15, 47, 77, 108)

Diagnosis. Male. In the group III key of Borgmeier (1964), M. hoggorum keys to M. spiniclasper Borgmeier which it differs from noticeably and immediately in the structure of the genitalia. M. spiniclasper has on the left side of the epandrium a single, long, curved projection bearing a terminal bristle. M. hoggorum bears two much more subtle, rounded ventral projections off corners of the epandrium ( Fig. 77 ), which are similar to those of M. dilatata Brues (which comes out later in the key). Upon examination of type material, it was found that although the external structures of the genitalia of M. hoggorum and M. dilatata were similarly shaped, M. hoggorum lacked the prominent and largely protruding phallus complex visible on all specimens of M. dilatata . Additionally, M. hoggorum has much stronger epandrial setation.
