The Steganinae Hendel, 1917, is the smaller of two subfamilies in the fruit fly family Drosophilidae. The other subfamily is the Drosophilinae.
Diagnosis
The subfamily is monophyletic (Grimaldi 1990; Sidorenko 2002), but can not be characterised by a single morphological character that distinguishes this subfamily from the Drosophilinae. See for a discussion on this subfamily "Drosophila: A Laboratory Handbook" by M. Ashburner, S. Hawley, K. Golic (not reproduced here due to copyrights).

Phylogeny
The phylogenetic relationships within the subfamily have not yet been confirmed by molecular studies, and are partially based on traditional cladistic methods using primarily morphological characteristics and partly based on expert opinions. The classification below might be not approved by all scholars in the field, but gives a reasonable overview of our current knowledge:
Tribe: Steganini Subtribe: Steganina Genus: Eostegana Genus: Stegana
Subtribe: Leucophengina Genus: Allopygaea Genus: Cacoxenus Houdini fly inflates head to break walls Genus: Leucophenga
Tribe: Gitonini Subtribe: Gitonina Genus: Amiota Genus: Apenthecia Genus: Apsiphortica Genus: Cacoxenus Genus: Crincosia Genus: Erima Genus: Gitona Genus: Paraleucophenga Genus: Paraphortica Genus: Phortica
Subtribe: Acletoxenina Genus: Acletoxenus Genus: Hyalistata Genus: Mayagueza Genus: Pseudiastata Genus: Rhinoleucophenga Genus: Trachyleucophenga
Subtribe unknown Genus: Electrophortica Genus: Pararhinoleucophenga Genus: Parastegana Genus: Pseudostegana
Tribe unknown Genus: Soederbomia Genus: Pyrgometopa
