Genus Mesorhaga Schiner, 1868

Type species: Mesorhaga tristis Schiner, 1868 , by original designation.

NOTES. See Bickel (1994, 2007) and Grichanov & Brooks (2017) for diagnosis of the genus. Grichanov & Brooks (2017) have provided a key to all Afrotropical genera of the subfamily Sciapodinae . Bickel (1994, 2007) used such character as

“wing vein M with distinct curved, almost right angle bend” to separate the Australian and New Guinean Mesorhaga geoscopa species group and Mesoamerican Mesorhaga lacrymans species group from other groups. The Afrotropical species with this character ( M. africana Curran, 1927 , M. demeyeri Grichanov, 1998 , M. pauliani

Vanschuytbroeck, 1952 and M. tanzaniensis sp. n.) and opposite character “wing vein M with more gentle curve” ( M. garamba Grichanov, 1999 , M. kirkspriggsi

Grichanov, 2000, M. mahunkai Grichanov, 1997 and M. tsurikovi Grichanov, 1998 )

are quite different from each other in other morphological features. At present it is not possible to associate them with species groups from other parts of the World.
