Type species ­ Mongoma fragillima Westwood, 1881 .

Separation of this subgenus is based on the combination of some characters of the wing venation, as follows: three branches of Rs ending in the wing margin ( R 3, R 4 and R 5 which is fused with M 1 + 2 and forms the anterior border of the discal cell), two Medial veins (M 1 + 2 and M 3) ending in the wing margin, discal cell present and four veins issuing from it ( R 5, M 1 + 2, M 3 and CuA 1), CuA 2 intersecting A 1, closing cell cup, what is unusual not only for crane flies, but for all Nematocera.

Subgenus Mongoma is the most species­rich among subgenera of Trentepohlia , with 141 described species. It is very well represented in the Oriental Region, of which 71 species are listed. Species have also been reported from other regions, as Afrotropics (22 species), Australasian / Oceanian (46 species), East Palaearctic (3 species), and Neotropical (3 species) ( Mederos­López, Gelhaus, 2014; Oosterbroek, 2015). 2 fossil species are ascribed to Mongoma from Eocene/Oligocene of England ( Evenhuis, 2014).
