Mongomioides Brunetti, 1911: 296 .

Type species ­ Limnobia limnobioides Bigot, 1854 (syn. of Trentepohlia (Trentepohlia) trentepohlii ( Wiedemann, 1828)) .

Original description of genus Trentepohlia by Bigot (1854) covers that recently recognized as nominative subgenus. Edwards (1911) decided, that genus Mongoma Westwood 1881 was synonym of Trentepohlia , but retained that name for subgenus “including those species with four posterior cells”.

Trentepohlia are medium­sized slender crane flies with body length not exceeding 10 mm, wing length 7.0­ 12.5 mm. General body coloration yellowish to brownish. Wing elongate, narrow, anal angle small because of shortened vein A 2, but widely rounded. Wings usually unpatterned translucent and strongly iridescent. Wing venation peculiar and is used for separation of genus: Rs branching into two veins R 2 + 3 + 4 and R 5, but R 2 + 3 + 4 further divides into separate branches, thus totally three branches of radial sector enter the wing margin R 3, R 4 and R 5, what is unusual for Limoniinae . Vein R 5, unusually for all crane flies, is fused with M 1 + 2 and forms the anterior border of the discal cell. Discal cell present or absent. Abdomen strongly elongate. Male genitalia with median interruption of ninth sternite, with well developed parameres, and with ventral bridge.

Larva of Trentepohlia is cylindrical, only slightly narrowed behind, covered with numerous fine setae. Spiracular lobes are almost reduced. Spiracles are small, elongate, situated in the upper part of spiracular disc. Tracheal gills four in number, large, constricted into three or four parts. Head capsule moderate in size, compact and not reduced, what is typical for most of Limoniinae . The head is wholly retracted within prothorax ( Alexander, 1920a; Oosterbroek and Theowald, 1991). Pupal body is large at the anterior end, tapering posteriorly. Thorax is smooth, yellowish brown. Abdomen brighter than thorax and bears numerous tubercles. Pronotal breathing horns leaf like, broad, dorsally flattened with scaly apical part. Last abdominal segment of body terminating in two short, chitinized hooks curved outward ( Alexander, 1920a; Oosterbroek and Theowald, 1991). Larvae and pupae develop in water that gathers in the leaf axils of tropical bromeliads ( Picado, 1913), they are also reported from decaying plant material ( Meijere, 1911; Gerlach, 2009).

The genus Trentepohlia accounts for 296 described species worldwide ( Oosterbroek, 2015) (not 313 + 1 according to Mederos­López, Gelhaus, 2014). They are currently divided into seven subgenera based on the wing venation. Totally 9 fossil species of Trentepohlia are described, one of them belongs to subgenus, that is not represented in recent fauna ( Evenhuis, 2014).
