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

, but widely rounded. Wings usually unpatterned translucent and strongly iridescent. Wing venation peculiar and is used for separation of genus:

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
).
