Description: 

Alexander, C.P. 1964. The Crane-Flies of Jamaica. Bulletin of the Institute of Jamacia 14: 35: 28.

Summary: 

The occurence of Neolimonia in the Oriental region is marked by a single species from Taiwan, Neolimonia remissa Alexander (pictured above). This genus is based and can be distinguished from other genera by the bulbous rostral projection of the ventral gonostyle which is equipped with two peg-like rostral spines placed near its base and the delicate silken setae that surrounds the spines. The wing venation of the genus is as in Limonia (s.l.).

Distribution: 

Only a single Oriental species is known, Neolimonia remissa, from Taiwan. The remaining species show a strong Neotropical presence, with 39 of the 44 known species being found there. The remaining species, two from the Nearctic and one from the Western Paleactic, have been collected extensively and show widespread distributions.

Larval Habitat: 

Little is known about the larval habitats of the genus as a whole. Neolimonia rara Osten Sacken of North America has been reared from rotten willow (Alexander, 1920) while N. dumetorum (Meigen) was recorded emerging from dead beach wood (Hovemeyer 1998).
