This genus at present contains two South American species described 
by Alexander. The new species described below, together with the two 
obviously allied Australian species Limnophila lawsonensis Skuse and 
` L. australasiae Skuse, differs from the polio BS (O. lloydi Alex.) in the 
longer vein Sc; in the absence of a lyriform plate on the ninth sternite of 
the male; and in the extremely short tibial spurs (this at least in the New 
Zealand species). I had at first intended creating a new genus for these 
three species, but have refrained from doing so, as the second species just 
described by Alexander (O. argentinicola) seems intermediate as regards 
- length of Sc and the structure of the hypopygium, and has short tibial 
purs. Orolimnophila must ment be regarded as common to the 
Austin and Neotropical region 
It was suggested by Bergroth (Wien. Ent. Zeit., vol. 9, p. 123, 1890) 
that L. lawsonensis and L. australasiae might belong to Phili pis genus 
Lachnocera. "This opinion may eventually prove to be correct; there are 
certainly some strong resemblances, but Philippi's figure shows remarkably 
elongate scapal joints in the male antennae, whereas in Orolomnophila these 
joints are very short. A final decision on this point cannot be made until 
Philippi’s L. delicatula has been rediscovered.

he specific name has allusion to the “ washed-out " wings, the two 
Australian species of the genus both having conspicuous wing-markings.
