Family MICROMIIDAE (Hemerobiidae) 



The genera of Micromiidae known to me from China and adjoining 

 areas can be tabulated as follows: 



1. Forewings with a recurrent vein at base, costal area broadened 



near base 6 



Forewings without recurrent vein, costal area more narrow at 

 base 2 



2. Jledius and cubitus in basal part well separated ; but one series 



of gradates beyond middle of wing; but two radial sectors; 



wings very slender Lachobiella 



Medius and cubitus running close together in basal part; two 



series of gradates ; three or more radial sectors 3 



3. Medius not forked before the cross vein to cubitus ; wings very 



slender; nearly all gradates well separted Nanus 



Medius forked before the cross vein to cubitus ; wing less 

 slender, often many gradates more close to each other 4 



4. Some of costal cross veins near base connected to each other Phlebiomus 



Rarely any of costal cross veins connected 5 



5. But four radial sectors ; gradates much separated Micromus 



More than four radial sectors ; gradates nearer each other Eumicromus 



6. Forewing with but one, a median, series of gradates 7 



Forewing with an outer series also 8
