IsTEOTROPICAL HEMEROBIIDAE — NAKAHARA 



119 



Type species: SpinomegalomKs flinti, new species. 



This genus cannot be clearly separated from Megalomus in vena- 

 tional characters. There are a few crossveins connecting the branches 

 of the radial sectors in the forewing near their bases. These basal- 

 radial crossveins may be of phylogenic significance.
