NEOTROPICAL HEMEROBIIDAE — NAKAHARA 115 



each side of aedeagus, all slightly shorter than aedeagus, parameres 

 fused, bladelike for their basal two-thirds, apically forming a pair of 

 oblong lobes; a pair of long, slender processes arises from about point 

 of separation of parameres on dorsal side, directed proximally and then 

 dorsally. 



This new species can be recognized at once by the costal crossveins 

 in forewing being very regularly crossed transversally by small veinlets. 

 It represents, in all probability, Kriiger's genus Palaeomicromus 

 (Stettin Ent. Zeit., vol. 83, p. 170, 1922) based on "H (!) schmidti 

 n. sp." from South America, which has never been described. The 

 genitalic characters, however, are absolutely those of the genus 

 Nusalala.

This is by far the most common Neotropical hemerobiid and the 

 most widely distributed. The genitaUc characters were fully de- 

 scribed by Nakahara (loc. cit.).
