LlMNEPHILIDAE 



Limnephilus may a, new species 



Figures 68-70 



The species is perhaps closest to L. hamifer Flint, from which it is 

 differentiated immediately by the sharp hook arising from the mes- 

 oventral angle of the cercus. 



Adult. Lenth of forewing: male 12-13 mm, female 14-15 mm. 

 Color brownish, wings faintly irrorate, with darker specks along 

 veins. Basal segment of foretarsus in male about one-third length 

 of second segment; forefemur and tibia with a band of dark spicules. 

 Male genitalia: Eighth tergum without apicomesal spiculate lobe. 

 Cercus with a broad dorsolateral lobe, and an erect, dark, hooklike 

 mesoventral process. Tenth tergite low, darkened, developed into 

 a short apicodorsal point. Clasper united to posterior margin of 

 ninth segment, but with a short, quadrate, dorsal prolongation. 

 Aedeagus with lateral arms strongly sclerotized, curved dorsad and 

 ending in a sharp point; central tube with a pair of apicolateral 

 heart-shaped plates and a central beak.

Leptoceridae 



Triaenodes anomala, new species 

 Figure 71 



This species is not related obviously to any described North 

 American species of Triaenodes. The short, sharply curved basal 

 spine of the clasper, short, pointed tenth tergite, and paired dorsal 

 spines of the aedeagus are all unique. 



Adult. Length of forewing 6 mm. Specimens pale brown, but 

 completely denuded. Male genitalia: Ninth segment slightly ex- 

 panded ventrally, with ventroapical section supporting claspers
