GYGAXIA Delucchi 



Gygaxia Delucchi, 19556 : 145. Type-species : G. saetosa Delucchi, by monotypy and original 

 designation. 



This genus is very close to Euneura Walker but differs in having unusually strong 

 thick bristles on the vertex, pronotal collar, mesoscutum, scutellum, and apex of 

 the gaster ; apical margin of fore wing lacking cilia, postmarginal vein only about 

 1-2 times as long as the stigmal vein, and the latter 1-35-1-4 times as long as the 

 marginal vein.

Type material. Holotype $, Germany, Haimhausen near Munich, 27. vi. 1948 

 (Wichmann) , in Museum d'Histoire naturelle, Geneva. 

 The male of saetosa is unknown. 



Germany. 



Biology. Reared as a hyperparasite of an aphid of the subfamily Chaitophorinae, 

 which had been parasitized by Coelonotns pini (Hal.) (Braconidae), on Acer 

 pseudoplatanits L. (Delucchi, 19556 : 147).

Type material. Coruna clavata Walker. In BM(NH) there are 3 specimens in 

 the British section, none original material. In the foreign section there are 2 $ and 

 2 $ which are clearly the syntypes (misplaced). From the latter a female is selected 

 as LECTOTYPE ; it is card-pointed (remounted) and bears a Waterhouse label. 



Chrysolampus lagenarius Nees. Type <$ destroyed ; I believe, from the description, 

 that it was the same as Coruna clavata Walker. 



Gastrancistrus hierocles Walker. One male, LECTOTYPE ; it bears a printed 

 label " GASTRANCISTRUS Hierocles ".
