REVISION OF SPECIES OF STILOBEZZIA KIEFFER 129 



Types. — Holotype female, allotype male, Seoul, Korea, June 1955, 

 light trap (USNM 69485). Paratypes, 2 males, 1 female. KOREA: 

 Seoul, same data as types, 1 male, 1 female. JAPAN: Tokyo, R. 

 Thaxter, 1 male. 



Discussion. — This species is remarkable among the Subviridis 

 Group for its almost entirely pale legs, although structurally it is 

 nearly identical with tokunagai, new species, also from Japan and 

 Korea, which has the usual distinctly dark banded legs of the group.

 spicuous mesad; pubescence not modified; I with cluster of 5-6 

 hairs on each side. Spermathecae (fig. 95i) with the large functional 

 one heavily sclerotized, subspherical, without distinct neck; the second 

 moderately sclerotized, subspherical with a filiform neck as long as 

 diameter of spermatheca, the 2 functional ones measuring 0.080 mm 

 by 0.065 mm, and 0.030 mm in diameter. Genital sclerotization as in 

 figure 951. 



Male. — Length of wing 1.32 mm. 



As in the female with the usual sexual differences including features 

 of the abdominal terga (fig. 95k) ; antennal plumes dark brown. 

 Genitalia (fig. 95f-h) with the following conspicuous differences from
