Macrocilix taiivana Wileman 

 (PI. 13, fig. 380) 

 Macrocilix taiwana Wileman, 1911 : 148. 



Distinguished from its closest apparent relative, orbiferata, by the colour-pattern 

 and by the female genitalia (the male is unknown). The chief distinguishing 

 characters in the genitalia are the signum which extends for almost the whole length 

 of the corpus bursae, the presence of a deep invagination of the posterior margin of 

 the eighth abdominal sternite into which the ostium opens, and the ductus bursae 

 which is more heavily sclerotized than in orbiferata and is strongly constricted a 

 short distance before the ostium. 



Distribution. Unknown outside Formosa.
