Cordillopsyche costalis Banks, 1913b, p. 238. — Lestage, 1925b, p. 105. — Fischer,

The genitalia of the female holotype of this Colombian species are 

 shown in figures 26 and 27.

The holotypic male has lost all parts of the genital capsule beyond 

 the ninth segment. The parts remaining and the original drawing 

 indicate that this is a typical species of Xiphocentron. 



Xiphocentron Iwitiensis (Banks) 



Antillotrichia haitiensis Banks, 1941, p. 402. 

 Xiphocentron haitiensis (Banks). — Flint, 1964, p. 26.

I am not presenting a complete synonymy of auripenne; rather, 

 one may consult the extensive bibliography in Fischer (1963). 



The holotype of extensum seems to fall well within the extremes of 

 the very variable auripenne.
