Grammatical gender Biapertorbis was treated as feminine by Pokorný (species described have a feminine ending) but "Orbis" is masculine in Latin.
ICZN art. 30.1.1. a genus-group name that is or ends in a Latin word takes the gender given for that word in standard Latin dictionaries; if it is a compound word formed from two or more components, the gender is given by the final component (in the case of a noun, the gender of that noun; in the case of any other component, such as a Latin suffix, the gender appropriate to that component) [details]
