- The drawings of the original description of B. portheo Akbar & Khalid are exactly the same as those of the original description of B. portheo Chaudhri & Akbar. The site of collection of the former species (2 km south of Karachi) is also similar to that of the latter (2 miles south of Karachi). Despite of the minor differences in the collectors and collection dates, they appear to be the same species and therefore B. portheo Akbar & Khalid is a primary homonym and junior synonym.;
