| Comments | In part. See Ref. 45707. From Ref. 45707: Roberts (1989) treated the only known specimen of B. hypselurus (RMNH 16048) as conspecific with B. insignis because at that time it was the only known male specimen of Breitensteinia. However, he recognized that the differences between it and the other material he had on hand were of such a nature that they might not be attributable to sexual dimorphism but to differences between species. Fresh material of B. insignis has revealed the nature of sexual dimorphism in Breitensteinia and shows that sexual dimorphism in Breitensteinia takes a different form than the differences between B. hyselurus and other Breitensteinia species. Roberts' (1989) suspicion that two species may be involved was correct. |
