Rockhampton Austral. M. G. 3499. Old type catalogue. Weidner (1960), p. 64, No. 8. Holotype. Taxonomic remarks. Kohlrausch (1879: 74) cited L. Koch as in litt. and listed Cormocephalus calcitrans L. Koch as a junior synonym of his B. calcitrans. He also noted similarities with B. astenon but argued that more specimens were needed for a detailed assessment. Kraepelin (1903: 114 – 115) re-examined the specimen and synonymized B. calcitrans with Otostigmus astenus. Weidner (1960: 64) refers to Cormocephalus calcitrans L. Koch given in Museum Godeffroy Catalog Nr. IV: 53 as a nomen nudum. Lewis (2010) pointed out that there is a specimen identified as C. calcitrans L. Koch from Upolu, Samoa at the BMNH (No. 13.6.18.7.27). This specimen is part of the Godeffroy collection and was also listed by him under O. astenus. It is not possible to know whether Kohlrausch and Koch referred to the same or different specimens. Collection remarks. The specimen came from the private Museum Godeffroy in Hamburg and was collected by Amalie Dietrich (1821 – 1891) between 1864 and 1866. Current systematic position. Junior synonym of Otostigmus (Otostigmus) astenus (Kohlrausch, 1879) according to Kraepelin (1903: 114).
