Two unsexed specimens: ‘Odewahn [hw] // Gawler / Odewahn [hw] // Ep. Mülleri / Kuwert typ / 86 [hw Nickerl] // Coll. Nickerl / Mus. Pragense [p]’; ‘Odewahn [hw] // E. Mülleri / Kuwert typ / 23 [hw Nickerl] // Coll. Nickerl / Mus. Pragense [p]’. Remark. Both specimens have no label from Kuwert. They do not correspond to the original description, which indicates a total length of 45 mm (the above mentioned specimens are smaller, 42 mm ), moreover, they are not conspecific with the syntype from Kuwert’s collection in MNHN. Kuwert’s syntype in MNHN fits well the primary description including the total length of the specimen. Episphenoides muelleri is currently a junior subjective synonym of Mastochilus australasicus (Percheron, 1841) .
