The holotype of A. nigrinum was borrowed by van der Zanden in April 1992 (as indicated in the box containing Fedtschenko’s types). In the paper on new synonymy in the Megachilidae ( Zanden 1995) , he references the original labels of this holotype, confirming that he possesses the specimen. Following van der Zanden’s death, his collection was donated to the Naturalis Biodiversity Center in Leiden ( the Netherlands). Specimens bear a small label stating “from the collection of van der Zanden”. Tomas Wood (personal communication) searched this collection for the A. nigrinum type from ZMMU, but could not find it.
