7. Nomia (Maculonomia) apicalis Smith, 1857 , Blacktipped Forest-Nomia

The male holotype in OUM was collected by Wallace in Singapore ca. 1854. Subsequent records in Singapore extend to 1976, when it was last recorded at Dairy Farm. This species persists at PBS, but in Singapore all recent (2008 onwards) local records of a bee with similar appearance pertain to what we believe to be a similar undescribed species, Nomia (Maculonomia) sp. 1 aff. apicalis (description in preparation). True Nomia apicalis seems to be a forest-associated species, whereas the similar morphospecies now present in Singapore has broader habitat tolerances.
