Abstract - Morphological descriptions using measurements common to honey bee taxonomy are provided for Apis andreniformis Smith (1858) from southeastern Thailand and Palawan, Philippines and Apis florea Fabricius (1787) from southeastern Thailand. Overall, A andreniformis has a very different morphology from the sympatric A florea and from all other well-described species of honey bees. One difference, the color of the scutellum, although not species specific, is sufficient in many cases to facilitate field identifications. Very few morphological differences occurred between the Thai and the Philippine populations of A andreniformis.
