Genus: Ceratina Latreille, 1802
Subgenus: Copoceratina Terzo and Pauly, 2001
Common name: small carpenter bees
Ceratina (Copoceratina) are small bees with black integument, sometimes with some faint greenish or bronze metallic reflections on the head and thorax, as well as white markings on their head, pronotal lobes, and legs (Pauly et al. 2001). Their forewing length varies between 3–3.5 mm (Pauly et al. 2001).
Ceratina (Copoceratina) is not likely to resemble other Ceratina subgenera and can be distinguished by the unique transverse carina on the supraclypeal area of both sexes in combination with the fine punctures on the integument and the ventral tooth or lobe on the ventral side of the male’s hind trochanter (Pauly et al. 2001).
Ceratina (Copoceratina) madecassa nests have been found in the stems of Scaevola taccada (Goodeniaceae). These nests showed the typical features associated with Ceratina nests, including walls formed of a double layer of clippings, a 7.5 mm space between plugs, 3 cm between occupied cells, and a 1.2 cm entrance to the galleries (Pauly et al. 2001).
There are no known invasives.
Ceratina (Copoceratina) is restricted to Africa: C. minuta is found from Kenya to South Africa, and C. madecassa has been found only on Madagascar and the archipelago of the Seychelles (Michener 2007).
