Among the species with such antennae, there are not many possibilities. I would say, Aglaoschema cyaneum Pascoe.
See if on the ventral side mesosternum parts are red (cyaneum) or dark (albicorne).
The head of cyaneum usually shows green-blue colour. Orthoschema bicoloricorne Fuchs, 1959, has been described on specimen with red head and scape; this taxon is now synonymized with cyaneum by Monné & Giesbert (1992) because of evident intraspecific variations. |

Thank You Pierre for good explanation!
However hard to say, mesosternum is reddish generally but it`s some darkened, so much more then the prosternum. |

Red or reddish... anyway, in this case you have cynaeum, for sure.
If you are interested, you can download on the net the revision on Aglaoschema by Napp, 2007 (PDF)/ Revista Brasileira de Entomologia
There is also another paper in the library, 2008, with new descriptions, but they do not concern the items with bicoloured antennae. |
