Xylocopa (Schonnherria) dimidiata Latreille 1809: 95

Fig. 14

Known distribution. Argentina, Brazil (Amazonas, Mato Grosso, Pará, São Paulo), Bolivia, Paraguay, Peru (Hurd 1978: 17). Type locality: not stated in original description (Latreille 1809: 95).

Notes. This species was recorded by Hurd (1978) from the Brazilian states of Amazonas and Pará but there are no specimens from either state in USNM. The characters in the key are taken from specimens collected at localities from Bolivia and Peru outside the Amazon River basin. The combination of metallic blue dorsal coloration and black pubescence on the metasoma appears to be diagnostic for the female of this species, at least among the Amazon Basin species of subgenus Schonnherria .
