Xylocopa (Dasyxylocopa) bimaculata Friese, 1903

( Figures 1 , 2a , 3a, b )

Xylocopa bimaculata Friese, 1903: 202 . Holotype female, Brazil: Rio Grande do Sul (ZMB; examined).

Comments

The name X. bimaculata is used here to encompass only the populations from southern Brazil (additional records also known from northern Argentina and Paraguay; see Hurd 1978, p. 15), with the other available names removed from its synonymy (see X. piligera below). This species is most similar to X. piligera , with the main differences between them indicated in the key above.

Type material examined

The taxon was proposed based on a single female specimen, currently housed in the ZMB collection. The holotype is in perfect condition ( Figure 1 ).
