Xylocopa (Schonnherria) are medium sized bees, 14 – 23 mm in length, with dark blue, green, gold, or black integumentintegument:
a tough, protective outer layer
, often with vibrant metallic reflections (Hurd and Moure 1963Hurd and Moure 1963:

Zootaxa 4789(2): 301-347.). They have short pubescencepubescence:
short, fine hair
that can range from black to pale. Their wings are a light brown color and have a very weak yellow or violet iridescent color (Hurd 1978Hurd 1978:

Xylocopa (Schonnherria) occurs from northern Argentina and Chile up north to the southern United States, and then along the coast from Texas to Florida to Virginia (Michener 2007Michener 2007:

a tough, protective outer layer

the apical-most appendage of the male genitalia, which is usually quite hairy

A transverse line on abdominal segments of some bees that is formed by a groove or a step between two regions that differ in height. This line can be well developed and present across the entire segment but can also be diminished or absent through part of the segment, requiring close inspection.
