Identification
"The epigynum of the female, unlike that of K. alba, has a flat, triangular, curved scape, the tip projecting anteriorly and, like K . alba but unlike others, no humps or tubercles on the posterior of the abdomen. The tiny male can be separated fro m others by having a palpus with only three or four long, black teeth on the distal end of the median apophysis and by the shape of the conductor, pointed and longest on the side of the dark terminal apophysis"
Range
In the USA found only in the LRGV of southernmost Texas. Found south from there through southern Brazil and northern Argentina.
Habitat
Both Texas specimens were found in low woody vegetation (shrubs or small trees). South American specimens have been collected from the forest canopy.
Life Cycle
One specimen was found in Costa Rica in the possession of the wasp Trypargilum nitidum.
Remarks
At least two individuals from Hidalgo County TX - one examined by Levi, the other photographed and posted here - have posterior tubercles on the abdomen that are apparently absent in specimens from further south
