Is this Tetracnemoidea sydneyensis? - Tetracnemoidea sydneyensis - Female
Long Beach, Los Angeles County, California, USA
September 25, 2013
Size: 2-3mm
Compare to Mike Rose's female photo on Dr. Noyes's chalcid database here.

California is listed under its distribution... assuming its native to Australia though, probably introduced as a biological control (for mealybugs?)

EDIT: I've found more info on this species by searching its previous name (Anarhopus sydneyensis). This article is most relevant. To summarize: this species was introduced into Southern California in 1933 to control an outbreak of the Long-tailed Mealybug Pseudococcus longispinus

Confirmation
Per Dr. John Noyes, encyrtid specialist in London and author of the Universal Chalcidoidea Database, this certainly looks like Tetracnemoidea sydneyensis.
