Statistics
In this family the dorsal rim of the torulus is simple, but the
frons is swollen above it (Brothers & Finnamore 1993) The eyes have a
straight inner margin. This cosmopolitan
family has about 12 identified species found in Tropical Northern Hemisphere
America and Asia. Little is known
about their biology, except that most are ectoparasitic as larvae. The adults are black or brown, and all
known species are solitary ectoparasitoids of other insects The coxa of the hind and middle legs are close to each
other and the hind wing does not have claval or jugal lobes. The first
metasomal segment does not have a true node but nevertheless appears like
that of the Formicidae. The metasomal sternum of the first segment is
separated from the second by a constriction. Sexual dimorphism varies among
species from slight to noticeable with both males and females having wings
but females are sometimes apterous. The larvae are believed to be ectoparasitoids of other
insects. Six of the known American
species range from the Yukon to Panama and Hawaii (Brothers & Finnamore
1993). = = = = = = = = = =
