Brief Summary

provided by Catalog of Hymenoptera in America North of Mexico
During their larval stages the two North American rhopalosomatids are external parasites of nymphal crickets. Gurney (1953) undoubtedly had material of both species before him in his study of the biology and larval stages of what he supposed to be Rhopalosoma only. He recorded as hosts Hapithis a. agitator Uhler, H. agitator quadratus Scudd., H. brevipennis Sauss., H. sp., and Orocharis sp.

Rhopalosomatidae

provided by wikipedia EN

Rhopalosomatidae is a family of Hymenoptera containing about 68 extant species in four genera that are found worldwide.[1] Three fossil genera are known.[2][3]

The adults resemble ants and may be confused with them. They are yellowish with red or brown markings, but may be all brown in colour. Winged species are usually nocturnal, while wingless or reduced-wing species are mainly diurnal. They are solitary, and the larvae are ectoparasitic on orthopteran nymphs. Adults have the tips of two or more antennal segments with spines. The hindwing (when present) has distinct claval and jugal lobes. The metatibia has a calcar or curved spur.[4]

Rhopalosoma is a New World genus (17 spp.) with most species from Central and South America. Olixon (26 spp.) is distributed through Africa and Australia and the New World. Paniscomima (11 spp.) is known from India, Madagascar, Africa, and Southeast Asia.[5][6] Most species of Liosphex (14 spp.) are found from the southern US to Central and South America, with one species, L. trichopleurum, known from the Philippines and Indonesia. Mesorhopalosoma cearae is a fossil known from Brazil.[7]

Taxonomy

The family has four extant and three extinct genera:[8][9]
