Rhopalosomatidae is a family of Hymenoptera containing about 68 extant species in four genera that are found worldwide. Three fossil genera are known. 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. ''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. 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. ==Taxonomy== The family has four extant and four extinct genera: *''Eorhopalosoma'' † Engel, 2008 *''Liosphex'' Townes, 1977 *''Mesorhopalosoma'' † Darling, 1990 *''Olixon'' Cameron, 1887 *''Paleorhopalosoma'' † Nel, Azar & Hervet, 2010 *''Paniscomima'' Enderlein, 1904 *''Propalosoma'' † Dlussky & Rasnitsyn, 1999 *''Rhopalosoma'' Cresson, 1865 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rhopalosomatidae」の詳細全文を読む スポンサード リンク
