''Bengalia'' is a genus of blow flies in the family Calliphoridae with one authority considering the genus to belong to a separate family Bengaliidae.〔Lehrer, A.Z., 2003, Bengaliidae n. fam. Une nouvelle famille de Diptera Cyclorrhapha. Entom. Croat., 7(1-2) :5-14〕 These bristly and, unlike the greens and blues of most calliphorids, dull coloured flies, are especially noted for their relationship to ants. Little is known of their biology and life-cycle, although adults of many species are kleptoparasitic on ants and will snatch food and pupae being carried by ants or feed on winged termites.〔Sivinski, J., S. Marshall and E. Petersson (1999) Kleptoparasitism and phoresy in the diptera. Florida Entomologist 82(2) ()〕〔Bequaert, J. 1922. The predaceous enemies of ants. Bull. Amer. Mus. Nat. Hist 45:27 l-331. ()〕 ==Description== Most of the species have a yellow or brown ground-colour, an antero-posteriorly compressed head, stout mouthparts, a projecting clypeus below the lower facial margin and have a silent flight. Very little is known about their breeding habits. The genus is found in the Afrotropical and oriental region with one species from Australia possibly a recent introduction. The group (placed at family rank by Lehrer (2005)), has the following morphological characters:〔http://upload.wikimedia.org/wikipedia/ro/e/ef/Bengaliidae_Lehrer_n._fam..pdf〕 * head very depressed antero-posterior * eyes elongate * haustellum is short, large, rigid and has small suction cups and armed with rigid spines and long hairs * the tergite VI is not visible in continuation of the tergite V, but it is in the interior of tergite VII+VII, like a rudimentary sclerite; the sternite VI forms an incomplete ring formed by fusion of two hemisternites; tergite VII+VIII (the genital tergite) does not result from the fusion of segments VII and VIII, the sternite VII being placed in continuity of the sternite VI and the sternite VIII is the base of the phallosome theca; the sternite IX constitutes the origin of the phallapodema (as in both Calliphoridae and Sarcophagidae); the copulatory organ is derived from tergite IX (as in both Calliphoridae and Sarcophagidae); the anal tergite is the tergite X (as in both Calliphoridae and Sarcophagidae); the sternite X is represented by the "processi longi" or "bacilliform sclerites", which are biarticulated; the paralobes are biarticulated; the phallosome has a distinct and very different configuration from that in the typical Calliphoridae. 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「Bengalia」の詳細全文を読む スポンサード リンク
