Revision of the Oriental species of the Bengalia peuhi speciesgroup (Diptera, Calliphoridae)

The Oriental species of the Bengalia peuhi species-group are revised and their male genitalia illustrated by means of digital colour photography. A key to males is presented, complete synonymies are given for all the species and their geographical distribution reconsidered. The 13 Oriental species making up the group are: Bengalia emarginata Malloch, 1927 (China, Laos, Malaysia, Nepal, Philippines, Singapore, Taiwan, Thailand, Vietnam); B. emarginatoides sp. nov. (India, Sri Lanka); B. emdeniella (Lehrer, 2005), comb. nov. (China); B. fani Feng & Wei, 1998 (China); B. inermis Malloch, 1927 (Philippines); B. latro de Meijere, 1910 (Indonesia); B. lyneborgi James, 1966 (Philippines); B. pseudovaricolor Kurahashi & Tumrasvin, 1979 (Thailand); B. surcoufi Senior-White, 1923 (India, Nepal, Pakistan, Vietnam); B. taksina (Lehrer, 2005), comb. nov. (Laos, Malaysia, Nepal, Thailand, Vietnam); B. unicolor Séguy, 1946 (Pakistan); B. varicolor (Fabricius, 1805) (China, India, Indonesia, Japan, Laos, Malaysia, Pakistan, Singapore, Sri Lanka, Taiwan, Thailand, Vietnam); and B. weii sp. nov. (China). A lectotype is designated for Bengalia latro to fix the interpretation of the name. Bengalia bezzii Senior-White, 1923 is established as a junior synonym of Musca varicolor Fabricius, 1805, syn. nov. Bengalia chromatella Séguy, 1946 and Bengalia pallidicoxa Séguy, 1946 are treated as junior synonyms of Musca varicolor Fabricius, 1805, syn. nov. Afridigalia bezziella Lehrer, 2005 is established as a junior synonym of Bengalia emarginata Malloch, 1927, syn. nov. Afridigalia pinatuba Lehrer, 2005 and Ashokiana ramsdalei Lehrer, 2005 are established as junior synonyms of Bengalia inermis Malloch, 1927, syn. nov. Ashokiana ramsdalei and Afridigalia laguna Lehrer, 2005 are both based on a holotype with a partly destroyed aedeagus. Afridigalia tenggeria Lehrer, 2006 is established as a junior synonym of Bengalia latro de Meijere, 1910, syn. nov. Afridigalia thaisia Lehrer, 2008 is established as a junior synonym of Afridigalia taksina Lehrer, 2005, syn. nov. The Afrotropical Afridigalia walkeriana Lehrer, 2005 is established as a junior synonym of Bengalia depressa Walker, 1858, syn. nov. The Afrotropical Afridigalia zouloupyga Lehrer, 2006 is established as a junior synonym of Bengalia floccosa Wulp, 1885, syn. nov. Afridigalia arawakia Lehrer, 2006 is established as a junior synonym of Bengalia peuhi Villeneuve, 1914, syn. nov. Bengalia taiwanensis Fan, 1965, not a member of the peuhi species-group, is established as a junior synonym of Bengalia fuscipennis Bezzi, 1913, syn. nov. Sri Lanka is deleted from the distributional range of this species. New morphological terms are introduced for the description of the aedeagus. The ovipositor is described for Bengalia emarginata and Bengalia lyneborgi. A preliminary phylogenetic analysis is performed using NONA and Pee-Wee
