A new species of the South American genus Arthurella Albuquerque (Diptera: Muscidae), with a key to species and new records Author Patitucci, Luciano Damián Author Mariluis, Juan Carlos Author Aballay, Fernando Hernán text Zootaxa 2011 2810 56 62 journal article 10.5281/zenodo.206099 0b280f23-cc08-4575-aaf4-27dfd8858ce9 1175-5326 206099 Arthurella Albuquerque, 1954 Arthurella Albuquerque, 1954 :151 . Type-species: Arthurella nudiseta Albuquerque, 1954 , by original designation. Diagnosis (modified from Couri & Penny 2007 ). Eye with sparse short cilia. Arista bare; one pair of long strong ocellar setae; prosternum, anepimeron and meron setulose; dorsocentral setae 2+3-4; intra-alars 2; katepisternals 2+2; vein R1 setulose on dorsal surface; vein R4+5 setulose on both surfaces; vein R4+5 and M diverging slightly to apex; hind tibia with calcar present; sternite 1 bare. Arthurella can be easily distinguished from other Neotropical taxa by the presence of 2+2 katepisternal setae. A few genera of Muscidae ( e.g. , Neurotrixa Shannon & Del Ponte and Lispoides Malloch ) also have the same configuration of katepisternal setae ( Costacurta & Carvalho 2005 ).
