Sabethes lutzii

Sabethes lutzii is a species name designated a "nomen dubium" i.e., a "dubious (or doubtful) name," for a mosquito specimen that remains insufficiently evidenced to be accepted as a proved species.[2]

Sabethes lutzii was first characterized in 1903 from a damaged specimen collected in Manaós, Brazil, in a letter written by the first scientist to view it, physician Dr. Adolfo Lutz, to entomologist Dr. Frederick V. Theobald who then described it in published literature.[2][3] The specimen was described as large in relative size, of a very dark blue uniform metallic color, and differing from other species by the lack of white scales marking the femurs.[4]

Theobald indicated that the holotype specimen was in the British Museum (Natural History) collection, but it was not located there by a later researcher.[2] More recent researchers have speculated that the holotype specimen may be represented by a slide of a mosquito wing marked "da Coll. do Dr. Lutz/XI-930/C.L." in the Instituto Oswaldo Cruz collection.[5] However, due to the lack of certainty, the name is currently considered a nomen dubium.[1]
