Park, 07°50'35''S 36°49'49''E,  11–13. xi.2009,  1000 m, T. Pape& S. A. Marshall( DEBU#00318741, deposited in ZMUC).   Paratype ♀: Same data as holotype, in 95% alcohol ( ZMUC). Other material examined:  TANZANIA: “Tanganyika, W. Usambara Mts,  2100m, Magamba,  iii.1962” (1 mouldy and psocid­damaged ♀, CNCI). Material remarks: The non-type material examined is probably the same species as the specimens from the Udzungwa Mountains, but not designated as a paratypebecause of the poor condition of the specimen and also the disjunct locality. New material is required to either confirm that the distribution of  A. undzungwaextends to the Usambara Mountains, or whether it is part of a closely related but disjunct pair of Eastern Arc species, like  A. melasmaand  A. metamelasma. Comments: Despite the dark colour and the outer vertical setae, this species is similar to the previously described species of  Aristobatina,and is probably more closely related to  A. rufithoraxand  A. principalisthan to the other species described here. The larger size, lack of longer setae on the pedicel, relatively strongly angled CuA 2and the virtually identical spermathecae all suggest that these three species are closely related, although males are unknown for  A. udzungwa sp. n.and no data are available on the spermathecae of  A. principalis. ACKNOWLEDGMENTS Thanks go to Thomas Pape for making the Udzungwa Expedition possible, and for his excellent company in the field.Thanks also to Ashley Kirk­Spriggs for his substantive help in editing the manuscript.Specimens were collected under COSTECH permit 2012­357­NA­2012­147. 2009-11-11 2009-11-13 2009-11-11 A, ZMUC T.
