Figs 40-41. Xylobates dianl sp.n. - 40: lateral part of coxisternal region, 41: mentum and coxisternal region Anogenital region: Genital setae comparatively long, longer than aggenital and adanal ones. Setae adj and adg in postanal position, ad^ longer than ad 2 (Fig. 44). Material examined: Holotypus (1193-HO-86): No. 74; 11 paratypes: from the same sample. Holotypus and 9 paratypes (1193-PO-86) deposited In the HNHM, 1 paratype in: MHNG and 1 paratype in: NHMN. Remarks: On the basis of the setiform sensillus, the lack of dorsosejugal suture and the position of areae porosae Aa and of the long interlamellar setae the new species belongs to the relationships of Pergalumna fráter Balogh, 1960. It is distinguished from this species and the related taxa ( P. m au rit il Mahunka, 1977, P . longisetosa Balogh, 1960, etc.) by the striate sculpture of its pteromorphae.
