Taxonomy of European Damaeidae (Acari: Oribatida) II. Porobelba weigmanni n. sp. (Oribatida, Damaeidae), from East Slovakia, with comments on other known species of the genus Miko, L. 8SZQS Arachnida Damaeidae Porobelba CoL Animalia Sarcoptiformes 59 Arthropoda species parki   During the study of damaeid mites from the collection of Karl Strenzke in the Senckenberg Museum, Frankfurt, Germany, I had an opportunity to study one mounted adult individual, probably sent to Strenzke directly by A. P. Jacot. The slide is labelled " SMF 16926: Porobelba, 350, Belbidae. Old Tawney's Cave, Twilight zone; Thulss - Mt.Lake; Hoyer-H.G.S". It is not part of the type series, which was from forest floor near Mammoth Cave, Kentucky. The specimen is in comparatively good condition, but the notogaster is crushed. This species differs from European species of Porobelbaby several important characters. The body is strongly narrowed in the sejugal area (Fig. 4B). The prodorsum has a well developed propodolateral apophysis P. The parastigmatic apophyses are differently shaped: Sa is strong, long, perpendicular to the body, pedotectum-like ;Sp is much smaller, triangular, oblique, well separated from Sa. The discidium is small, thorn-like, oriented anterolaterad. Notogastral setae are similar in size anteriorly (c1 = c2), but diminish posteriad. In all European species of Porobelba, notogastral setae are arranged and oriented radially, whereas in P. parkithey are inserted in two paraxial rows, as found in some other genera of Damaeidae(eg. some Metabelbaspecies). I did not find differences in leg setation formula; nevertheless, dorsal setae of the femora are much stronger than other setae, covered by distinct spinuli (Fig. 5). The most characteristic synapomorphy of Porobelba- single area porosa on posterior part of notogaster - is absent. This observation was confirmed by Norton (pers. comm.), who studied quite extensive American material. The most typical character of the species is very long sensillus, slightly but distinctly broadened (lanceolate) towards the end.  FIGURE 4. Porobelba spinosa (Sellnick): A -prodorsum and anterior part of notogaster, C -sensillus and bothridial complex; Porobelba parki Jacot: B -prodorsum and anterior part of notogaster, D -sensillus and bothridial complex. Abbreviations: P -propodolateral apophysis; for the rest see Fig. 1 and Fig. 3 It is clear that P. parkidoes not share characters of Porobelbaas given in the diagnosis above. Differences are quite numerous even if general appearance and some characters are similar (size, legs and their setation). Some of the differences observed have been commonly used for establishing genus-level taxa within Damaeidae. The generic or specific value of leg setae characters and shape of the sensillus is unclear, but the presence of apophysis P, shape of parastigmatic apophyses and position of notogastral setae in two parallel rows are collectively of generic significance. Therefore, a new genus, closely related to Porobelbawill be proposed in the subsequent paper of this series, together with a detailed redescription of P. parki. 923904552 Appalachian Mountains SMF A.
