Mahunka, S.: Some oribatid mites from Yemen (Acari: Oribatida) (Acarologica Genavensia LXXXVIII)

Notogaster: Dorsosejugal suture strongly arching anteriorly. Notogastral surface ornamented by irregular, hardly observable wrinkles. Fourteen pairs of notogastral setae equal in length and size present, all well barbed. Among the porose areac Athe largest, the other three pairs nearly equal in size. Lateral part of podosoma (Fig. 21): Tutorium well discernible. Sublamellar porose area indistinct. Circumpedal carina very strong and thick connected with the lateral minitectum, which is clearly visible longitudinally. Ventral regions (Fig. 20): Anterior part of epimeral region sligthly polygonate, other surface well foveolate. This sculpture visible also on the anal plates. Epimeral setae conspicuously short but well ciliate. Remarks - The new species is well characterised by the peculiar sculpture of the notogaster, the ratio of the porose areae but mainly by the very strong, unique circumpedal carina. Etymology - The species is named after the collecting site, City of Mabar. Zygoribatula socotrensis sp. n. (Figs 22-24) Material examined - Holotype: S 47, 1 paratype from the same sample. Holotype: MHNG, paratype (1544-PO-1996): HNHM. Description - Measurements: Length of body: 416-442 pm, width of body: 276-297 pm. Prodorsum: Rostrum widely rounded. Lamellae and translamella well developed, wide. Distal end of lamellae and translamella highly protruding from the notogastral surface, lamellar setae arising from this anterior margin. Rostral, lamellar and interlamellar setae distinctly barbed. Notogaster: Surface with very fine, indistinct sculpture, it consists of irregular small rugae. Some stronger, longitudinal wrinkles observable in the humeral region. All fourteen pairs of notogastral setae nearly equal in length and size. Porose areae small, nearly round, no essential difference among them (Fig. 22). Lateral part of podosoma (Fig. 24): Tutorium hardly observable, indistinct. Sublamellar porose area absent. Circumpedal carina very strong, thick, it runs to the mental tectum anteriorly reaching to the lateral margin of the ventral plate. Ventral regions (Fig. 23): Epimeral region sparsely foveolate, ventral plate densely foveolate, trough foveolae fine and indistinct, sometimes hardly observable. Epimeral setae and the setae on the ventral, genital and aggenital plates nearly equal in length, genital and anal plates smooth. Remarks - The new species is well characterised by the peculiar sculpture of the notogaster, the equally small and round porose areae and by the very thick and long circumpedal carina. On the basis of these main features the new species is well distinguishable from all its congeners. Etymology - The species is named after the Socotra Island.
