Oribatula longelamellata Schweizer, 1956


Oribatula longelamellata Schweizer, 1956 

( Figure 4View FIGURE)

Literature — Schweizer (1956), Grobler and Skubala (2000), Weigmann (2006).

Material examined — 2 specimens from the Retezat Massif, 1 specimen from Turu’s Gorges (Apuseni Mountains)  .

Diagnosis — Medium sized species, one of the smaller representatives of the genus (Table 1), light yellowish in colour. Cuticle smooth, without ornamentation. Prodorsum elongated, with long lamellae; lamellar apex with a rounded, evident cuspis. A long prolamella is present, almost reaching the origin of rostral setae ( Figure 4bView FIGURE). Prodorsal setae finely barbed, sensillus fusiform clavate. Notogaster oval, rounded, with 13 pairs of simple and short setae ( Table 2). Areae porosae are small, round, in the usual position. Epimeral and genito-anal regions with typical aspect. Chaetotaxy of these regions are also characteristic for the genus.

Distribution and autecology — Central and Western Europe ( Subias 2004). O. longelamellata  is a mountain to alpine species; in Romania was recorded in the Retezat National Park and in the Turu’s Gorges (Apuseni Mountains), only on limestones, therefore can be considered a stenotopic form ( Vasiliu et al. 1993).
