Suctobelba regia is distributed throughout Europe. It is characteristic of acidic forest soils. This species was first found in Norway in 2019. It occurred in a broadleaf forest in nearly all habitats studied and was quite abundant. The species is parthenogenetic, only females are present and they are produced from unfertilized eggs.
Adult: The body length is 247–279 µm, and width is 131–159 µm. The color is light to dark brown. As in all Suctobelba the front edge of notogaster has a thickening near each bothridium. In the front of prodorsum, in the middle, there are large lobular tubercles, arranged in three longitudinal rows (marked by arrowhead in Fig. 1). Lateral to these rows there are mesh-like cuticular stripes. Notogaster has S-shaped setae.
Juvenile stages: unknown.
Suctobelba regia resembles S. trigona (Michael, 1888) (that is more often found in forests), but differs from it by the pattern on the prodorsum (lobular tubercles arranged in three longitudinal rows, and lateral to them mesh-like cuticular stripes). Suctobelba trigona has prodorsum without nodes and there are only 2–3 transverse lines in the front of prodorsum (Fig. 2).
The reproduction is parthenogenetic, only females are present and they are produced from unfertilized eggs. The development and feeding preferences of S. regia are unknown.
Suctobelba regia is distributed throghout Europe.

Findings in Norway
Suctobelba regia was first found in Norway in 2019. It occured in a low-herb broadleaf forest in Kvam, Western Norway. The species was found in nearly all habitats studied (moss on dead wood, ground, on tree trunks and stumps), except of dead wood. In total over hundred adult specimens were found, among over 6300 oribatid specimens studied. It seemed to prefer mosses growing on tree bark and on dead wood.
