Description of Nebela:
Test: ovate, pyriform, elongate or with a long neck, always compressed sometimes with lateral pores. Yellowish, transparent often with predated siliceous plates or diatom frustles in an unstructured organic cement. Ovular nucleus. Most Nebela sp. are predators of small Euglyphida. Habitat: common in mosses (sphagnum) and soil. Loeblich & Tappan (1964) have designated Nebela numata Leidy, 1874 as valid type species which unfortunately is a junior subjective synonym of Nebela collaris (Ehrenberg, 1848).
