Corunastylis tecta is a tuberous herb. It has fairly small flowers forming an uncrowded spike 4-5cm long with only a few flowers open at once. The flowers are reddish with a dark reddish-black labellum (Jones 1991b).

This species is known only from the vicinity of Sunday Ck S of Cardwell, NE Qld (Jones 1991b) and is known to occur in a national park (D.L.Jones 2002, pers. comm.).

A morphological examination of the Genoplesium group showed that Genoplesium is monotypic (represented by a single species) and that Corunastylis should be recognised for the majority of species in the group (Jones et al. 2002).

Corunastylis tecta (previously known as Genoplesium tectum) is a distinctive species with no obvious relationships to any other member of the genus. It can be recognised by its tall slender habit, small flowers widely spaced on the spike, the relatively small elliptical labellum sparsely fringed with short cilia, and the distinctive long acuminate column wing. Its habitat is also distinctive (Jones 1991b).

This species occurs in dense scrub not far from a creek (D.L.Jones 2002, pers. comm.) among dense sedges and low shrubs in woodland dominated by Melaleuca viridiflora (Dockrill 1969). Soils are seasonally inundated sandy loams (Jones 1991b).

Flowering occurs from Nov. to Mar. and reproduction is entirely by seed (Jones 1991b). The species is a deciduous terrestrial orchid with a single leaf and grows as an individual or in small loose groups. A single tuber is produced annually from that of the previous season (Jones 1991b).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
