Firth's Midge-orchid is a deciduous terrestrial herb (D.L.Jones 2001, pers. comm.) growing to 10 cm tall with small flowers (Jones 1998d).

This species is endemic to eastern Tas. (Jones 1998d). It is only known from two coastal localities at Coles Bay and nearby Friendly Beaches on the central east coast (Jones et al. 1999).

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).

G. firthii was treated as a synonym of G. brachystachyum (Jones & Clements 1989), but further studies show that the two are distinct. G. firthii is characterised by small stature (to 10 cm tall); few-flowered (one to six) inflorescence; small flowers (dorsal sepal to 3 mm long; lateral sepals to 4 mm long); labellum oblong to oblong-obovate, thin-textured; column wings deeply divided (Jones 1998d).

This species grows in low coastal scrub and tall open banksia shrubland with a heathy and sedgy understorey, on a well-drained rise in sand derived from granite, at altitudes between 0-20 m (Jones 1998d; A. Moscal, pers. comm. in Jones et al. 1999).

Flowering occurs from Dec. to Mar. (Jones 1998d). This species reproduces solely from seed (D.L.Jones 2001, pers. comm.).

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.
