Lepanthopsis hyalina (H.Stenzel) Karremans , comb. nov.

Bas. Platystele hyalina H.Stenzel, Willdenowia 32: 103. 2002.

When describing Platystele hyalinia, Stenzel (2002) recognized that the species had intermediate features between Platystele and Lepanthopsis , but chose to place it in the first because of the glabrous sheaths on the ramicaul. However, the sheaths are ribbed and thickened like those of any other Lepanthopsis . Also consistent with Lepanthopsis are the multiple racemes per ramicaul, several simultaneous flowers, very short petals, bilobed stigma and elongated pollinia.

Scaphosepalum Pfitzer, Nat. Pflanzenfam. 2(6): 136, 139. 1889[1888]. Type: Masdevallia ochthodes Rchb.f., Bonplandia 3: 70. 1855.

Scaphosepalum as defined by Luer (1988), Pridgeon (2005) and Endara (2011) is retained. We are able to account for 52 species in the genus, with a distribution from Costa Rica to Bolivia and the Guyana Shield, and the highest diversity in the northern Andes of Colombia and Ecuador. They are distinguished especially by the non-resupinate flowers and the lateral sepals forming a basally concave synsepal and that are apically narrowed and thickened, usually with thickened calli on the distal portion.

Teagueia (Luer) Luer, Monogr. Syst. Bot. Missouri Bot. Gard. 39: 140. 1991. Bas. Platystele subgen. Teagueia Luer, Monogr. Syst. Bot. Missouri Bot. Gard. 15: 45. 1986. Type: Platystele teagueia Luer, Selbyana 5: 157. 1979.

Teagueia as defined by Luer (1991a) and Pridgeon (2005) is retained. We are able to account for 14 species in the genus, all endemic to Colombia and Ecuador. They are distinguished by the long-tailed sepals, the inconspicuous petals, the ovoid to suborbicular lips, with a deeply cleft disc, the short column with an apical anther and stigma.
