Trichotosia gabriel-asemiana Mambrasar & Schuit., spec. nov.
Diagnosis. This species is similar to Trichotosia microphylla Blume and T. dalatensis by its slender, creeping rhizome, short leaves (less than 2 cm long), and solitary flowers with an abaxial, conical callus near the lip apex. Trichotosia dalatensis has flowers that are similar in size and in the maroon colour, but differs in having a glabrous, uniformly thick lip with a distinct adaxial callus, whereas T. gabriel-asemiana has a lip that is sparsely pilose abaxially and which is abruptly divided into a fleshy basal part and a thin textured upper part, but lacks an adaxial callus. Trichotosia microphylla has larger, yellowish green flowers (lip ca. 9 mm long, vs. 4 mm in T. gabriel-asemiana), with the lip not pubescent abaxially, and not abruptly divided into a fleshy basal part and a thinner upper part.
Etymology. Named in honour of Gabriel Asem, Regent of Tambrauw Regency since 2011, who in 2015 declared Tambrauw regency a conservation zone.
