Abstract

THOERLE, Lisa  and  MEDINA TREJO, Ramiro. Diodonopsis Ramiromedinae (Orchidaceae: Pleurothallidinae), a new species from Colombia. Lankesteriana [online]. 2017, vol.17, n.2, pp.223-226. ISSN 1409-3871.  http://dx.doi.org/10.15517/lank.v17i2.30077.

A new species, Diodonopsis ramiromedinae, is described, illustrated, and compared with similar species. A brief history of Masdevallia sect. Pygmaeae and the genus Diodonopsis is provided. Diodonopsis ramiromedinae is most similar to D. anachaeta, but differs by sepals with apices acute or acuminate-triangular vs. narrowly caudate; longer petals with a descending, narrowly linear, rounded basal process vs. with an acute, retrorse basal process; and the larger lip, obovate with the apex very broadly rounded vs. oblong-subpandurate with the apex acute.

Keywords : Colombia; Diodonopsis; Masdevallia; new species; Pleurothallidinae; section Pygmaeae.
