76BB6CB235B15DDB842D13C67C3AD11E.taxon	diagnosis	Diagnosis. Telipogon rojasiae is most similar to Telipogon montufarianus but differs by its cream-yellow flowers heavily stained with red vinaceous (vs. bright yellow flowers), the sub-rhombic to obovate petals, 15 – 17 × 11 – 12 mm (vs. elliptic petals, 12 × 8 mm), the greater number of veins in the petals (9 – 10 veins vs. 5 veins) and labellum (26 veins vs. 16 – 19 veins), and its sagittate callus (vs. a widely sub-cordiform callus).	en	Martel, Carlos, Diaz Hernández, Alex G., Iturralde, Gabriel A., Collantes, Benjamín (2025): Telipogon rojasiae (Orchidaceae, Oncidiinae), a new species from relict forests on the western slopes of the northern Peruvian Andes.

76BB6CB235B15DDB842D13C67C3AD11E.taxon	description	Description. Epiphytic herb, erect, sympodial, acaulous in young plants and with a visible short stem in older plants, up to 15 cm including the inflorescence. Roots terete, 1.6 – 2.2 mm in diameter. Stem abbreviated, forming pseudobulb-like structures on mature plants. Leaves 2.5 – 5.9 × 0.6 – 1.1 cm, 3 – 9, subcoriaceous, lanceolate-oblong to narrowly sub-elliptic, entire, acute apex, base articulated to a conduplicate leaf sheath that covers the stem; the basal leaves smaller than the upper leaves. Inflorescence an apical and lateral raceme; scape 5 – 7 × 0.2 cm, triquetrous, up to 5 flowers, one to two flowers opening in succession. Floral bract 15 – 16 × 5 – 6 mm (progressively decreasing in size in the following bracts), conduplicate, decurrent, falcate in natural position, widely ovate when expanded, acute, carinate. Ovary 20 – 21 × 3.0 – 3.1 mm, triquetrous, winged, pedicellate. Pedicel 6 – 11 mm long, triquetrous. Flowers 20 – 25 mm in diameter, non-resupinate. Sepals greenish-yellow with red vinaceous, spots, semitranslucent; lateral sepals 11 – 12 × 5 – 6 mm, ovate, entire, basally concave, acute apex, curved in natural position, with entire margin, 3 - veined, carinate abaxially; dorsal sepal 13 – 14 × 5 – 6 mm, narrowly ovate, entire, concave towards the base, acute apex, 3 - veined, carinate abaxially. Petals 15 – 17 × 11 – 12 mm, red-vinaceous with spots, sub-rhombic to obovate, apex acute to sub-acute, 9 – 10 - veined. Labellum 12 – 13 × 16 – 17 mm when expanded, red-vinaceous with spots, reniform, concave, the base embracing almost the entire column, the apex rounded, protruding, 26 - veined. Callus 3.2 – 3.6 × 5.7 – 6.1 mm, elevated, dark purple towards the apex, yellow towards the base, sagittate with a rounded apex, setose at the centre of the apex, fimbriate margin. Column 3.4 mm long, 2.4 mm wide, sub-rhomboid, dark yellow, ventral surface densely covered by minute conical papillae with acute apex, 3 tufts of setae; setae dark purple to white, simple, capilliform, up to 2.2 mm long. Clinandrium concave, with rounded edges, with a dorsal projection covering up to half of the anther cap. Stigma suborbicular. Rostellum erect. Anther cap 1.7 × 2.1 mm, red, cordiform, bilocular. Pollinarium 2.4 × 1.9 mm; pollinia 4 in 2 unequal pairs; outer pair obovoid, convex-flat; inner pair ellipsoid, laterally complanate; caudicle hyaline; viscidium uncinate. Fruit not seen.	en	Martel, Carlos, Diaz Hernández, Alex G., Iturralde, Gabriel A., Collantes, Benjamín (2025): Telipogon rojasiae (Orchidaceae, Oncidiinae), a new species from relict forests on the western slopes of the northern Peruvian Andes.

76BB6CB235B15DDB842D13C67C3AD11E.taxon	distribution	Distribution, habitat and ecology. Telipogon rojasiae is only known from the western slopes of the northern Peruvian Andes between 2800 and 3400 m asl (Fig. 4). The ecosystem of this area has been categorised as relict montane forests of the western slope (Ministerio del Ambiente 2019). These relict forests are located in the western Andean slopes of northwest Peru and southwest Ecuador and possess a rich biodiversity, including many endemic species and genera (Weigend et al. 2005 a, 2005 b). We have so far recorded five small subpopulations, which occur in small forest patches. In these areas, Miconia sp. is the dominant plant species, followed by Brachyotum ledifolium (Desr.) Triana, Hedyosmum scabrum (Ruiz & Pav.) Solms, Grosvenoria jelskii (Hieron.) R. M. King & H. Rob., and Myrica pubescens Humb. & Bonpl. ex Willd. In terms of orchids, many species co-occur with T. rojasiae, including Cyrtochilum loesenerianum (Schltr.) Dalström, Epidendrum capitellatum C. Schweinf., E. hemiscleria Rchb. f., E. scutella Lindl., Fernandezia ionanthera (Rchb. f. & Warsz.) Schltr., Liparis elegantula Kraenzl., and Telipogon papilio Rchb. f. & Warsz. The flower morphology resembles the general morphology of flowers in Telipogon species pollinated by sexual deception involving tachinid male flies (e. g. T. peruvianus T. Hashim., T. bowmanii Rchb. f.; Martel et al. 2016, 2019), which suggests T. rojasiae may have a similar pollination mechanism.	en	Martel, Carlos, Diaz Hernández, Alex G., Iturralde, Gabriel A., Collantes, Benjamín (2025): Telipogon rojasiae (Orchidaceae, Oncidiinae), a new species from relict forests on the western slopes of the northern Peruvian Andes.
