Pleurothallis austrorientalis is known from the eastern slope of the southern Ecuadorian Andes, forming part of the ecosystem known as evergreen montane forest at the south of the Cordillera Oriental of the Andes (BsMn 02) (Ministerio de Ambiente del Ecuador 2013), between 2400 and 2700 m in elevation. This region corresponds to the southern Ecuadorian provinces of Azuay, Loja, and Zamora-Chinchipe (Fig. 8), which is known as a biological ‘ hotspot’ due to its extraordinarily high diversity and endemism levels (Quizhpe et al. 2002; Tapia-Armijos et al. 2015). This area is the weather divide between the humid Amazon (“ Oriente ”) and the dry Inter-Andean region, and it is the transition zone between the perhumid montane broad-leaved forest and the upper montane forests (Beck et al. 2018).</p><p>Individuals of this species grow as epiphytes close to the ground in the understory over ravines. The flowering of this species occurs between February and May. It grows together with other orchid species such as Cyrtochilum funis (F. Lehm. &amp; Kraenzl.) Kraenzl., Masdevallia mandarina (Luer &amp; R. Escobar) Luer, M. norops Luer &amp; Andreetta, Maxillaria hastulata Lindl., Pleurothallis bivalvis Lindl. and P. omoglossa Luer.</p><p>Conservation assessment.</p><p>The species is known from four occurrences representing four localities: Zamora-Chinchipe Province (holotype near El Tambo), one record near Estación Científica San Francisco, approximately 3 km to the south, one near Cajanuma (approximately 20 km to the south), and Azuay Province (near Jima, approximately 85 km to the north). The calculated extent of occurrence (EOO) of Pleurothallis austrorientalis is 430 km 2, and the area of occupancy (AOO) is 16 km 2.</p><p>Studies have documented a pronounced trend of habitat loss and fragmentation in the southeastern provinces of Ecuador. Tapia-Armijos et al. (2015) reported that between 1976 and 2008, the region experienced annual deforestation rates ranging from 0.75 % to 2.86 %, accompanied by a drastic reduction in the average size of forest fragments and increased isolation. Approximately 46 % of the original forest has been converted into landscapes dominated by agricultural activities, compromising ecological connectivity and ecosystem resilience. This fragmentation is not restricted to unprotected areas; even within the National System of Protected Areas (SNAP) and protective forests, patterns of forest cover loss and declining structural and functional connectivity have been observed (Kleemann et al. 2022; Noh et al. 2022). The expansion of pastures and crops remains the main driver of fragmentation in Andean and Amazonian ecosystems, compounded by external pressures such as road construction and mining (Mestanza-Ramón et al. 2022; Mena-Quintana et al. 2025).</p><p>Given the restricted known distribution (EOO &lt;5,000 km 2; AOO &lt;500 km 2; ≤ 5 locations) and the documented habitat degradation, we recommend assessing Pleurothallis austrorientalis as Endangered (EN) under criteria B 1 ab (iii) + 2 ab (iii).</p><p>Additional specimens examined.</p><p>Ecuador • Azuay: Near Jima, cultivated by Linder Suin, 6 Mar 2001, C.

The former occurs in central Peru. The differences between P. austrorientalis and P. crateriformis were outlined in the diagnosis; however, additional distinctions are noted here. The new species has previously been confused with P. crateriformis . Luer (2005), in his monograph on Acronia C. Presl section Macrophyllae-Fasciculatae, illustrated the species and misidentified it as Acronia crateriformis (Fig. 10). Pleurothallis austrorientalis is distinguished from P. crateriformis by its concave-subplicate leaves attenuate at the apex (vs. plane, acute), the adaxial surface of the flowers covered with chocolate-colored papillae (vs. yellow), linear-falcate petals with revolute margins (vs. lanceolate-linear, flat), a broadly obovate, crateriform, subacute synsepal, 7.2–7.9 mm wide (vs. navicular, oblong-ovate, obtuse, 4.2 mm wide), a saccate lip (vs. navicular-saccate), and a whitish yellow anther (vs. purple).</p><p>From Pleurothallis pyelophera, the new species is distinguished by its larger, attenuate leaves, 7.2–10.3 cm long (vs. 5.5–7.0 cm long, acute), a subverrucose, subterete ovary (vs. densely, minutely papillose, obconic), uniformly colored flowers (vs. striped), an elliptic-ovate, 5 - veined dorsal sepal (vs. 7–8 - veined, subcircular), a bowl-shaped synsepal (vs. navicular), linear-falcate, 1 - veined petals with revolute margins (vs. 2 - veined, oblong, margins flat), a lip that is elliptic-saccate with a narrowly elliptic cavity (vs. thickly navicular with a narrowly ovate cavity), obtuse basal angles (vs. triangular), a rounded apex (vs. obtuse), and the reniform stigmatic cavity (vs. trapeziform).</p></div>	https://treatment.plazi.org/id/E9C6D8CCEF0A5020B97E99B1D25EF92C	Public Domain	No known copyright restrictions apply.

In the type locality, individuals of this species grow as epiphytes close to the ground in the understory. Other species of orchids, such as Elleanthus conifer (Rchb. f. &amp; Warsz.) Rchb. f., E. virgatus (Rchb. f.) C. Schweinf., Masdevallia lilacina Königer, M. mendozae Luer, Maxillaria pachyacron Schltr., and Oncidium gayi J. M. H. Shaw, were found sympatrically with P. monteroae . In this area, the local flora is dominated by Baccharis genistelloides (Lam.) Pers., Clusia multiflora Kunth, Semiramisia speciosa (Benth.) Klotzsch, Symbolanthus jasonii J. E. Molina &amp; Struwe and Siphocampylus scandens (Kunth) G. Don. A second locality was found north of the type locality near Tundayme by Raquel Betancourt in 2018 (Figs 7 B, 8). The flowering of this species occurs between March and November.</p><p>Conservation assessment.</p><p>The species is currently known from four occurrences in two localities in Zamora-Chinchipe Province: three near Cerro Plateado (holotype + two iNaturalist photographic records) and one near Tundayme, ca. 100 km to the north (georeferenced photographic record). The calculated extent of occurrence (EOO) based on these records is 98 km 2, and the area of occupancy (AOO) is 16 km 2.</p><p>The known localities are all within an area heavily impacted by large-scale mining concessions, which have already caused severe deforestation and habitat fragmentation in the Cordillera del Cóndor region (Mestanza-Ramón et al. 2022; Mena-Quintana et al. 2025). These threats are ongoing and directly affect habitats required by orchids. Although some populations occur near government-protected areas, such as Cerro Plateado and El Quimi Biological Reserves and El Zarza Wildlife Refuge, these areas do not guarantee effective conservation. Mining concessions overlap with legally protected zones (Roy et al. 2018; Peck et al. 2024), undermining their integrity and exposing the species to severe threats. The proximity of mining concessions to all known localities of Pleurothallis monteroae significantly increases the risk of population decline and potential extinction. Even within protected areas, the presence of concessions indicates weak enforcement of conservation policies.</p><p>Although the species may be more widespread but under-collected in southeastern Ecuador, the extremely restricted known distribution (EOO &lt;5,000 km 2; AOO &lt;500 km 2; ≤ 5 locations), combined with the high level of threat and an inferred continuing decline in habitat quality, justifies a preliminary assessment of Endangered (EN) under criteria B 1 ab (iii) + 2 ab (iii), following the precautionary principle recommended by the IUCN.</p><p>Additional records.</p><p>Ecuador • Zamora-Chinchipe: Nangaritza, 24 April 2024, observation in iNaturalist by Paola Ordóñez Montero, https://www.inaturalist.org/observations/209190380 (Suppl. material 1) ; Nangaritza, 18 March 2025, observation in iNaturalist by Paola Ordóñez Montero, https://www.inaturalist.org/observations/265967102 (accessed 25 Aug 2025) ; near Tundayme, 2 November 2018, photo by Raquel Betancourt privately shared with M. Jiménez (reproduced in Fig. 7 B) .</p><p>Taxonomic notes.</p><p>Pleurothallis monteroae is most similar to P. phymatodea in its similarly sized plants (less than 10 cm tall), thickly coriaceous, convex leaves, a suborbicular dorsal sepal, and an ovate, bowl-shaped lip. The new species is distinguished from P. phymatodea by its pale yellow ovary and flowers covered with chocolate to purple papillae (vs. purple-black flowers and ovary with verrucae of the same color), petals with flat margins (vs. involute), and a transversely elliptic synsepal (vs. transversely ovate). Another difference between the two species is the transversely elliptic stigma in the new species (vs. broadly hexagonal in P. phymatodea; Fig. 4 A). P. monteroae is the only species in the group known to have a glenion inside the cavity of the lip.</p><p>Pleurothallis monteroae also shows affinities with P. equipedites in its yellowish flowers with purple pustules. However, the new species differs in its smaller dorsal sepal, 5.0–5.3 × 3.9–4.5 mm, and synsepal, 4.3–4.6 × 3.8–4.5 mm (vs. 6.0–7.2 × 5.1–6.0 mm and ca. 6.7 × 6.6 mm, respectively). The most distinctive difference lies in the lip, which in P. monteroae is cordiform-ovate and crateriform, with a T-shaped cavity and a unique bilobed glenion surrounded by two rounded calli (vs. calceiform, with a lanceolate, canaliculate cavity and two elongated, ribbed calli).</p></div>	https://treatment.plazi.org/id/F51289550660501C9B11B30B5FAAFC7C	Public Domain	No known copyright restrictions apply.
