038887E1FFC4FF8E9AACF919FE296D6D.taxon	materials_examined	Type: — MEXICO. Chiapas: Berriozábal, ca. km 16 del camino Berriozabal-El Cairo, selva del Ocote, ca. 1050 m, selva baja perennifolia achaparrada, ventosa, collected at 17 abril 1989, dryed at 18 Febrero 1989, M. Soto & E. Martínez 5405 (holotype: AMO!). Taxonomic discussion: — Lepanthes ernestii is recognized by its ovate leaves, almost as long as the stem, raceme shorter than the leaf, ovate and shortly apiculate sepals, strongly bilobed petals, with quadrangular and rounded lobes, the upper one larger, lanceolate and falcate blades of the lip, and a mammilated, pubescent, yellowish appendix (Figures 1 – 3). Initially, this taxon was considered a form of Lepanthes acuminata with subspecific rank, geographically isolated in northern Chiapas (Salazar & Soto 1996). However, the discovery of morphologically similar individuals in Chiapas, Veracruz, and Guatemala, indicates that this taxon is not a subspecies, but a species represented by several populations with a wider distribution than originally thought. Lepanthes acuminata (Figure 4) differs in its larger habit (10 – 12 cm tall vs. up to 5.0 cm tall), stems longer than the leaf (vs. as long as the leaf), larger flowers (10.0 – 11.0 mm tall vs. 7.0 - 8.0 mm tall), lanceolate and long attenuate-acuminate sepals (vs. ovate and acute), petals barely bilobed with similar lobes (vs. prominently bilobed with lobes different in size), and an appendix incurved (parallel and folded against the lip’s connectives vs. perpendicular in relation to the connectives).	en	Solano, Rodolfo, Licona, Ethian, Carral, Rodrigo, Téllez-Baños, Bruno (2025): Two new species, nomenclatural notes and an updated checklist in Lepanthes (Orchidaceae, Pleurothallidinae) from Mexico.

038887E1FFC4FF8E9AACF919FE296D6D.taxon	distribution	Distribution and ecology: — Mexico (Chiapas, Oaxaca, Veracruz), Guatemala (Alta Verapaz). The first records of this taxon in the flora of the states of Oaxaca and Veracruz (Mexico), as well as that of Guatemala, are documented here. The best distribution model for L. ernestii had an AUC = 0.902, where Bio _ 10 (Mean Temperature of Warmest Quarter) was the most contributing variable with 65.7 %, followed by Bio _ 14 (Precipitation of Driest Month) with 27.2. %, and Bio _ 5 (Max Temperature of Warmest Month) with 6.6 %. The MaxEnt Jackknife test showed that Bio _ 5 (Max Temperature of Warmest Month) was the most contributing variable when used in isolation, thus providing the most useful information. Meanwhile, Bio _ 14 (Precipitation of Driest Month) was the variable that, when omitted, caused the greatest reduction in contribution, suggesting it provides unique information absent in the other variables. The model predicts four zones with high probability for the distribution of L. ernestii: the southern portion of Sierra Madre Oriental, Sierras of northern Oaxaca, Altos of Chiapas, and the Sierra Los Cuchumatanes (Guatemala) along with the southern portion of the Sierra Madre of Chiapas (Figure 5). The adjusted model had a cutoff value of 0.397, generating a potential occupancy area of 103,337.56 km 2, of which 76,865.13 km 2 are in Mexico (3.91 % of its territory) and 26,472.43 km 2 in Guatemala (24.31 % of its territory). Lepanthes ernestii grows as an epiphyte on Quercus trunks, in the cloud forest, ranging between 1050 – 1460 m elev. Until recently, this taxon was thought to be restricted to the Central Plateau of Chiapas. However, the records presented here expand its distribution area to the neighboring states of Oaxaca and Veracruz, as well as to Guatemala. Flowers from April to June. Conservation status: — Not evaluated by the IUCN Red List or the Extinction Risk Evaluation Method for Mexican wild flora species (SEMARNAT 2019). Additional field studies are required to assess the viability of its populations and the quality of its habitat. In Mexico, L. ernestii is known from four disjunct localities (except those found in Veracruz), with a potential distribution covering 3.91 % of the country’s surface area. In Veracruz, the population of this species is within a protected area, the Cofre de Perote National Park, where favorable habitat still exists for it. The populations in Chiapas and Oaxaca persist in remnant forests, close to human settlements, and face anthropogenic effects such as the expansion of urban areas, opening of lands for agriculture, or extraction of wood and firewood.	en	Solano, Rodolfo, Licona, Ethian, Carral, Rodrigo, Téllez-Baños, Bruno (2025): Two new species, nomenclatural notes and an updated checklist in Lepanthes (Orchidaceae, Pleurothallidinae) from Mexico.

038887E1FFC4FF8E9AACF919FE296D6D.taxon	distribution	Distribution and ecology: — Endemic to Mexico, in Oaxaca. The best distribution model for L. luicitae had an AUC = 0.975, where Bio _ 8 (Mean Temperature of Wettest Quarter) was the most contributing variable with 42.4 %, followed by Bio _ 3 (Isothermality) with 22.3 %, and Bio _ 15 (Precipitation Seasonality) with 19.2 %. The MaxEnt Jackknife test showed that Bio _ 5 (Max Temperature of the Warmest Month) was the most contributing variable when used in isolation, thus providing the most useful information. On the other hand, Bio _ 3 (Isothermality) was the variable that, when omitted, caused the greatest reduction in contribution, suggesting it provides unique information absent in the other variables. The model predicts a single region with high probability for the distribution of L. luicitae, which would be a micro-endemism restricted to Sierras of northern Oaxaca (Figure 8). The adjusted model had a cutoff value of 0.286 and generated a potential occupancy area of 4,013.10 km 2, which corresponds to 0.20 % of the Mexican territory. Lepanthes luicitae ranges between 1850 – 2400 m, where it grows as an epiphyte on small to medium tree trunks, in shaded, humid, and well-ventilated sites within the cloud forest (Figure 7). The climate is semi-warm humid, with average annual temperature of 18 º – 20 º C, and an annual precipitation higher than 1700 mm, much of it in the form of fog, which is frequent throughout the year. It has been seen flowering from November to April.	en	Solano, Rodolfo, Licona, Ethian, Carral, Rodrigo, Téllez-Baños, Bruno (2025): Two new species, nomenclatural notes and an updated checklist in Lepanthes (Orchidaceae, Pleurothallidinae) from Mexico.

038887E1FFC4FF8E9AACF919FE296D6D.taxon	description	Taxonomic discussion: — Lepanthes luicitae is distinguished by its elliptical leaves, a raceme progressively elongating when new flowers are produced to be longer than the leaf, ovate, ciliated sepals, with the lateral ones diverging each other at their apices, narrowly lanceolate blades of the lip, and an oblong and pubescent appendix (Figures 6 – 7). The more similar species is Lepanthes thurstoniorum (Figure 9 A), which becomes sympatric in some localities. However, it differs by its zigzag rachis (vs. flexuous rachis), lateral sepals almost 2 / 3 the width of the dorsal one (vs. dorsal sepal as wide as the lateral ones), lateral sepals obliquely triangular-ovate and subparallel to each other towards their apices (vs. obliquely ovate and diverging from each other towards their apices), and petals forming oblong and oblique blades (vs. forming butterfly wing-like blades).	en	Solano, Rodolfo, Licona, Ethian, Carral, Rodrigo, Téllez-Baños, Bruno (2025): Two new species, nomenclatural notes and an updated checklist in Lepanthes (Orchidaceae, Pleurothallidinae) from Mexico.

038887E1FFC4FF8E9AACF919FE296D6D.taxon	description	Lepanthes schiedei is somewhat similar too (Figure 9 D), but it differs by its narrower flowers (2.0 – 2.5 mm in wide vs. 55.5 mm in wide), triangular-lanceolate not ciliate sepals (vs. ovate and ciliate), oblong lobes of the petals (vs. triangular), the upper ones overlapping at their apices (vs. non-overlapping), and lanceolate blades of the lip (vs. narrowly lanceolate). Conservation status. Not evaluated by the IUCN Red List nor the Extinction Risk Evaluation Method for Mexican wild flora species (SEMARNAT 2019). Additional field studies are required to assess the viability of its populations and the quality of its habitat. So far, the species is known from five very close localities in a restricted region, with a potential distribution covering 0.20 % of the country’s surface area. These localities occur within or near natural protected areas by local communities in Oaxaca, where the forest has a management program compatible with the conservation. However, beyond these areas, the forest is being altered by agricultural practices of itinerant or permanent crops (Pérez-García & del Castillo-Sánchez 2016, 2017). The increase in human settlements and the border effects associated with the aperture of new roads in the region is an additional risk for the species. Plants of Lepanthes luicitae grow in the richest Mexican region for Lepanthes, the northern highlands of Oaxaca. So far, 27 species have been recorded, representing 39.7 % of the genus’s richness in Mexico.

Lepanthes machorroi is distinguished among the species of the genus in Mexico by its white flowers, abruptly acuminate-caudate and ciliate sepals, symmetric, apiculate, and papillose petals, oblong laminae of the lip, emarginate at the apex, with sharp margins, and prominently papillose, connectives of the lip with a hemispheric ventral projection, and a filiform and glabrous appendix (Figure 10). This species was previously only known from three localities in Northern Highlands of Oaxaca, Mexico (Salazar & Soto 1996).

On the other hand, Bio _ 4 (Temperature Seasonality) was the variable that, when omitted, caused the greatest reduction in contribution, suggesting it provides unique information absent in the other variables. The model predicts two areas with a high probability for the distribution of L. machorroi, one in the southern part of the Sierra Madre Oriental and the other in Sierras of northern Oaxaca (Figure 11). The adjusted model had a cutoff value of 0.301 and generated a potential occupancy area of 10,198.23 km 2, which corresponds to 0.52 % of the Mexican territory. Lepanthes machorroi grows as an epiphyte in the cloud forest, ranging between 2000 – 2250 m elev. In Veracruz the species was found growing on Quercus delgadoana Valencia, Nixon & Kelly (2001: 275), together with Lepanthes avis, L. calopetala Salazar & Soto (1996: 77), L. salvaterrae, and L. totontepecensis Salazar & Soto (1996: 206). It flowers between June and November. Conservation status: — Not evaluated by the IUCN Red List or the Extinction Risk Evaluation Method for Mexican wild flora species (SEMARNAT 2019). Additional field studies are required to assess the viability of its populations and the quality of its habitat. The species is known from five localities, one in Veracruz and four more in Oaxaca, which are very close to each other, with a potential distribution covering 0.52 % of the country’s surface area. In Veracruz, the known populations of this species are within a protected area. the Salvaterra Ecological Reserve. It is also very close to the Cofre de Perote National Park, which could provide additional favorable habitat. The localities in Oaxaca occur within or near natural protected areas by local communities, where the forest has a management program compatible with the conservation.

Greenwood (holotype: AMO!, isotype: AMO [in spirit]!). Lepanthes papilionacea is distinguished from its congeners by its sepals with long, rigid, and spaced-out cilia, ascending on the dorsal sepal and descending on the lateral ones, with some cilia along the veins on the abaxial surface; the petals are strongly bilobed, with highly dissimilar lobes; the appendix of the lip is formed by a triangular, glabrous, deflexed blade surrounded by stiff hairs (Figure 12). This species was previously only known from three widely separated localities, one in the mountains of northern Oaxaca (Salazar & Soto 1996), other two in region known as Huasteca, in Queretaro (García-Cruz et al. 2003) and San Luis Potosi (Fortanelli-Martínez et al 2021).

The first record of the species for the flora of Veracruz state is reported here. The best distribution model for L. papilionacea had an AUC = 0.944, where Bio _ 2 (Mean Diurnal Temperature Range) was the most contributing variable with 43.8 %, followed by Bio _ 5 (Max Temperature of Warmest Month) with 28.5 %, and Bio _ DEM (Mexican Digital Elevation Model) with 26.5 %. The MaxEnt Jackknife test showed that Bio _ 5 (Max Temperature of Warmest Month) was the most contributing variable when used in isolation, thus providing the most useful information. Meanwhile, Bio _ 2 (Mean Diurnal Temperature Range) was the variable that, when omitted, caused the greatest reduction in contribution, suggesting it provides unique information absent in the other variables. The model predicts three areas with high probability for the distribution of L. papilionacea: two of them in the Sierra Madre Oriental, one in its central portion, known as the Huastec region (Queretaro and San Luis Potosi), the other in the southern part of it; Sierras of northern Oaxaca (Figure 13). The adjusted model had a cutoff value of 0.396 and generated a potential occupancy area of 23,842.53 km 2, which corresponds to 1.21 % of the Mexican territory. Lepanthes papilionacea grows as an epiphyte in the cloud forest and Quercus - Pinus forest, ranging between 2000 – 2400 m elevation. In Veracruz it was found growing on Quercus delgadoana, together with Lepanthes salvaterrae, and L. totontepecensis. Flowers between April to November. Conservation status: — Not evaluated by the IUCN Red List or the Extinction Risk Evaluation Method for Mexican wild flora species (SEMARNAT 2019). Additional field studies are required to assess the viability of its populations and the quality of its habitat. Lepanthes papilionacea is known from six disjunct localities (except the two between the border of Queretaro and San Luis Potosi, and the two in northern Oaxaca), with a potential distribution covering 1.21 % of the country’s surface area. Only three populations are protected, one in Oaxaca in forests under community protection, and the other in Veracruz, in the Salvaterra Ecological Reserve. It is also very close to the Cofre de Perote National Park, which could provide additional favorable habitat.	en	Solano, Rodolfo, Licona, Ethian, Carral, Rodrigo, Téllez-Baños, Bruno (2025): Two new species, nomenclatural notes and an updated checklist in Lepanthes (Orchidaceae, Pleurothallidinae) from Mexico.

038887E1FFC4FF8E9AACF919FE296D6D.taxon	distribution	Distribution and ecology: — Currently, this species is a Mexican micro-endemism restricted to the southern part of the Sierra Madre Oriental in Veracruz (Figure 16). Due to the limited number of known localities, all located in a very small area, it was impossible to create a distribution model for this species. However, it is possible that the species may also inhabit nearby municipalities close to Xico. Lepanthes salvaterrae is an inhabitant of the cloud forest, ranging between 2000 – 2160 m elev. It grows as an epiphyte on trunks of Quercus delgadoana, Liquidambar styraciflua Linnaeaus (1753: 999), Vaccinium leucanthum Schlechtendal (1834: 524), and Quercus corrugata Hooker (1841: 403), together with Lepanthes acuminata, L. calopetala, L. moorei, L. papilionacea, and L. totontepecensis. It flowers from August to November.	en	Solano, Rodolfo, Licona, Ethian, Carral, Rodrigo, Téllez-Baños, Bruno (2025): Two new species, nomenclatural notes and an updated checklist in Lepanthes (Orchidaceae, Pleurothallidinae) from Mexico.

038887E1FFC4FF8E9AACF919FE296D6D.taxon	etymology	Etymology: — The specific name comes from Salvaterra, the name of a privately owned forested land ranch that preserve fragments of cloud forest. Located in Veracruz, this land is dedicated by its owners to the conservation of this habitat, where the species was discovered. Additional specimens examined (paratypes): — MEXICO.

Taxonomic discussion: — Lepanthes salvaterrae is recognized among its Mexican congeners by its orbicular to orbicular-elliptic leaves, flowers almost as long as the leaf, cream or pale yellow in color and densely spotted with red-purple, with ovate-lanceolate, acuminate, and glabrous sepals (Figures 14 – 15). The species is florally similar in shape and color to L. gabriellae (Figure 9 A), but it is distinguished by sepals with reddish cilia apparent on their margins (vs. entire sepals), petals with upper and lower lobes similar to each other (vs. lobes different in shape and size), and its narrowly elliptic leaves (vs. orbicular to orbicular-elliptic).	en	Solano, Rodolfo, Licona, Ethian, Carral, Rodrigo, Téllez-Baños, Bruno (2025): Two new species, nomenclatural notes and an updated checklist in Lepanthes (Orchidaceae, Pleurothallidinae) from Mexico.

038887E1FFC4FF8E9AACF919FE296D6D.taxon	description	Conservation status: — Not evaluated by the IUCN Red List nor the Extinction Risk Evaluation Method for Mexican wild flora species SEMARNAT 2019). Although L. salvaterrae is known from various sites, all of them are in the same locality, within a privately owned reserve that protects its habitat. This locality is located close to Xico, a tourist city in Veracruz, where the development of tourism infrastructure could impact the remaining fragments of cloud forest and the habitat of the species. Additionally, this region is affected by the conversion of forests into coffee plantations and increasing urbanization. However, nature tourism activities are offered there, and some coffee producers strive for their products to be organic, which represents conservation-friendly actions. In Veracruz, Rancho Salvaterra ecological reserve includes one of the richest localities for Lepanthes in Mexico, where eight species have been recorded so far: L. acuminata, L. avis, L. calopetala, L. machorroi, L. moorei, L. papilionacea, L. salvaterrae, and L. totontepecensis.	en	Solano, Rodolfo, Licona, Ethian, Carral, Rodrigo, Téllez-Baños, Bruno (2025): Two new species, nomenclatural notes and an updated checklist in Lepanthes (Orchidaceae, Pleurothallidinae) from Mexico.
