[Botany • 2026] Puya ukumari (Bromeliaceae: Puyoideae) • A New montane bromeliad Species from southeastern Peru


Puya ukumari  Treviño, Yuca & Gouda, 

in Yuca-Palomino, Mamani-Mayta, Champi-Charalla, Condori-Cuti, Llacta-Gomez, Treviño-Zevallos, Gouda, Forsyth, Whitworth et Pillco-Huarcaya, 2026.

Abstract
Montane forests of the Tropical Andes are among the most diverse and endemic-rich ecosystems in the world; however, they remain insufficiently documented, particularly in remote and topographically complex landscapes. Here, we describe Puya ukumari sp. nov. (Bromeliaceae), a new species from humid montane forests and forest–puna ecotonal habitats in the Kosñipata and Mapacho valleys of southeastern Peru, occurring at elevations between 2,300 and 3,300 m a.s.l. The species was first detected during a long-term ecological monitoring program in the region but remained unrecognized for several years due to the limited number of recorded flowering individuals. Its taxonomic identity became evident following the observation of flowering plants during field surveys conducted in 2025. Puya ukumari resembles P. lineata in possessing a simple, nodding, dark-colored inflorescence; however, it is readily distinguished by its considerably larger flowering plant height (160–200 cm vs. 40–80 cm), significantly wider inflorescence diameter (11–12.5 cm vs. 3.5–6 cm), larger lanate sepals (30–33 × 15–18 mm vs. 13–18 × 6–10 mm and floccose), and markedly darker, nearly black petals. These characters support its recognition as a distinct taxon within the group of Puya species with simple inflorescences. The species is currently known from a limited number of confirmed localities within a restricted elevational range. Based on its distribution and the observed threats to its habitat, a preliminary conservation assessment suggests that it should be classified as Endangered (EN) according to IUCN Red List criteria.

Key words: Bromeliaceae, montane forest, Peru, plant taxonomy, Tropical Andes

Puya ukumari Treviño, Yuca & Gouda, sp. nov.
 
Diagnosis. Puya ukumari is similar to P. lineata but is readily distinguished by its much larger flowering size (160–200 cm vs. 40–80 cm), significantly wider inflorescence (11–12.5 cm in diameter vs. 3.5–6 cm), and much larger sepals (30–33 × 15–18 mm vs. 13–18 × 6–10 mm), which are lanate in P. ukumari and floccose in P. lineata, as well as by its markedly darker petals (nearly black vs. blue).

Etymology. The specific epithet ukumari is a noun in apposition derived from the Quechua word “ukumari”, meaning Andean bear (Tremarctos ornatus). The species is dedicated to the Andean bear in recognition of the ecological importance of Puya species as a key component of its diet and of their close association within Andean montane ecosystems.

[Herpetology • 2026] Liolaemus arequipensis • Taxonomic Nightmare: Hard Species Delimitation in Liolaemus (Squamata: Liolaemidae) Lizards of the Peruvian High Andean Plateau with a Description of A New Cryptic Species


Liolaemus arequipensis 
Huamaní-Valderrama, De la Riva, Salas, Santa-Cruz, Salazar, Sites & Aguilar-Puntriano, 2026


Abstract
Liolaemus species are the only lizards inhabiting the cold and hypoxic environments of the high Andean plateau. However, delimiting species within the Liolaemus montanus group across this region remains exceptionally challenging. Two taxonomically difficult groups in this area, the L. annectens and L. signifer complexes, comprise valid species and unassigned populations that require extensive taxonomic revision using modern species delimitation approaches. In this study, we perform phylogenetic, single-locus species delimitation and nuclear network analyses on these complexes. Our results show that within the L. annectens and L. signifer complexes, three and one lineages, respectively, are congruent with mitochondrial evidence and at least one haplotype network. L. annectens is supported by mitochondrial evidence but lacks unique haplotypes in both nuclear networks, and L. signifer shows inconclusive support by both mitochondrial and nuclear evidence. Based on these molecular results and morphological analyses, we describe a new Andean cryptic species, Liolaemus arequipensis sp. nov. from southern Peru.

Abstract
We describe two fossil turtle shells of Chelus colombiana from Middle Miocene vertebrate localities in the Fitzcarrald Arch and Iquitos regions of Peru. One specimen represents one of the most complete fossil shells of the genus, also one of the largest known, measuring 84.6 cm in carapace length and estimated to have weighed approximately 65 kg. Morphological comparisons confirm synchronous consistency with other C. colombiana specimens from Colombia and Brazil, with only minor variation in the gular and extragular scutes. These new records extend the known geographic distribution of C. colombiana to the southwestern margins of the Pebas wetland system and support a broader pattern of body size gigantism among Miocene South American turtles, likely driven by ecological connectivity rather than climatic factors. However, the absence of associated cranial material remains a major obstacle to fully resolving the taxonomy of fossil Chelus, a problem further explored in this study.

[Botany • 2026] Neea myrciifolia (Nyctaginaceae: Pisonieae) • A New Species discovered in central Peru

 

Neea myrciifolia  D.S.Costa & Farroñay,

in Costa, Farroñay, Rossetto, Gonzáles et Giacomin, 2026. 

Summary
Neea myrciifolia D.S.Costa & Farroñay (Nyctaginaceae, Pisonieae) a new species found exclusively in central Peru, in montane forest remnants, is here described, more than 90 years after the last Neea species was described for the country. Images of the morphological structures, a distribution map and a provisional conservation status of the new species, as well as taxonomic notes on morphologically similar species, are provided.

Key Words: endemism, Neotropical flora, Pisonieae, Reserva Comunal Yanesha, taxonomy

Neea myrciifolia D.S.Costa & Farroñay, sp. nov. 

Recognition. Neea myrciifolia can be easily distinguished from all other species in the genus by a unique combination of vegetative and reproductive characters: opposite leaves with abaxial surface with a verrucose texture covered with sparse, pubescent to tomentose, reddish trichomes, globose 2-branched inflorescences with tubular staminate and pistillate flowers and patent, open, deltoid perianth lobes.

Etymology. The specific epithet "myrciifolia" refers to the vegetative resemblance, e.g. opposite leaves and brochidodromus venation, to the genus Myrcia DC. (Myrtaceae).

[Mammalogy • 2026] Phylogenomics and Museomics reveal Five distinct Species of Tiger Cats (Carnivora: Felidae: Leopardus) in South America

 

Leopardus tilcayo  Nogales-Ascarrunz, Aliaga-Rossel, Lescroart & Eizirik, 

in Lescroart, Nogales-Ascarrunz, Cassatt-Johnstone, Bonilla-Sánchez, ... et Eizirik, 2026. 

Highlights: 
• First discovery of a novel cat species in over a century: Leopardus tilcayo
• Description of a novel cat subspecies: Leopardus tigrinus antisuyo
• Phylogenomic resolution of the tiger cat complex, revealing five distinct species
• Museomics and novel approaches to assess evolutionary history and genomic diversity

Summary
The evolutionary history of elusive organisms can be characterized through genomic analyses, which have the power to reveal previously unknown taxa even in groups assumed to be well studied, such as cats. We have analyzed complete genomes of 38 individuals from the Neotropical cat genus Leopardus, including 26 individuals representing multiple evolutionary units of the contentious tiger cat (Leopardus tigrinus) species complex. Eight genomes were generated from museum specimens, which allowed the first genetic assessment of the type locality for L. tigrinus in the Guiana Shield. We found that this complex comprises five distinct species, including a novel cat species, discovered in the Bolivian Yungas and described in this study as L. tilcayo. The Peruvian Yungas unit of this complex also represents a distinct taxonomic entity, which we describe here as a novel subspecies, L. tigrinus antisuyo. Our phylogenomic analyses resolve the evolutionary relationships among the tiger cat geographic units, thus stabilizing their recalcitrant taxonomy and enabling adequate conservation assessment of these threatened felids. We also address other aspects of their evolution, including biogeography, past episodes of interspecies admixture, demographic history of each taxonomic unit, and temporal changes in genetic diversity. Altogether, our results clarify the evolutionary history of a complex radiation of wild cats, reveal novel taxa, and serve as a basis for conservation planning on behalf of these elusive wild cats.

Leopardus tilcayo sp. nov. Nogales-Ascarrunz, Aliaga-Rossel, Lescroart & Eizirik 

Type material: Holotype: CBF-11990, adult male. Live-captured and held in captivity, genome sequences NCBI SRA accession SRX30196846. Date: 09-2021; collectors: E. Aliaga-Rosel and P. Nogales-Ascarrunz (see Data S1).

Type locality: La Paz, Nor Yungas, near Arapata village (1,570 m above sea level [a.s.l.]), Bolivia. Coordinates: −16.248594, −67.634691 (WGS84).

Etymology: This species is named after the local name “tilcayo” used for this felid, which is widely known in the Bolivian Yungas zone. The name is treated as an unchanged noun in apposition.
Vernacular name: We propose “tilcayo” as the English common name, preserving the traditional local designation in recognition of its cultural and regional relevance.
Diagnosis: Leopardus tilcayo differs from L. pardinoides by its shorter pelage, lower contrast pattern, more expanded and irregular open rosettes, less bushy tail, and the absence of broad and complete caudal bands (see Data S1). It differs from L. tigrinus by its larger and more irregular flank markings, longer and fuller tail, and irregular caudal blotches. It differs from L. guttulus by its larger, more heterogeneous markings, lower dorsal contrast, and relatively longer tail. L. tilcayo can be distinguished from other Leopardus taxa by a large number of molecular characters. In the nuclear genome, among the 29,288,951 transversion variants, on average 1,392,646 sites differentiate L. tilcayo from L. t. antisuyo and 1,491,301 sites differentiate L. tilcayo from L. pardinoides. For simplicity we provide a list of diagnostic mitochondrial DNA sites (see Data S1).

[Herpetology • 2025] Liolaemus misti • A New Species of the Liolaemus walkeri clade (Squamata: Liolaemidae) in the volcanic chain of Arequipa, Peru


 Liolaemus misti 
Santa-Cruz, Canazas-Terán, Bejarano, López, Morales, von May, Catenazzi & Aguilar- Puntriano, 2025
   
 Salamandra. 61(2); 

Abstract 
 We describe a new species of Liolaemus lizard from southwestern Peru, within the volcanic chain represented by the Chachani, Misti and Pichu Pichu volcanoes that surround the city of Arequipa. Te type locality is Simbral, in the district of Chiguata, Department of Arequipa. Te diagnostic characters of the new species include small size (SVL < 50 mm), a pigmented subocular scale, vertebral line generally absent or highly fragmented (when present), scales smooth or slightly keeled on the dorsal side of thighs, partial or total ventral melanism, and absence of precloacal pores in males and females. Te elevational distribution of the new species is 4135–5400 m a.s.l., with the upper limit representing the highest altitude record for a living squamate. 

Key words. Andes, high elevation, lizard, systematics, taxonomy.


Adult male holotype of Liolaemus misti sp. n. in life (MUSA 5708), SVL 49.1 mm, TL 55.0* mm.
(A) Dorsolateral, (B) ventral, (C) lateral head, (D) dorsal, and (E) absent precloacal pores. [* = Regenerated or broken tail.]

Adult female paratype of  Liolaemus misti sp. n. in life (MUSA 5709), SVL 45.5 mm, TL 45.2* mm.
(A) Dorsolateral, (B) ventral, (C) lateral head, (D) dorsal, and (E) absent precloacal pores. [* = Regenerated or broken tail.]



Liolaemus misti sp. n.  

Diagnosis: We assign Liolaemus misti sp. n. to the L. walkeri clade, lizards with throat or belly melanistic or with spots in males (Aguilar et al. 2013), small and slender (49.3 mm maximum SVL). Males of L. misti sp. n. differ from L. chavin and L. wari by their smaller size (less than 50 mm SVL vs 51.7–59.3 mm and 51.5–60.8 mm, respectively). Liolaemus misti sp. n. difers from L. tacnae by a lower number of midbody scales and dorsal scales (40–50 vs 48–59, 43–55 vs 53– 61, respectively). Te subocular scale and loreal scales are strongly pigmented in L. misti sp. n. whereas in L. walkeri these scales are lighter (Fig. 7). Te lateral felds in L. misti sp. n. have scattered black and white scales forming spots (males) or scattered black and brown scales (females), which are absent in L. pachacutec. Paravertebral marks appear as black complete marks or as fragmented lines (more noticeable when parallel to the dorsolateral stripe) in L. misti sp. n. (Figs 8A–9A), but they are absent or fuzzy in L. pachacutec; L. tacnae has paravertebral markings as black dots perpendicular to the dorsolateral stripe, with light scales behind the black scales (Figs 8C–9C). Te vertebral line is generally absent or highly fragmented in L. misti sp. n., but it is well diferentiated in L. chavin, L. pacachutec, L. walkeri, and L. wari. Liolaemus tacnae has keeled scales on the dorsal side of thighs, which are absent in L. misti sp. n. (Fig. 10). Liolaemus misti sp. n. also difers from L. pachacutec, L. walkeri, and L. wari in males lacking precloacal pores.

In Peru, three species of the L. alticolor-bribonii group have been confused with species of the L. walkeri clade: L. alticolor from Puno, L. chungara from Tacna, and L. incaicus from Cusco (Aguilar et al. 2013, Lobo et al. 2007, Quinteros et al. 2014, Valladares et al. 2021). Here we report key morphological diferences between these species and L. misti sp. n. Liolaemus misti sp. n. has 49–58 scales around the body, more than L. incaicus (34–46). Liolaemus misti sp. n. lacks keeled temporal scales which are present in L. chungara, L. incaicus (weakly keeled), and L. alticolor (markedly keeled). Dorsal scales in L. misti sp. n. are keeled and without a mucron, whereas a mucron is present in L. chungara. Liolaemus misti sp. n. has partial or total ventral melanism, which is absent in L. alticolor and L. incaicus. Liolaemus misti sp. n. lacks precloacal pores in males and females, which are present in some or all females of L. incaicus, and present in males of L. alticolor, L. chungara and L. incaicus.

Etymology: The scientifc epithet “misti” refers to the volcano Misti, in Quechua language means “a white man” referred to the snow or white blanket that covers the volcano, one of the greatest symbols and the most striking element of the landscape of the city of Arequipa. Misti is the most distinctive volcano of the three that surround the city, along with Chachani and Pichu Pichu. Arequipans say: “not in vain is one born at the foot of a volcano”, the presence of the Misti greatly infuences the noble spirit of its inhabitants.

[Arachnida • 2026] Latrodectus lucacha • A New Andean Species of Widow Spider (Araneae: Theridiidae: Latrodectus)


Latrodectus lucacha  
 Miller, Kratzer & Griswold, 2026

 
Abstract
We describe a new species of widow spider (Araneae, Theridiidae, Latrodectus) from the Andean region. DNA barcode sequences are provided. The species is documented from museum specimens across Peru and identified from photographs on iNaturalist, extending its inferred distribution into Ecuador, Bolivia, and Chile. We integrate specimen and citizen-science occurrences to generate a species distribution model using WorldClim bioclimatic variables, predicting highest suitability along temperate to high-elevation Andean regions. We discuss the utility and limitations of citizen-science imagery for delimiting and mapping species and summarize available information on clinical aspects of envenomation in Peru associated with the local “lucacha” widow spider.

[Botany • 2026] Telipogon vasqueznunezii (Orchidaceae: Oncidiinae) • A New Species for Northern Peru

 

Telipogon vasqueznunezii C.Martel, Chamaya & Iberico,
  
in Martel, Chamaya Gonzáles, Ibérico Vela, Edquén, Rodríguez et Iturralde. 2026. 

Abstract
Telipogon is a highly diverse genus in the Andes, yet it remains incompletely documented in northern Peru. Telipogon vasqueznunezii is morphologically similar to T. hystrix but differs in the oblong-ligulate lip, the two small lobes at the lip base, the absence of a protrusion on the lip, and the tuft of acicular setae on the columnar appendix. A detailed description, illustrations, a distribution map, and a conservation assessment are provided here.

Telipogon vasqueznunezii C.Martel, Chamaya & Iberico, sp. nov. 

Diagnosis: Telipogon vasqueznunezii is most similar to Telipogon hystrix (Dodson) N.H.Williams & Dressler but is distinguished by the larger flowers (9–11 × 8–13 mm vs. 5 × 5 mm), the obovate to sub-oblong petals (vs. narrowly ovate), the oblong-ligulate lip (vs. elliptical to oblong), the sub-auriculate lip base with a pair of small lobes (vs. the sagittate base with two long lobes), the absence of a protrusion on the lip (vs. a hump-like protrusion on the lower half), and one tuft of acicular setae on the columnar appendix (vs. one tuft of setae with a stellate apex on the columnar appendix).

Eponymy: The species is named after Dr Leopoldo Pompeyo Vásquez Núñez, a Peruvian botanist and professor at Universidad Nacional Pedro Ruiz Gallo. Professor Vásquez has dedicated his life to better understanding the plant diversity of northern Peru with a focus on potentially useful plants.

[Herpetology • 2026] Stenocercus aguilari • Morphological and Genetic Evidence support New Species of Stenocercus (Iguania: Tropiduridae) from the Peruvian Andes

  

  Stenocercus aguilari  
Castillo-Urbina, Rios-Roque, Barrera-Moscoso & Mendoza, 2026
 

Abstract
The genus Stenocercus comprises a diverse group of 80 recognized species distributed across South America, with approximately 65% (52 species) occurring in Peru. The Department of Ancash, situated in the central Andes and encompassing the Cordillera Negra and Cordillera Blanca, is a topographically complex region marked by prominent geographic barriers that may promote allopatric speciation and influence patterns of Andean biodiversity, particularly within Stenocercus lineages. Populations previously assigned to S. chrysopygus from the puna habitats of Ancash exhibit notable variation in diagnostic traits and coloration, suggesting that this taxon may represent a species complex. However, inconsistent morphological diagnoses and limited genetic data have hindered accurate taxonomic resolution, underscoring the need for integrative approaches. Furthermore, a recent study showed that only populations from the Santa River Valley correspond to S. chrysopygus sensu stricto, while the other populations assigned to the distribution of S. chrysopygus constitute lineages of different species. In this study, we describe Stenocercus aguilari sp. nov. from Huari Province, Ancash Department, and present a phylogenetic hypothesis of its position based on the mitochondrial ND2 gene. We applied multivariate morphological analyses of scale counts using MANOVA and Gaussian Mixture Models, as well as molecular species delimitation approaches based on both distance-based and tree-based single-locus methods. All analyses support the taxonomic distinctiveness of S. aguilari sp. nov. Morphologically, the new species belongs to the group characterized by granular scales on the posterior surface of the thighs, vertebral scales similar in size and shape to adjacent rows, and three caudal whorls per autotomic segment. It is distinguished from other members of this group by the absence of a posthumeral mite pocket, the presence of a Type 1 postfemoral mite pocket, higher number of midbody scales and the presence of a distinct black patch on the pelvic region of the venter in adult males. Finally, the focal lineage is divergent from all nominal species in the Stenocercus genus for which respective data are available by >14.8% uncorrected pairwise distance in the ND2 gene.
