1. No end to endemism – contributions to the difficult Nasa Weigend Series Alatae (Loasaceae). A new species from Peru and the rehabilitation of “ Loasa” calycina Benth.

   Henning, Tilo; Allen, Joshua P; Montesinos-Tubeé, Daniel; Rodríguez-Rodríguez, Eric F; Peña, José_Luis Marcelo; Acuña-Castillo, Rafael (February 2025, PhytoKeys)

   A new species of Nasa ser. Alatae (Urban & Gilg) Weigend from Northern Peru is described and illustrated.Nasa katjaesp. nov.was at first encountered by an observation on iNaturalist and subsequently collected in the humid Andean forests near Colasay in the province of Jaén (Cajamarca, Peru). Whilst comparing the new species with closely relatedNasa loxensis(Kunth) Weigend, a taxon widespread in Southern Ecuador (and tentatively adjacent Peru), a reevaluation of the status of earlier synonymizedLoasa calycinaBenth. became necessary. Consequently,Nasa calycinacomb. nov.is rehabilitated at species level andNasa loxensisis redefined.

2. Bomarea pastazensis (Alstroemeriaceae), an exceptionally small new species from the eastern Andean slopes of Ecuador

   https://doi.org/10.3897/phytokeys.235.110525  

   Clark, John L.; Fierro-Minda, Alisson; Exe, Nolan; Johnson, Mia; Tribble, Carrie M.; Jost, Lou (November 2023, PhytoKeys)

   Recent field research on the eastern slopes of the Andes resulted in the discovery of a new species ofBomareafrom the Cerro Candelaria Reserve in the Tungurahua province of Ecuador.Bomarea pastazensisis the second smallest species in the genus and differs from the smallest by the presence of glutinous trichomes on the ovary, glabrous sepals, and greenish-yellow petals with purple spots. Based on IUCN guidelines, a preliminary conservation status is assigned as Vulnerable (VU).

3. The Rediscovery of Noblella peruviana after More than 115 Years Helps Resolve the Molecular Phylogeny and Taxonomy of Noblella (Amphibia, Anura, Strabomantidae)

   We revise the taxonomy of the frog genus Noblella on the basis of a molecular phylogeny. Previous studies recognized that Noblella is non-monophyletic, with one clade distributed from southeastern Peru to northeastern Bolivia and adjacent areas in Brazil and another clade distributed from northern Peru to Ecuador and southeastern Colombia. The lack of sequences from the type species Noblella peruviana prevented the investigation of its phylogenetic position and the status of related taxa. Our rediscovery after more than 115 years allowed for the inclusion of DNA sequences of Noblella peruviana obtained from specimens collected at the type locality in southeastern Peru. We inferred a phylogeny based on a concatenated dataset (three mitochondrial and two nuclear loci) using Bayesian and maximum likelihood methods. Our phylogeny corroborated the non-monophyly of Noblella and helped resolve the status of related taxa, including Psychrophrynella bagrecito, the type species of the genus Psychrophrynella (rediscovered after 42 years). We identified a clade containing N. peruviana, P. bagrecito, and other species of Noblella and Psychrophrynella distributed in southern Peru. Given that the name Noblella predates Psychrophrynella, we propose that Psychrophrynella should be considered a junior synonym of Noblella. The second clade contains species of Noblella distributed in Ecuador and northern Peru, including N. myrmecoides, which used to be the type species of the genus Phyllonastes. Consequently, we propose to reinstate the genus Phyllonastes to accommodate all species of Noblella distributed in Ecuador, northern Peru, southeastern Colombia, and adjacent areas in Brazil. We present an updated taxonomy including new combinations for 12 species and reinstatements for three species.

4. New species of Coccidella Hambleton and Rhizoecus Kunckel d’Herculais from South America (Hemiptera: Rhizoecidae)

   https://doi.org/10.11646/zootaxa.5555.1.9  

   SCHNEIDER, SCOTT A; LAPOLLA, JOHN S (December 2024, Zootaxa)

   Two new species of root mealybugs (Hemiptera: Rhizoecidae) from South America are described and illustrated based on the morphology of the adult females: Coccidella advena Schneider & LaPolla, sp. nov. from Peru and Rhizoecus peripotaro Schneider & LaPolla, sp. nov. from Guyana and Peru. Both species were collected with colonies of Acropyga ants (Hymenoptera: Formicidae) but only R. peripotaro was found to be trophobiotic; C. advena was ignored by the ants and is considered to be free-living. A guide to aid in identification is provided for each species.

5. Checklist of the genus Dendrophorbium (Senecioneae: Compositae) in Peru including a new combination and a new species

   https://doi.org/10.1111/njb.04385  

   Montesinos‐Tubée, Daniel B (November 2024, Nordic Journal of Botany)

   The genusDendrophorbiumoccurs in South America with one species known from the Caribbean. Despite recent advances in taxonomy and phylogeny, there is a still lack of molecular studies on the delimitation and identification of the genus.Dendrophorbiumis known to occupy a wide range of ecosystems mostly restricted to subtropical montane forests and montane scrub vegetation of the central Andes. In this study, a review of the species occurring in Peru is presented, in addition to material examined at different herbaria. The new combinationD. ligulatumwhich is separated fromD. yalusay, and the new species,D. arachnoideumis described from the department of Huánuco in central Peru. The species are assessed using the standards of the IUCN and additional notes are given.
