1. Burmeistera quimiensis (Lobelioideae, Campanulaceae): A new species from the Cordillera del Cóndor range in southeast Ecuador

   https://doi.org/10.11646/phytotaxa.433.1.7  

   MASHBURN, BROCK; PÉREZ, ÁLVARO J.; PERSSON, CLAES; ZAPATA, NICOLÁS; CEVALLOS, DANIELA; MUCHHALA, NATHAN (February 2020, Phytotaxa)

   A new taxon belonging to the genus Burmeistera (Campanulaceae, Lobelioideae) is described from El Quimi Biological Reserve in Morona Santiago Province, southeast Ecuador. Burmeistera quimiensis is characterized by its red-violet stems and veins, spiral phyllotaxy, bullate, ascending leaves with a revolute margin, puberulous abaxial leaf surface, cupuliform hypanthia, and thick-walled white to red-violet fruits with reflexed pedicels. Photos of the new species are given, as well as a distribution map of known collection localities, and its relationships with other species are discussed.

2. A taxonomic revision of the Strumigenys nitens and simulans groups (Hymenoptera: Formicidae), two Caribbean radiations of leaf litter ants

   https://doi.org/10.11646/zootaxa.4656.2.7  

   BOOHER, DOUGLAS B.; PREBUS, MATTHEW; LUBERTAZZI, DAVID (August 2019, Zootaxa)

   In this study, we revise two groups of cryptic leaf litter ants, the Strumigenys nitens and Strumigenys simulans species groups. These two groups are restricted to the Greater Antilles and the Bahamas. We redefine the species groups, provide a key for the five species in the S. nitens group, and differentiate the two species in the S. simulans group. Four new species are described: Strumigenys caiman sp. nov., S. economoi sp. nov., S. hubbewatyorum sp. nov., and S. zemi sp. nov. We review and provide a key for the Strumigenys fauna of Hispaniola, which comprises the two endemic species S. economoi and S. zemi, six more broadly distributed Neotropical species, and three pan-tropical “tramp” species.

3. Review of the leafhopper genus Thaia Ghauri and related genera (Hemiptera: Cicadellidae: Typhlocybinae: Erythroneurini)

   https://doi.org/10.11646/zootaxa.4868.3.2

   null (Ed.)

   The leafhopper genus Thaia Ghauri, 1962 and two related genera, Parathaia Kuoh, 1982 and Pseudothaia Kuoh, 1982, are revised. Nlunga Dworakowska, 1974, previously treated as a subgenus of Thaia, is elevated to the genus level, and Parathaia Kuoh, 1982, previously treated as a synonym of Thaia, is reinstated to valid status. The Oriental species lacking foveae on the pronotum are excluded from Nlunga and transferred to a new genus, Etmaria gen. n. Two species, Pseudothaia caudata Song & Li, 2013 and Thaia (Nlunga) leishanensis (Song & Li, 2007), are treated as Incertae sedis within Erythroneurini. Moreover, nine additional new species are described and illustrated: Nlunga parareeneni, Etmaria brevis, E. chaiyaphumica, E. dentata, E. indonesica, E. magna, E. triquetra, E. ulterior and Pseudothaia forcipis spp. nov.

4. Six New Species of Burmeistera (Campanulaceae) from Ecuador

   https://doi.org/10.3417/2021589  

   Mashburn, Brock; Ulloa Ulloa, Carmen; Muchhala, Nathan (February 2021, Novon, A Journal for Botanical Nomenclature)

   null (Ed.)

   Six species of Burmeistera H. Karst. & Triana are described as new from Ecuador: B. chrysothrix Mashburn & Muchhala, B. crocodila Mashburn & Muchhala, B. erosa Mashburn, B. lingulata Mashburn & Muchhala, B. sierrazulensis Mashburn & Muchhala, and B. valdiviana Mashburn. These discoveries bring the total number of Burmeistera species in Ecuador to ca. 47. Descriptions are given for each species, as well as diagnoses to differentiate them from other Burmeistera. Also provided is a discussion of each species’ etymology, phenology, and ecology, a list of all specimens examined, and distribution maps and photos, when available.

5. Mallocybe africana (Inocybaceae, Fungi), the first species of Mallocybe described from Africa

   https://doi.org/10.11646/phytotaxa.478.1.3  

   AIGNON, HYPPOLITE L.; NASEER, AROOJ; MATHENY, BRANDON P.; YOROU, NOUROU S.; RYBERG, MARTIN (January 2021, Phytotaxa)

   null (Ed.)

   The family Inocybaceae has been poorly studied in Africa. Here we describe the first species of the genus Mallocybe from West African and Zambian woodlands dominated by ectomycorrhizal trees of Fabaceae and Phyllanthaceae. The new species M. africana is characterized by orange-brown fruitbodies, a fibrillose pileus, a stipe tapered towards the base and large ellipsoid basidiospores. It resembles many north and south temperate species of Mallocybe but is most closely related to the southeast Asian tropical species, M. errata. M. africana is widely distributed in West Africa (Benin, Togo, Burkina Faso and Ivory Coast) extending to South-eastern Africa in Zambia. Phylogenetic analyses based on 5.8S rDNA, nLSU and RPB2 sequence data confirm that M. africana is nested within Mallocybe. A complete morphological description and illustrations, including photographs and line drawings, are presented.
