   Three species of Burmeistera discovered during fieldwork in Ecuador are described here. Burmeistera velutina and Burmeistera catulum are unusual in being nearly completely covered in indumentum, short and velvety in the former and remarkably long (up to 4 mm) and silky in the latter. Burmeistera jostii possesses bright red corollas, rare in a genus typically characterized by dull green flowers, and yellow to tan strigose hairs. We provide a discussion of each species’ etymology, phenology, and ecology, a list of all specimens examined, and distribution maps and photos.

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)

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

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

   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.

5. Two new species of Artocarpus (Moraceae) from Thailand and Vietnam

   https://doi.org/10.11646/phytotaxa.453.3.8  

   GARDNER, ELLIOT M. ; CHAVEERACH, ARUNRAT ; SUDMOON, RUNGLAWAN ; ZEREGA, NYREE J.C. ( July 2020 , Phytotaxa)

   Recent taxonomic work on Artoarpus has revealed two undescribed species from Thailand and Vietnam. Artocarpus rubrosoccatus, endemic to peninsular Thailand, resembles A. lacucha but is distinguished by its deep red clavate staminate inflorescences. Artocarpus montanus is found in the montane regions of southern and central Vietnam, and perhaps also in Thailand. This species resembles the vegetative parts of A. lowii and A. excelsus, but A. montanus differs in its longer syncarp processes and its geographic distribution. The vast majority of Artocarpus species are found in tropical lowlands, and A. montanus, along with A. excelsus, represent the only known members of the genus that are restricted to montane habitats. The provisional conservation assessment of both new species is Near Threatened, because although their known areas of occupancy are restricted, both occur in protected areas.
