In the last decade, several species of magnolias have been described for Guatemala, five of which are found in Alta Verapaz, where, during an exploratory survey, we found a specimen that did not correspond morphologically to any previously reported species. To obtain material and determine phenology, several individuals were monitored for a year. Here, we describe this as a new species of Magnolia subsection Magnolia (Magnoliaceae). It is distributed in the cloud forest of San Cristóbal Verapaz, Alta Verapaz, and is culturally important for the local villagers. It differs from other similar species, M. montebelloensis and M. tribouillierana, in having an abruptly acuminate leaf apex (drip tip), larger flowers, purple staminophores and more stamens, among other traits. According to IUCN criteria, M. poqomchi is critically endangered [B1ab (iii), B2ab (iii)]. Additionally, we include a dichotomous key and distribution map for the genus in Guatemala. Taking this record into account, there are a total of ten native species reported for Guatemala, making it an important centre of species diversity for magnolias.

Abstract—Monteiroa rubra is described as a remarkable new species from Rio Grande do Sul, Brazil. It is notably distinct from the other ten species of Monteiroa. The new species is morphologically most similar to the four species of the genus with unlobed leaves that also lack cordate leaf bases. Monteiroa rubra apparently is an endemic species known from three localities in wetlands associated with grasslands in Augusto Pestana and Fontoura Xavier municipalities in southern Brazil. A morphological description, distribution map, photographs, ecological notes, and a key to morphologically most similar species are presented. According to IUCN criteria, if a formal assessment were performed, the new species would probably be considered Endangered.

The new species Chrysophyllum pubipetalum from the Brazilian Atlantic forest of Espírito Santo state is described and illustrated. This new species is characterized by the presence of trichomes on both surfaces of the corolla (a character unique in the genus), channeled petioles, a relatively short pedicel length, and various characters of the fruits and seeds. A distribution map and a table distinguishing the new species from morphologically similar species are also included. As based on IUCN criteria, the species is considered critically endangered.

Reknowned for its high biodiversity and endemism, over one third of the Bornean species of Phyllagathis were discovered in Sarawak over the past two years. In this study, we report an addition of a new species of Phyllagathis, namely P. stellata from southwestern Sarawak. In addition to the taxonomic account, color plates, line drawings, a distribution map, and comparisons with morphologically similar species are provided to aid in identification.

Hypericum bilgehan-bilgilii is here described and illustrated as a new species of section Triadenioides, from the Southern Anatolia, Turkey. Distribution map, habitat and ecology, etymology, the Turkish name for the new species, and dichotomous key are given. The new species is compared with morphologically close species, H. ternatum and H. pallens.

The eastern Nearctic species of the genus Soyedina Ricker, 1952 (Plecoptera: Nemouridae) are reviewed. Two morphology-based species groups are proposed based on epiproct characteristics. Soyedina sheldoni sp. nov. is described from the southern Appalachian Highland region of western North Carolina. A distribution map and a dichotomous key to all nine Nearctic species are provided.

We describe a new species of glassfrog from the cloud forest of Manu National Park, southern Peru, at elevations of 2750–2800m. The new species is similar in morphology to Centrolene lemniscatum, which occurs in northern Peru at elevations of2000–2280 m. Both species have white labial stripes, humeral spines, and lack vomerine teeth. The new species differs from C.lemniscatum by its larger size, labial stripe extending into a distinct lateral stripe instead of a discontinuous lateral stripe, snoutprofile inclined anteroventrally instead of bluntly rounded, greater depression in the internarial area, and by having stronglyprotruding nostrils. Males of the new species emit long calls with 8–14 peaked notes, instead of a short tonal note in C. lemnis-catum. Another morphologically similar species, C. buckleyi, has a short advertisement call composed of 1–5 notes, and isgenetically distinct from the new species. This new Centrolene extends the known distribution of Centrolene to the south by 600 km, and is the southernmost species of this genus.

Werneria lanatifolia is described as a new species from the central Andes. It is a minute plant characterized by a lanate indumentum on the adaxial leaf surface and involucre. The new species is compared with the morphologically closest taxa and useful characters for its proper identification are provided. Detailed pictures of living plants, a distribution map, and a dichotomous key including the species allied to W. lanatifolia are also presented.

Myrcia amplifolia, a new species from the coastal forest of southern Bahia, eastern Brazil, is here described and compared with morphologically similar species. Additionally, a morphological plate, distribution map and conservation assessment of the species are presented. We assign the new species to Myrcia sect. Calyptranthes with a reasonable reliability due to the combination: presence of cataphylls, inflorescences sympodially branching at the base and calyptrate flowers. Myrcia amplifolia seems to be closely related to M. carioca, from which it can be distinguished through the leaf blades strongly coriaceous (vs. chartaceous in M. carioca), leaf venation very slightly raised and barely conspicuous abaxially (vs. venation strongly raised and conspicuous abaxially), inflorescences with a shorter main axis (75–110 mm long vs. 130–270 mm long), and shorter first lateral branch (3.3–19 mm long vs. 48–95 mm long), and the calyptra acuminate (vs. rounded or shortly apiculate). It is also similar to M. boanova, differing by the leaf blades significantly larger (31–60 × 10–20 cm vs. 7–13 × 4.1–5 cm in M. boanova) and strongly coriaceous (vs. chartaceous), and the calyptra acuminate (vs. rounded) and smaller (2.3–2.6 × ca. 1.8 mm vs. 3.5–3.7 × 3.5–4 mm).

We describe Dinacoma sanfelipe sp. nov. from southern California, the first new species belonging to the melolonthine scarab beetle genus Dinacoma Casey, 1889 (Scarabaeidae: Melolonthinae: Melolonthini) to be described in 90 years, based upon examination of 141 specimens of that genus. Diagnostic comments, a dichotomous key, photographs of all species of Dinacoma, and a distribution map are presented to facilitate the identification of adult male specimens.  One species in the genus is federally listed under the United States Endangered Species act, and all known species may be of conservation concern. Key words: Scarabaeoidea, Melolonthini, scarab beetle, insect conservation, cryptic species
