The Neotropical genus Mezia (Malpighiaceae) comprises 15 species of lianas (except M. huberi W.R.Anderson, a shrub or small tree). All have multibranched, densely brown-sericeous inflorescences with the ultimate unit a 4-flowered umbel of bilaterally symmetrical flowers. The distinctive pair of large cymbiform bracteoles subtends a rudimentary pedicel and encloses the floral bud. The flowers contain elongate sepals, the lateral four biglandular, yellow petals, the posterior often splotched with red, a heteromorphic androecium, and a tricarpellate gynoecium. The three styles are all free; the posterior pair is lyrate in five species but erect in the others. The samaras have an orbicular to oblate lateral wing and a much smaller dorsal wing; in most species, additional winglets and/or crests are present between the lateral and dorsal wings. Only Mezia mariposa W.R.Anderson has butterfly-shaped samaras lacking additional ornamentation. Four new species are proposed: Mezia andersonii C.E.Anderson, M. bahiana C.E.Anderson, M. fanshawei C.E.Anderson and M. sericea C.E.Anderson. One variety is elevated to species level and provided with a new name, Mezia peruviana C.E.Anderson; a lectotype is chosen for Diplopterys involuta var. ovata Nied. Full descriptions and synonymies are provided, as well as a distribution map. All species are illustrated.

Eastern Species

All 37 eastern species of the genus Pultenaea Sm. with recurved leaves have been revised and two names are reduced to synonymy for the first time. Four new species are described: Pultenaea tarik de Kok, P.�borea de Kok, P.�bracteamajor de Kok and P.�bracteaminor de Kok. One taxon is given a new name: P.�rariflora de Kok (�=�Pultenaea paleacea var. pauciflora C.T.White). Two taxa are recognised in this study at the species level for the first time: P.�elusa (J.D. Briggs & Crisp) de Kok and P.�robusta (H.B.Will.) de Kok. For one species: P.�elachista (F.Muell.) Crisp, a neotype is proposed. Seven species are lectotypified (P.�benthamii F.Muell., P.�densifolia F.Muell., P. gunnii Benth., P.�largiflorens F.Muell. ex Benth., P.�myrtoides A.Cunn. ex Benth., P.�patellifolia H.B.Will. and P.�retusa Sm.). Two species (P.�elusa and P.�maidenii Reader) are considered extinct in this study. A key to the group is provided and a brief discussion is given as to the legitimacy of these species being treated as a separate group. A list of all accepted names and synonyms of the eastern species of Pultenaea is given.

Based on morphological evidence, we propose to raise Tillandsia mauryana forma secundifolia to species level with the name Viridantha secundifolia (Ehlers) Hern.-Cárdenas, Espejo & López-Ferr. Viridantha secundifolia can be readily distinguished by the falciform rosettes, the broadly oblong to square, 1–1.2 × 0.8–1.1 cm leaf sheaths and by the 1.8–2 × 0.7–1.2 cm floral bracts. Additionally, we describe and illustrate Viridantha uniflora Hern.-Cárdenas, Espejo & López-Ferr., from the state of Oaxaca, Mexico. The new species is morphologically similar to Viridantha boqueronensis, but differs by the nearly square leaf sheaths, 1.3–1.5 × 0.4–0.5 cm spikes and by the presence of only one flower per spike. A key to the taxa, morphological descriptions, list of specimens examined, illustrations and a distribution map of the described taxa are included.

Two new species of the genus Gammarus are described and illustrated from Northwest China. A new species name Gammarus tianshan nom. nov. is proposed to replace G. montanus Hou et al., 2004. Gammarus simplex sp. nov. from Altay, Xinjiang, is characterized by uropod III with simple setae on both rami and urosomite I only with setae on dorsal margin. Gammarus glaber sp. nov. from Qinghai, is characterized by uropod III with few simple and plumose setae. Detailed morphological description and differences from related species are discussed. A distribution map of the new species and related species is provided.

A New Species

Abstract—Justicia rubrobracteata, a new species from northeastern Brazil, is described and illustrated. The new species is morphologically similar to J. aequilabris due to its shrubby habit, and terminal and axillary spicate inflorescences with red flowers. However, J. rubrobracteata is differentiated mainly by the shape and color of its bracts and bracteoles as well as an orangish macula in the corolla, and a torulose capsule. In addition, J. rubrobracteata is only known from northeastern Brazil, from the states of Paraíba and Rio Grande do Norte, while J. aequilabris is widely distributed in Bolivia, Brazil, and Paraguay. A table with the main morphological characters of both species is included, as well as photographs, a key to species of Justicia for the states of Paraíba and Rio Grande do Norte in northeastern Brazil, a distribution map of both species, and conservation data for the new species.

A New Species

Abstract—We present a new species, Turnera fasciculifolia, from the Jalapão region, the largest continuous protected area of Cerrado in Tocantins State, in central Brazil. The new species belongs to Turnera series Leiocarpae, and it can be recognized by the linear ericoid leaves with revolute margin, generally without extrafloral nectaries, and the basal leaves of the young axillary branches gathered in fascicles. We provide a description, illustrations, a distribution map, and a comparison with T. genistoides and T. revoluta, which also have ericoid leaves.

Eocene Amber

Embolemidae is a cosmopolitan but species-poor group of chrysidoid wasps with a scarce fossil record, despite a long evolutionary history since at least the Early Cretaceous. Here, the new species, Ampulicomorpha quesnoyensis sp. nov., is illustrated and described based on a single female found in Early Eocene amber of Oise (France). The new species is compared with the three other known fossil species of the genus, and a key to all fossil species of Ampulicomorpha is provided. This is the third European fossil species of Ampulicomorpha, which suggests that the genus was once well established in Western Europe while it is more widely distributed in the Eastern Palaearctic region today. A list of all fossil and extant Embolemidae of the world, as well as a map of their geographical distribution map, are provided.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

The Past

Charophytes in the genus Lamprothamnium exhibit a large amount of diversity, particularly in the examples from Australia, although little of that variation has been recognised at species level in the past. The Australian members of the genus are revised here on the basis of extensive new collections, examination of specimens in herbaria and comprehensive review of the literature and available type material. The existing species Lamprothamnium macropogon (A.Braun) Ophel, L. inflatum (Fil. & G.O.Allen ex Fil.) A.García & Karol and L. heraldii A.García & Casanova are retained, eight new species are described (L. australicum Casanova, L. beilbyae Casanova, L. capitatum Casanova, L. compactum Casanova, L. coorongense Casanova, L. diminutum Casanova, L. macroanthum Casanova and L. stipitatum Casanova) and two taxa variously treated at infraspecific rank in Lychnothamnus are transferred to Lamprothamnium at species rank (L. cockajemmyense Casanova, L. tasmanicum (A.Braun) Casanova). Neither L. papulosum (Wallr.) J.Groves nor L. succinctum (A.Braun) R.D.Wood are confirmed for Australia after examination of the type material of these species. Species are distinguished by the arrangement of the gametangia, morphology of the fertile whorls and characteristics of the oospores. Four of these species are dioecious and nine are monoecious, which supports published conjectures concerning the biogeography of charophyte species (Proctor (1980): J. Phycol. 16, 218–233, doi:10.1111/j.1529-8817.1980.tb03023.x).
