Two new species of Protonemura Kempny, 1898, P. lupina sp. n., from the Castellane Prealps and the southern Mercantour region in the French Maritime Alps, and P. alexidis sp. n., from the southern flank of the Massif Central, are described, illustrated, and compared to their closest relative species P. risi (Jacobson & Bianchi, 1905) and P. spinulosa (Navás, 1921). Information on distribution and ecological preferences of these new species is provided.

Two New Species

Two new species of Paravelia – P. loutoni and P. reclusa – are described from water-filled bamboo internodes in the forests of eastern Peru. Color dorsal habitus photographs of both species and line drawings of key male genitalic characters are provided, accompanied by a distribution map. Line drawings of the male genitalic structures of P. myersi Hungerford, the closest putative relative to these two new species, are also provided for comparison. Although Neotropical Veliidae have been previously reported from bromeliad phytotelmata, the current results from bamboo internodes are the first records for veliid utilization of this habitat in the Western Hemisphere, and indicate that further samples from such habitats are likely to result in the discovery of other heretofore undetected veliid species. New records are also provided for 12 other previously described Paravelia species; the new records serve to clarify the geographic ranges and ecological preferences of these taxa.

Two New Species

Two new species of Encyonema are described from Central-western Brazil, bringing the total number of species in this genus recorded in Brazil to 45. Encyonema menezesiae has lanceolate valves with the ends subcapitate to rostrate-capitate, whereas E. candangense has linear valves with indistinct ends. The two species show deep alveoli, linear foramina, and densely areolate striae. These characteristics, together with the narrow valves, distinguish E. menezesiae and E. candangense from related taxa. The new species occurred in slightly acid and mostly oligotrophic waters. Similar aquatic environments in this region are being drastically affected by the use of biocides and fertilizers for agriculture. The description of these two species and their ecological preferences may provide useful information for the preservation of aquatic systems and their communities in Brazil.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.

Abstract—Two new diploid species, Aira minoricensis and Aira hercynica, are described and illustrated, along with chromosome counts, risk assessment, distribution and habitat, phenology, and comparisons with morphologically similar species. A comparative table and a key for the species of Aira for the Iberian Peninsula and the Balearic Islands are provided to assist in the identification of these overlooked species, and their relationships to other taxa are discussed.

Two New Species

Abstract Bed-by-bed sampling of twelve Barremian sections in southeastern France from pelagic basin (Vocontian Basin) to neritic platforms (Arc of Castellane, Arc of Nice and Provencal Domain) has enabled the collection of isochronous samples of the ammonite genus Gassendiceras. Three poorly known species of the Toxancyloceras vandenheckei Zone (Upper Barremian) are revised: G. alpinum, G. multicostatum and G. hoheneggeri; two new species are described (G. rebouleti nov. sp. and G. bosellii nov. sp.). The intraspecific variability of particular species was recognised. This variability is between slender peramorphic and robust paedomorphic extreme morphologies, with the presence of all intermediates.

Two New Species

This paper continues the publication of new data obtained during field studies in remote and poorly studied regions of Laos in 2015–2018. It provides descriptions of two new species (Bulbophyllum brachyscapum Aver. and Sunipia saccata Aver.), emended descriptions of two previously published but insufficiently known species (Cleisostoma verrucosum Aver., Oberonia vesiculifera Aver.) and reports of eight species newly recorded in the flora of Laos (Biermannia calcarata Aver., Bulbophyllum farreri (W. W. Sm.) Seidenf., Didymoplexiella trichechus (J. J. Sm.) Garay, Eria eriopsidobulbon C. S. P. Parish et Rchb. fil., Habenaria ciliolaris Kraenzl., Liparis caudata Aver. et K. S. Nguyen, Odontochilus umbrosus (Aver.) Ormerod, and Porpax ustulata (C. S. P. Parish et Rchb. fil.) Rolfe). Appropriate citations of regional literature, colour illustrations, data on types and distribution, descriptions, etymology, as well as notes on taxonomy and related species are provided for the studied species.
