A new species of arboreal forest viper (Serpentes: Viperidae: Atheris) from a forest fragment in the Southern Highlands of Tanzania is described and named Atheris matildae sp. nov. The species resembles the forest horned viper, Atheris ceratophora Werner, by bearing horn-like supraciliary scales but it differs in size, body proportions, scalation, scale ultrastructure, and distribution. Genetic divergence is also assessed and the two species have an estimated divergence time of approximately 2.2 million years. An overview of the genus Atheris in Tanzania, including new distribution data, is presented and the conservation status of the new taxon is discussed.

Xyliphius anachoretes, a new species of aspredinid catfish is described from the Tocantins-Araguaia River system. Xyliphius anachoretes is diagnosed by the presence of six developed retrorse serrae on posterior border of pectoral-fin spine, presence of papillae on the lower lip bearing minute branches, and only two dorsal procurrent rays. Comments about the informativeness of character-state variation among Xyliphius species and aspredinid related genera are furnished. Also, a brief discussion about conservation status of the new taxon is made.

ABSTRACT We describe and illustrate a new species of Coccoloba (Polygonaceae), named Coccoloba gigantifolia, from the Brazilian Amazon. It resembles Coccoloba mollis Casar, but differs from the latter species by its much larger leaves in the fertile branches. The species has only been recorded in the Madeira River basin, in the states of Amazonas and Rondônia, in the central and southwestern Brazilian Amazon. The description was based on herbarium material, cultivated plants, and individual trees in their natural habitat. We provide illustrations, photographs, and an identification key with morphological characteristics that distinguish the new taxon from the other two related taxa of the Coccoloba sect. Paniculatae, as well as comments on the geographic distribution and conservation status of the species.

Background and Aims: Aristolochia is the largest genus in Aristolochiaceae and is widely distributed in the world. A recent synopsis of Aristolochia in Costa Rica recognized 19 species; nevertheless, recent botanical exploration in southwestern Costa Rica has revealed yet another new species of this genus. Methods: The new species resulted from fieldwork in Buenos Aires, Puntarenas Province. Specimens from several herbaria were examined, as well as the type material of the most morphologically similar species. Comments about its distribution, habitat, phenology, conservation status and morphological distinction from related species are provided.Key results: Aristolochia quiricoana, a member of Aristolochia series Thyrsicae, is described and illustrated from the southern Pacific region of Costa Rica, where it is apparently endemic. It is similar to A. ornithorhyncha, from which it is distinguished by its shorter pedicels, wider, oblong perigone limbs with a shorter appendix, and a different floral color pattern.Conclusions: The new taxon described here represents the 22nd species documented in Aristolochia series Thyrsicae, as well as the 20th species of the genus from Costa Rica.

Themus (Telephorops) davidis species-group is redefined and we present a catalogue, identification key and distribution map for this group. Some previously known species are redescribed and we provide new illustrations of female internal genitalia, abdominal sternite VIII and/or aedeagus. Further, we report new distribution data. A new species, Themus (Telephorops) hainanus sp. nov. from China (Hainan) is described, and Themus (Telephorops) birmanicus Wittmer, 1983 is recorded from China for the first time.

The genus Helosciadium has six species of which three have been identified in Portugal: H. nodiflorum, frequent and abundant in much of the territory, and H. inundatum and H. repens, with a scattered distribution in Portugal. In the present study, a new species, Helosciadium milfontinum, a seriously threatened plant endemic, rare and scarce that grows in the temporary ponds of the Vicentinan Coastal District is described and illustrated. Morphological characters and molecular analysis of nuclear internal transcribed spacers (ITS) and plastid regions (matK, rps16-trnK and trnL-F) confirm the existence of this new taxon. Conservation status and taxonomic relationships of the new species are examined.

Ichnanthus adpressus, a new species of Poaceae regarded as endemic to cloud forests of two areas in Southern Minas Gerais, Southeastern Brazil, is described and illustrated. Morphological similarities between the new taxon and other species of Ichnanthus are discussed. SEM analysis of the upper anthecium in this new species reveales features not yet described for this genus. Comments about phenology, habitat, life history, distribution and conservation status are given.

Oreocharis brachypodus is described and illustrated as a new species from Guizhou, China. The new species is similar to Oreocharis villosa. However, the new species is readily distinguished from the latter by cymes not branched, 1–4-flowered, larger and pronounced gibbous corolla (2.2–2.5 cm long), ovary ca. 1 cm long, with 4 ribs prominent, style ca. 0.7 cm long, and thecae confluent. Comments on affinities, geographical distribution, ecology, phenology and conservation status of the new species are also provided.

In this paper five new records for the Chinese flat bug fauna are reported: Aradus angularis Sahlberg 1886, Aradus betulae (Linnaeus 1758), Aradus distinctus Fieber 1860, Aradus tonkinensis Kormilev & Heiss 1976, and Aradus rysakovi Kiritshenko 1951. Aradus wuzhisanensis Liu 1981from Hainan Province is synonymised with Aradus candidatus Bergroth 1889, a species known from Myanmar, Thailand, and Laos. A new species, Aradus gaoligongensis n. sp. from Sichuan Province, belongs to the “transiens”-group and is described and figured. In addition, new distribution data are given for 8 Aradus species.

Acianthera bilobulata is described and illustrated as new species. Information concerning distribution, habitat, phenology, and conservation status are provided. The new taxon is compared with the most similar species A. pubescens, from which it differs by its elliptic-lanceolate leaves, yellow-cream flowers suffused with red-purple, acute, marginally erose petals, and an oblong, obtuse, marginally entire lip with oblong, rounded lateral lobes. Furthermore, A. bilobulata is compared with other three morphologically similar species, A. breedlovei, A. henrici, and A. majakoluckae.
