Two new species of Pontederia are here described and illustrated. Pontederia gigantea is similar to P. sagittata by its sagittate leaf blade, but the first one presents blue flowers while the second one has whitish to pinkish flowers. Besides that, P. gigantea is endemic to Brazil, occurring in small populations through the east coast, in the Atlantic Rainforest. Meanwhile, P. sagittata occurs in the south of Mexico and Honduras. Pontederia reflexa occurs disjunctly in South America, in Northeastern Brazil, where its distribution is linked to semiarid areas; and in Bolivia, Paraguay and Brazilian Pantanal. This species is related to the whitish-flowered species of Pontederia, and is differentiated from other species of Pontederia by the reflex and revolute spathe. An updated identification key to species of Pontederia and a map showing the geographic distribution of the new taxa are also provided.

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.

Morphological Differences

The tabanid tribe Diachlorini (Diptera) is the most genus-rich tribe in the Tabanidae; the tribe is cosmopolitan, but the greatest species richness and morphological diversity are found in the Australasian and Neotropical Regions. A new arrangement for the species of Acellomyia González is given; Acellomyia lauta (Hine) is transferred to a new genus, Montismyia gen.n., based on its morphological differences from Acellomyia and geographical distribution. The morphological differences between Acellomyia and Montismyia gen. n. are discussed. Two new species, Acellomyia casablanca sp.n. and Acellomyia puyehue sp.n., are described from specimens collected in southern Chile. Comparison of the morphology of Acellomyia paulseni mapuche (Coscarón & Philip) stat.nov. indicate that they should be elevated to species rank. A key to species of Acellomyia is provided and diagnostic characters are illustrated.

Brazilian Pantanal

Isoetes dubsiisp. nov. and I. santacruzensissp. nov., two new species from lowland areas in South America, are described, illustrated and compared to similar species. Isoetes dubsii can be distinguished from other species of the Brazilian Pantanal wetlands by a set of characters including leaves that are long, flexuous and trigonal in transverse section, tri-lobate stems, rudimentary velum, pustulate megaspores of 310‒390 µm diameter and laesurae of the megaspore at least four times wider than high. Isoetes santacruzensis has flexuous, filiform leaves, 0.4–0.8 mm wide at mid length and reaching up to 15 cm long, black or reddish-black sporangia, sclerified phyllopodia and sparsely verrucate megaspores of 320‒390 µm in diameter. We also include a key for species from the Brazilian Pantanal wetlands and Bolivia and spore images for all species that are discussed. Isoetes dubsii and I. santacruzensis are only known from their type localities and they may deserve special attention concerning their conservation status. However, based on our current knowledge on these species and according to IUCN Red List criteria, they are assessed here as data deficient (DD).

Two new species of Cryptanthus from Bahia State, in northeastern Brazil, are described and illustrated. Cryptanthus apiculatantherus occurs in Atlantic Forest and Cryptanthus brevibracteatus was discovered in a transition area between Atlantic Forest and Caatinga. Cryptanthus apiculatantherus and C. bibarrensis have similar stem lengths and leaf blade shapes, but differ mainly by the stem diameter, width of the leaf sheaths, sepal and petal color, anther apex shape, and length and width of the ovary. Cryptanthus brevibracteatus and C. warren-loosei have a similar leaf blade color and are geographically close to each other, but differ by the number of flowers in the apical cluster of flowers of the inflorescence, length and width of the floral bracts, length of the sepals, connation of the sepals and length of the sepal lobes. Data about the geographic distribution, habitat, phenology, conservation status, taxonomic comments, a distribution map and photographs of the new species are provided. In addition, there are tables included that compare the new species to morphologically similar species.

The fasciolariid fauna from two expeditions to French Guiana is examined and augmented with published records and material of other collections from the Guianas and northeastern Brazil. Twelve species of Fasciolaria and Aurantilaria (Fasciolariinae), Aristofusus, Lyonsifusus and Fusinus s.l. (Fusininae), and Lamellilatirus and Polygona (Peristerniinae) are reported and discussed. Nine species are represented in expedition collections, and reports of three other species are evaluated. Two morphologically distinct species of Lamellilatirus are described as new; type localities of both are off French Guiana, 114–118 m. Ten Guianan fasciolariids range variously northward to Caribbean South America and the Lesser Antilles and southward to Ceará, Brazil; one other extends into the northern Caribbean, and one extends southward to Rio de Janeiro, Brazil.

Species Being

Cryptopontius is the most species-rich genus in the family Artotrogidae with 25 species, being recorded in almost all oceans, except in the Arctic. However only three species of this genus have been recorded from the Brazilian coast, all of them along the coast of Pernambuco state. This study describes two new species of the genus. Cryptopontius phyllogorgius sp. nov. differs from other species by having 9-segmented antennule, and nine elements on the third exopodal segment of leg 4. Cryptopontius pentadikos sp. nov. differs from its congeners by having five expressed antennulary segments proximal to fused ancestral IX-XII, two setae on second endopodal segment of leg 1, eight elements on third exopodal segment of leg 1 and the free segment of leg 5 with two setae. A key to species of the genus Cryptopontius is provided.

The genus Hoplonannus McAtee & Malloch, 1925 is composed of H. brunneus, H. paenebrunneus, H. craneae, and H. australis, all previously recorded from Central and South America. In this paper, we describe Hoplonannus bifidus sp.n. and Hoplonannus robustus sp.n. based on several specimens collected in the Brazilian Amazon, representing the first record of the genus from northern Brazil. We provide diagnoses, photographs of habitus, scanning electron micrographs of male genitalia, and illustrations of female genitalia. A key to species based on males of Hoplonannus is also presented.

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.
