Species Descriptions

Two cloud forest species of Lycianthes are newly described: L. breedlovei from the state of Chiapas, Mexico and L. fredyclaudiae from the state of Baja Verapaz, Guatemala. Both species have orange-brown, multangulate-stellate trichomes in which the rays of the trichome are rebranched, white to pale lilac flowers (with darker violet-purple lobes in L. breedlovei), and unequal stamens. Morphologically, they resemble L. hortulana of Honduras, but both new species have previously been misidentified as L. cuchumatanensis. This article provides species descriptions, maps of geographic distributions, drawings of trichomes, and images of the flowers and specimens of the two new species, as well as a comparison chart of morphological characters used to separate L. breedlovei and L. fredyclaudiae from similar species.

Three Panamanian cloud forest species in the genus Lycianthes are newly described: L. coloradensis, from the Ngäbe-Buglé Comarca; L. fortunensis from Chiriquí Province, Veraguas Province, and the Ngäbe-Buglé Comarca; and L. talamancensis from Bocas del Toro and Chiriquí provinces. All three species are woody vines with tan, yellow, or orange-brown multangulate-stellate trichomes and entire to nearly entire white to purple corollas. In terms of vegetative morphology and trichome characteristics, L. coloradensis most closely resembles L. purpusii of Mexico, Guatemala, and Honduras, L. fortunensis resembles the widespread L. multiflora, and L. talamancensis resembles L. hortulana of Honduras, El Salvador, and Nicaragua. This article provides species descriptions, maps of geographic distributions, specimen images of each species, and comparison tables of morphological characters used to separate L. coloradensis, L. fortunensis and L. talamancensis from similar species.

Two New Species

In the present study, two new species of Nitzschia Hassall, Nitzschia pusilluhasta sp. nov. and Nitzschia australodesertorum sp. nov. are described from reservoirs in the state of São Paulo southeast Brazil. The morphology of the new species was analysed using light and electron microscopy. Nitzschia pusilluhasta is distinguished from morphologically related species by its valve outline, the shape of apices and fibulae, the absence of a gap between central fibulae, and the density of striae and areolae. Nitzschia australodesertorum differs from morphologically similar species in its valve outline, the shape of apices and fibulae, the presence of a gap between the central fibulae, and the density of fibulae and striae. The morphology and ecology of the new species are discussed and compared with morphologically related taxa. Information on the co-occurrence of other diatom species in the samples is also provided.

Two New Species

Two new species of Graffenrieda are described from the Amazon rainforest. Graffenrieda maturaca is characterized mainly by its leaves which are dull on the adaxial surface, chartaceous, narrowly elliptic to oblanceolate, and apparently uni-nerved, with only the median acrodromous vein evident. This species has been collected only at Serra de Maturacá, in the state of Amazonas, Brazil. Graffenrieda goldenbergii is distinguished mainly by the pulverulent, whitish, early caducous indumentum of the rachis, pedicel, hypanthium and calyx, by the abaxial surface of the leaves which is moderately lepidote, with trichomes ca. 0.2 mm diam., by the irregularly valvate calyx, and by the membranaceous, costate, not sulcate fruits. This species has been collected in the state of Acre, Brazil, and in the Province and District of Lama in Peru. Both species are illustrated, compared with similar species, and their conservation status is discussed.

Two new freshwater species of amphipods from Brazil are described here. Hyalella xakriaba n. sp. occurs in the hydrographic basin of the São Francisco River, in a biome characterized by a semiarid climate, in the state of Minas Gerais. This new species constitutes the northernmost record of the genus in Brazil. Hyalella kaingang n. sp. occurs in the hydrographic basin of the Mampituba River, located in Rio Grande do Sul, the southernmost state in Brazil. Currently 14 species of Hyalella are known in Brazil, cave species among them. Some morphological characters and their respective states are analyzed, and constitute an important new tool for species identifications. In particular, we describe the cuticular structures, defined as denticles, on the distal inner margin of the carpus of gnathopods 1 and 2. These structures may have a polygonal pattern or appear as comb scales, and may be arranged in one or more rows.

Two New Species

We describe two new species of miniaturized toadlet in the B. pernix group of Brachycephalus (Anura: Brachycephalidae) from the Atlantic Forest of the state of Paraná, southern Brazil. The first new species is distinguished from all congeners by the pale red coloration from the head to the pelvic region, with sides of the body and thighs dorsally yellowish green. It is known only from the type locality in a cloud forest at altitudes ranging between 1,144–1,228 m a.s.l. The second species, although more closely related to B. izecksohni, is morphologically similar to B. brunneus in its overall brown coloration, but distinct from that species in the color of the iris (black with conspicuous golden spots, instead of entirely black). It was found on three mountains, at altitudes between 1,095–1,320 m a.s.l., and in vegetation types including cloud forest, montane forest, and secondary forest. The two new species exhibit neither vertebral fusions nor osteoderms, but one has both a distinct neopalatine and well-developed odontoids on the maxillae. We discuss the conservation status of both species.

Croton (Euphorbiaceae) includes more than 1,300 accepted species and new species of the genus are continuously being described, which are mainly from Brazil. Two new species, Croton aemulus and C. graomogolensis, are herein described, placed in C. sect. Barhamia subsect. Barhamia, and compared to C. muscicapa and C. longibracteatus. The new species are supported by their geographic distributions, ecology, and anatomical and morphological features. Both species are only known from the state of Minas Gerais, Brazil. Croton aemulus occurs in cerrado de altitude (mountain savannah) and C. graomogolensis occurs in campo rupestre (rupestrian grasslands) vegetation.

Abstract We describe two new species of sucking lice in the genus Hoplopleura Enderlein, 1904 (Psocodea: Phthiraptera: Hoplopleuridae) from Australia: Hoplopleura gracilicaudatusa n. sp. from the eastern chestnut mouse Pseudomys gracilicaudatus (Gould) (Rodentia: Muridae), and Hoplopleura nanusa n. sp. from the western chestnut mouse Pseudomys nanus (Gould) (Rodentia: Muridae). Pseudomys Gray is the most speciose genus of rodents endemic to Australia with 24 species; however, only two Pseudomys species have been reported previously to be hosts of sucking lice. The description of the new species in the present study doubles the number of sucking louse species known to parasitize Pseudomys mice and increases the total number of sucking louse species known from endemic Australian rodents from 21 to 23. Pseudomys gracilicaudatus and P. nanus are closely related murines that diverged ~1 MYA with distinct and widely separated extant geographic distributions. The two new Hoplopleura species described in the present study share some morphological characters and likely co-evolved and co-speciated with their chestnut mouse hosts.

Two New Species

Two new species of Aclis Lovén, 1846 are described from the continental slope of northeast Brazil. Aclis macrostoma n. sp. is recorded off the state of Rio Grande do Norte at depths ranging from 375 to 510 meters. Aclis watsoni n. sp. was dredged off the state of Sergipe at depths ranging from 365 to 510 meters. There are no similar species along the Brazilian coast. Aclis watsoni is similar to Aclis angulata Smith, 1890, Aclis trilineata Watson, 1897, Aclis supranitida (Wood, 1842) and Aclis ascaris (Turton, 1819) due to the presence of spiral keels and/or indication of a subsutural ramp. Aclis macrostoma is similar to Discaclis canariensis Moolenbeek & Warén, 1987, Aclis attenuans Jeffreys, 1883 and Aclis gulsonae (Clark, 1850) regarding its circular aperture and dilatation of the peristome, with a non-thickened outer lip. The latter two species are much more slender.
